3D Knitted Interfacial Solar Steam Generator for High‐Efficiency and Long‐Term Seawater Desalination

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrophobic bottom provides buoyancy to keep the evaporator floating, and directional vertical spacer yarn supplies sufficient water. The knitted photothermal layer efficiently converts solar energy via multiple light reflections. The Marangoni effect induced by edge yarn accelerates the backflow of salt ions, preventing salt accumulation in the ...

Rhodium‐Catalyzed Carbene Transfer to Isocyanides Using Zinc Carbenoids

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A diazo‐free rhodium‐catalyzed carbene transfer to isocyanides using zinc carbenoids generated from α‐acyloxy halides is reported. This mild protocol furnishes ketenimines that can either be hydrolyzed to amides or intercepted with trimethylsilyl azide or carboxylic acids to give tetrazoles and imides, respectively.

Mono‐dimensional, two‐dimensional and Doppler echocardiographic measurements in healthy Standardbred neonatal foals in the first 5 days of life

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Bodyweight, age and breed influence the echocardiographic assessment of foals. There are no echocardiographic studies in Standardbred neonatal foals. Objectives To describe echocardiographic values for selected variables, evaluate intra‐ and inter‐observer variability and assess cardiac changes in the first 5 days of life in healthy

Open letter: The need for a site‐based biodiversity standard measuring and certifying impacts from nature‐based projects

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Despite growing investment in restoration, weak accountability and poor biodiversity monitoring mean many projects fail to achieve ecological recovery. The Global Biodiversity Standard (TGBS) offers a practical way to ensure that restoration finance delivers measurable gains for nature.

A Fast True Time-Delay Wideband Multi-Beam Beamforming Algorithm Based on a 16-Beam Approximate-DVM

open access: yesIEEE Access
True-time-delay (TTD) beamformers can generate wideband squint-free beams in analog and digital signal domains. The delay Vandermonde matrix (DVM) was introduced as a mathematical model that represents TTD-based multi-beam beamformers while reducing the ...
