Breaking ammonia: A new catalyst to generate hydrogen from ammonia at low temperatures

Producing Hydrogen from Ammonia Using State-Of-The-Art Calcium-Supported Nickel Catalyst

01-Sep-2021

The current global climate emergency and our rapidly receding energy resources have people looking out for cleaner alternatives like hydrogen fuel. When burnt in the presence of oxygen, hydrogen gas generates huge amounts of energy but none of the harmful greenhouse gases, unlike fossil fuels. ...

One “Ring” to Rule Them All

Curious Interlocked Molecules Show Dual Response

30-Jun-2021

Scientists at Tokyo Institute of Technology design polymers infused with a stress-sensitive molecular unit that respond to external forces by switching on their fluorescence. The researchers demonstrate the fluorescence to be dependent on the magnitude of force and show that it is possible to ...

Just Mix It Up

New Synthetic Method for Making Amphiphilic Molecules without Additives

29-Jun-2021

Amphiphilic molecules, which aggregate and encapsulate molecules in water, find use in several fields of chemistry. The simple, additive-free connection of hydrophilic and hydrophobic molecules would be an efficient method for amphiphilic molecule synthesis. However, such connections, or bonds, ...

Dethroning electrocatalysts for hydrogen production with inexpensive alternative material

Iron-based bimetallic electrocatalysts may be key for hydrogen synthesis

16-Mar-2021

Today, we can say without a shadow of doubt that an alternative to fossil fuels is needed. Fossil fuels are not only non-renewable sources of energy but also among the leading causes of global warming and air pollution. Thus, many scientists worldwide have their hopes placed on what they regard ...

A show of force: Novel polymer that toughens up and changes color upon mechanical stress

04-Feb-2021

A fascinating and crucial ability of biological tissue, such as muscle, is self-healing and self-strengthening in response to damage caused by external forces. Most human-made polymers, on the other hand, break irreversibly under enough mechanical stress, which makes them less useful for certain ...

Coiling them up: Synthesizing organic molecules with a long helical structure

Scientists explored the helical inversion process in the new, longer compounds

02-Feb-2021

Scientists at Tokyo Institute of Technology (Tokyo Tech) produced and extensively characterized novel organic molecules with a long helical structure. Unlike previous helical molecules, these longer compounds exhibit special interactions between coils that could give rise to interesting optical ...

New research shows how complex chemistry may be relevant to origins of life on Earth

09-Jun-2020

Chemists have long sought to understand the origins of life, with one popular model suggesting life began when simple RNA molecules capable of copying themselves formed spontaneously in the primitive environment. How this happened exactly is fraught with difficulties. New research by a team of ...
