Summary: In this research, CdS nanoparticle-doped metal-organic frameworks (CdS@DUT-52) with different contents were synthesized using a solvothermal method. UV-vis spectroscopy and photoelectrochemical testing proved that CdS@DUT-52 possesses strong light absorption ability and effective electron-hole separation properties. CdS@DUT-52 was used to trigger the photooxidation of amines, sulfides, and alcohols in the presence of air or oxygen, resulting in considerable yields of corresponding imines, sulfoxides, and aldehydes compared to a single component.

Summary: Simultaneously utilizing photogenerated electrons and holes to convert renewable biomass and its derivatives into value-added products and hydrogen (H-2) is a promising strategy. In this study, a facile hydrothermal method is used to construct a direct Z-scheme CdS/WO3 binary composite for photocatalytic coupled redox reaction, producing H-2 and selectively converting aromatic alcohols into aromatic aldehydes in one pot. The CdS/WO3 binary composite exhibits significantly enhanced performance compared to bare CdS and WO3, attributed to its extended light harvesting range, efficient charge carrier separation rate, and optimized redox capability. The feasibility of converting various aromatic alcohols to aldehydes coupled with H-2 evolution on the CdS/WO3 photocatalyst is demonstrated, along with a proposed reaction mechanism.

Summary: Efficient utilization of hot charge carriers is essential for semiconductor-based optoelectronic devices. In this study, a one-dimensional/two-dimensional heterojunction of CdS/MoS2 nanorod/nanosheet composite was fabricated to investigate the migration behavior of hot charge carriers. The results showed that hot carriers in the high energy states of CdS preferentially migrated into the higher energy states of MoS2, rather than being cooled to the band edge. Additionally, higher energy pump photons were found to be more efficient in the hot carrier transfer process, leading to an extended charge carrier separation.

Summary: We demonstrate the scattering of laser light from two InAs quantum dots coupled to a photonic crystal waveguide by strain-tuning the optical transitions of the dots into mutual resonance. The nonlinearity is enhanced by scattering laser light from two dots, providing a means of manipulating few-photon optical nonlinearities. This approach also establishes opportunities for multiemitter quantum optics in a solid-state platform.

Summary: A highly dispersed Ni catalyst supported by mesoporous SiO2 nanospheres and promoted by alkaline MgO was synthesized and used as an active and stable catalyst for dry reforming of methane (DRM). The Ni/MgO-mSiO(2) catalyst showed superior performance compared to similar catalysts in literatures, with stable CH4 and CO2 conversions around 82% and 85% during 120 hours of DRM reaction. The promotion effect of MgO on the Ni catalyst was systematically studied and found to enhance the dispersion of active centers, inhibit sintering and deactivation of Ni, and facilitate the cracking of CH4, activation of CO2, and elimination of carbon deposits.

Summary: In the industry, designing synergetic functional nanocatalysts is a desirable strategy to achieve both high activity and selectivity for CO2 hydrogenation. In this study, bicomponent tandem catalysts ZnZrOx/SAPO-34@UIO-n were fabricated to catalyze CO2 conversion into light olefins. The monodispersed SAPO-34 zeolites were used as the core for the growth of the UIO-n shell, resulting in the membrane-encapsulated nanocrystal SAPO-34@UIO-n. By mixing it with ZnZrOx, the ZnZrOx/SAPO-34@UIO-n catalyst was obtained. The presence of stable UIO-n membrane in the bifunctional catalyst adjusted the conversion of CO2 hydrogenation products from paraffins to olefins.

Summary: Photonic crystal patterns with angle-dependent colors are a promising anti-counterfeiting material. Delicate PC patterns can be fabricated by silkscreen printing of photo-curable SiO2/monomer PC inks on the substrate, followed by UV irradiation to fix the PC structures. The resulting PC marks show noticeable angle effects, uniform color distribution, and good mechanical and chemical stabilities. Different silk screen stencils are investigated to achieve the best color intensity and printing resolution. As a demonstration of their anti-counterfeiting functions, the PC patterns exhibit color changes and reversible switches under different angles.

Summary: This study reports a method of fabricating an electrically responsive photonic crystal (ERPC) in weak polar media. The ERPC shows good performance due to less screening of Coulombic interaction. By using aniline as a weak polar solvent, the ERPC is fabricated without any charge-controlling agent. The resulting SiO2/ANI ERPC exhibits a broad reflection wavelength tuning range (230 nm) and a low working potential (1.4 V), leading to improved stability and reversibility of the electrical tuning.
