Controlling regioselectivity remains one of the major challenges in hydrocyanation. When an unsymmetrical alkyne undergoes ...

Acid−base switchable supramolecular dendronized polyacetylenes (DPAs) with increasing steric bulk on going from generation one [G1] to three [G3], were constructed using multiple self-assembly ...

On December 2, 2022, the world marked the 80th anniversary of a groundbreaking scientific achievement: the first controlled nuclear chain reaction. This historic event took place at the University ...

A novel two-stage reaction-control scheme with a background-cancelling circuit—for reducing data volume and analysis time of an ion-sensitive-FET (ISFET)-based DNA sequencer—is proposed. The scheme ...

The results of glucose isomerization using Brønsted-base PEGDA-DMAPMA hydrogel catalysts reveal a 45% glucose conversion rate and a 27% fructose yield, with a 61% selectivity at 110 °C, within a 2 h ...

Hydrophobic Layer and Strong Electric Fields Their results emphasize the importance of two major mechanisms—the influence of large local electric fields and the effect of local hydrophobicity—that ...

Scientists discovered how to use an external electric field to control and accelerate a chemical reaction, like a 'switch'. This work could have a considerable impact on the development of new ...

Peptide nucleic acids progress for gene editing and antisense drugs These lab-made molecules can bind to genes more strongly than DNA and RNA do, making them promising drug candidates and genetic ...

The proteins that make up life on earth are synthesized on ribosomes and exclusively composed of L- or left-handed amino acids. A primordial RNA minihelix shows preference for L-amino acid over D ...
