A new class of thiazole based organogelator was synthesized and characterized by various techniques such as VT-NMR, IR, single crystal and powder X-ray diffraction. The role of unusual H-bond interactions such as C–H⋯N and van der Waals interactions were probed as driving forces for physical gelation of various polar…
A test loop, HANS (Heavy metal Alloy Natural circulation Study loop) is installed in BARC (Bhabha Atomic Research Centre) for thermal hydraulic, instrumentation development and material compatibility related studies in Lead Bismuth Eutectic (LBE) coolant. Steady state natural circulation characteristics in the LBE loo…
A polymer incorporated with a pyrenylcarbazole pendant poly(12-(3-(pyren-1-yl)-carbazol-9-yl)dodecyl methacrylate, denoted as PCP) was synthesized and applied in the functionalization of multi-walled carbon nanotubes (MWCNTs) by noncovalent π–π interaction. The PCP–MWCNT hybrids were isolated and characterized by SEM,…
An ultrathin vanadium pentoxide nanosheets colloid has been synthesized using peroxovanadium coordination compound (PVC) as a precursor through a simple, light-assisted aqueous-phase synthetic strategy. The μ-chelated triangle structured radicals, obtained by selective decomposition of the PVC precursor under UV irrad…
Shell thickness of Rapana venosa was investigated from ecologically different places of the Azov – Black Sea basin. In the formation of the shell thickness there are two major trends: thickening with age, and inversely proportional to the size of the thickening of even-aged individuals of the same population. Shell th…

A facile and high yielding synthesis of porphyrin appended thiazoles 5 from the reaction of 5‐(4‐thiocarboxamidophenyl)‐10,15,20‐triphenylporphyrin with α‐bromo ketones has been described. The fluorescence studies of synthesized porphyrin appended thiazoles 5 in chloroform indicate that porphyrin π system is not great…
In this study, an algorithm for identification of elastic and viscoelastic constants of a recently developed constitutive equation for thermoplastics and resins is presented. The equation has been applied to model the viscoelastic response of ultra high molecular weigth polyethylene. In order to determine the material…
A biodegradable composite (PLA/KBF blends) was prepared using melt blending technique in a brabender mixer and characterized with FTIR and TGA analyzer. Five percent of triacetin and glycerol contents were used as plasticizers to plasticise PLA matrix. KBF was treated with 4% NaOH solution, while 30 wt% of fibre loadi…
Modified atmosphere (MA) packages were prepared for Royal Delicious apple with an aim to achieve the optimum storage atmosphere within the packages in minimum possible time. Apples were harvested at their commercial maturity and respirtion rate of the fruits was measured at temperatures between 0 -25C. On the basis of…
Magnetic drug delivery systems have been emerged as a prominent technique for site-specific targeting of various pharmacological agents throughout the last few decades.With the support of a magnetic field, it avoids reticuloendothelial system and directs the drugs to reach the target precisely.Magnetic carriers like n…
A new six mixed Ligand complexes of some transition metal ions Mn (II) , Fe (II) , Co(II) , Ni(II), Cu(II)and non transition metal ion Cd(II)) with L-valine (Val H ) as a primary Ligand and 1,10-phenanthroline(phen) as a secondary Ligands have been prepared. All the prepared complexes have been characterized bymolar c…
Abstract: In the present paper, a series of bimodal PBX compositions containing coarse (90 µm) and fine (<1 µm) HNS (2,2’4,4’6,6’-hexanitrostilbene) and hybrid PBX compositions based on HNS and HMX (1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane) in varying mass ratios, along with the fluoropolymer Viton-A, a vinylide…
Electrochemical corrosion is known to degrade solar cells during artificial and outdoor weathering. The combination of humidity and acetic acid in combination with leakage currents lead to corrosion of the contact fingers of the solar cells. The polyolefin backsheet shows an extraordinary behavior. The transmission ra…
Abstract—The aim of this study was to investigate the feasibility of two decontaminating processes, ozonation and electrocoagulation, to decolorize wastewater generated by humid finishing leather production. With the objective to determine if one or both process could remove color, benchscale experiments were conducte…
We report the design and demonstration of nanowire temperature reporters. Metal alloys with tunable melting points were used to create nanowires in nanopores of anodic aluminum oxide using mechanical pressure injection. When exposed to temperature above their melting points, nanowires began to break up into disconnect…
The discoveries of Leonard of Pisa, better known as Fibonacci, are revolutionary contributions to the mathematical world. His best-known work is the Fibonacci sequence, in which each new number is the sum of the two numbers preceding it. When various operations and manipulations are performed on the numbers of this se…
In this study, we report the characterisation of biosynthesised silver nanoparticles and investigate the antibacterial effects of biologically synthesised silver nanoparticles (AgNPs) on Mycobacterium tuberculosis.
Single layer sheets of graphene show special electrical properties that can enable the next generation of smart ICs. Recent works have proven the availability of an electrostatically controlled pn-junction upon which it is possible to design multi-function reconfigurable logic devices that naturally behave as multiple…
