Progress and Application of Multifunctional Hydrogel in Radioactive Skin Injury

Advanced Materials Interfaces, EarlyView.
This review examines healing challenges in radiation‐wound injuries, where ionizing radiation impairs immune and tissue repair processes. Hydrogels, with their biocompatibility, antimicrobial properties, and drug delivery capabilities, present a transformative solution. It compares hydrogel efficacy in radiation‐induced versus common wounds, highlights

Performance of limestone‐based sorbent for sorption‐enhanced gasification in dual interconnected fluidized bed reactors

AIChE Journal, Volume 69, Issue 1, January 2023., 2023
Abstract A possibility to carry out sorption‐enhanced gasification (SEG) is represented by its integration with the calcium looping concept in dual interconnected fluidized beds (DIFB). This article is focused on the sorbent CO2 uptake performance and attrition/fragmentation tendency when operating conditions simulating those of a DIFB‐SEG process are ...

Additive Manufacturing of Stretchable Zipping Electrostatic Actuators through Spray Encapsulation of a Frozen Liquid

Advanced Materials Technologies, EarlyView.
This work presents a method to print multi‐layer elastomer structures containing liquid cavities, where the fluid is incorporated as part of the printing process by freezing it, thus avoiding the conventional final filling step. We demonstrate this process by fabricating and characterizing dense arrays of zipping electrostatic actuators.

Coupling hydrothermal liquefaction and aqueous phase reforming for integrated production of biocrude and renewable H2

AIChE Journal, Volume 69, Issue 1, January 2023., 2023
Abstract Lignin‐rich stream from lignocellulosic ethanol production was converted into biocrude by continuous hydrothermal liquefaction (HTL) while hydrogen was produced by aqueous phase reforming (APR) of the HTL aqueous by‐product. The effects of Na2CO3 and NaOH were investigated both in terms of processability of the feedstock as well as yield and ...

Zero‐Power, Optical Toxic Gas and Vapor Sensors Utilizing Printed Nematic Liquid Crystal Patterns on Selectively Reactive Substrates

Advanced Sensor Research, EarlyView.
Fast response, zero‐power, text or image sensors utilizing light transmission or reflection, and no unfavorable color change judgments, are fabricated using printed nematic liquid crystals patterned on reactive alignment layers, permit ppt‐ to ppb‐level sensitivity, and were field‐tested with active firefighters.

Online Data Poisoning Attack [PDF]

arXiv, 2019
We study data poisoning attacks in the online setting where training items arrive sequentially, and the attacker may perturb the current item to manipulate online learning. Importantly, the attacker has no knowledge of future training items nor the data generating distribution.

Sustainable Flame‐Retardant Poly Lactic Acid Biocomposites Reinforced with Polyphosphate‐Enriched Microalgae: Unlocking the Potential of Hyper‐Compensation

Advanced Sustainable Systems, EarlyView.
This study explores microalgae cultivation for wastewater treatment and enhancement of poly lactic acid (PLA)‐based biocomposites. It achieves up to 99.9% nutrient removal, increases biomass productivity by 322%, and demonstrates a triphasic luxury phosphorus uptake system. Incorporation into PLA improves fire‐retardant properties, suggesting potential

On the Relentless Pursuit of an Oral Insulin Delivery System: How Far is Too Far?

Advanced Therapeutics, EarlyView.
Injectable insulin preparations have far outpaced oral ones by virtue of adequate bioavailability and are driven by innovations, including insulin pumps, real‐time blood glucose monitoring, and artificial intelligence. In contrast, oral insulin delivery systems, including nanomedicines, continue to struggle and lag due to varied reasons.

Multiple Roles of Alkanethiolate‐Ligands in Direct Formation of H2O2 over Pd Nanoparticles

Angewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
Under the reaction conditions of direct H2O2 formation over alkylthiolate(RS) decorated Pd, we find that the RS is oxidized yielding RSO2 as the effective ligand. The RSO2 ligand shows superior ability for proton transfer to the intermediate surface species OOH, which accelerates the formation of H2O2.
