Summary: Compared with traditional hydrothermal synthesis, microwave-assisted synthesis offers the advantage of faster and more energy efficient synthesis. In this study, the microwave-assisted hydrothermal method was used to synthesize MoS2/BiVO4 hetero-junction photocatalyst, resulting in a spherical structure in the nanorange. The heterojunction significantly improved the photocatalytic performance, with a degradation rate of tetracycline hydrochloride (TC) of 93.7% in 90 min. The active species capture experiments indicated that ·OH, ·O-2(-) and h(+) active species played a major role in the degradation of TC. Microwave technology provides a quick and efficient method for synthesizing MoS2/BiVO4 heterojunction photocatalysts.

Summary: This study describes a pioneering method of microwave-assisted reflux synthesis of W-BiVO4, which allows for the preparation of efficient photocatalysts in a short period of time. Tungsten doping and control of the structure and morphology of the mixture play an important role in the photocatalytic performance, while the addition of PVP helps to control the morphology. However, adding PVP may result in lower material efficiency.

Summary: In this study, a simulated sunlight driven 2D/2D HSr2Nb3O10/WO3 composite was developed with remarkable photocatalytic activities for degrading methyl orange. The preparation of HSr2Nb3O10/WO3 composites by planetary ball milling and the synthesis of ultrathin HSr2Nb3O10 nanosheets using microwave irradiation significantly reduced the preparation time. The heterojunction interaction between HSr2Nb3O10 and WO3 led to enhanced photocurrents and photocatalytic activity, with a proposed Z-Scheme photocatalytic mechanism based on theory and radical species trapping experiments.

Summary: Nanostructured SnS was synthesized using a facile microwave-assisted method, and its photocatalytic activity for degrading methylene blue under visible light was evaluated. The SnS showed high efficiency in degrading the pollutant, attributed to its high specific surface area. The adsorption process was described by the Fritz-Schlunder and Baudu models, and the pseudo-second-order adsorption kinetic model showed good agreement with experimental data. The electronic and structural properties of SnS were analyzed using density functional theory, confirming its non-magnetic property.

Summary: A fast microwave-assisted method was used to grow zinc oxide under different pH conditions, resulting in materials with varying crystallinity, morphology, and thermal stability. The obtained zinc oxide materials showed good photodegradation and mineralisation efficiency of the model organic pollutant, 4-chlorophenol, in the UV light range. The kinetics of the photocatalytic degradation of 4-chlorophenol were determined based on a pseudo-first-order model, assuming the Langmuir-Hinshelwood mechanism.

Summary: This study investigates the promotion effect of microwave-absorbing photocatalysts on the photocatalytic oxidation process. The results show that the thermal effect of the microwave field enhances the separation efficiency of photogenerated electrons and holes, while the athermal effect improves the light absorption rate of the catalyst and promotes the generation of reactive oxygen radicals. These findings provide a theoretical foundation for practical applications.

Summary: The biggest challenges in modern society revolve around the production and storage of affordable, clean energy. Recent research has focused on discovering new electrode materials to enhance energy production and storage. In this study, nitrogen-implanted carbon particles were synthesized for the first time from Acorus Calamus for use in symmetric supercapacitors. The carbon particles activated with KOH at 750 degrees C (C-750) under a nitrogen atmosphere exhibited superior structural, textural, morphological, and electrochemical performance. BET analysis confirmed that the C-750 carbon nanoparticles significantly increased the surface area to about 3551.07 m(2)/g. Further analysis revealed a pore size of 3.70 nm and a pore volume of 0.51 cc/g. The high surface area and mesoporous nature of the C-750 sample effectively enhanced the specific capacitance to 354.44 Fg(-1) at 1 Ag-1 using a 6 M KOH electrolytic solution. Additionally, the energy density and power density of the C-750 sample were observed to be approximately 47.2 Whkg(-1) and 16,000 Wkg(-1), respectively.

Summary: The dynamics of a Brownian particle in Morse potential under thermal fluctuations is investigated by numerically integrating the corresponding Langevin equation. The dependence of Kramer's rate on temperature and viscosity of the medium is studied by mean first passage time. An approximate analytical expression for the rate constant is found and it shows a temperature dependent pre-factor for the Arrhenius equation. Numerical simulations are consistent with the analytical approximations.

Summary: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

Summary: The phenomenon of ribbon lengthening in PV modules exposed to thermal cycling is not well explained in the literature. In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.

Optical absorption mechanisms in qNL arrays were investigated using near-field scanning optical microscopy (NSOM), revealing that the enhancement is a result of the combination of effective antireflection coating, increased optical interactions between adjacent dielectrics for elevated light trapping, and strong light concentration due to the presence of qNLs.
