Meet the smallest fully integrated fuel cell in the world: only 9 mm3 in volume but 254 W per Liter in energy density. This millitechnology power source is the invention of  S. Moghaddam, PhD and his team [1]. A chemical reactor is used to produce hydrogen by reacting a metal hydride with water vapor.


 


The metal hydride chosen is lithium aluminum hydride, LiAlH ,which reacts with water to release hydrogen by the following equation:

 A new book, "Poisoned Profits: The Toxic Assault on Our Children" by Philip and Alice Shabecoff is praised for its competent journalism in January 5, 2009 issue of Chemical and Engineering News. The review article, Protecting Children From Toxic Chemicals,  transmits the book's message that toxic chemicals and heavy metals in the environment are responsible for much of the increase in chronic disease and disability in children.[1]

Clichés are soft.. they leave it to your imagination. 

Clichés are hard.. they leave it to your imagination.

Embedded in the clichés are stereotypes.





A new cliché: "2009 is years-old."

P.S. A Happy 2009 to ALL with peace and love.

Since 1899, when acetylsalicylic acid was named "aspirin" in Germany, the emphasis has been placed on its properties. There is a new wind on the subject -- a medical cyclone seems to be brewing in the United Kingdom. John R. Patterson and colleagues report their new findings in the Dec. 24 issue of ACS' biweekly Journal of Agricultural and Food Chemistry.

People can make their own salicylic acid (SA), the principal metabolite of aspirin. SA that gives aspirin its famous action on pain, fever, and inflammation is now looking like a star in its own "class" of bioregulators.

Tangerine skies.. Tangerine blossoms, so I thought while wearing my tangerine trench coat in the Netherlands. I had no idea how much the Dutch would be attracted to me ... for my coat. I learned soon that they favor 'that color' because of the Orange Family. My face lit up with "but you don't even have orange groves here."


 


The Prince of Orange, Prins van Oranje in Dutch, is scheduled to become the king of Holland on 30 April 2009. He is supposed to be an expert in Climate Change. His biography brings up Willem-Alexander Claus George Ferdinand's interest in international water management issues. That is perhaps a comfort to royalists everywhere but just a Prince Scientist to others.

Beware: green chemistry is soon to serve you green wines. And in boxes, too.

Once I read in Chemical and Engineering News a list of the chemicals in either red or white wines. I remember thinking "generic wines" to start with: Let's see the difference in the young and the old wines!

Chose my chemistry picks
Knew it was coming.
Let's see Science's tricks
Got the list humming?



1. Cellular reprogramming
2. Exoplanets
3. Cancer genes
4. High temperature superconducting materials
5. Proteins' work
6. Excess renewable energy storage
7. Embryo video
8. Good fat to fight
9. World weight calculation
10. Genome sequencing



ScientificBlogging.com has been plugging
Quite well, on plotting
Except one, World's Weight*
Who knew "that" quantum(ing)!

L. Frank Baum wrote "The Wizard of Oz" in 1900. As a centennial-celebration of this hugely popular American story, I went back to a reread. There are many themes to be explored in the land of Oz created by Baum. Starting with "Oz," you knew it stood for ounce, ounces of silver, contrary to others saying the tabs of O to Z in file folders, right?

The author was into supporting the silver platform in contemporary US politics. In 1960, S. J. Sackett wrote "Utopia of Oz", The Georgian Review, Vol XIV, pp 275-290. Here, staying with politics, are the political elements that I culled from this article. My assessment of these fifteen positions in 2008 is given as grades in progress since 1900.

Chemistry is wonderful. Chemistry now has to play more than ever an interdisciplinary role for new visions. Here are two wonderful studies that I caught singing to me in 2008. Both contain elegant science that promises sheer greatness. Each rocks in a different manner by means of chemistry.



The first one is in polymer chemistry, a dear interest of mine, for molecules that can rotate and slide. The second, an Inventors Hall of Fame winner, solves living-cell networks to cure the sick.

