Microstructures and mechanical properties of pure tantalum processed by high-pressure torsion

, 2014
A body-centred cubic (BCC) structure metal, tantalum, was processed by high- pressure torsion (HPT) at room temperature with different numbers of rotations. The microstructural evolution was studied by electron backscatter diffraction (EBSD).

Bright Monocompound Metal Halide Scintillator for Fast Neutron Radiography

Advanced Functional Materials, EarlyView.
Metal halide scintillator, tetraphenylphosphonium manganese bromide (TPP2MnBr4), provides a significant benefit for fast neutron imaging. A fourfold increase in efficiency over traditional zinc sulfide screens is achieved by efficiently utilizing neutron interactions within its homogeneous structure.

Oligohistidine‐Functionalized Single‐Walled Carbon Nanotube‐Guided RNA Delivery to Improve Shoot Regeneration Efficiency in Plant Calli

Advanced Functional Materials, EarlyView.
The pH‐sensitive His6‐SWNTs, which is functionalized with oligohistidine, can deliver STTM396 molecules into callus cells. The STTM396–SWNT complex treatments enhance shoot regeneration efficiency by regulating the miR396‐GRF module in Arabidopsis and tomato calli.

Smart Nanogels as Enzyme‐Driven Nanomotors for Navigating Viscous Physiological Barriers

Advanced Functional Materials, EarlyView.
Two families of urease‐powered nanomotors (NMs), with and without a p‐(2‐hydroxyethyl methacrylate) (p‐HEMA) shell, have been successfully prepared. Both types exhibit effective motion in highly viscous synovial fluid media at low urea concentrations (25 mM).

Oxygen Evolution Reaction by Ni‐Hexacyanoferrates Nanocubes Integrated with Trigonal Selenium: Effect, Properties and Performances

Advanced Functional Materials, EarlyView.
This work describes a novel approach to obtain composite submicrometric structures of nickel hexacyanoferrate integrating trigonal selenium with the aim of enhancing the catalytic efficiency in oxygen evolution reaction (OER). Interestingly, the nanostructures undergo a cube‐to‐sphere transition that optimizes surface properties, leading to superior ...

Non-Poissonian photon statistics from macroscopic photon cutting materials

Nature Communications, 2017
Photon-cutting materials provide a way around efficiency limits for energy conversion by absorbing high-energy photons and ‘cutting’ them into multiple low-energy excitations.
