Hydrothermal synthesis of chiral carbon dots
(John Wiley & Sons, Inc., 2022-12)
Nanocolloids that are cumulatively referred to as nanocarbons, attracted significant attention during the last decade because of facile synthesis methods, water solubility, tunable photoluminescence, easy surface modification, ...
Photochemical C(sp2)−H Pyridination via Arene–Pyridinium Electron Donor–Acceptor Complexes
(Wiley Periodicals, Inc., 2022-11-14)
This report describes the development of a photochemical method for C(sp2)−H pyridination that leverages the photoexcitation of electron donor–acceptor (EDA) complexes. Experimental and DFT studies show that black light ...
Manning condensation in ion exchange membranes: A review on ion partitioning and diffusion models
(John Wiley & Sons, Inc., 2022-11-01)
The rational design of ion exchange membranes (IEMs) is becoming more pertinent as their usage becomes broader and as their staple applications (i.e., electrodialysis, flow batteries, and fuel cells) improve in commercial ...
Ultrafast X-ray Absorption Spectroscopy Reveals Excited State Dynamics of B12 Coenzymes Controlled by the Axial Base
(American Chemical Society, 2023-11-23)
Polarized time-resolved X-ray absorption spectroscopy at the Co K-edge is used to probe the excited state dynamics and photolysis of base-off methylcobalamin and the excited state structure of base-off adenosylcobalamin. ...
Binary Mixtures in Linear Convection Arrays
(Wiley Periodicals, Inc.(Springer Netherlands, 2023-01-03)
We numerically investigated the dynamics of a mixture of finite-size active and passive disks in a linear array of two-dimensional convection rolls. The interplay of advection and steric interactions produces a number of ...
Identification of regulatory variants of carboxylesterase 1 (CES1): A proof-of-concept study for the application of the Allele-Specific Protein Expression (ASPE) assay in identifying cis-acting regulatory genetic polymorphisms
(Wiley Periodicals, Inc., 2023-01)
It is challenging to study regulatory genetic variants as gene expression is affected by both genetic polymorphisms and non-genetic regulators. The mRNA allele-specific expression (ASE) assay has been increasingly used for ...
A Bidentate Ligand Featuring Ditopic Lewis Acids in the Second Sphere for Selective Substrate Capture and Activation
(Wiley Periodicals, Inc., 2023-03-20)
We present a ligand platform featuring appended ditopic Lewis acids to facilitate capture/activation of diatomic substrates. We show that incorporation of two 9-borabicyclo[3.3.1]nonane (9-BBN) units on a single carbon ...
Preparation and Functionalization of Mono- and Polyfluoroepoxides via Fluoroalkylation of Carbonyl Electrophiles
(Wiley, 2023-02-16)
We outline a new synthetic method to prepare mono- and polyfluoroepoxides from a diverse pool of electrophiles (ketones, acyl chlorides, esters) and fluoroalkyl anion equivalents. The initially formed α-fluoro alkoxides ...
Super-Strong Hydrogel Composites Reinforced with PBO Nanofibers for Cartilage Replacement
(Wiley Periodicals, Inc.Imperial College Press, 2023-02)
Cartilage replacement materials exhibiting a set of demanding properties such as high water content, high mechanical stiffness, low friction, and excellent biocompatibility are quite difficult to achieve. Here, ...
