In situ coupling of NiFe nanoparticles on carbonized wood for oxygen evolution reaction

open access: yesCatalysis Communications, 2022
Inspired by the 3D hierarchical porous structure and abundant hydroxyl groups of wood, we used basswood as a biological template to synthesize NiFe/porous carbon (C) through an impregnation and pyrolysis strategy. The optimized NiFe/C composite exhibited

Observation of the East-West Anisotropy of the Atmospheric Neutrino Flux [PDF]

open access: yes, 1999
The east-west anisotropy, caused by the deflection of primary cosmic rays in the Earth{close_quote}s magnetic field, is observed for the first time in the flux of atmospheric neutrinos.

Self-adapted clustering of solute atoms into a confined two-dimensional prismatic platelet with an ellipse-like quasi-unit cell

open access: yesIUCrJ, 2018
This paper reports a new structured prismatic platelet, self-assembled by an ellipse-like quasi-unit cell, precipitated in Mg–In–Yb and Mg–In–Ca ternary alloys and aged isothermally at 200°C using aberration-corrected high-angle annular dark-field ...

Giant elastocaloric effect and exceptional mechanical properties in an all-d-metal Ni–Mn–Ti alloy: Experimental and ab-initio studies

open access: yesMaterials & Design, 2019
Exploring novel materials with superior elastocaloric effect (eCE) is a central issue for the development of eCE refrigeration technique. In this work, we report a giant adiabatic temperature change ΔTad of −20.4 K in the 〈100〉-textured all-d-metal ...

Evidence for anisotropy of cosmic acceleration [PDF]

open access: yesAstronomy & Astrophysics, 2018
Observations reveal a “bulk flow” in the local Universe which is faster and extends to much larger scales than are expected around a typical observer in the standard ΛCDM cosmology.

Understanding and measuring mechanical signals in the tumor stroma

open access: yesFEBS Open Bio, EarlyView.
This review discusses cancer‐associated fibroblast subtypes and their functions, particularly in relation to extracellular matrix production, as well as the development of 3D models to study tumor stroma mechanics in vitro. Several quantitative techniques to measure tissue mechanical properties are also described, to emphasize the diagnostic and ...

The anisotropy of personal space

open access: yesPLOS ONE, 2019
Violations of personal space are associated with discomfort. However, the exact function linking the magnitude of discomfort to interpersonal distance has not yet been specified. In this study, we explore whether interpersonal distance and discomfort are isotropic with respect to uncomfortably far or close distances.

An efficient strategy for producing RNA‐free Nucleocapsid protein of SARS‐CoV‐2 for biochemical and structural investigations

open access: yesFEBS Open Bio, EarlyView.
Cleavable N‐terminal Thioredoxin fusion enabled soluble expression and purification of otherwise insoluble SARS‐CoV‐2 Nucleocapsid (N) protein. A four‐step purification strategy yielded highly homogeneous, RNA‐free N protein. Binding assays showed high RNA affinity (Kd ~ 28 nm). The study will facilitate high‐resolution structural studies of N protein,
