Summary: The widespread use of synthetic dyes can lead to the generation of colored wastewaters, which can cause serious environmental problems. This study establishes a novel biohybrid system for the light-driven degradation of dyes, specifically triphenylmethane dyes, using a non-photosynthetic microorganism C. thermocellum self-photosensitized with CdS nanoparticles. The biohybrids exhibit remarkable decolorization effects, and the catalytic activities can be enhanced by controlling the particle sizes of CdS semiconductors.

Summary: Highly luminescent GdVO4:Eu3+/carbon dots nanocomposite was synthesized by hydrothermal deposition method. The existence of citrate anions, ethylenediamine cations, and polymer-like CDs in the crude CDs solution promoted the growth of CDs on the surface of GVE and prevented nitrogen atoms from falling off during the deposition process. The dialyzed CDs solution resulted in fragile coated CDs during the hydrothermal deposition process.

Summary: Cadmium-based semiconductors are widely used in various applications such as light-emitting, energy conversion, photodetection, and artificial photosynthesis. Recycling the element from Cd-based semiconductors is necessary due to concerns about potential toxicity. CdS precipitation is commonly used, but it can easily oxidize and release into the environment, causing accumulation in the food chain. This study presents a facile room temperature method for recycling Cd from CdS, using a lithium-ethylenediamine solution, with a total recovery efficiency of 88%.

Summary: Material modification with low surface energy can achieve lower surface free energy on micro-and nano-rough structures, which is crucial for developing superhydrophobic surfaces. In this study, attapulgite (APT) was modified with alkylamine, alkylammonium salt, and stearic acid, and the interaction between low surface materials and attapulgite was explained. The results showed that the hydrophobicity of APT was significantly modified by the modifiers, and the surface free energy of the composites first decreased and then increased with increasing molecular number of low surface energy monomers.
