Simple (YGa)2O3/F‐SnO2 Heterojunction‐Based Solar‐Blind Ultraviolet Photodetector Operable in Two Modes With Superb Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Yttrium doping was proposed to expand the bandgap and inhibit the oxygen vacancies of Ga2O3 to form (YGa)2O3 alloy with reduced background carriers and trap centers. Beneficially, simple vertical‐structured (YGa)2O3/FTO heterojunction photodetectors exhibit superb performance with particularly low dark current and fast photoresponse in both self‐driven

Breaking the Temperature Barrier: Ultra‐Stable SiHfBCN Ceramic Coatings for High‐Temperature Pressure Sensing

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A 3D conductive net including HfC(N) conductive nanodomains and in‐situ carbon ribbons was generated within the amorphous SiHfBCN matrix by a new molecular‐level composition and microstructure design strategy, making a smooth and dense polymer‐derived SiHfBCN ceramic coatings exhibits excellent electrical conductivity, wide‐temperature sensing, cycling

Ground‐ and Excited‐State Mixed Valency in a 4,4′‐Bipyridine‐Bridged Bimetallic Di‐Ruthenium Complex

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Photoinduced mixed‐valence interactions across a 4,4′‐bpy bridge were studied. MLCT excited states in the bimetallic complex are longer‐lived than in the monometallic reference, thanks to metal–metal electronic coupling and hole delocalization, but are still shorter than the nanosecond timescale relevant for diffusional reactivity.

Zinc‐Mediated Photodegradation of Nitrophenols in Aqueous Solution: Devising Environmental Mitigation Strategies With Ultrafast Spectroscopic Insights

open access: yesElectron, EarlyView.
We implement a suite of steady‐state and time‐resolved spectroscopic techniques to elucidate the zinc‐mediated photodegradation of nitrophenols in aqueous solution. From ultrafast electronic spectroscopy of aci‐nitrophenol on femtosecond‐to‐nanosecond timescales to tracking photoproducts with absorption and vibrational signatures (through ground‐state ...

PtTe2 interface engineering for enhanced near‐infrared photoresponse in black silicon photodetectors

open access: yesInfoMat, EarlyView.
Highly responsive near‐infrared (NIR) photodetectors are essential for advanced photoelectric systems. In this work, a high‐responsivity NIR photodetector is developed by integrating a PtTe2/black silicon (B‐Si) heterostructure into a Si p‐i‐n diode, where B‐Si introduces sub‐bandgap defect states to enhance NIR absorption and the PtTe2 layer induces ...

Projected 21st Century Changes in Precipitation and Temperature Over Italy Using CMIP6 CMCC‐CM2‐SR5 Model and COSMO‐CLM Dynamical Downscaling

open access: yesInternational Journal of Climatology, EarlyView.
This study evaluates the COSMO‐CLM regional climate model over Italy under CMIP6 scenarios. Compared to its driving global model, COSMO‐CLM reduces temperature biases by 50%–75% and better represents precipitation and extremes, adding critical mesoscale detail.
