Single-phase novel Cs3Bi2I9 colloidal perovskite nanocrystal synthesis was successfully developed and optimized by adopting different synthetic conditions with varied experimental parameters, viz., the stoichiometric ratio of precursor compounds, growth temperature,...

Herein, we report cellulose-based threads from Indian sacred Lotus ( Nelumbo nucifera ) of the Nymphaceae family embellished with MoS 2 nanosheets for its enhanced hydrophobic and antimicrobial properties. MoS 2 nanosheets synthesized by a coprecipitation method using sodium molybdate dihydrate (Na 2 MoO 4 ·2H 2 O) and thioacetamide (CH 3 CSNH 2 ) were used as a sourse for MoS 2 particle growth with cellulose threads extracted from lotus peduncles. The size, crystallinity, and morphology of pure and MoS 2 -coated fibers were studied using X-ray diffractometry (XRD) and scanning electron microscopy (SEM). the XRD pattern of pure lotus threads showed a semicrystalline nature, and the threads@MoS 2 composite showed more crystallinity than the pure threads. SEM depicts that pure lotus threads possess a smooth surface, and the MoS 2 nanosheets growth can be easily identified on the threads@MoS 2 . Further, the presence of MoS 2 nanosheets on threads was confirmed with EDX elemental analysis. Antimicrobial studies with Escherichia coli and Candida albicans reveal that threads@MoS 2 have better resistance than its counterpart, i.e., pure threads. MoS 2 sheets play a predominant role in restricting the wicking capability of the pure threads due to their enhanced hydrophobic property. The water absorbency assay denotes the absorption rate of threads@MoS 2 to 80%, and threads@MoS 2 shows no penetration for the observed 60 min, thus confirming its wicking restriction. The contact angle for threads@MoS 2 is 128°, indicating its improved hydrophobicity.

Smooth surface and periodic size control synthesis of BiVO4 semiconducting particles were achieved under hydrothermal conditions with long carbon chain oleic acid as an additive in weak organic acid and...
