Which of the following processes would not result in an increase in entropy? (a) the melting of an ice cube (b) the sublimation of a moth ball (c) the evaporation of a puddle of gasoline (d) a glass of cool lemonad...
Future advancements in understanding and controlling RNA functions will hinge on new strategies capable of precisely modulating Cas13b/dCas13b activities while minimizing interference with inherent RNA processes. We have engineered a split Cas13b system that is conditionally activated and deactivated by ...

Ensuring the industrial applicability of molecular photocatalysis requires addressing the instability challenges experienced by catalysts during light-driven reactions. The frequent utilization of noble metal-based catalytic centers (such as.) is a widely recognized fact. The processes of particle formation ...
IL-21 within B cells orchestrates their proliferation, maturation into plasma cells, and the subsequent processes of class switching and antigen-specific antibody production. These traits establish IL-21 as a major player in a variety of immunological diseases, specifically rheumatoid arthritis and ...
Crystal size distribution in Jurassic Ferrar flows and sills (Victoria Land, Antarctica): evidence for processes of cooling, nucleation, and crystallisation Jurassic Ferrar rocks in Victoria Land (Antarctica) occur predominantly as basaltic or andesitic flows and sills. Both show characteristic petrographi...
This invention relates to a novel process for the manufacture of olefine oxides which comprises reacting an olefine with free oxygen, which oxygen may be present as oxygen per se or in admixture with other gaseous materials as steam, nitrogen, carbon dioxide, etc., said oxidation being effected...
However, there were drawbacks to the use of metal oxides; for example, the reaction was difficult to control and there was a risk that side reactions would occur. Moreover, the use of metal oxides made it necessary to carry out a post-reaction treatment in order to prevent adverse effects...
