Microstructural and Elastic Properties of Stable Aluminium-rich TiAl and TiAl2 Formed Phase Intermetallics
(North-Holland, 2021)
We studied aluminium-rich Ti-Al (Ti32Al68 and Ti40Al60) binary alloys that were composed of TiAl and TiAl2 lamellar microstructures. The law of mixtures was employed in calculating the theoretical Young’s moduli. The lattice ...
Investigation of long acoustic waveguides for the very low frequency characterization of monolayer and stratified air-saturated poroelastic materials
(Elsevier, 2021)
When sound propagates in a porous medium, it is attenuated via several energy loss mechanisms which are switched on or off as the excitation frequency varies. The classical way of measuring acoustic energy loss in porous ...
Enhancing climate action at grassroots levels in least developed countries: unlocking bio-briquetting opportunities for communities in Wajir, Vihiga, Kitui, and Kajiado counties in Kenya
(Inderscience Publishers (IEL), 2021)
Grassroots communities are often the hardest hit by climate change. They also appreciably contribute to the problem through activities like deforestation, land use changes, and cooking with firewood. Bio-briquettes from ...
Ab initio study of elastic properties of orthorhombic cadmium stannate as a substrate for the manufacture of MEMS devices
(Science Direct, 2021)
The elastic properties of the orthorhombic cadmium stannate (Cd2SnO4) were investigated using density functional theory, applying both energy-strain relationship (which is found in the literature) and stress-strain ...
Symmetry conjugates and dynamical properties of the quantum Rabi model
(Cornell University, 2021)
Symmetry transformations have proved useful in determining the algebraic structure and internal
dynamical properties of physical systems. In the quantum Rabi model, invariance under parity symmetry transformation has been ...
Comparative Investigation of Fullerene PC 71 BM and Non-fullerene ITIC-Th Acceptors Blended With P3HT or PBDB-T Donor Polymers for PV Applications
(Frontiers, 2021)
Fundamentally, organic solar cells (OSCs) with a bulk-heterojunction active layer are
made of at least two electronically dissimilar molecules, in which photoabsorption in one
(donor) generates Frenkel excitons. The ...
The anti-Jaynes-Cummings model is solvable : quantum Rabi model in rotating and counter-rotating frames ; following the experiments
(Cornell University, 2021)
This article is a response to the continued assumption, cited even in reports and reviews of recent experimental breakthroughs and advances in theoretical methods, that the antiJaynes-Cummings (AJC) interaction is an ...

Kenya’s response to the COVID-19 pandemic: a balance between minimising morbidity and adverse economic impact
(African Academy of Sciences, 2021)
Coronavirus disease 2019 (COVID-19) has ravaged the world’s socioeconomic systems forcing many governments across the globe to implement unprecedented stringent mitigation measures to restrain its rapid spread and adverse ...
Rabi oscillations, entanglement and teleportation in the anti-Jaynes-Cummings model
(Cornell University, 2021)
This paper provides a scheme for generating maximally entangled qubit states in the anti-JaynesCummings interaction mechanism, so called entangled anti-polariton qubit states. We demonstrate
that in an initial vacuum-field, ...