Dinosound revival is no kidding to me. I was at the foothills of tall snow-capped mountains by the sea when this happened. A very loud sound filled the meadows and startled my senses like a dinosaur call! Well, it happened again, the next day about the same time, just before the sunset and for several minutes. I had to inquire swiftly for a local answer.



Come on, did you just accept that we know the sounds of an animal that lived long before even a woman was on the world scene? I mean, did the dinosaurs bark or tweet, scream, hiss, roar, coo, neigh or sing?

"Ted" calls his name
Service is his fame
Turner turned World News
Into a 24-7 game!



As the world turns
So Ted's passion burns
Humanity loves him such
His charity widely churns.



Ted must love hilarity
Color B&W to clarity
Why to fuss here
Over a man o'Rarity?



In fields of snow
Ted's buffalo herds know
Free to roam large
While praising Turner's bow.



Since first, Fine Scientist
Said Ted's the greatest
"Man with a heart"
Helped humanity the Bravest.



Seventy is a perfection
Arrives at Ted's station
2008's only a warm-up
For 150's in transaction.



Look people, in deed

You might say I am fond of Sweden and its Nobel Prizes. Now that the Mars500 shortlist includes also a Swede, there implies another delight: The Swedish Biogas might save the day for men and women in space missions.

Biogas for Mars?  Biogas is simply a biofuel that is obtained when organic matter is decomposed biologically in the absence of oxygen. A typical biogas has the following composition in percentages:

Methane:  50-75
Carbon Dioxide:  25-50
Nitrogen:  0-10
Hydogen Sulfide:  0-3
Oxygen:  0-2
Hydrogen:  0-1

Record-breaking accomplishments confuse people about durability. In facing the frailty of humans and their machines, a 'sea of safety' is a comforting notion. Failures remind us safety can be improved. Take the Phoenix Mars Lander, our machine to touch water on another planet. Its operations came to an end on recent days in the arctic plains when sunlight became insufficient. The machine simply stopped working outside its operating parameters.

Two observations are remarkable today about the ozone-hole measurements. Both have been in the books for a while. First, the peak size in 2008 is larger than the one in 2007. Second, NOAA is getting ready for a new environmental satellite. I will also make a prediction for the next year.

Shrinkage is a good thing when you want it to happen. Energy consumption in buildings is a great candidate for shrinkage.  Do you have a building in mind?

Two reports (1-2) were published recently to show how to achieve 50% energy savings over the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) Standard 90.1-2004 in medium-sized retail buildings and grocery stores. They represent the first technical support documents for commercial retail buildings under the U.S. Department of Energy's (DOE) Net-Zero Energy Commercial Building Initiative.

In all cases studied, these design measures were recommended to achieve a 50% reduction in energy consumption:

Letter* published in Nature Geoscience concluded at last: Overall, despite the paucity of observations, we find that human-induced warming is detectable in both these regions of high vulnerability to climate change.

Change happens. People can sense change but science can measure it and might be able to predict its future. A scientific model would be a beautiful help for us to understand the behavior of both the global economy and the Earth's climate. The International Energy Agency (IEA) has been developing the WEM-ECO model for that purpose.* This model is certainly a beauty resulting from the dreams of our humanity.

Consistent with their position that greenhouse gas emissions are causing global warming, the Royal Society (United Kingdom) is soliciting submissions to "moderate climate change by deliberate large-scale intervention in the working of the Earth's natural climate system." http://royalsociety.org/downloaddoc.asp?id=5845

Los Alamos* says we can make gasoline with CO2 extracted from air -- plus water and energy. Furthermore, economic large-scale production is possible with off-the-shelf equipment and known processes. Result: Green Gasoline.

The Los Alamos concept was named Green Freedom, mainly, because it promises freedom from foreign oil by producing gasoline with a carbon-neutral power source. The main steps are:

1. Obtain CO2 from the atmosphere

2. Split H2O into H2 and O2

3. Combine H2 and CO2 to produce methanol

4. Convert methanol into gasoline.
