Micelle-Assisted Lewis and Brønsted Acid Catalysis: A Review Towards Greener and Efficient Synthesis of Polycyclic and Heteroaromatic Compounds Harvinder S. Sohal, Sanyojak Kanwal, Chirag G. Makvana, Navneet Kaur, Haesook Han, et al. Molecules, 2026 Considering the expanded interest in reducing organic solvents in synthesis, surfactants and surfactant-based catalysis have been used to carry out various organic transformations in water. In recent years, the integration of Lewis and Brønsted acid catalysis with micellar systems has gained considerable attention as a powerful approach to enhance reaction efficiency while minimizing the environmental impact of synthetic processes. In this article, we depict the most recent advances in the water-interceded synthesis of different organic systems by utilizing different surfactant-type catalysts, which are important structural motifs in pharmaceuticals, agrochemicals and functional materials. Further, these methods incorporate green reaction media, mild reaction conditions, and a great yield of product with high purity in a shorter interval of time. Understanding the scope and impact of this area, authors have made efforts to collect and compile the data that indicates many named reactions, such as Friedlander annulation, aldol condensation, the Biginelli reaction, the Mannich reaction, Suzuki–Miyaura cross-coupling, etc., now take place using surfactant-based catalysts.
Structural and morphological insights of cadmium sulphide nanoparticles for photosynthesis and antibacterial applications Amika, Dinesh Kumar, Bhawna, Deepak Kumar, Kulwinder Singh, et al. Advances in Natural Sciences Nanoscience and Nanotechnology, 2026 Development of an effective photocatalysts is a crucial for the enhancement of water splitting process. Cadmium sulphide (CdS) is a novel material, acts as a visible light active photocatalyst useful for photocatalytic water splitting. In present work, CdS nanoparticles (NPs) have been synthesized by hydrothermal method. Synthesized samples were characterized using different techniques such as XRD, FTIR, SEM and DRS-UV. XRD results revealed the hexagonal crystal structure of CdS NPs with an average crystallite size of ∼14 nm. FTIR analysis showed IR peaks at 1636, 1378 and 1007 cm −1 correspond to stretching vibrations of C–N bond. The vibrational bands obtained at 790 and 580 cm −1 confirms the fingerprint region thereby, revealing the development of CdS. Morphological analysis showed the formation of spherical NPs and agglomeration occurrence due to high surface energy. Optical analysis inferred that absorption edge lies in visible region with band gap value of 2.40 eV. Furthermore, photocatalytic water splitting experiments were performed showing hydrogen production rate of 163.4 and 289.5 μmol h −1 g −1 for bare CdS and in the presence of sacrificial agent (N 2 S) respectively. The structure and activity retention were confirmed by XRD after stability testing during two hydrogen evolution cycles. Further, antibacterial activity of synthesized nanoparticles was assessed by using Staphylococcus aureus (MTCC-3160), and Escherichia coli (MTCC-1302) which displays good Zone of Inhibition.
Insights of micro-structural, optical, morphological, thermal, compositional and theoretical properties of SnS2nanostructures Sawini, Kulwinder Singh, Abhishek Kumar, Shagun Nag Physica Scripta, 2025 In recent years, tin disulfide (SnS2) nanostructures have possessed substantial research interest due to tunable characteristics including crystallographic, emission, linear as well as non-linear optical parameters and their theoretical aspects etc. In present work, two-dimensional SnS2 nanostructures were synthesized through simple hydrothermal method. Structural analysis signifies the formation of hexagonal phase (space group symmetry: P63mc). Raman and FTIR spectroscopy techniques also revealed the formation of hexagonal phase and presence of Sn-S and S-S stretching vibrational modes in the prepared SnS2 nanostructures respectively. Morphological and elemental analysis inferred that synthesized nanostructures exhibit a hexagonal sheet like morphology and uniform Sn and S elemental distribution. XPS analysis also indicated the presence of individual elements i.e. Sn and S in +4 and −2 energy states in the synthesized nanostructures. Furthermore, the stability of prepared SnS2 nanostructures have been revealed by TGA analysis. Density functional theory (DFT) studies such as phonon dispersion curves as well as projected density of states signifies the stability of the SnS2 layered structure. Photoluminescence results revealed the emission in visible region i.e. ∼469, ∼566 and ∼603 nm. Ultraviolet -visible spectroscopic results inferred that the reflectance edge lies in visible spectrum with band gap value of ∼2.30 eV. Numerous empirical models were also employed to investigate the linear along with non-linear optical parameters and discussed in detail.
