Chemist Wendy Shaw, a nationally recognized scientific leader, has been chosen to serve as the associate laboratory director for PNNL's Physical and Computational Sciences Directorate.
Researchers have uncovered new insights into electrochemical CO2 reduction, a process by which energy from the sun can be used to convert carbon dioxide into liquid fuels and other useful chemicals.
With more than 181.5 billion tons of wood produced globally each year, a new method could revolutionize how we build sustainably. By infusing red oak with ferrihydrite using a simple, low-cost process, researchers strengthened the wood at the cellular level without adding weight or altering flexibility – offering a durable, eco-friendly alternative to steel and concrete.
Researchers have developed a new therapy that can be injected intravenously right after a heart attack to promote healing and prevent heart failure. The therapy both prompts the immune system to encourage tissue repair and promotes survival of heart muscle cells after a heart attack.
In the corner of a lab room in Candelaria Hall is a handheld tool that looks similar to a barcode scanner grocery store clerks use at the checkout line.
As a high school student, Isaac Subuloye noticed many of his peers were intimidated by chemistry. Many of his teachers struggled to make chemistry interesting or present the topic in a way that was easily understood by students.
Building off previous research, a team publishing in ACS Food Science & Technology describes successfully using plant-based ingredients to mimic calamari that matches the real seafood’s characteristic softness and elasticity.
Los investigadores han informado en ACS Central Science que algunas de las resinas utilizadas para estos recubrimientos reaccionan con metales ferrosos y pueden causar da?os. El equipo creó una estrategia de imagen de fluorescencia no invasiva que revela las se?ales temprana de estas reacciones químicas perjudiciales, y confirmó su utilidad en piezas arqueológicas antiguas.
Imagine a smoke detector that instead of warning residents of smoke before a fire engulfs their home, is placed in mass-transit locations to alert travelers and first responders to hazardous chemicals in the air.
Researchers reporting in ACS’ Nano Letters took advantage of the tardigrade’s nearly indestructible nature and gave the critters tiny “tattoos” to test a microfabrication technique to build microscopic, biocompatible devices.
但是，研究人员在《中央科学》 (ACS Central Science) 期刊中报告称，这些涂层所用的某些树脂会与含铁金属发生反应并可能造成损害。该团队研发了一种非侵入性荧光成像技术，可以揭示这些具有破坏性的化学反应的早期迹象，并已在古代文物上验证了该技术的功用。
Conservators and museum technicians use clear coatings to protect archaeological metal objects, preserving their detailed views. However, some resins in these coatings react with iron-containing metals, causing damage.
If Quebecers are now aware of the health risks of per- and polyfluoroalkyl substances (PFAS), it’s largely thanks to the work of UdeM's muckraking environmental chemistry professor.

The pathogen that causes tuberculosis is deadly in part because of its complex outer envelope, which helps it evade immune responses of infected hosts. In an ACS Infectious Diseases paper, researchers developed a chemical probe to study a key component of this envelope. Their results provide a step toward finding new ways of inactivating the bacterium.
Researchers in ACS’ Environmental Science & Technology demonstrate that an artificial intelligence (AI)-based monitoring system combined with a computer model can link the exposure of neonicotinoid pesticides on individual honeybees to the health of the whole colony.
An international research collaboration led by Rutgers University-New Brunswick scientists that examined microscopic blobs of protein found in human cells has discovered that some morph from an almost honey-like substance to a hard candy-like solid. These mysterious droplets, known as biomolecular condensates, solidify when they carry a high proportion of the protein alpha-synuclein, the scientists reported in Science Advances. Clumps of alpha-synuclein are commonly found in the brain cells of people with Parkinson’s disease, a neurodegenerative brain disorder.
当两种材料接触时，其表面上的带电实体会受到轻微推动。这就是气球在皮肤上摩擦产生静电的原因。同样，流过某些????表面的水也会获得或失去电荷。现在，有研究人员在《ACS Central Science》期刊上发表文章称已经利用这种现象，根据流经管道的雨状液滴进行发电。他们展示了一种新型流动模式，其产生的功率足以??????点亮 12 个 LED。
Cuando dos materiales se tocan, sus cargas superficiales se alteran, generando electricidad estática. Investigadores han aprovechado este fenómeno para generar electricidad a partir de gotas de agua que se desplazan por un tubo, produciendo suficiente energía para encender 12 LED.
John C. Gordon, chair of the Chemistry Division at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, was elected to the Royal Society of Edinburgh (RSE), Scotland’s National Academy of science and letters, as an International Fellow.
Water flowing over some surfaces can gain or lose charge. Now, researchers reporting in ACS Central Science have harnessed the phenomenon to generate electricity from rain-like droplets moving through a tube. They demonstrate a new kind of flow that makes enough power to light 12 LEDs.
