Summary: In this study, perovskite films were deposited using the CVD method at different temperatures, resulting in phase conversion and increased grain size with higher deposition temperatures. The phase transition mechanism and photoexcited state dynamics were investigated, showing that the film deposited at 750 degrees C had low trap-state density and large crystalline grain size. A photodetector based on perovskite films exhibited high photocurrent and an on/off ratio of around 2.5 x 10(4).

Summary: Vapor deposition shows great potential for scalable and industrial processing of perovskite solar cells, offering advantages such as toxicity-free processing, thickness control, and uniform coating. However, the different volatilities of the organic and inorganic components of perovskites currently require multiple thermal sources or two-step deposition. In this study, single-source, single-step pulsed laser deposition is demonstrated for the deposition of tunable MA(1-x)FA(x)PbI(3) thin films. The room temperature formation of cubic alpha-phase MA(1-x)FA(x)PbI(3) films is achieved by controlling laser ablation of a solid target with adjustable ratios of MAI:FAI:PbI2. The target-to-film transfer of the ablated species is confirmed, and proof-of-concept solar cells with 14% efficiency are demonstrated. This research paves the way for future developments in industry-compatible vapor deposition methods for perovskite solar cells.

Summary: Air pollution caused by nitrogen oxides (NO2) from exhaust gas is a long-standing problem that requires new capture and abatement technologies. Electrochemical conversion of NO2 to value-added chemicals is a promising strategy for mitigating imbalances in the global nitrogen cycle. We propose an electrochemical cell based on an aqueous Zn||NO2 system with a nano-NiO catalyst. The cell efficiently captures and converts NO2 to NO2- and value-added NH3 while generating electric power.

Summary: In this study, a series of organic room-temperature phosphorescent (RTP) polymers with tunable color luminescence were prepared by incorporating phosphorescent rotors into polymer backbones. Experimental and theoretical calculations revealed that the various molecular conformations of the monomers are responsible for the excitation wavelength-dependent (Ex-De) RTP behavior. By gaining insights into the underlying mechanism, dynamic control of Ex-De RTP behavior was achieved through thermal energy driven molecular rotations of the monomers. These findings provide new opportunities for controlling the response behaviors of smart-responsive RTP materials through external stimuli rather than conventional covalent modification methods.

Summary: A robust aqueous solid-electrolyte interphase (SEI) is successfully constructed by introducing a ladderized heterocyclic polymer electrode into a water-in-salt electrolyte, enabling ultra-stable dual-ion storage with long-term calendar life. The sophisticated SEI composed of fluorinated/oxygenated species is formed through a proton co-intercalation process, consuming water in the solvation shell of Li+ ions to trigger the decomposition of organic anions. This new SEI formation path is expected to broaden the applications of aqueous SEI and facilitate the design of versatile electrode materials for advanced aqueous Li-ion batteries (ALIBs).

Summary: Inorganic perovskite nanosheets (Cs3Bi2I9, Cs3Sb2I9) are synthesized at the liquid-air interface by drop-casting the precursor solution with the addition of iodine. The thickness and lateral size of the nanosheets can be adjusted through the iodine concentration. The iodine repairs iodine vacancies during perovskite growth, resulting in enhanced optical and optoelectronic properties. The liquid-air interfacial growth of ultrathin perovskites provides flexibility for constructing perovskite-based heterostructures and devices at the atomic scale.

AHMM exhibits excellent selectivity for CN- without interference from other anions in an aqueous DMSO system. Moreover, AHMM can quantitatively recognize CN- in tap water and visualize CN- in food samples and biological samples through fluorescence imaging.
