Following a great link from Mitch at Chemical Forums, there is a chemistry musical video called “Resistant to Base” that is just hilarious. Have a look. Mitch runs a really good blog.
Fog Index
According to Chemical Blogspace, a website that collates blog posts and does a bit of linguistic analysis on the text, this blog has a Gunning Fog index of 13.6. Apparently, Al Gore’s writing generates the same Fog Index. Jeepers.
I’m glad they aren’t grading my sentence construction and punctuation. Or are they … ?
Gastronaut
I’ll admit to being a “Gastronaut”- someone who is driven to seek out and explore new dining and food experiences. I enjoy the fine and unusual restaurant experience. I like good service and exquisite food. One of my favorite foodies is Anthony Bourdain. He wrote a book a few years ago called “Kitchen Confidential“, the gastronomic biography of a hard working, hard drinking cook and graduate of the CIA. Bourdain understands food and what motivates people to seek an unusual dining experience. He is a gastronomic cognoscenti who can cuss and spit like a sailor.
Having been in the sales game, I have had the chance to dine in some really fine restaurants all over the northern hemisphere. I’ve dined in a fantastic Georgian restaurant in Moscow featuring armed guards and metal detectors, London’s Indian restaurants, steak houses in Houston, BBQ joints in San Antonio, haute cuisine in New Orleans, Las Vegas (yeah, baby!!), & Tokyo ($$$), perogies in South Bend, god-knows-what in Taipei, pork tenderloin in Iowa, salmon in Seattle, cheese in Holland, really expensive Cognac in Paris, vodka in Perm, pastrami in Manhattan, and on and on. My god it’s been a great ride.
I’ll never forget the transcendental gastronomic experience I had on Bourbon Street in New Orleans. It was a dish featuring a hard boiled egg with the cap sliced off exposing the yoke, nestled on a slice of toasted bagette with truffle shavings and a truffle sauce. With it I had a glass of a fine Merlot. I can still recall the comingled flavors of truffle and the smokey/woody/currant aspect of the Merlot. Jesus, I’m drooling on the keyboard …
But what I really miss when I travel and what I crave when I get home to Colorado is some good, hot & sassy Mexican food. The kind that is titrated with jalapeno and crinkles your cheeks like hot cellophane when you eat it. If you don’t have sweat running down your forehead and you’re not suckin’ down icewater like a fiend, you haven’t hand the full experience.
Chemical Pricing
I never cease to be amazed at how the market can drive down pricing on even the oldest, most venerable products on your product list. I’m not talking about the prices in the Aldrich or Strem catalogs. Catalog prices are basically of a retail nature and are set in an atmosphere of open information. That is to say, pricing can be set against a background of easily available competitive intelligence. If you want to be competitive, you can match or undercut your competitors pricing.
This discussion pertains to specialty chemicals, as opposed to commodity chemicals. There is a large difference in the pricing approaches in these two market domains. Commodity chemicals are the domain of high volume, low margin. Raw material costs tend to be price drivers. Commodity chemicals are frequently made with continuous flow processing and the economy of scale has been maximized to the fullest. Many commodity chemicals are actually economic indicators- sulfuric acid, superphosphate, hydrocarbons, etc.
There are several ways to set prices of a chemical product. One way is to calculate your unit costs and add your profit by applying a predetermined multiplier for the markup. This is the cleanest way from the accounting point of view. It allows for easier sales forecasting too. If you can estimate the unit sales for the year, you can estimate the expected profit as well. This helps immensely if you need to plan for capital expenditures with your future cash flows. And if you are in a growth period, this can be critical.
In a rational setting, pricing is optimized to afford maximum profit. Pricing needs to be low enough to attract a maximum of orders, but high enough to afford a maximum profit. Notice the use of the word “maximum”. Profit is about extrema on curves. You seek to find the cost minima and profit maxima. Sounds straightforward enough.
But pricing is rarely a purely rational decision. In the commodity arena, raw materials are also commodities and their rough pricing is readily available to all players. Their negotiated prices may not be, though. But by and large, commodity raw material costs are fairly well understood by all. In the commodity arena, pricing should be most “rational”.
In the chemical specialty arena, that is, the arena of non-commodity chemicals, there is a greater chance that pricing may not be entirely rational. That is to say, absolute or global cost minima may not have been found and profit maxima may not have been realized.
Specialty chemicals are for the most part lower volume, higher margin, products where labor costs are often the driver. They may be “Fine Chemicals”, which I’ll define as public domain products that are above what you might call a “technical grade”. Public domain products are those products that are free in composition to any and all buyers. However, while many chemicals are public domain in composition of matter, they may be severely restricted in “use”.
