A new strategy capable of detecting explosive peroxide vapor via deboronation reaction induced fluorescence quenching has been developed. Using ordered assembly arrays of ZnO nanorods as catalyzing substrates, the deboronation reaction was 42 times faster than that on quartz substrates, which resulted in a very fast response and high sensitivity.

In this work, we have investigated the thermal features of hydrogen peroxide-based energetic materials formulations. Initial research has shown that both the auxiliary oxidiser (sodium nitrate, potassium nitrate or calcium nitrate) and sensitising agent (glass microspheres) have significant influence on the rate of hydrogen peroxide decay in such formulations. In terms of the thermal features of the tested energetic materials, a similar and significant influence of the auxiliary oxidising agent and sensitising agent choice was observed.

The emerged apoptosis/ferroptosis synergistic platinum-based therapy has attracted a lot of attention but is far from clinic use due to high systemic toxicity. Herein, a series of novel precise carrier-free self-assembled platinum(IV) nanoparticles with lipid regulation effect named FSPNPs (NPs-NPs) were constructed via connecting fenofibrate acid (FA) to cisplatin or oxaliplatin-derived platinum(IV)-intermediates with disulfide bonds. FSPNPs can be stimulated by high-glutathione/ascorbic acid and acidity environment to produce an "explosion-like" cascade release process.

Cancer cells possess an efficient redox system, enabling them to withstand oxidative damage induced by treatments, especially in hypoxia areas and ferroptosis can disrupt redox homeostasis in cancer cell. Herein, GSH-sensitive nanoparticles are constructed that induce ferroptosis by long-lasting GSH depletion and enhanced PDT. Carbonic anhydrase IX inhibitor, protoporphyrin IX (Por) complexed with Fe and epirubicin (EPI) are grafted to hyaluronic acid (HA) via disulfide bonds to obtain HSPFE and loaded xCT inhibitor SAS for fabricating SAS@HSPFE which is actively targeted to deep hypoxic tumor cells, and explosively releasing EPI, Por-Fe complex and SAS due to at high GSH concentration.

To date, a general approach for the direct α-acyloxylation of cyclic 1,3-dicarbonyls remains challenging. Herein, we report a Pd-catalyzed α-acyloxylation of cyclic 1,3-dicarbonyl-derived hypervalent iodine compounds with highly abundant carboxylic acids. Our approach utilizes a commercially available Pd(OAc) catalyst, which exhibits mild reaction conditions, scalability, operational simplicity, and robustness against moisture and air.

Objectives: To propose a novel forensic diatom examination method, namely the protease-hydrogen peroxide (PHP) digestion method, and to explore its potential application in forensic practice.
Methods: The PHP digestion method was applied to process lung tissues and compared with the traditional nitric acid digestion method in terms of diatom quantity, recovery rate, proportion of diatom fragments, and recovery efficiency of different diatom genera.
Results: The PHP digestion method showed higher diatom quantity, recovery rate, and proportion of diatom fragments compared to the traditional nitric acid digestion method with statistical significance.
