Structures and growth pathways of AunCln+3- (n ≤ 7) cluster anions

Frontiers in Chemistry
Gold chloride clusters play an important role in catalysis and materials chemistry. Due to the diversity of their species and isomers, there is still a dearth of structural studies at the molecular level.

Whole-rotation dry matter and nitrogen grain yields from the first course of an organic farming crop rotation experiment

, 2002
The possibilities for increasing total grain yield in organic cereal production through manipulation of crop rotation design were investigated in a field experiment on different soil types in Denmark from 1997 to 2000.

Optical properties and bioavailability of dissolved organic matter along a flow-path continuum from soil pore waters to the Kolyma River mainstem, East Siberia [PDF]

, 2016
The Kolyma River in northeast Siberia is among the six largest Arctic rivers and drains a region underlain by vast deposits of Holocene-aged peat and Pleistocene-aged loess known as yedoma, most of which is currently stored in ice-rich permafrost ...

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

FEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Iron/phosphine-catalyzed reductive cross-coupling to construct quaternary carbon centers

Nature Communications
Transition metal-catalyzed C–C reductive coupling reactions avoid the direct use of sensitive metal reagents, representing a practical approach for constructing the skeletons of organic compounds.

Modeling the Self-Assembly of Organic Molecules in 2D Molecular Layers with Different Structures [PDF]

, 2016
If organic molecules are to be used as the active component in devices, self-assembly represents the most attractive route to control the geometric structure and therefore part of the device performance.

Quantitative proteomic analysis reveals different characteristics of bladder cancer cells after exposure to bisphenol A

FEBS Open Bio, EarlyView.
Bisphenol A (BPA), a common chemical in plastics, exerts dual effects on bladder cancer cells: low doses promote growth and migration, while high doses suppress growth and migration. Multi‐omics and bioinformatics reveal BPA acts via MAPK and inflammatory pathways.

Structural properties and charge distribution in graphene/BN heterostructures

Results in Surfaces and Interfaces
We investigate the structural properties of heterostructures comprising bilayer graphene covered with hexagonal boron nitride (hBN) using density functional theory including non-local van der Waals corrections.

Combined 5‐aminolevulinic acid and ferric ammonium citrate treatment promotes hair follicle growth by activating dermal papilla cells

FEBS Open Bio, EarlyView.
5‐Aminolevulinic acid combined with ferric ammonium citrate (5‐ALA/FAC) stimulates dermal papilla cell activity and promotes hair follicle growth. The treatment enhances ERK and AKT signaling, increases hair‐inductive gene expression, and restores dermal papilla function suppressed by dihydrotestosterone and oxidative stress, resulting in enhanced hair

Development of a rapid fractionation tool for natural organic matter [PDF]

, 2010
A rapid natural organic matter (NOM) fractionation tool was developed to enable NOM to be classified by hydrophobicity at the water treatment works and in the catchment.
