University of Nottingham scientists have been instrumental in helping to establish a pioneering branch of chemistry in Ethiopia.
They have helped to introduce Green Chemistry, an emerging field of sustainable science that will help African nations to meet the challenges of the 21st century.
Green Chemistry focuses on greener ways of creating chemicals, and is now regarded as one of the major routes to more environmentally-friendly production of the chemicals that underpin modern society.
In a "2007 Hot Article" of the journal Biochemistry, University at Buffalo chemists report the discovery of a central mechanism responsible for the action of the powerful biological catalysts known as enzymes.
The UB research provides critical insight into why catalysis is so complex and may help pave the way for improving the design of synthetic catalysts.
“The more that is known about catalysis, the better chances we have of designing active catalysts,” said John P. Richard, Ph.D., professor of chemistry in the UB College of Arts and Sciences and co-author of the paper with Tina L. Amyes, Ph.D., UB adjunct associate professor of chemistry.
Ultrafast intramolecular electronic charge separation during photo-chemical reactions cause up to tenthousand surrounding molecules to perform aligning pirouettes. Researchers observed for the first time such light induced reorientations in an organic molecular crystal.
In their study they initiated a separation of positive and negative electronic charge in a small number of particular molecules with extremely short light pulses. In turn the surrounding molecules responded by aligning their respective dipole axes along the photoinduced electric fields. The researchers observed this fundamental process for the first time by means of femtosecond x-ray diffraction with high spatial precision and in real time.
Sandia National Laboratories is pioneering the future of superalloy materials by advancing the science behind how those superalloys are made.
As part of Sandia’s nanoscale research, a group of experts specializing in inorganic synthesis and characterization, modeling, and radiation science have designed a radical system of experiments to study the science of creating metal and alloy nanoparticles.

Before life emerged on earth, either a primitive kind of metabolism or an RNA-like duplicating machinery must have set the stage – so experts believe. But what preceded these pre-life steps?
A pair of UCSF scientists has developed a model explaining how simple chemical and physical processes may have laid the foundation for life. Like all useful models, theirs can be tested, and they describe how this can be done. Their model is based on simple, well-known chemical and physical laws.
We met with the librarians today and Beth gave them movie screens that play on Second Life. I also got to put a few of my lectures from CHEM241
, introductory organic chemistry in the chemistry area
Since I already have a blog used for vodcasting
with files in m4v format, all I had to do is put links to those files in Second Life. The screen is placed between the quiz obelisks on the left and the UsefulChem
project on the right.
With a nod to one of nature's best surface chemists—an obscure desert beetle—polymer scientists at the National Institute of Standards and Technology (NIST) have devised a convenient way to construct test surfaces with a variable affinity for water, so that the same surface can range from superhydrophilic to superhydrophobic, and everything in between.
Based on a suggestion by Beth and a rapid implementation by Eloise, the terrain of Drexel Island on Second Life
is now shaped like the Drexel dragon mascot. That makes it pretty convenient to specify where things are located.
I started with the dragon's head to create a little section for the chemistry department, showing a picture of our building and adding some info as a note attached to the image.
When it comes to studying energy transfer in photosynthesis, it's good to think "outside the bun."
That's what Robert Blankenship, Ph.D., professor of biology and chemistry in Arts & Sciences at Washington University in St. Louis, did when he contributed a protein to a study performed by his collaborators at Lawrence Berkeley National Laboratory and the University of California at Berkeley. The protein's moniker? The taco shell protein.
Freeze-dried ice cream looks like the original product, and even tastes pretty good, but "drying" ice cream at room temperature would leave a sour-smelling, sloppy mess. Similarly, diamonds ejected from deep in the Earth can survive the journey intact only if they head toward the surface quickly and under just the right conditions.
Diamonds, found almost exclusively within kimberlite formations, are stable at great depth and at the planet's surface but rapidly turn to graphite under the high temperature/low pressure condi-tions of most eruptions.
