Summary: This paper aims to identify the interaction mechanism between CO2 and chemical sensors based on Gd-doped SnO2, SnO2, and Gd2O3 powders. The presence of humidity can offset the low reactivity of CO2. Gd concentration was varied to determine the limit for Gd integration as a doping ion. The change in electrical resistance is influenced by the density of oxygen vacancies or compensation for opposite behaviors in the SnO2-Gd2O3 nanocomposite structure. CO2 exposure to humidity leads to specific chemical interactions on the surfaces of SnO2 and Gd2O3.

Summary: Recent observations have shown that a few drops of water on the surface of oxide materials can generate eco-friendly and cost-effective electricity, known as a hydroelectric cell (HEC). The production cost of HEC is very low, and porous SnO2 samples prepared by solid-state sintering have been shown to be effective for HEC. Various analyses such as X-ray diffraction, SEM, and Barrett-Joyner-Halenda technique were used to study the properties of the samples. Peal current and voltage values were obtained for circular and square pellets, demonstrating the dissociation of water and conduction phenomenon in the samples.

Summary: This study investigates the effect of vacuum level on laser induced white emission (LIWE) of graphene foam and compares it with the electric incandescence of tungsten wire. The increase in pressure inside the dynamic vacuum chamber reduces the emission intensity of LIWE, while it has no effect on the emission of the electrically driven tungsten wire. A similar dependency is observed in the case of field emission (FE) of carbon cathodes. This analogy confirms that white emission and FE are coincident processes occurring during laser excitation of graphene foam.

Summary: Novel Sn/reduced graphene oxide/carbon nanofibers ternary hybrids were synthesized via one-step synthesis process. Sn nanoparticles were uniformly sandwiched in reduced graphene oxide layers and had good contact with carbon nanofibers. The ternary hybrids showed superior lithium storage performance compared to the binary hybrids of Sn/reduced graphene oxide and Sn/carbon nanofibers. After 90 cycles, the reversible capacity of the ternary hybrids reached 643 mAh g-1. Importantly, electrochemical impedance spectroscopy measurements confirmed the effective reduction of charge transfer resistance through the integration of Sn, reduced graphene oxide, and carbon nanofibers.

Summary: It is demonstrated that metal oxyhydroxides generated through surface reconfiguration during electrochemical processes can provide extra capacity besides the oxygen-anion intercalation in perovskite oxides. The strong Jahn-Teller distortion of Co2+ and Ni3+ in the pseudo trigonal prisms for the 2H-perovskite structure helps the formation of metal oxyhydroxides on the surface of the pristine material. Among the three 2H-perovskite related oxides, Sr5Co3NiO12-x with the highest Co2+ and Ni3+ contents exhibited the highest capacity increase. This study offers a promising pathway for the development of advanced perovskite-like oxide pseudocapacitive materials.

Summary: UV-charged optical stimulated single-band phosphors are commonly used for single-level optical data storage. However, UV-visible-NIR rechargeable optical stimulated double-band phosphors are urgently needed for multiplexed high-throughput optical data storage. In this study, the authors designed and synthesized a Mn2+,Cr3+ co-doped zinc gallate phosphor that exhibits strong red-green bicolor persistent luminescence (PersL) and can be charged by visible and NIR light. The temperature-dependent intensity of red and green PersL, along with the mechanism based on different trap types and filling approaches, are proposed. This phosphor shows great potential for wavelength multiplexing in optical data storage.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
