Engineering Strain‐Defects to Enhance Enzymatic Therapy and Induce Ferroptosis

Advanced Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 6, 2024

Abstract The effect of mimetic enzyme catalysis is often limited by insufficient activity and a single therapy not sufficient to meet the application requirements. In this study, multifunctional nanozyme, MMSR‐pS‐PEG, designed fabricated modifying poly (ethylene glycol) grafted phosphorylated serine (pS‐PEG) on mesoporous hollow MnMoO x spheres, followed loading sorafenib (SRF) into pores. Strain engineering‐induced oxygen defects endow nanozyme with enhanced dual‐enzymatic mimic catalase oxidase‐like activities, which catalyze conversion endogenous H 2 O subsequently superoxide ions in acidic tumor microenvironment. Moreover, as an n‐type semiconductor, generates reactive species separating electrons holes upon ultrasonic irradiation simultaneously deplete glutathione holes, thereby further augmenting its catalytic effect. As ferroptosis inducer, SRF restrains system c − indirectly inhibits synthesis, synergistically interacting stimulate promoting lipid peroxidation accumulation downregulation peroxidase 4. These results provide valuable insights design enzymatic high performance highlight promising approach for synergism therapy.

Schottky Junctions with Bi@Bi2MoO6 Core-Shell Photocatalysts toward High-Efficiency Solar N2-to-Ammonnia Conversion in Aqueous Phase

Nanomaterials, Journal Year: 2024, Volume and Issue: 14(9), P. 780 - 780

Published: April 30, 2024

The photocatalytic nitrogen reduction reaction (NRR) in aqueous solution is a green and sustainable strategy for ammonia production. Nonetheless, the efficiency of process still has wide gap compared to that Haber–Bosch one due difficulty N2 activation quick recombination photo-generated carriers. Herein, core-shell Bi@Bi2MoO6 microsphere through constructing Schottky junctions been explored as robust photocatalyst toward NH3. Metal Bi self-reduced onto Bi2MoO6 not only spurs electron hole separation owing junction at interface but also promotes adsorption active sites synchronously. As result, yield N2-to-ammonia conversion reaches up 173.40 μmol g−1 on photocatalysts, much two times bare Bi2MoO6. This work provides new design decarbonization by utilization renewable energy sources.

Journal of Physics Condensed Matter, Journal Year: 2024, Volume and Issue: 36(38), P. 385901 - 385901

Published: June 12, 2024

In this work, we report the development and assessment of nonadiabatic molecular dynamics approach with electronic structure calculations based on linearly scaling subsystem density functional method. The is implemented in an open-source embedded Quantum Espresso/Libra software specially designed for simulations extended systems. As proof applicability method to large condensed-matter systems, examine nonradiative relaxation excess excitation energy pentacene crystals simulation supercells containing more than 600 atoms. We find that increased structural disorder observed larger supercell models induces couplings states accelerates excited states. conduct a comparative analysis several quantum-classical trajectory surface hopping schemes, including two new methods proposed work (revised decoherence-induced instantaneous decoherence at frustrated hops). Most tested schemes suggest fast occurring timescales 0.7-2.0 ps range, but they significantly overestimate ground state recovery rates. Only modified simplified decay mixing yields notably slower 8-14 ps, inhibited recovery.
