DFT‐assisted rational design of salan ligands for highly enantioselective Zr–salan‐catalyzed hydroxylation of cyclic β‐keto esters

open access: yesSmart Molecules, EarlyView.
Guided by DFT calculations, the design of novel C1‐symmetric salan ligands without the involvement of Suzuki coupling was achieved, and the preparation of α‐hydroxy‐β‐ketoesters in 99% yield and 99% ee was realized under low catalyst loading. Abstract In this work, a structurally simple, inexpensive, and readily accessible Zr–salan catalytic system was

Unlocking Neutral Hydrogen Evolution via a Lattice‐Proton‐Mediated Pathway on a Pt/h‐WO3 Single‐Atom Catalyst

open access: yesSusMat, EarlyView.
Efficient hydrogen evolution reaction (HER) in neutral media is hindered by sluggish water dissociation kinetics. Here, Pt single atoms coupled with a hexagonal tungsten oxide (h‐WO3) support enable a lattice‐proton‐mediated pathway, in which the HxWO3 lattice stores protons derived from water and Pt sites facilitate their utilization for H2 evolution.

Cyanogenic Compounds, Physicochemical Parameters and Metals in Water From Cassava Processing Areas: A Study in the Brazilian Amazon, Using Multivariate Analysis

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study evaluated the water quality of artesian wells and effluents generated in cassava processing in a rural area of Bragança, Pará, with emphasis on physicochemical parameters, multielement composition, and cyanogenic compounds. The well water presented specific nonconformities, highlighting pH values below the recommended level and high

Deciphering diverse cell‐death patterns to predict the prognosis and potential therapy target of hepatocellular carcinoma patients

open access: yesVIEW, EarlyView.
Abstract Ninety percent of all primary liver malignancies are hepatocellular carcinomas (HCC), making liver cancer the third most common cause of cancer‐associated mortality. Different patterns of programmed cell death (PCD) are crucial for the survival of tumors, and they might serve as a prognostic marker for HCC.
