A study (100 days duration) was conducted to evaluate the efficiency of an exotic earthworm species (epigeic-Eisenia foetida) for decomposition of different types of organic substrates (kitchen waste, agro-residues, institutional and industrial wastes including textile industry sludge and fibres) into valuable vermicompost. The percentage of, nitrogen,(More)
The concept of biostimulation i.e. enhancing the intrinsic degradation potential of a polluted matrix via the addition of amendments, nutrients, or other limiting factors has been used for a wide variety of xenobiotics. The objective of this research work was to study the degradation of atrazine (25 ppm) in soil amended with biogas slurry, mushroom spent(More)
Three cultivars (cvs.) of Gladiolus hybridus Hort., namely ‘Her Majesty’, ‘Aldebaran’ and ‘Bright Eye’ were successfully micropropagated. The cultures were established using intact cormels or segments of cormels and inflorescence axes on Murashige and Skoog (1962; MS) medium. The response depended on media supplements; both callus formation or direct(More)
The possible use of activated rice husk and activated alumina as the adsorbents of Cr(VI) from synthetic solutions and the effect of operating parameters were investigated. The activated rice husk carbon was prepared thermally in two sizes 0.3 and 1.0 mm. The maximum removal of Cr(VI) occurred at pH 2 by activated rice husk and at pH 4 by activated alumina.(More)
Sn0.9Cu0.1 nanoparticles were synthesized via a surfactant-assisted wet chemistry method, which were then investigated as an anode material for ambient temperature rechargeable sodium ion batteries. The Sn0.9Cu0.1 nanoparticle-based electrodes exhibited a stable capacity of greater than 420 mA h g(-1) at 0.2 C rate, retaining 97% of their maximum observed(More)
The present investigation deals with fluoride removal from aqueous solution by thermally activated neem (Azadirachta indica) leaves carbon (ANC) and thermally activated kikar (Acacia arabica) leaves carbon (AKC) adsorbents. In this study neem leaves carbon and kikar leaves carbon prepared by heating the leaves at 400 degrees C in electric furnace was found(More)
LiNi0.8 Al0.2 O2 with a higher Ni(3+) /Li(+) ordering, synthesized by the solution-combustion method, gives oxygen-evolution-reaction (OER) activity in alkaline solution that is comparable to that of IrO2 . This confirms that the octahedral-site Ni(IV) /Ni(III) couple in an oxide is an active redox center for the OER with -redox energy pinned at the top of(More)
