Synergic antimony–niobium pentoxide nanomeshes are fabricated on a large scaleviathe controllable decomposition of SbNbO4nanosheets, which are obtained from ultrathin hydrated niobium oxide (Nb2O5·nH2O) layers. Synergizing the merits of highly active Sb and structurally stable Nb2O5, the nanomeshes exhibit enhanced charge-transfer kinetics, thus leading to a high capacity and good high-rate performance for sodium storage.

Bulbous structures consisting of meristematic clumps (designated “shoot primordia”) were induced from a meristematic culture of a hybrid statice (Limonium altaica Mill. × L. caspium Mill., cv. Blue Symphonet). The shoot tips were cultured in 25 mL of liquid 1/2 Murashige & Skoog (MS) medium supplemented with 0.44 μm BA and 0.054 μm NAA and 3% sucrose at pH 5.8 by vertically shaking at 2 rpm on rotating stages (1 m in diameter) at 25 °C. One month after inoculation of shoot tips, numerous small globular structures were formed and propagated vegetatively at a high rate following subculture. Segments of shoot primordia had developed into plantlets 2 weeks after transfer to solidified 1/2 MS medium supplemented with 0.44 μm BA and 1% sucrose. Plantlets successfully acclimated and grew into normal plants in a greenhouse. Cold-hardened, precultured small segments of shoot primordia were successfully cryopreserved in liquid N by vitrification. Vitrified and warmed segments plated on solidified 1/2 MS medium produced shoots about 21 d after plating. Cultured masses of shoot primordia appear promising for large-scale production and cryopreservation of annual and biennial statice. Chemical names used: 6-benzyladenine (BA); 1-naphthaleneacetic acid (NAA).

Spinel lithium titanate ( Li4Ti5O12 ), shown to be a superior anode material for energy storage battery, has attracted a great deal of attention because of the excellent Li-ion insertion and extraction reversibility. The high rate characteristics must be amplified before large scale production. A method to overcome this is to prepare electrode materials coated with carbon. A Li4Ti5O12 /Polyacene (PAS) composite were first prepared via an in situ carbonization of phenol-formaldehyde (PF) resin route using TiO2 -anatase, Li2CO3 , and PF resin as precursors by a solid-state reaction. With increasing the current density, the sample still keeps the excellent cycle performance.

The literature on female labour in Third World countries has become quite extensive. India, being comparatively more advanced industrially, and in view of its size and population, presents a pictures of multiplicity of problems which face the female labour market. However, the author has also included Mexico in this analytical study. It is interesting to see the characteristics of developing industrialisation in two different societies: the Indian society, which is conservative, and the Mexican society, which is progressive. In the first chapter of the book, the author explains that he is not concerned with the process of industrialisation and female labour employed at different levels of work, but that he is interested in forms of production and women's employment in large-scale production, petty commodity production, marginal small production, and self-employment in the informal sector. It is only by analysis of these forms that the picture of females having a lower status is understood in its social and political setting.

Aim and Objective: Itopride is a prokinetic agent used for treating conditions like non-ulcer dyspepsia. Itopride is administered as its hydrochloride salt. Trimethobenzamide is used for treating nausea and vomiting and administered as its hydrochloride salt. The aim is to develop a novel and environmental friendly method for large-scale production of itopride and trimethobenzamide. Materials and Methods: Itopride and trimethobenzamide can be prepared from a common intermediate 4- (dimethylaminoethoxy) benzyl amine. The intermediate is prepared from one pot synthesis using Phyrdroxybenzaldehye and zinc dust and further reaction of the intermediate with substituted methoxy benzoic acid along with boric acid and PEG gives itopride and trimethobenzamide. Results: The intermediate 4-(dimethylaminoethoxy) benzylamine is prepared by treating p-hydroxybenzaldehyde and 2-dimethylaminoethyl chloride. The aldehyde formed is treated with hydroxylamine hydrochloride. The intermediate is confirmed by NMR and the purity is analysed by HPLC. Conclusion: Both itopride and trimethobenzamide were successfully synthesized by this method. The developed method is environmental friendly, economical for large-scale production with good yield and purity.

Cyanobacteria are photosynthetic prokaryotic organisms which represent a significant source of novel, bioactive, secondary metabolites, and they are also considered an abundant source of bioactive compounds/drugs, such as dolastatin, cryptophycin 1, curacin toyocamycin, phytoalexin, cyanovirin-N and phycocyanin. Some of these compounds have displayed promising results in successful Phase I, II, III and IV clinical trials. Additionally, the cyanobacterial compounds applied to medical research have demonstrated an exciting future with great potential to be developed into new medicines. Most of these compounds have exhibited strong pharmacological activities, including neurotoxicity, cytotoxicity and antiviral activity against HCMV, HSV-1, HHV-6 and HIV-1, so these metabolites could be promising candidates for COVID-19 treatment. Therefore, the effective large-scale production of natural marine products through synthesis is important for resolving the existing issues associated with chemical isolation, including small yields, and may be necessary to better investigate their biological activities. Herein, we highlight the total synthesized and stereochemical determinations of the cyanobacterial bioactive compounds. Furthermore, this review primarily focuses on the biotechnological applications of cyanobacteria, including applications as cosmetics, food supplements, and the nanobiotechnological applications of cyanobacterial bioactive compounds in potential medicinal applications for various human diseases are discussed.
