Fast and long-lasting Fe(Ⅲ) reduction by boron toward green and accelerated Fenton chemistry.

open access: yesAngewandte Chemie, 2020
Generation of hydroxyl radicals in the Fenton system (Fe(II)/H 2 O 2 ) is seriously limited by the sluggish kinetics of Fe(III) reduction and fast Fe(III) precipitation.

Pressure-induced metallization in solid boron [PDF]

open access: yes, 2001
Different phases of solid boron under high pressure are studied by first principles calculations. The $\alpha$-B$_{12}$ structure is found to be stable up to 270 GPa.

A New Class of Boron Nanotube

open access: yes, 2011
The configurations, stability and electronic structures of a new class of boron sheet and related boron nanotubes are predicted within the framework of density functional theory. This boron sheet is sparser than those of recent proposals.

van der Waals heterostructures combining graphene and hexagonal boron nitride

open access: yesNature Reviews Physics, 2019
As the first in a large family of 2D van der Waals (vdW) materials, graphene has attracted enormous attention owing to its remarkable properties. The recent development of simple experimental techniques for combining graphene with other atomically thin ...

Meristic and biometric parameters of spined loach, Cobitis taenia (L.) (Cypriniformes, Cobitidae) from Zegrzyński Dam Reservoir [PDF]

open access: yesActa Ichthyologica et Piscatoria, 1994
The paper presents the results of studies on meristic and biometric parameters in spined loach, Cobitis taenia (L.) from Zegrzyński Dam Reservoir. Body proportions were determined as well as the relations between the parameters under study and body and ...

Influence of boron content on the fracture toughness and fatigue crack propagation kinetics of bainitic steels [PDF]

open access: yes, 2016
The relatively good combination of high strength and ductility makes bainitic steels a candidate to replace many other steels in industrial applications. However, in service, ductility and strength are not up to standard requirements.

Effect of Foot Orthoses on Midfoot Pain and the Volume of Bone Marrow Lesions in the Midfoot: A Randomized Mechanism of Action Study

open access: yesArthritis Care &Research, EarlyView.
Objective Foot orthoses are thought to improve pain by potentially modifying internal mechanical forces. To test this, we explored whether foot orthoses can modify patterns of bone marrow lesions (BMLs) in people with midfoot pain. Methods Forty‐two people were recruited with midfoot pain, and magnetic resonance imaging–confirmed midfoot BMLs ...

Novel Precursors for Boron Nanotubes: The Competition of Two-Center and Three-Center Bonding in Boron Sheets

open access: yes, 2007
We present a new class of boron sheets, composed of triangular and hexagonal motifs, that are more stable than structures considered to date and thus are likely to be the precursors of boron nanotubes. We describe a simple and clear picture of electronic

High thermal conductivity in cubic boron arsenide crystals

open access: yesScience, 2018
Moving the heat aside with BAs Thermal management becomes increasingly important as we decrease device size and increase computing power. Engineering materials with high thermal conductivity, such as boron arsenide (BAs), is hard because it is essential ...