A specialty chemical, by it’s nature as a lower volume domain, is subject to pricing complications that commodity chemcials may not be. Many chemical catalog companies have a bulk chemicals division that isn’t easliy visible to the R&D scale consumer. While their bulk product list may be generally available, pricing is often obtained only through a quoting process. In other words, bulk pricing isn’t posted for all to see. To get a bulk price you have to ask for a quote, which means revealing your identity and how much of what product you need. Bulk specialty chemical business tends to be fairly secretive about pricing. One way around having to disclose yourself to a vendor is to use a sourcing firm. But this comes at a price. Minimally you’ll spend ~7 % or more to do your purchasing this way.
Here is some insight into the process. Specialty chemicals are frequently used in proprietary processes by a customer. There is an understanding that a vendor will not disclose the details of who inquired about what. Mainly, it is because the vendor does not want the competition to court the potential customer and take away the business. Another reason is that the customer regards secrecy as important because costs and volumes can be a giveaway to their competitors as to intimate details of their business. You just don’t blab about who wants what. It is a silo effect. It is quite difficult to find out who is buying what.
The secretive nature of bulk pricing means that a company is often poorly informed about the competitive pricing picture of its products. In order for a market to be rational on a short time frame, there needs to be prompt feedback, particularly on why a bid was not won. This seems obvious, but in practice, a sales group may be quoting many more bids than that can follow up on. It is easy to fall into the trap of being more busy chumming the waters with bait than hauling in the fish. A properly operating sales force is busy sending out quotes and doing follow up communications to see how the quote was received. This allows the sales people to adjust prices and terms on the fly. This is absolutely critical to maximizing sales. And a really good sales manager is one who insists on followup data to energize the feedback loop.
Bureaucratic Stem Cells
In some ways a company in it’s early years is like a stem cell. It has the capacity to grow into many types of organizations. At some critical juncture a signal comes along that points it one direction or another. It can grow into a free form organization like the legendary Silicon Valley startups where imagination is expected, there are free cokes in the fridge, and there are open spaces where employees can toss Nerf balls. On the other extreme are organizations that wear a more grim decorum. My experience has been that the petroleum and automotive industries are a little tighter in the puckerstrings. Companies evolve in response to their circumstances and in response to the people who run them.
As a company grows, it has to take on more people to manage the workload. But a bigger head count means more degrees of freedom; that is to say, there are more nodes in any given decision tree; more ways of doing things; more preferences to be managed. A bigger head count means that more failure modes are possible. More ways of having a disaster. More ways of having people problems.
In response to this, even the most well intended business founder must develop systems to contain and direct the energies of its people. Some people naturally pitch in and contribute to the good of the whole. Others specialize in gaming the system to their advantage. But the overall tone of any organization is set by the leaders. Some are old testament and others are new testament. Some require stonings and blood sacrifice and others use the redemption approach.
Business isn’t just an math exercise. There is a lot of anthropology to it. Unfortunately, anthropology isn’t on the curriculum of most MBA programs. MBA’s worry me. They seem to be hustling the rest of us into an Orwellian future with methodologies taught by faculty that may not have actually been business people.
Readers may doubt the merits of this conclusion. But, wait until you take a personality profile test to qualify for promotion or a job. The examiner will sit you down afterwards and tell you that the numbers say that your path has already been determined by this profile. What do you think the psychology graduates have been doing the last 30 years? Not all of them have been doing marriage counseling all this time. Many have been developing these test “instruments” for consultants and HR departments. It’s a scary world.
Watts and Watts of Ice
Many years ago I had the chance to visit the National Maritime Museum in London. It is a fantastic museum and if you’re ever in London, try to take a day to visit. The Royal Greenwich Observatory is nearby as well, so you can see the prime meridian and the transit telescope. I seem to recall that Christopher Wren was the architect of the Observatory. Anyway, I remember a visit to the cafeteria there and an observation that I made while buying lunch.
As an American in Europe, your presence is obvious to everyone. Well, to everyone but a few who may suspect you’re a Canadian. And a more awkward bunch of preening land lubbers you’ll never find than American tourists abroad. So, standing there at the food counter with fish & chips and waiting for my aliquot of Coca Cola, the matron behind the counter noted that I was an American and asked if I required ice. Yes indeed, says I. She nods and hobbles over to a small ice bucket, not unlike the kind you see in a motel room. She brings the bucket and using a pair of tongs, reaches in and fetches a single ice cube for my 300 mL portion of the blessed nectar.
