Summary: This study proposed a novel microflow system that cascades immobilized enzyme catalysis and photocatalysis for the green synthesis of 2-phenylbenzothiazole. By achieving over 99% product yield and retaining over 93.7% of catalytic activity, it provides a potential foundation for industrial green production of 2-PBZ, overcoming limitations of traditional approaches.

Summary: A temperature-controlled intermolecular [3 + 2] annulation of N,N-disubstituted arylhydrazines with CS2 in the presence of DMSO has been developed for facile access to benzo[d]thiazole-2(3H)-thiones and benzo[d]thiazol-2(3H)-ones. This direct C-S/C-N bond formation reaction does not require any external catalysts, transition metals, bases, ligands, and oxidants, offering high step economy.

Summary: This paper investigates the adsorption behavior of MBT onto chalcocite at different electrochemical potentials using SHINERS. The results show that adsorption is less favorable at negative potentials and can even be completely inhibited. The authors propose a cathodic passivating process and the formation of a passivation layer as the reasons for the prevention of adsorption after potentials switch back to positive. This study suggests that electrochemical controlled flotation can enhance the separation efficiency of chalcocite.

Summary: This study investigated the effect of an ultralow content of MoS2 two-dimensional particles on the photodegradation mechanism of PS. Accelerated weathering experiments were conducted on neat PS and its nanocomposites with different MoS2 contents, showing that the degradation reactions were slowed down with higher MoS2 contents (>0.003%). FTIR and UV/Vis spectroscopy results indicated that the presence of MoS2 particles did not alter the PS degradation mechanism. SEC results demonstrated the stabilizer effect of MoS2 particles, with the Mn, Mw, and Mw/Mn values being less modified compared to neat PS after 8 weeks. MoS2 acted as a UV stabilizer by deactivating the free radicals generated by the PS matrix, even at a low filler amount (<0.005 wt%).

Summary: Photocatalysis technology, particularly using MoS2-based materials, is considered as the greenest route for degrading and mineralizing organic pollutants due to its high efficiency and environment-friendliness. The broad application prospect of MoS2-based materials in the photocatalytic degradation of environmental pollutants is highlighted in recent research.

Summary: In this study, economic and practical strategies were developed to synthesize 3-benzyl-/3-benzyl-2-phenyl-benzo[4,5]imidazo[2,1-b]thiazoles via direct nucleophilic attack/addition cyclization and C-H bond activation reactions. The optimized reaction conditions allowed for the tolerance of various electron-donating and electron-withdrawing groups, resulting in new benzo[4,5]imidazo[2,1-b]thiazoles with good to excellent yields (up to 93% yield).

Summary: This paper focuses on developing a reliable mathematical model for industrial batch MBT production process, using a series of differential and algebraic equations. Due to limited industrial/experimental data, a reduced estimable parameter set is derived and a multiple-starting-point strategy is applied to solve the non-convex parameter estimation problem. The proposed model shows promising prediction performance with independent test data, validated by a cross-validation technique.

Summary: This study investigated the effects of water on a 2-mercaptobenzothiazole film pre-formed on copper at low pressure and room temperature using X-ray photoelectron spectroscopy. The results showed that exposure to water vapor led to desorption of 2-MBT molecules not directly bonded to copper, with cleavage of the bond between exocyclic sulphur and copper, while nitrogen remained bonded to copper.

Summary: This study focuses on the degradation of emerging pollutants (EPs) using recombinant bacterial peroxidases called DyPs. Results show that some DyPs have the potential to effectively degrade EPs, while others are less effective. The role of redox mediators in EP degradation by DyPs was also examined, revealing significant improvement in the degradation process. Additionally, a detailed analysis of degradation products was conducted for one of the DyPs, providing insights into the breakdown process.

Summary: In this study, a combination accelerator system was developed to enhance the vulcanizing activity of 2-mercapto benzothiazole (MBT) with different nitrosamine-safe thiuram disulfides (TDs). The results showed that the novel TDs combined with MBT significantly improved the curing characteristics and mechanical properties, with smaller molecular size and higher basicity TDs showing better effects.
