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

Improved Design of Self-tapping Screw (STS) for Korean Larch and Red Pine Cross Laminated Timber (CLT)

open access: yesBioResources
In this study, the finite element method (FEM) was used to determine the effect of the optimal angle of the thread and double thread application among self-tapping screw (STS) design information on the improvement of the withdrawal capacity of the ...

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

open access: yesAdvanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

THE CAPACITY OF THIRD COUNTRIES TO NEGOTIATE BILATERAL AGREEMENTS WITH THE UK UNDER WITHDRAWAL ARRANGEMENTS

open access: yesEU AND COMPARATIVE LAW ISSUES AND CHALLENGES SERIES, 2019
Having in mind that this is the first time that a Member State decided to withdraw from the EU pursuant to Article 50 TEU there are many aspects of this process that attract the attention of scholars studying EU related issues. Regardless of the outcome of the ongoing political debate and the course of action that will be taken eventually, after the ...

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Effects of cerium oxide nanoparticle on liver oxidative stress and morphological changes in opium withdrawal rats

open access: yesToxicology Reports
Since oxidative stress increased during opioid withdrawal, this study aimed to evaluate the effects of cerium oxide nanoparticles (CeONP) on oxidative stress markers in rat livers.

Myrcene‐Based Tailored Co‐Polymers as Active Pharmaceutical Excipients: Bio‐Based Solutions for Mucoadhesive Excipients

open access: yesAdvanced Functional Materials, EarlyView.
Mucoadhesive amphiphilic block and statistical copolymers were synthesized via Reversible Addition–Fragmentation Chain Transfer polymerization from bio‐sourced myrcene and polyethylene glycol methacrylate. The resulting polymers exhibit narrow molar‐mass distributions, high regioselectivity, well‐defined microstructures, and tend to self‐assemble into ...
