Recently, aluminum-based batteries have received extensive attention from researchers because of their advantages over other metals-based batteries in terms of cost, energy density , and safety performance. Herein, we synthesized willow leaf-shape ReSe 2 @C as the positive electrode of aluminum batteries. ReSe 2 , with anisotropic crystal structure, is encapsulated in carbon using weak interlaminar van der Waals force. Its low lattice symmetry increases the ion/electron adsorption sites and reduces the energy barrier for ion intercalation into ReSe 2 layers. The electrochemical analysis and X-ray photoelectron spectroscopy of ReSe 2 @C have ascertained that AlCl 4 - is intercalated/embedded in host material during charging/discharging. The specific discharge capacity of ReSe 2 @C remains 88 mA h g −1 after 1000 cycles at the current density of 100 mA g −1 , with a high Coulomb efficiency of 98%.

The precise phase control of Cs-Pb-Br derivatives from 3D CsPbBr 3 to 0D Cs 4 PbBr 6 highly determines the photovoltaic performance of all-inorganic CsPbBr 3 perovskite solar cells (PSCs). Herein, the preferred phase conversion from precursor to Cs-Pb-Br derivatives is revealed by theoretically calculating the Gibbs free energies (∆ G ) of various phase conversion processes, allowing for a simplified multi-step solution-processable spin-coating method to hinder the formation of detrimental 0D Cs 4 PbBr 6 phase and enhance the photovoltaic performance of a PSC because of its large exciton binding energy, which is regarded as a recombination center. By further accelerating the interfacial charge extraction with a novel 2D transition metal dichalcogenide ReSe 2 , the hole-free CsPbBr 3 PSC achieves a champion efficiency of 10.67% with an impressive open-circuit voltage of 1.622 V and an excellent long-term stability. This work provides an in-depth understanding on the precise Cs-Pb-Br perovskite phase control and the effect of derivatives on photovoltaic performance of advanced CsPbBr 3 PSCs.

To enable fast sodium ion battery charging in a wide temperature range, the local structures of anode materials must be optimized to reduce the Na + diffusion resistance at the interface and inside the electrode. Guided by theoretical predictions, isotropic ReSe 2 with a 1 T phase crystal structure (1 T ReSe 2 ) is developed herein to exhibit enhanced electrical conductivity for efficient charge transfer compared to the 1 T' ReSe 2 phase. Enabled by its metallic characteristic and longer Re─Se bonds, 1 T ReSe 2 achieves a lower Na + diffusion barrier and lower adsorption energy than 1 T' ReSe 2 , facilitating faster Na + storage reaction kinetics. Operando spectroscopy characterization confirms that the 1 T ReSe 2 electrode can directly produce Na x ReSe 2 without undergoing a significant phase transition. This inhibits volume expansion, leading to improved cycling stability. As a result, 1 T ReSe 2 exhibits good fast-charging performance in a wide temperature range. A capacity of 197 mAh g −1 @20 A g −1 is maintained after 8000 cycles at room temperature, and a capacity of 136 mAh g −1 @1 A g −1 (corresponding to a capacity retention rate of 60%) is retained after 465 cycles at −40°C.

Topological insulators (TIs) hold considerable promise for the advancement of optoelectronic technologies, including spectroscopy, imaging, and communication, owing to their remarkable optical and electrical characteristics. This study proposes a novel combination of Bi2Se3TIs and ReSe2for self-powered broadband photodetectors with high sensitivity and fast response time. The Bi2Se3/ReSe2heterojunction photodetector achieves broadband response spectra ranging for 375 nm to 1μm. It demonstrates a significant responsivity of 64 mA/W at a wavelength of 600 nm (1 mW/cm2), exhibits a rapid response speed of 345μs rise/336μs fall time, and has a 3 dB bandwidth of 1.4 kHz under zero-bias conditions. The high performance can be attributed to the suitable energy band structure of Bi2Se3/ReSe2and high carrier mobility in surface states of Bi2Se3. Excitingly, self-powered TIs photodetectors allow for high-quality signal transmission. The TIs employed in photodetectors can stimulate the production of new optoelectronic features, but they could also be used for highly integrated photonic circuits in the future.

Rhenium diselenide (ReSe2) has attracted great interest due to its unique anisotropic structure and unusual in-plane anisotropic electrical and optical properties. However, efficient fabrication of large-area and high-quality 2D ReSe2 continuous films has become an increasingly important challenge. In this work, centimeter-scale 2D ReSe2 continuous films with the layer number varying from monolayer to 12 layers were successfully grown on a mica substrate using our space-confined CVD system via changing the position of the substrate. The fluorescence quenching effect and surface enhanced Raman scattering (SERS) effect on 2D ReSe2 films with different layer numbers were investigated using rhodamine 6G (R6G) dye molecules as a Raman probe. The large-area ReSe2 films show the layer-number-dependent nature of the SERS effect and a robust suppression effect of fluorescence. Our work explores the practical application of 2D ReSe2 films for molecular detection via the SERS technique.

Recently two-dimensional (2D) nanomaterials-mediated photothermal therapy (PTT) has become an important tool for treating cancer. However, visually monitoring the localization of nanoagents in cancer cells remains a key challenge. Herein, exploring high photostability, and high biocompatibility probes for monitoring PTT are still highly desirable. In this study, a novel optical probe named PEG@ReSe 2 nanosheets (polyethylene glycol, PEG; rhenium diselenide, ReSe 2 ) was prepared and employed to perform in vivo two-photon imaging for monitoring PTT in esophageal cancer cells. Under the illumination of a near-infrared (NIR) femtosecond laser at 820 nm with the output power as low as 5 mW, the PEG@ReSe 2 nanosheets showed significant two-photon features, producing a significant photoluminescence emission band at 637 nm. In addition, the prepared PEG@ReSe 2 nanosheets exhibited high resistance to photobleaching. Also, the PEG@ReSe 2 nanosheets showed low cytotoxicity for cancer cells, providing a high viability of more than 90%. More importantly, the PEG@ReSe 2 nanosheets could enter cancer cells and work as a two-photon probe for visually displaying the PTT process. After 12 h incubation, the PEG@ReSe 2 nanosheets produced strong two-photon signals in KYSE150 cancer cells, enabling them to perform in vivo bi-channel bioimaging. In light of its photothermal effects, the PEG@ReSe 2 nanosheets also could serve as a sensor for monitoring PTT under low-power infrared laser irradiation. This study suggests that, the PEG@ReSe 2 nanosheets could serve as a superior two-photon biosensor for monitoring the PTT process in cancer nanomedicine.
