ResearchNew example of molecular chirality discovered
The first instance of a molecule in which an oxygen atom is the sole stereocentre has been reported
-
ResearchNew theory provides answers to why metals have the structures that they do
The simple concept shows that a metal’s structure results from chemical interactions between localised electrons, challenging the traditional free electron gas model
-
ResearchMolecular motor running on electricity mimics biological motors
The nanomachine is based on a [3]catenane and isn’t operated through a microscope tip, unlike others
-
ResearchFully automated synthesis robot sets new record in stereospecific carbon–carbon bond formation
The robotic platform can make six carbon–carbon bonds without human guidance
-
ResearchMystery of speedy proton hopping in water unravelled
X-ray spectroscopy helps scientists understand how protons move in water
-
ResearchBenzene’s bond lengths corrected
Sophisticated spectroscopic method shows that previously reported values were out by several milliangstroms
-
NewsGerman firms raided over dual use chemicals sent to Russia
Companies have reportedly been exporting substances that could be turned into chemical weapons for several years without a permit
-
ResearchMultitasking boron catalyses first aldol reaction from esters
Using esters instead of aldehydes offers chemists a completely new retrosynthetic disconnection
-
ResearchClever carbene synthesis replaces notoriously hazardous chemistry
Reactive carbon compounds can now be made from aldehydes instead of explosive or unstable reagents
-
ResearchRich chemistry revealed by tip microscopy pulses’ bond making and breaking
Using an STM, scientists have been able to precisely switch between three different molecules, opening the way to multiple selective transformations
-
ResearchElectrocatalytic hydrogen atom transfer could give industrial organic synthesis a boost
The new approach – inspired by decades of energy storage research – is selective, efficient and sustainable
-
ResearchIt’s not enough to be 3D and aromatic to be 3D aromatic
Misusing the term 3D aromaticity could put chemists on a slippery slope where the concept loses meaning
-
ResearchCatalytic alchemy sees device transform one metal so that it behaves like another
Electric charge enables the catalytic ‘speed limit’ for many important reactions to be bypassed
-
ResearchLunar soil shows promise as a catalyst for extraterrestrial photosynthesis
Moon rock could one day be used to accelerate water splitting and carbon dioxide conversion in space to support crewed missions
-
ResearchAI tool finds green ways to turn chemical waste into drugs
Circular approach for industry by-products considers environmental, economic and geographic aspects to rank predicted routes for real-world applications
-
ResearchPepto-Bismol compound’s structure unveiled after 120 years
Electron microscopy triumphed over x-ray crystallography as century-old structural puzzle around bismuth subsalicylate is finally solved
-
ResearchSwitching molecular self-assembly on and off with electricity
New approach uses electrons to catalyse molecular recognition, giving chemists precise control over the process
-
ResearchCatalyst-free strategy allows Raft polymers to be unzipped for recycling
The approach exploits active end groups produced during the polymerisation process to regenerate the starting monomers in excellent yield
-
ResearchRobot chemist snaps 3D building blocks together like Lego to make complex molecules
Automated synthesiser uses a new class of boronates that are a thousand times more stable than those previously used
-
ResearchNew microscope makes tracking chiral molecules in live cells possible
The instrument uses circularly polarised light to tell left- and right-handed species apart and monitor them in space and time