At first I was struck with their miserly approach to dispensing ice. They didn’t invest in a commercial high output ice machine like even the most modest American mom & pop cafe had. But sitting there munching on my deep fried cod, I started to think about the vast resources Americans consume in order to have a ready supply of ice.
Just think of it. How many restaurants are there in the USA? According to Datanetwork there are 516,326 restaurants in their database for the USA. If you assume that each restaurant has 1 ice machine, and the ice machine draws, say, 12 amps at 120 VAC, and using the rms value for AC voltage (0.707 * 120 V = 84.84 Vrms) we can use Ohms law to calculate the wattage: power = EI = (84.84 Vrms * 12 Amps) = 1018 watts while in operation. Obviously, there are wide variations in parameters out there in the field. This is just a SWAG- Scientific Wild Assed Guess.
So, multiplying the number of restaurants times the wattage: 516,326 * 1018 watts = 525,619,868 watts, or ~ 526 megawatts of demand. Assuming that the power distribution losses in the grid are ~20 % (just a guess!), that means that the utilities have to generate 657 megawatts at the plant so that 526 megawatts get to the consumers. But it gets better.
The thermodynamic efficiency of a power plant is approximately 33 %, so 657 megawatts/0.33 = 1991 megawatts thermal have to be consumed to to generate the 657 megawatts electrical. Let’s assume a typical ice maching runs 25 % 0f the time, or 6 hrs per day: Energy consumption for one day is 1991 megawatts * 6 hours = 11,946 megawatt hrs thermal per day. So, lets get down to coal and oil consumption-
(11,946 MWHr * 3,412,000 BTU/MWHr) = 40.76 E9 BTU ==> (40.76E9 BTU/13,000 BTU per lb bituminous coal) = 3,135,000 lbs of bituminous coal per day, or 1568 tons per day, or 572,000 tons per year. The metric conversion is 1.1025 tons per metric ton. So, 572,000 tons/1.1025 = 518,821 metric tons per year. For conversion to equivalent barrels of crude oil, use 4.879 barrels equivalent crude oil per metric ton of coal. Thus, 518,821 MT coal * 4.879 bbl crude oil/MT of coal = 2.53 million barrels of oil per year to energize ice machines for our cokes and Slurpies.
So, 2.53 million barrels of oil * 60$/barrel= $151.8 million. A drop in the bucket in a $10 trillion economy. But it is just a tiny sliver of the whole spectrum of profligate uses of energy. What we need is to summon some sensibility and reduce our individual consumption of energy. Think of all of the devices the typical home now has that are always on- anything with a clock, DVD players and televisions that can be activated by remote, plug in cell phone chargers, etc.- all consume a trickle current.
So forgive me for asking the following question. If we are more than happy to commit the brightest minds in our country to find new energy souces, develop more potent weaponry, teach urban combat in our war colleges, invade savage and squalid middle eastern “countries”, resurrect the nuclear power industry, invent hybrid automobiles, etc., then why can’t we commit a small portion of that effort to reducing demand for resources whose scarcity can trigger a war?
Oh yea, reducing consumption means buying fewer goods and services. How do you reduce consumption while maintaining growth? There is the fly in the ointment.

Into the Bezosphere, Gradatim Ferociter
The founder of Amazon.com, Jeff Bezos, is certainly an enterprising fellow. He has started his own space program and is making actual progress. He bought 165,000 acres of Texas, started a company called Blue Origin, and has hired the best rocket and propulsion people he can find. The first space race began post-WWII, when there was a frenzied dash by the US and the Soviets to nab the best German rocket scientists their armies could round up. In the present commercial Space Race, Bezos and other billionaires can pick and choose their staff from the best and brightest space cadets that money can buy.
The link above contains some footage of the spacecraft lifting to a modest altitude and returning gently to the ground. It lifts off vertically and uses a powered reverse decent to touch down. The footage shows a launch where the exhaust gasses are not obviously incandescent and there is little or no “smoke”. This suggests to me that there is little in the way of carbonaceous components in the propellant. I wonder if it uses hydrogen peroxide as the propellant, like the famed jet packs use. Anyway, it’s all very hush-hush.
The slogan of the Bezonauts will be Gradatim Ferociter- step by step, fiercely.
Sign me up, boys. I’ll take a window seat.

