Effects of Auxin and Source of Explants on Callus Induction of Tropical Maize
(2012)
Induction of callus from explants is a critical process in regeneration, micropropagation and transformation of plants. Formation of callus from plant tissues on culture is affected by different factors. This study sought ...
User’s perception on ICT adoption in High schools
(2012)
Information Communication Technology (ICT) plays a crucial role in the effectiveness, efficiency and service delivery of any institution. ICT has also been credited with the potential to integrate world economies thus ...
Perpendicular magnetic anisotropy in Mn2VIn (001) films: An ab initio study
(2017-12-07)
First principles study of the magnetic anisotropy of Mn2VIn (001) films show perpendicular magnetic anisotropy (PMA), which increases as a function of the thickness of the film. Density functional theory (DFT) as implemented ...
First-Principle investigation of the structural, electronic and magnetic properties of Co2VIn and CoVIn Heusler compounds
(2017-01-05)
Investigation of the structural, electronic and magnetic properties of full-Heusler Co2VIn as well as half-Heusler CoVIn Cobalt based Heusler compounds using density functional theory (DFT) leads to the general conclusion ...
Reflectance, Transmittance and Absorptance of HDPE, LDPE, Glass and Sand Layer Used in a SAH
(2014)
The total Infra-red (IR) transmission of polymer films is a very important property in engineering, which determines their suitability for a specific application at a given temperature level. Aiming to investigate the ...
Perpendicular magnetic anisotropy in nearly fully compensated ferrimagnetic Heusler alloy Mn0.75Co1.25VIn: An ab initio study
(Elsevier, 2017-11)
First principles calculations are reported on perpendicular magnetic anisotropy (PMA) in nearly fully compensated ferrimagnetic Heusler compound Mn0.75Co1.25VIn. The structural, electronic and magnetic properties of ...
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 ...
Polylactic acid (PLA) viscoelastic properties and their degradation compared with those of polyethylene
(2015-12)
Polyethylene (PE) films are widely used in packaging. PE is a thermoplastic manufactured from nonrenewable petroleum resources. Due to its non–biodegradability, its films have posed serious pollution problems e.g. visual ...
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 ...
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 ...
