A battery’s hopping ions remember where they’ve been

Seen in atomic detail, the seemingly smooth flow of ions through a battery’s electrolyte is surprisingly complicated

22-Feb-2024 - Solid-state batteries store and release charge by nudging ions back and forth between two electrodes. From our usual point of view, the ions flow through the battery’s solid electrolyte like a gentle stream. But when seen on an atomic scale, that smooth flow is an illusion: Individual ions hop ...

Reversible Adhesive

Recycling of Water-Based Adhesive Achieved by Changing pH

15-Nov-2023 - A research team has developed a reversible, water-based glue that has good adhesion in the neutral pH range, but can be detached again in strongly acidic or alkaline environments. As the team writes in the journal Angewandte Chemie, the novel adhesive system, which is based on electrostatic ...

Chemistry breakthrough could speed up drug development

12-May-2020 - Scientists have successfully developed a new technique to reliably grow crystals of organic soluble molecules from nanoscale droplets, unlocking the potential of accelerated new drug development. Chemistry experts from Newcastle and Durham universities, working in collaboration with SPT Labtech, ...

New safety test predicts reactions to novel drugs and cosmetics

29-May-2013 - A simple lab-based skin test which eliminates the risk of adverse reactions to new drugs, cosmetics and household chemicals has been developed by a Newcastle University, UK team. It uses real human skin and immune cells to show any reaction such as a rash or blistering indicating a wider immune ...

Mannosidase catches the boat

15-Apr-2009 - A boat conformation of the Michaelis complex of beta-mannosidase Man2A has been demonstrated by a collaboration of scientists in the UK and Canada. Gideon Davies and Wendy Offen at the University of York and colleagues from Newcastle University, worked with scientists from Queen’s University, ...

From Enzymes to MOFs

17-Oct-2008 - UK scientists have used dioxygenase enzymes to create enantiopure organic molecules, which in turn have been used to create chiral metal-organic frameworks. Dioxygenase enzymes were sourced from modified bacterial whole cells (mutants), isolated from the environment. These were then used as ...

Dolomite's Microfluidics Technology Enables Nanoparticle Synthesis

06-May-2008 - Dolomite have announced that they have been working with Newcastle University as part of a project to explore the application of microfluidics for the synthesis of nanoparticles for use in biochemistry. Microfluidics, often called lab-on-a-chip, is a new field of science and engineering that ...

Technological breakthrough in the fight to cut greenhouse gases

28-Apr-2008 - Scientists at Newcastle University have pioneered breakthrough technology in the fight to cut greenhouse gases. The Newcastle University team, led by Michael North, Professor of Organic Chemistry, has developed a highly energy-efficient method of converting waste carbon dioxide (CO2) into ...
