Nanozyme‐Integrated Hydrogel Targeting AGEs for Diabetic Osteoarthritis Therapy

Advanced Science, Volume 13, Issue 8, 9 February 2026.
A nanozyme–integrated hydrogel (PTC‐MP) exhibiting with mild photothermal effects is constructed, and a “3R” (restrain‐restore‐reinforce) strategy is proposed for diabetic osteoarthritis (DOA) treatment based on advanced glycation end products (AGEs) targeting.

Lightweight and High‐Strength Carbon Bulk Preparation Via Low‐Temperature Pressureless Sintering of Sugar‐Derived Carbon

Advanced Science, Volume 13, Issue 7, 3 February 2026.
The synergistic effect between crosslinked polyacrylamide and glucose brings the precursor sintering activity with better thermostability, allowing its formation of a coherent carbon structure at lower temperatures (≤ 1200 °C) under ambient pressure.

Mechanochromic Organic Materials: Molecular Mechanisms and Multidimensional Applications

Advanced Physics Research, Volume 5, Issue 2, February 2026.
Mechanochromic (MC) organic materials change color in response to mechanical force. This review elucidates the molecular mechanisms (e.g., aggregation‐induced emission, AIE) and explores their multidimensional applications in sensors, anti‐counterfeiting, biomedical devices, and structural health monitoring, providing a roadmap for future smart ...

New Compounds From the Deep‐sea Sponge Mycale lingua

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
The focus of this study is the scarcely investigated sponge Mycale lingua, found commonly in the North Atlantic Ocean. In total, four compounds are isolated and characterised from three combined M. lingua individuals. Structures are fully elucidated through HR‐LCMS and NMR spectroscopy (1H, COSY, HSQC, HMBC).

Pyridinium Compounds as Sensitisers for Solar Cells

, 2011
The work presented in this thesis concerns the synthesis and study of various RuII polypyridyl complexes and organic chromophores which incorporate strongly electron-accepting and π-conjugated pyridinium groups. Several of these compounds have been studied as potential sensitisers for solar cell applications.The N3 dye, cis-RuII(NCS)2(dcbpy)2 (dcbpy ...

High Potential Isoindoline‐Based Nitroxides Posolytes for Aqueous Organic Redox Flow Batteries

ChemSusChem, Volume 19, Issue 3, February 2026.
A convenient metal‐catalyzed [2 + 2 + 2] cycloaddition enables the synthesis of isoindoline‐based nitroxides as new posolytes for aqueous organic redox flow batteries. The cationic PPO exhibits a 220 mV higher oxidation potential than 4‐TMA‐TEMPO, 3 M solubility in 1 M NaCl, and a cell voltage of 1.56 V.
