An acid base reaction can involve the acceptance and donation of an electron pair based on the Lewis model. A Lewis acid accepts an electron pair from a Lewis base. The resulting product is known as the adduct. The bo...
The theoretical background of OB relies on orbital expansion effects that reveal the chemical bonding nature between a Lewis acid-base pair. Generally, the oxygen behaves as Lewis’s base, whilst the metal ions as Lewis’s acids. The concept of OB pertains to the reactivity of oxygen atoms ...

A Zr-Al-Beta zeolite with open Zr(IV) sites: an efficient bifunctional Lewis–Brnsted acid catalyst for a cascade reaction Herein, a Zr-Al-Beta zeolite was successfully prepared via a one-step strategy, that is, direct grafting of Zr species on commercial Al-Beta in ethanol. The presence...
1b)39,40. We found that 44.1% of the 12,339 BRD4-enriched enhancers had at least 1-base pair overlap with active enhancers in normal tissues and this number increases to 73.6% when compared to active enhancers across several cancer types. Of particular interest, we also identified ~6000 ...
This study reviews recent advancements in food science and technology, analyzing their impact on the development of intelligent food packaging within the c
Finally, we comprehensively describe the recent attempts to develop a broad-spectrum vaccine formulation that can neutralize the existing variants of SARS-CoV-2. 2. Methods In this review, the PubMed database was used to search and analyze the reported publications pertinent to the present review...
The initial chemisorption step is a Lewis acid/base interaction, where the oxygen lone pair of the target molecule is attracted to the unsaturated metal site. For this reason it can be speculated that the reactivity of the system must partly rely on the availability and strength of the Lewis ...
Furthermore, the segment of PAP that binds U1A is also involved in the coupling between splicing of the most 3′-terminal exon and the cleavage and polyadenylation reaction that is observed in mammalian cells and extracts (25, 26, 15). Since direct PAP–U1A interaction is unlikely to be ...
Oxidation-reduction and acid–base reactions are essential for the maintenance of all living organisms. However, redox potential (Eh) has received little attention in agronomy, unlike pH, which is regarded as a master variable. Agronomists are probably depriving themselves of a key factor in crop...
