A greener, more sustainable source of ingredients for widely used plastics

A new process can convert a wide variety of vegetable and animal fats and oils — ranging from lard to waste cooking oil — into a key ingredient for making plastics that currently comes from petroleum, scientists say. Their report on the first-of-its-kind process appears in the journal ACS Sustainable Chemistry & Engineering.

QR code access to Nobel Prizes in Chemistry

Mobile devices equipped with a QR (quick response) code scanning app, which gives consumers instant access to information on the Web, now can give the same access to 110 years of information about the most prestigious honors in science, the Nobel Prizes.

A new form of aspirin to overcome ‘aspirin resistance’

Scientists are reporting development of a new form of aspirin — taken daily by about 60 million people in the United States alone to reduce the risk of heart attack and stroke — that could extend aspirin’s benefits to people who may not respond to the drug. Their advance toward coping with “aspirin resistance” appears in the journal ACS Nano.

Almost 20 percent of grain in China lost or wasted from field to fork

A comprehensive new review of food waste in the People’s Republic of China has concluded that about 19 of every 100 pounds of grain produced in the country go to waste, with related losses of water for irrigation and farmland productivity. The report appears in ACS’ journal Environmental Science & Technology.

Remembering a famous debate 400 years ago and water’s still-unsolved mysteries

For online and print audiences deep into lazy late-summer-day reading, yearning for diversions from everyday cares, how about a glimpse 400 years back in time at a famous clash between Galileo and an arch-enemy over why ice floats on water? That debate, between a giant in the history of science and a little-remembered naysayer who challenged Galileo’s idea that Earth revolves around the sun, is the topic of a story in the current edition of Chemical & Engineering News. C&EN is the weekly newsmagazine of the American Chemical Society, the world’s largest scientific society.

Material in dissolvable sutures could treat brain infections, reducing hospital stays

A plastic material already used in absorbable surgical sutures and other medical devices shows promise for continuous administration of antibiotics to patients with brain infections, scientists are reporting in a new study. Use of the material, placed directly on the brain’s surface, could reduce the need for weeks of costly hospital stays now required for such treatment, they say in the journal ACS Chemical Neuroscience.

Producing hydrogen from water with carbon/charcoal powder

In the latest advance in efforts to find an inexpensive way to make hydrogen from ordinary water — one of the keys to the much-discussed “hydrogen economy” — scientists are reporting that powder from high-grade charcoal and other forms of carbon can free hydrogen from water illuminated with laser pulses. A report on the discovery appears in ACS’ Journal of Physical Chemistry C.

Butterfly wings + carbon nanotubes = new ‘nanobiocomposite’ material

Leveraging the amazing natural properties of the Morpho butterfly's wings, scientists have developed a nanobiocomposite material that shows promise for wearable electronic devices, highly sensitive light sensors and sustainable batteries. A report on the new hybrid material appears in the journal ACS Nano.

Using a form of ‘ice that burns’ to make potable water from oil and gas production

In the midst of an intensifying global water crisis, scientists are reporting development of a more economical way to use one form of the “ice that burns” to turn very salty wastewater from fracking and other oil and gas production methods into water for drinking and irrigation. The study on the method, which removes more than 90 percent of the salt, appears in the journal ACS Sustainable Chemistry & Engineering.

What to do if your dog gets ‘skunked’ wins American Chemical Society video contest

WASHINGTON, A lesson on what to do if your dog gets “skunked” has won a video contest sponsored by the American Chemical Society (ACS), the world’s largest scientific society, to showcase the uses of chemistry in everyday life, and celebrate the 90th anniversary of its weekly newsmagazine, Chemical & Engineering News (C&EN).

First update in a century in testing drugs for elemental impurities

For the first time in more than 100 years, drug and dietary supplement manufacturers are updating the tests used to ensure that their products contain safe levels of metal impurities, and the stringent new requirements, instruments and costs are the topic of the cover story in the current edition of Chemical & Engineering News. C&EN is the weekly newsmagazine of the American Chemical Society, the world’s largest scientific society.

Insect-inspired super rubber moves toward practical uses in medicine

The remarkable, rubber-like protein that enables dragonflies, grasshoppers and other insects to flap their wings, jump and chirp has major potential uses in medicine, scientists conclude in an article in the journal ACS Macro Letters. It evaluates the latest advances toward using a protein called resilin in nanosprings, biorubbers, biosensors and other applications.

Home cooking, traffic are sources of key air pollutants from China

Almost 80 percent of air pollution involving soot that spreads from China over large areas of East Asia — impacting human health and fostering global warming — comes from city traffic and other forms of fossil-fuel combustion, such as home cooking with coal briquettes. That’s the conclusion of a study in ACS’ journal Environmental Science & Technology, which resolves long-standing questions about sources of air pollution responsible for Asia’s infamous atmospheric brown clouds.

New tests for determining health and environmental effects of nanomaterials

A group of international experts from government, industry and academia have concluded that alternative testing strategies (ATSs) that don’t rely on animals will be needed to cope with the wave of new nanomaterials emerging from the boom in nanoscience and nanotechnology. Their consensus statement from a workshop on the topic appears in the journal ACS Nano.

First scientific method to authenticate world’s costliest coffee

The world’s most expensive coffee can cost $80 a cup, and scientists now are reporting development of the first way to verify authenticity of this crème de la crème, the beans of which come from the feces of a Southeast Asian animal called a palm civet. Their study appears in ACS’ Journal of Agricultural and Food Chemistry.

The chemistry behind lobster color and shell disease

WASHINGTON, — With lobster shell disease moving up the East Coast toward Maine — now observing Maine Lobster Month — a new video from the world’s largest scientific society focuses on the disease, the chemistry of lobster shell color and why lobster shells turn red during cooking. The American Chemical Society (ACS) video, the latest episode in ACS’ award-winning Bytesize Science series, is at www.BytesizeScience.com.

A new sense of urgency for energy cane and other energy crops

“Energy cane” may sound like a trendy sports drink, but it actually is among a new generation of energy crops that could yield up to 5 times more ethanol per acre than corn. They are the topic of the cover story in this week’s Chemical & Engineering News. C&EN is the weekly newsmagazine of the American Chemical Society, the world’s largest scientific society.

Watermelon juice relieves post-exercise muscle soreness

Watermelon juice’s reputation among athletes is getting scientific support in a new study, which found that juice from the summer favorite fruit can relieve post-exercise muscle soreness.
