Hybrid polymer-CdSe solar cells with a ZnO nanoparticle buffer layer for improved efficiency and lifetime

open access: yes, 2011
We report the use of a solution-processed ZnO nanoparticle buffer layer in hybrid solar cells based on blends of poly(3-hexylthiophene)(P3HT) and CdSe quantum dots.

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

open access: yesFEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Buffer-regulated biocorrosion of pure magnesium

open access: yes, 2012
Magnesium (Mg) alloys are being actively investigated as potential load-bearing orthopaedic implant materials due to their biodegradability in vivo. With Mg biomaterials at an early stage in their development, the screening of alloy compositions for ...

Cell surface CD11c as a neutrophil aging marker molecule

open access: yesFEBS Open Bio, EarlyView.
Cell surface CD11chi neutrophils were more aged and had better phagocytic function than CD11c−/lo neutrophils. Transcriptomic analysis of CD11chi neutrophils and CD11c−/lo neutrophils in pediatric population showed that the most difference was seen in infants.

The influence of AlN buffer layer thickness on the properties of GaN epilayer

open access: yes, 2004
The influence of low-temperature AlN buffer layer thickness on GaN epilayer was investigated by triple-axis X-ray diffraction (XRD) and photoluminescence measurements. A method was proposed to measure the screw and edge dislocation densities by XRD.

BCG vaccination potentiates oxidative phosphorylation in neonatal myeloid‐derived suppressor cells

open access: yesFEBS Open Bio, EarlyView.
BCG vaccination enhances oxidative phosphorylation in neonatal MDSCs, impairing their immunosuppressive function. It upregulates electron transport chain genes and mitochondrial activity, increasing ATP and oxygen consumption. Pharmacological OXPHOS inhibition partially restores suppressive capacity, confirming causality.

Quasi‐Freestanding Graphene via Sulfur Intercalation: Evidence for a Transition State

open access: yesAdvanced Materials Interfaces
Sulfur intercalation of a carbon rich (63×63)R30∘ reconstruction on silicon carbide, also known as buffer layer, is reported. In a two‐zone furnace a sulfur rich precursor is heated and the gaseous species is transported for intercalation by an argon ...

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

open access: yesFEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...

Influence of Overlay Welding Process on the Morphology, Microstructure, and Performance of the Overlay Layer

open access: yesMetals
This study investigates the effects of welding parameters and the addition of a buffer layer on the morphology, microstructure, mechanical properties, and corrosion resistance of the overlay layer during overlay welding. This paper uses Q235 steel as the

Influence of AlN buffer layer thickness on the properties of GaN epilayer on Si(111) by MOCVD

open access: yes, 2008
The effect of thickness of the high-temperature (HT) AlN buffer layer on the properties of GaN grown on Si(111) has been investigated. Optical microscopy (OM), atomic force microscopy (AFM) and X-ray diffraction (XRD) are employed to characterize these ...
