Systematic Analysis of Plasma‐Derived Extracellular Vesicle‐Enriched Samples in Age‐Related Macular Degeneration Reveals Oxidative Stress Linked to Altered Lipid and Protein Profiles

open access: yesJournal of Extracellular Biology, Volume 5, Issue 9, September 2026.
ABSTRACT Vision impairment caused by age‐related macular degeneration (AMD) is a global health priority. Retinal pathology is driven by ageing and exacerbated by genetic and environmental risk factors. Peripheral blood circulation is increasingly recognised as a contributor to disease initiation and progression, and a source of biomarkers to support ...

Experimental Investigation of Isothermal Section of the B-Cr-Fe Phase Diagram at 1353 K

open access: yesAdvances in Materials Science and Engineering, 2017
The isothermal section of the B-Cr-Fe ternary system was studied experimentally at 1353 K. X-ray diffraction and scanning electron microscopy equipped with EDX analyzer were used for determination of phase equilibria and composition of the coexisting ...

In Situ Engineering an S‐Scheme MnS/MnB‐MBene Heterojunction With Spatially Separated Redox Sites for Efficient H2 Evolution and 5‐HMF Oxidation

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Photocatalytic H2 evolution coupled with biomass upgrading offers a sustainable route for clean energy conversion and high‐value chemical synthesis. Herein, an in situ grown S‐scheme MnS/MnB‐MBene heterojunction (denoted as SMx) was fabricated via alkaline etching of Mn2AlB2 followed by controlled sulfurization.

Certain physical properties of cobalt and nickel borides [PDF]

open access: yes, 1981
The temperature dependence of the electrical resistivity, the thermal conductivity, and the thermal emf of cobalt and nickel borides were studied. In the case of the nickel borides the magnetic susceptibility and the Hall coefficient were determined at ...

Electron Transport in Boron-Rich Borides

open access: yes, 1987
Boron-rich borides represent a class of unique semiconductors. They combine the physico-chemical properties of refractory crystals with the electrical, optical, thermal properties typical for amorphous semiconductors [ 1–3 ].

Chemical Removal of Al From Layered Mn2AlB2: Toward 2D‐MBene and Its Application to MgH2 Hydrogen Storage

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Two‐dimensional Mn‐based MBenes remain challenging to synthesize due to structural instability during etching. Herein, Mn2AlB2 was employed as a precursor to systematically investigate Al removal via HF, NaOH, and a gas–solid route using PVDF‐derived HF.

Unveiling Entropy‐Driven Hard‐Tough Synergy Mechanisms in High‐Entropy Carbonitride Ceramics

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT High‐entropy ceramics manifested promise for extreme environments, yet their phase stability and mechanical synergy mechanisms remain elusive. Herein, entropy‐difference carbonitrides, including (TaTiV)CN, (TaTiVNb)CN, and (TaTiVNbHf)CN, were designed and consolidated via spark plasma sintering.

Ultralow‐Ru‐Activated Amorphous NiCoFe Medium‐Entropy Boride for Overall Water Splitting in a Proton‐Exchange‐Membrane Electrolyzer

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Platinum‐free electrocatalysts that combine high activity for the hydrogen evolution reaction (HER) with the stability required for proton‐exchange‐membrane (PEM) water electrolysis remain a central challenge for scalable green‐hydrogen production.

Rapid and low‐temperature synthesis of MoAlB MAB phase by using stress‐induced Al‐particles

open access: yesInternational Journal of Ceramic Engineering & Science
Currently, MoAlB particles are produced at 1000°C and higher temperatures. In this manuscript, we report the rapid synthesis of MoAlB by altering the stress of Al particles to affect Al reactivity.
