Novel chemical design makes hard crystals stretchy

Researchers hope to use chemical structure to target and trap impurities in water

09-Dec-2021 - Researchers have discovered a new way to make crystals stretchy, a modification that could enable them to act as very effective nanofilters. "Picture a diamond that behaves like a rubber band," says Assistant Professor of Chemistry Chenfeng Ke. His research team has designed a new type of porous, ...

Google provides open source library for quantum chemistry

Platform-independent solution to integrate future developments

26-Oct-2017 - Since physicists have been dealing with the theoretical description of molecules, the solving of quantum mechanical equations has been a major obstacle. This is supposed to be a thing of the past with the release of an open source based system. Google has introduced such a system to the public ...

New-generation material removes iodine from water

09-Jun-2017 - Researchers at Dartmouth College have developed a new material that scrubs iodine from water for the first time. The breakthrough could hold the key to cleaning radioactive waste in nuclear reactors and after nuclear accidents like the 2011 Fukushima disaster. The new-generation microporous ...

3-D printing turns nanomachines into life-size workers

24-Mar-2017 - Using advanced 3-D printing, Dartmouth College researchers have unlocked the key to transforming microscopic nanorings into smart materials that perform work at human-scale. Nanomachines can already deliver medication and serve as computer memories at the tiny nanometer scale. By integrating a ...

Team creates new method to control quantum systems

24-May-2016 - Dartmouth College researchers have discovered a method to design faster pulses, offering a new way to accurately control quantum systems. Quantum physics defines the rules that govern the realm of the ultra-small - the atomic and sub-atomic world -- which explains the behavior of matter and its ...

Mercury in fish affected by both prey type and quality

10-May-2016 - Whether fish hunt nearshore or in the open water and what prey they eat affect the amount of mercury that accumulates in them, a Dartmouth College study shows. Mercury accumulation in fish poses well-known health risks to humans and wildlife, but fish mercury levels are highly variable and key ...

Team devises new technique to probe 'noise' in quantum computing

20-Apr-2016 - Dartmouth College and Griffith University researchers have devised a new way to "sense" and control external noise in quantum computing. Quantum computing may revolutionize information processing by providing a means to solve problems too complex for traditional computers, with applications in ...

Fracking plays active role in generating toxic metal wastewater

17-Dec-2015 - The production of hazardous wastewater in hydraulic fracturing is assumed to be partly due to chemicals introduced into injected freshwater when it mixes with highly saline brine naturally present in the rock. But a Dartmouth study investigating the toxic metal barium in fracking wastewater finds ...

New research sheds light on mercury pollution in estuaries, food chain

09-Dec-2015 - Two studies by Dartmouth researchers and their colleagues shed new light on mercury pollution in the waters of the northeastern United States. Mercury, which is transformed into methylmercury in water, is a global pollutant that damages human health. Most people are exposed to mercury by eating ...

Molecular switch that changes liquid crystal colors

Nanotechnology tool may help in in detecting harmful gases, pathogens, explosives

28-Aug-2013 - Dartmouth researchers have developed a molecular switch that changes a liquid crystal's readout color based on a chemical input. This new development may open the way for using liquid crystals in detecting harmful gases, pathogens, explosives and other chemical substances. The findings appear in ...
