A Soft Microrobot for Single‐Cell Transport, Spheroid Assembly, and Dual‐Mode Drug Screening

Advanced Materials, EarlyView.
A soft, untethered hydrogel microrobot enables precise single‐cell delivery, self‐assembly into 3D spheroids, and real‐time thermal actuation. Driven by light‐induced convection and embedded with gold nanorods and temperature sensors, the microrobot guides cells, modulates local microenvironments, and supports drug testing.

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, EarlyView.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Farmers’ Protests in Germany: Media Coverage and Types of Bias

Agribusiness, EarlyView.
ABSTRACT The German farmers’ protests of 2024 sparked widespread media coverage and public debate. Yet, media coverage was not always positive, reflecting the media's attention‐seeking and selective focus. Occurrences of farmers blocking media outlets reflected distrust in how their concerns were portrayed.

Research on the Detoxification of Municipal Solid Waste Incineration Fly Ash: Organic Acid Washing Pretreatment Coupled With Cement/DDTC Stabilization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Heavy metals in municipal waste incineration fly ash are potentially harmful to the ecological environment and human health. To mitigate the hazards of fly ash, this study attempts to detoxify fly ash through organic acid washing pretreatment coupled with cement/sodium diethyldithiocarbamate (DDTC) solidification.

Adsorption Desulfurization of Liquid Fuel Using a Blend of Date Stones and Walnut Shells by Box–Behnken Design

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A specific microporous KOH/activated‐biochar (K/BC) was produced from a blend of date stones (DS) and walnut shells (WS) and used in the adsorptive desulfurization (ADS) of two types of model fuel DBT/n‐hexane (S‐hex), DBT/cyclohexane (S‐cyclohex).

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...
