Water distribution in the fuel cell made visible in 4D

The analysis opens new possibilities for more efficient and thus more cost-effective fuel cells

09-Jun-2022

Teams from Helmholtz-Zentrum Berlin (HZB) and University College London (UCL) have visualised the water distribution in a fuel cell in three dimensions and in real time for the first time by evaluating neutron data from the Berlin Experimental Reactor shut down in 2019. The analysis opens new ...

Scientists can predict and design single atom catalysts for important chemical reactions

Using fundamental calculations of molecular interactions, they created a catalyst with 100% selectivity in producing propylene

28-Jun-2021

Researchers at Tufts University, University College London (UCL), Cambridge University and University of California at Santa Barbara have demonstrated that a catalyst can indeed be an agent of change. In a study published in Science, they used quantum chemical simulations run on supercomputers to ...

New material for longer-lasting fuel cells developed

New research suggests that graphene - made in a specific way - could be used to make more durable hydrogen fuel cells for cars

24-Jul-2020

In the study, published in the journal Nanoscale, scientists produced graphene via a special, scalable technique and used it to develop hydrogen fuel cell catalysts. The research team, involving scientists from Queen Mary University of London and University College London (UCL), showed that this ...

Fast-charging, long-running, bendy energy storage breakthrough

Imagine needing only ten minutes to fully-charge your electric car

20-Feb-2020

A new bendable supercapacitor made from graphene, which charges quickly and safely stores a record-high level of energy for use over a long period, has been developed and demonstrated by UCL and Chinese Academy of Sciences researchers. While at the proof-of-concept stage, it shows enormous ...

Using neutrons and X-rays to analyse the ageing of lithium batteries

11-Feb-2020

An international team has used neutron and X-ray tomography to investigate the dynamic processes that lead to capacity degradation at the electrodes in lithium batteries. Using a new mathematical method, it was possible to virtually unwind electrodes that had been wound into the form of a compact ...

Using corkscrew lasers to separate mirror molecules

Innovative approach could deepen insight into the mysterious handedness of life

13-Dec-2019

Many of the molecular building blocks of life have two versions that are mirror images of one another, known as enantiomers. Although seemingly identical, the two enantiomers can have completely different chemical behaviour – a fact that has major implications in our day-to-day lives. For ...

Wonder material: Individual 2D phosphorene nanoribbons made for the first time

12-Apr-2019

Tiny, individual, flexible ribbons of crystalline phosphorus have been made by UCL researchers in a world first, and they could revolutionise electronics and fast-charging battery technology. Since the isolation of 2-dimensional phosphorene, which is the phosphorus equivalent of graphene, in ...

What the Smell Can Tell

The degradation status of modern polymeric museum artifacts can be classified by their smell

08-Mar-2018

Breath analysis in disease diagnostics is a promising research field, and the advances in instrumentation allows the accurate detection of metabolites. But not only the health status of patients, but also the preservation status of museum artifacts could be monitored. Heritage science researchers ...

Probing exotic ices

12-Oct-2017

Water is everywhere. But it's not the same everywhere. When frozen under extreme pressures and temperatures, ice takes on a range of complex crystalline structures. Many of the properties and behaviors of these exotic ices remain mysterious, but a team of researchers recently provided new ...

Cloud Formation: How Feldspar Acts as Ice Nucleus

12-Dec-2016

In the atmosphere, feldspar particles act as ice nuclei that make ice crystals grow in clouds and enable precipitation. The reason was found by researchers of Karlsruhe Institute of Technology (KIT) and University College London (UCL) with the help of electron microscopy observations and ...
