Better sweat collection method could improve biomarker analysis
The chemical composition of human sweat tells us a lot about our health, but collecting it for analysis can be tricky. Current devices worn on the skin fill reservoirs one at a time but do not reflect how our rate of sweating changes throughout the d.....»»
Capturing the chemistry of radium-223 for cancer treatment
Scientists need a better understanding of the chemistry of radium to be able to target the isotope radium-223 (Ra-223) to cancer cells. Once delivered, Ra-223 can destroy those cells with alpha particles, a type of radiation......»»
The room-temperature superconductor that wasn’t
We have good explanations for why a chemical called LK-99 behaved the way it did. Enlarge / Levitation like this will apparently continue to require extremely cold temperatures for now. (credit: ClaudeLux) The summer of.....»»

Chemical engineers draft a roadmap for research into metallic "sponges" for clean hydrogen
Metal organic frameworks (MOFs) could deliver a major efficiency boost to the photocatalytic production of clean hydrogen. Chemical engineers have drafted a comprehensive overview of the state of their field and a plan for where it needs to focus......»»
Striking gold with molecular mystery solution for potential clean energy
Hydrogen spillover is exactly what it sounds like. Small metal nanoparticles anchored on a thermally stable oxide, like silica, comprise a major class of catalysts, which are substances used to accelerate chemical reactions without being consumed the.....»»
Newly discovered fungus helps destroy a harmful food toxin
Patulin (C7H6O4), a mycotoxin produced by several types of fungi, is toxic to a variety of life forms, including humans, mammals, plants, and microorganisms. In particular, environments lacking proper hygienic measures during food production are susc.....»»
Organic nanosensors may be able to detect harmful pesticides thanks to new research
Researchers at Concordia have developed a new system using tiny nanosensors called carbon dots to detect the presence of the widely used chemical glyphosate. Their research, titled "Ratiometric Sensing of Glyphosate in Water Using Dual Fluorescent Ca.....»»
Surpassing the human eye: Machine learning image analysis rapidly determines chemical mixture composition
Have you ever accidentally ruined a recipe in the kitchen by adding salt instead of sugar? Due to their similar appearance, it's an easy mistake to make. Similarly, checking with the naked eye is also used in chemistry labs to provide quick, initial.....»»
Semiconductor photocatalyst helps to realize borylation reaction
A research group led by Prof. Dai Wen from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has realized borylation reactions involving N-heterocyclic carbene boranes (NHC-BH3) with a simple and efficient heter.....»»
Turtles Carry Signs of Humanity’s Nuclear History in Their Shells
Turtles’ shells contain a chemical record of the environment—including highly enriched uranium, an indicator of nuclear weapons development. What can we learn from these accidental archivists?.....»»
Researchers produce polymers from ballbot-type carbenes for the first time
N-heterocyclic carbenes (NHCs) are small, reactive ring molecules that bond well with metallic surfaces, and which over the past few years have attracted a great deal of interest in the field of the stable chemical modification of metallic surfaces......»»
Study: Social justice for traditional knowledge holders will help conserve Europe"s nature
It is well known that biodiversity of cultural landscapes is threatened by land abandonment and agricultural intensification. Traditional, low chemical and machinery input management systems have long been acknowledged for their diverse benefits to m.....»»
Scientists use quantum device to slow down simulated chemical reaction 100 billion times
Scientists at the University of Sydney have, for the first time, used a quantum computer to engineer and directly observe a process critical in chemical reactions by slowing it down by a factor of 100 billion times......»»
Division of labor found to affect the risk of infection in clonal ant colonies
In a new study in Nature Communications, an international research team including scientists at the Max Planck Institute for Chemical Ecology reports that, given the same genetic makeup, individual behavior alone determines whether or not an individu.....»»
Producing carboxylic acids using an environmentally friendly technique
Polyamides are present in many different products, such as ropes for mountaineering, parachutes of nylon, and materials for 3D printing. Dicarboxylic acids are used as chemical building blocks for these polyamides. However, their production has been.....»»
New experimental research measures the speed of molecular charge migration for the first time
To discover how light interacts with molecules, the first step is to follow electron dynamics, which evolve at the attosecond timescale. The dynamics of this first step have been called charge migration (CM). CM plays a fundamental role in chemical r.....»»
