A nanostructured sensor, whose development and tests involved Skoltech researchers, has shown promise for enhancing construction parts made of glass fiber-reinforced polymer composite materials: aircraft wings, wind turbine blades, bridge spans, car.....»»
Printing atom by atom: Lab explores nanoscale 3D printing
It takes chemist Liaisan Khasanova less than a minute to turn an ordinary silica glass tube into a printing nozzle for a very special 3D printer. The chemist inserts the capillary tube—which is just one millimeter thick—into a blue device, closes.....»»
Enzymatic synthesis of primary, secondary and tertiary amines containing two stereocenters
In a paper just published in ACS Catalysis, the Biocatalysis research group at the University of Amsterdam's Van 't Hoff Institute for Molecular Synthesis presents a versatile method for the synthesis of primary, secondary, and tertiary amines contai.....»»
Enzymatic reactions: Researchers reveal a regulatory mechanism by which life controls and organizes itself
Inside cells, molecular droplets form defined compartments for chemical reactions. Not only sticky interactions between molecules, but also dynamic reactions can form such droplets, as was found by researchers from the Max Planck Institute for Dynami.....»»
Utilizing chemo-mechanical oscillations to mimic protocell behavior in manufactured microcapsules
The complexity of life on Earth was derived from simplicity: From the first protocells to the growth of any organism, individual cells aggregate into basic clumps and then form more complex structures. The earliest cells lacked complicated biochemica.....»»
Exploring the limits of a new kind of chemo
Chemotherapy sucks. The treatments generally have awful side effects, and it's no secret that the drugs involved are often toxic to the patient as well as their cancer. The idea is that, since cancers grow so quickly, chemotherapy will kill off the d.....»»
Changing the perspective on the origin of enzymatic catalytic power
The enzymes found in living organisms have impressive catalytic power. Thanks to enzymes, the chemical reactions that sustain life happen millions of times faster than they would occur without them. Enzymes speed up reactions by helping to lower the.....»»
