Shell-ferromagnetism and decomposition in off-stoichiometric Ni50Mn50–xSbx Heuslers
(AIP Publishing, 2019-01-28)Off stoichiometric Heuslers in the form Ni50Mn50−xZx, where Z can be a group 13–15 element of the periodic system, decompose at about 650 K into a ferromagnetic full Heusler Ni50Mn25Z25 and an antiferromagnetic Ni50Mn50 ... -
Spectrophotometric Determination Of Copper (Ii) In Soil From Ahero Rice Irrigation Schemes Using Hydroxytriazene
(IOSR Journal of Applied Chemistry, 2020)A simple, rapid, sensitive and cost effective spectrophotometric technique for the determination of copper (II) using 3-hydroxy-3-m-tolyl-1-O-carboxyphenyltriazene has been reported. The complex formed was greenishyellow ... -
“The startling effect of the sound of C. Afra And A. Tormotus on the female A. gambiae”
(2012)The female Anopheles gambiae, a malaria vector, detects ultrasound by its antenna, initiating an attractive or repulsive response. Modern electronic mosquito repellents exploit this concept in attempt to control malaria, ... -
Structural, Electronic and Magnetic Properties of the Heusler Alloy Mn₂VIn: A Combined DFT and Experimental Study
(2017-12)Structural, electronic and magnetic properties of the Heusler alloy Mn₂VIn have been investigated using the density functional theory and experimental techniques. Unlike many other Heusler compounds, Mn₂VIn is not predicted ... -
Study of Humidity and UV wavelength effects on degradation of photo irradiated polyethylene films using DMA
(2012-03-12)Plastic bags, mostly made of polyethylene, cause pollution as solid waste due to their nondegradable nature. Accelerated degradation, as a solution to mitigate the menace, can be achieved through moisture enhanced photolysis. ... -
Study of Humidity and UV Wavelength Effects on Degradation of Photo-Irradiated Polyethylene Films Using DMA
(2011-06-09)Plastic bags, mostly made of polyethylene, cause pollution as solid waste due to their nondegradable nature. Accelerated degradation, as a solution to mitigate the menace, can be achieved through moisture enhanced photolysis. ... -
Study of Temperature and UV wavelength Range Effects on degradation of Photo Irradiated polyethylene films using DMA
(2011-06-09)Plastic bags mostly made of polyethylene (PE) cause pollution as solid waste due to their non-degradability nature. Initiation of a degradative process by enhanced photo-oxidation is a possible method for an accelerated ... -
Synthesis and electrochemical studies of heterobinuclear complexes containing copper and molybdenum nitrosyl groups linked by Schiff base ligands
(Springer, 2000-08)Abstract The reaction of [MoCl(NO)Tp * = tris(3,5-dimethylpyrazolylborate] with copper Schiff base complexes derived by condensation of one mole each of 2,5-dihydroxybenzaldehyde and salicylaldehyde with α,ω diamines ... -

Thermal Conductivities of Selected Solid Waste Materials Determined Using Lees’ Disc Method
(International Journal of Research Publications (IJRP.ORG), 2020-04-02)In this study, the coefficients of thermal conductivities have been determined. The goal was to find out the best insulator among the recyclable and locally available materials which can be adopted for use to replace the ... -
Trimetallic complexes containing Nickel or Palladium and two Molybdenum nitrosyl groups
(1997)The reaction of [Mo(NO){HB(dmpz)3}Cl2] [HB(dmpz)3 = tris(3,5-dimethylpyrazolyborate] with nickel(II) and palladium(II) Schiff-base complexes derived by condensation of two mole equivalents of 2,5-dihydroxybenzaldehyde with ... -
UV Absorption and dynamic mechanical analysis of polyethylene films
(2014-12)Photooxidative processes that lead to chain scission and chain linking in polymers play an important role in polymer degradation. These processes are induced by both ultraviolet (UV) and visible light absorption. The ... -
Volatility Modelling of the Nairobi Securities Exchang
(2012-03)In this paper we identify the most efficient ARCH-type model that can be applied to the Nairobi stock exchange data for forecasting and prediction of volatility which in turn is important in pricing financial derivative ...
