  • The method is successfully applied for ultrasensitive detection of trace amount benzophenone-type UV filters in environment water samples. It is indicated that the method has the advantages of rapid and efficient enrichment, high sensitivity, and excellent repeatability. Our study extends the application of core-shell mesoporous silica materials and would be of value for pretreatment of trace-amount and complex real samples.

  • The ontogeny of seed coat and endosperm tissue in Zygophyllum fabago L. was studied to determine their developmental importance using different histochemical and microscopic techniques. Our results revealed that the ovule of Z. fabago was of the anatropous and bitegmic type. The inner epidermis cells were retained up to the end of seed development, whereas the other layers were removed in the early stages. Moreover, the outer integument was changed into the seed coat sculptures during the seed development. Concurrently, multiple cytoplasmic strings were formed at the seed coat cells.

  • Solvent-based polyurethanes and poly(urethane-acrylate)s were synthesized using phosphorus-containing polyester polyols in order to compare the thermal properties of different polymer types. Since the location of the phosphorus group might have vital importance when comparing the thermal properties, phosphorus groups were kept on the pendant chains in poly(urethane-acrylate)s using phosphorus-containing urethane macromonomers while they were kept on the backbone in polyurethanes.

  • Pristine and WO3 decorated TiO2 nanorods (NRs) were synthesised to investigate n-n-type heterojunction gas sensing properties. TiO2 NRs were fabricated via hydrothermal method on fluorine-doped tin oxide coated glass (FTO) substrates. Then, tungsten was sputtered on the TiO2 NRs and thermally oxidised to obtain WO3 nanoparticles. The heterostructure was characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray (EDX) spectroscopy.

  • Hybrid paper sheets were prepared by applying a thin coating layer of cross-linked polydimethylsiloxane (PDMS) and inorganic particles onto Whatman Grade 1 filter paper substrates. Several coatings with different inorganic particle contents and types were applied onto the paper substrates to investigate the effect of the variation in the coating formulation on the (i) wetting, (ii) water barrier properties, (iii) air barrier properties, (iv) surface roughness, and (v) mechanical properties of the samples.

  • In this study, the size- and shape- dependent cytotoxicity of silver and gold nanoparticles have been examined. Silver nanoparticles inhibited the growth of the mold Aspergillus niger, and the one-dimension (Np1) and two-dimension (Np2) nanoparticles indicated more effective than the round ones (Np0). On the other hand, gold nanoparticles of the three types: nanostars (AuNS), polyethylene glycol coated nanostars (PEG-NS) and TAT peptide tagged nanostars (TAT-NS), placed impact on the BT549 human breast cancer cells with reduction in the cell viability.

  • In this paper, we report on the synthesis of solid polymer electrolytes (SPEs) on the basis of 95 wt.% PEO and 5 wt. of anhydrous cobalt (II) chloride hexahydrate (CoCl2 6H2O), hereafter called PCL5, by the spin-coating technique using different types of glass (normal, quartz, ITO) substrates. The PCL5 electrolyte exhibits the highest conductivity and the lowest optical bandgap and hence, it was selected as a component to fabricate the organic single-layer device.

  • The composition of nutrients in the fruits of amaranth with different color coat was studied. The protein composition of amaranth seeds was defined. The lipid complex of various types of amaranth has been determined. The oil from amaranth seeds by the method of raw material extraction was obtained. It has been established that amaranth oil approximates to cotton oil in terms of unsaturated fatty acids content.

  • This study was carried out to determine the suitability of sago starch blended with acrylamide as paper additive. Solutions of unmodified and blended sago starch with acrylamide, were prepared at 5% weight over volume (w/v) basis before the basic properties (i.e., pH, viscosity and solid content) were determined. The starches were then used to coat on laboratory made handsheets from recycled pulps. Various effects were studied, namely, modification of sago starch, addition of different types of initiator and further curing at different temperatures.

  • A laboratory test-rig for groundnut planter was developed for testing and calibrating the pneumatic seed metering mechanism. The experimental test rig mainly consists of main frame, seed hopper, seed metering system, power transmission system and sticky belt system. The metering unit is incorporated with a vertical seed plate held in a vacuum retaining chamber to singulate the seeds. A dial type vacuum gauge was provided in order to record the variation in suction pressure. A sticky belt was used to simulate the field surface during laboratory investigation.

  • ‘Seed balls’ are prepared by non-governmental organizations and enthusiastic school children to trees grow trees rapidly for ecosystem restoration. However, there is immense scope for technically improving the seed balls by ensuring the quality of seeds as well as media; further preparing cuboid structures, instead of ball like structure has immense scope in facilitating rooting of the newly emerging seedlings. Against this back drop, a series of experiments were conducted to standardize the seed coating technique, seed priming method and appropriate media for making seed cubes.
