Summary: This study presents a visible-light-driven organic-inorganic S-scheme heterostructure photocatalyst with excellent performance in removing antibiotics from wastewater. By anchoring TCPP on the surface of Bi12O17Cl2, the S-scheme junction between TCPP and Bi12O17Cl2 was created, enhancing the visible-light response and accelerating the disintegration and conservation of photo-carriers. The resulting TCPP/Bi12O17Cl2 showed significantly improved photocatalytic activity and stability compared to Bi12O17Cl2. Through scavenging tests, LC-MS analysis, and toxicity calculation, the reactive radicals, degradation pathway, and eco-toxicity were elucidated. This research demonstrates the potential practicality of porphyrin-based S-scheme heterojunction photocatalysts for efficient antibiotic removal.

Summary: The size and intensity of the system of delocalized electrons are reflected in the form of the induced magnetic field. However, the significance of different-shaped metal nanoparticles in stagnant water undergoing convective heating is still unclear. Numerical calculations and analysis reveal that an increase in convective heating of the wall can enhance temperature distribution, regardless of whether it is a heat source or heat sink.

Summary: This study analyzes the dynamics of water colloidal mixtures with three different types of nanoparticles. The results show that increasing the density of spherical nanoparticles decreases friction and accumulation of species, but increases the mass transfer rate near the wall. Additionally, increased thermo-migration of nanoparticles decreases the Nusselt number, while increased Brownian motion decreases heat transfer and temperature distribution but increases mass transfer.

Summary: This study assessed the usage and effectiveness of common charge referencing methodologies for insulating samples in X-ray photoelectron spectroscopy (XPS) results. It was found that using adventitious carbon (AdC) as a charge reference gave satisfactory and meaningful results in 95% of the cases assessed. Electrical isolation of mixed insulating/semi-conducting/conducting samples was also shown to significantly improve outcomes.

Summary: Transition metal disulfides, such as MoS2 and WS2, have the potential to be efficient catalysts for hydrogen evolution reaction. However, their practical application is hindered by issues like inert basic plane and low electrical conductivity. To overcome these limitations, we have constructed a heterojunction of MoS2/WS2 and doped it with transition metal elements (Pt and Pd). Our results show that the Pt-doped heterojunction (Pt@MoS2/Pt@WS2) exhibits high catalytic activity for hydrogen evolution, with a low energy barrier. This enhanced performance can be attributed to the unique heterostructure, narrowed band gap, new impurity levels, and charge distribution characteristics of the heterojunction.

Summary: This paper focuses on the improvement of electrochemical performance of supercapacitors with high-energy storage by selective electrode materials and rational structural design. The Ti3C2/CNTs/MnCo2S4 composite electrodes were fabricated, which exhibited enhanced specific capacitance, high rate retention, and excellent cycling stability. These improved electrochemical performances were attributed to the synergistic effect of pseudocapative material of MnCo2S4, remarkable conductivity of Ti3C2 and CNTs, and the micro-/nano-porous structures constructed by stacking Ti3C2 flakes with CNTs. The Ti3C2/CNTs/MnCo2S4 electrode-based symmetric supercapacitor also demonstrated a high energy density, indicating the substantial enhancement of Ti3C2-based supercapacitors by rational design and modification.

Summary: The effect of interlayer spacing on the catalytic properties of MoS2 has been systematically investigated. The expansion of interlayer spacing is found to enhance the catalytic hydrogen evolution of MoS2 under certain hydrogen coverages. Controllable tuning of the catalytic properties of MoS2 can be achieved by adjusting the interlayer spacing. The enhanced effect of interlayer expansion is attributed to the increased occupancy density of partially occupied antibonding orbitals near the Fermi level of Mo atoms, which enhances electron transfer.
