We dem.nstrated a new type of m.X phase m.terial， Chrom.um.Titanium.Alum.num.Carbide (Cr2TiAlC2) polym.r film.to generate a passively Q-switched erbium.doped fiber laser. The film.thickness was m.asured around 45 μm.which was fabricated using the em.edding m.thod with PVA polym.r as hoster. The SA film.dem.nstrates a dual-wavelength passively Q-switched erbium.doped fiber laser （EDFL） which operates at 1531 nm.and 1560.19 nm. respectively. The Q-switching pulse duration could be varied from.2.46 μs to 770 ns while the repetition rate varied from.92.76 kHz to 106.6 kHz with an increasing input pum.ing range of 154 m. to 300 m.. The m.xim.m.output power and pulse energy of 15.05 m. and 141.18 nJ were obtained at a m.xim.m.input power of 300 m.， respectively. To the best of our knowledge， this is the first tim. that on dual-wavelength Q-switched EDF laser by Cr2TiAlC2as SA.

The technique of producing hydrogen by utilizing green and renewable energy sources is called green hydrogen production. Therefore, by im.lem.nting this technique, hydrogen will becom. a sustainable and clean energy source by lowering greenhouse gas em.ssions and reducing our reliance on fossil fuels. The key benefit of producing green hydrogen by utilizing green energy is that no harm.ul pollutants or greenhouse gases are directly released throughout the process. Hence, to guarantee all of the environm.ntal advantages, it is crucial to consider the entire hydrogen supply chain, involving storage, transportation and end users. Hydrogen is a prom.sing clean energy source and targets plan pathways towards decarbonization and net-zero em.ssions by 2050. This paper has highlighted the techniques for generating green hydrogen that are needed for a clean environm.nt and sustainable energy solutions. m.reover, it sum.arizes an overview, outlook and energy transient of green hydrogen production. Consequently, its perspective provides new insights and research directions in order to accelerate the developm.nt and identify the potential of green hydrogen production. Hydrogen is a prom.sing clean energy source and a pathway towards decarbonization and net-zero em.ssions by 2050. This article provides perspective on techniques for generating green hydrogen that are needed for a clean environm.nt and sustainable energy solutions. Graphical Abstract

Despite substantial progress in the treatm.nt of castration-resistant prostate cancer (CRPC), including radiation therapy and im.unotherapy alone or in com.ination, the response to treatm.nt rem.ins poor due to the hypoxic and im.unosuppressive nature of the tum.r m.croenvironm.nt. Herein, we exploited the bioreactivity of novel polym.r–lipid m.nganese dioxide nanoparticles (PLm.s) to rem.del the tum.r im.une m.croenvironm.nt (TIm.) by increasing the local oxygen levels and extracellular pH and enhancing radiation-induced im.unogenic cell death. This study dem.nstrated that PLm. treatm.nt sensitized hypoxic hum.n and m.rine CRPC cells to radiation, significantly increasing radiation-induced DNA double-strand breaks and ultim.tely cell death, which enhanced the secretion of dam.ge-associated m.lecular patterns, attributable to the induction of autophagy and endoplasm.c reticulum.stress. Reoxygenation via PLm.s also polarized hypoxic m.rine RAW264.7 m.crophages toward the m. phenotype, enhancing tum.r necrosis factor alpha release, and thus reducing the viability of m.rine CRPC TRAm.-C2 cells. In a syngeneic TRAm.-C2 tum.r m.del, intravenous injection of PLm.s suppressed, while radiation alone enhanced recruitm.nt of regulatory T cells and m.eloid-derived suppressor cells. Pretreatm.nt with PLm.s followed by radiation down-regulated program.ed death-ligand 1 and prom.ted the infiltration of antitum.r CD8+ T cells and m. m.crophages to tum.r sites. Taken together, TIm. m.dulation by PLm.s plus radiation profoundly delayed tum.r growth and prolonged m.dian survival com.ared with radiation alone. These results suggest that PLm.s plus radiation is a prom.sing treatm.nt m.dality for im.roving therapeutic efficacy in radioresistant and im.unosuppressive solid tum.rs.
