Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

In the eye of the COVID-19 cytokine storm

open access: yesNature reviews. Immunology, 2020
volume 20 | mAY 2020 | 277 Profiling of the innate immune cell types present in the KPC­ OG and KPL­ OG mouse models indicated that cDCs were markedly reduced in number and function in pancreatic tumours compared with in lung tumours. In the later stages

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

open access: yesAdvanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Robust-yet-fragile nature of partly engineered social-ecological systems: a case study of coastal Bangladesh

open access: yesEcology and Society, 2017
Modern social-ecological systems are often partly engineered to enhance the robustness (or reduce the variance) of human welfare to environmental fluctuations over a foreseeable time horizon.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

High‐Concentration Mesogen‐Assisted Exfoliation of Low‐Dimensional Nanomaterials for Achieving Ultralow‐Temperature Actuations of Liquid Crystal Elastomers

open access: yesAdvanced Functional Materials, EarlyView.
Most matter is nominally frozen in the polar regions or space, and liquid crystal materials are no exception. Consequently, soft actuators, including liquid crystal elastomers (LCEs), are inoperative under such extreme cold in response to stimuli, as their motion relies on mechanical deformation.

FORECASTING SEVERE CONVECTIVE STORMS

open access: yesНаука. Инновации. Технологии, 2022
Introduction: One of the most difficult tasks facing modern synoptic meteorology is the forecasting of heavy convective storms (tornadoes). Heavy convective storms, extratropical hurricanes, tornadoes, whose products are storm-storming processes, are a ...

Generation of a global synthetic tropical cyclone hazard dataset using STORM

open access: yesScientific Data, 2020
Over the past few decades, the world has seen substantial tropical cyclone (TC) damages, with the 2017 Hurricanes Harvey, Irma and Maria entering the top-5 costliest Atlantic hurricanes ever.

Single‐Step Synthesis of In‐plane 1T'‐2H Heterophase MoTe2 for Low‐Resistance Contacts

open access: yesAdvanced Functional Materials, EarlyView.
A single‐step CVD method is developed to synthesize seamless in‐plane 1T'‐2H MoTe2 heterophase junctions with precise phase control and uniform large‐area coverage. The resulting transistors, incorporating 1T' MoTe2 contacts and 2H MoTe2 channels, exhibit ultralow contact resistance, offering a scalable solution to the long‐standing challenge of ...

Inversion of Global Thermospheric Density Map Based on Satellite Measurements Using Deep Learning RFR Network

open access: yesEarth and Space Science
The estimation error of neutral mass density is a major source of uncertainty in calculating thermospheric drag, which is the primary non‐gravitational perturbation affecting satellites in low Earth orbit.
