Summary: A systematic investigation into the hydrothermal synthesis and characterization of copper selenides (CuSe) reveals that CuSe2, CuSe, and Cu2Se can be synthesized at a relatively low temperature and within a limited time frame by controlling the feeding ratio of Cu and Se precursors and reducing agent. The crystal growth and morphology of the compounds significantly affect their electrical conductivity, Seebeck coefficient, and thermoelectric properties. Additionally, the synthesized Cu-Se compounds exhibit promising photothermal conversion characteristics, which can be utilized for enhanced energy harvesting in thermoelectric modules under light exposure.

Summary: The construction of ultrathin porous nitrogen-doped carbon coated stoichiometric copper selenide heterostructures (CuSe/NC) for multi-modal cancer therapy is challenging. These nanoplatforms can achieve both photothermal therapy (PTT) and photocatalytic therapy (PCT) under a single near-infrared (NIR) light, and can be loaded with doxorubicin (DOX) and DNA to enable smart release for precise chemotherapy. In vitro and in vivo studies confirm the excellent anticancer efficacy and negligible toxicity of CuSe/NC-DOX-DNA nanoplatform, providing a paradigm for combination cancer therapy.

Summary: The addition of nanoparticles decreases the transmittance of nano-enhanced paraffin while a small rise in transmittance occurs with temperature increment. ZnO and CuO nanoparticles can improve the thermal conductivity of nano-enhanced paraffin. CuO/paraffin can absorb more solar energy, and the optimal photothermal performance can be achieved by adjusting the nanoparticle volume fraction.

Summary: By doping S and Te, the electronic band structure of the second phase is adjusted, resulting in high carrier mobility and power factor in Cu2Se-based composite materials. The dispersed second-phase Cu2Se0.88S0.06Te0.06, dislocations, and nanograins were observed, leading to a substantial reduction in the thermal conductivity. High figure of merit (zT) values of 2.04 (by Dulong-Petit heat capacity) and 2.34 (by Differential Scanning Calorimetry (DSC) measured heat capacity) were achieved at 850 K, which are 65% higher than that of Cu2Se in this work and comparable to the recently reported p-type Cu2Se with outstanding performance.

Summary: Even small changes in physicochemical properties of nanoforms (NFs) can influence their environmental fate and hazard. Testing and characterizing each individual NF will not be feasible due to the large number of new materials being developed. Targeting the most relevant form of the NF for a given exposure is important for efficient risk assessment. In aquatic systems, functional fate processes play a key role in determining the exposure relevant form of NFs. Grouping of NFs and read-across based on functional fate pathways can be justified by considering the shared fate and hazard profile. A new Integrated Approaches to Testing and Assessment (IATA) is presented, focusing on dissolution, dispersion stability, chemical transformations, and the contribution to toxicity from particles and dissolved components. This IATA can be used as a template for future in vivo kinetic assessments.

Summary: Compared with vein injection, oral administration is a preferred non-invasive and self-help treatment option for cancer therapy. However, the harsh gastrointestinal tract and biological barriers limit the stability and efficiency of oral drug delivery systems. To overcome these challenges, researchers have developed Cyssome, a drug delivery platform that can maintain stability in harsh environments, penetrate biological barriers, and improve drug release and bioavailability.