Pomegranate Juice UV-Vis Spectrum

I’ve been really curious about the UV/Vis Spectrum of Pomegranate juice, so I finally broke down and ran the spectrum. I bought commercially available Odwalla Pomegranate Juice from Safeway and diluted 0.50 mL of this juice in 100 mL (+/- 1 mL) of distilled H2O. It is approximately 200 to 1 dilution. This commercial juice is also mixed with Chokecherry, Elderberry, Blueberry, Black Currant, and Apple juices, as well as a bit of citric acid. I’m going to try to get plain pomegranate juice for comparison.
I took a bit of the diluted soln and added some metals to it to see if there were any shifts in peak wavelength. The two shoulders (~250 and ~350 nm) were unchanged in wavelength and extinction, but the extinction of the peak at 193 nm was increased. The metals were SnCl2, ZnCl2, FeCl3, and MnOAc2. The Mn(II) Acetate has a fair extinction at ~195 nm but drops sharply at ca 200 nm. In all cases the shoulders remained. I would have to run a control to see if the consistent uptick in extinction at 193 nm is due to the metal ions.
When the dilute juice soln was treated with a few grains of NaIO4, the shoulders disappeared and the soln promptly took a clear yellow color. So it should be possible to follow the oxidative degradation of these solutions by UV/Vis. Since the juice is a complex mix of chromaphores, there is no telling what species are involved and what exactly is being oxidized. I’m sure that someone has sorted out what is in pomegranate juice.
This is what I did with a saturday afternoon.
Buy Side Sell Side
In the business world, most people will claim to appreciate the value of competition. Everybody understands how competition causes prices to trend downwards . And everybody has a basic grasp on the argument that monopoly domination of a market is ultimately stifling to innovation. But despite this understanding of the merits of competition, people still try to get as close to monopoly as they are allowed.
There are two sides to any business- the sell side and the buy side. The sell side hates competition and the buy side loves it. The sell side wants to eliminate competition and grab as much market share as it can. The buy side wants to promote competition to drive down the cost of raw materials and services. All businesses have this sort of left brain, right brain relationship with competition.
The sales folk know all too well the blinding power of competition. I remember many meetings where I have made heartfelt and sincere presentations to reassure a customer that our company is there for them , but regrettably the product we had been supplying for years was going to suffer a minor price increase. My Swiss Army knife of sales tools was wide open and all of the tools had gouge marks on them. The customer seemed pursuaded. But this was the calm before the storm.
At first, and with a hurt look on his face and an alligator tear running down his cheek, he’ll exclaim that it has come to his attention that there are two other vendors with substantially better pricing. Then, stiffening up noticeably, he’ll go on to say that apparently they had been paying far too much for far too long. Some procurement people will even accuse you of making them look bad in front of their management. Others will just shrug and sit there staring at you silently, waiting for you to hack up a price concession.
This is the point where the skilled sales person gives a performance worthy of Lawrence Olivier. You regain your composure and put on the most cheerful face you can. Here is where your collection of euphamisms comes in handy. My personal favorite- “Well, we’ll have to go back and sharpen our pencils and see what we can do. We’ll be in touch soon”. Did you get that? Sharpen our pencils? The really smooth purchasing people will use it first- “We think you need to sharpen your pencils on this pricing…”.
When a purchasing person says this to you, it is actually a gift. It is a graceful way of saying that you need to stop being stupid and requote a fair price. It is a gift because they haven’t disqualified you just yet. It is a last chance. Some purchasing people are very haughty and take high prices personally. When you ship a quote to them that was out of line, they won’t even bother to reply or try to negotiate. Like a fly, they just hop over to the next hot dung pile.
Better answers to better questions by the PITA
It is hard for a fellow to comprehend just how much of a pain-in-the-ass (PITA) he can be to everyone unless he’s been married for a while. One of the “benefits” of being married is the constant feedback you get. Heart-felt exclamations of wonderment: How could you not know that? What were you thinking? Why didn’t you _____ ? (fill in the blank) … The list has been truncated to save bandwidth.
Something that I have noticed over the last few years is the manner in which I answer questions. My natural inclination is to offer answers to questions that I wish had been asked. This is the professor in me and sometimes it is okay to do. But it does confound some people. It bears some resemblance to the sport of fencing. The question comes jabbing into your scoring zone so you parry and thrust into theirs. It seems a bit too competitive.
This competitive manner of conversation was polished to a high gloss in grad school. I was in a large research group (20-25) with post-docs and grad students from all over the world. To survive intellectually, you had to defend yourself and your ideas- sometimes very aggressively. A residue of this forcefulness survives to this day. The trick is to keep it sheathed when speaking with ones spouse.
