Glass photonics meets photovoltaics: general principles and a case study
(Springer Berlin Heidelberg, 2023-11-01)
In this study, we present a promising combination of glass photonics and photovoltaics to develop more efficient types of solar cells. Following up on earlier suggestions, we demonstrate that fundamental losses due to the ...
Structural and Mechanical Properties of NbN Alloyed with Hf, In, and Zr for Orthopedic Applications: A First-Principles Study
(MDPI, 2024-01-17)
The search for biocompatible, non-toxic, and wear-resistant materials for orthopedic implant applications is on the rise. Different materials have been investigated for this purpose, some of which have proved successful. ...
A Comparative Thermodynamic Study of AlF3, ScF3, Al0.5Sc0.5F3, and In0.5Sc0.5F3 for Optical Coatings: A Computational Study
(MDPI, 2023-11-27)
Optical coatings are thin layers of materials applied to optical components in order to modify the transmission, reflection, or polarization properties of light. The common materials used for optical coatings include ...
Investigating the Young's modulus of Cu-Al-Be shape memory alloy using a phase diagram, vibration spectroscopy and ultrasonic waves
(Elsevier, 2024-03-05)
This work presents a method for determining the effective Young’s modulus (Eeffective) and Poisson ratio of small specimens of a ternary shape memory alloy (SMA), Cu-Al-Be. The alloys were synthesized uniformly and ...
The plight of the house-helps (domestic workers) in selected estates in Eastland’s area, Nairobi County, Kenya
(International Journal of Social Sciences, 2019)
In Kenya, households in the middle class suburbs have increasing involvement of house-helps who in most cases take care of household chores. Moreover house helps have borne the brunt of being among the least paid in the ...
Accessing public transportation policies for persons living with disabilities in Kenya
(International Journal of Social Sciences, 2019)
Despite the fact that the constitution of 2010 has given priority to persons with disabilities with specific focus to bill of right, their right to movement is still curtailed in the public transportation sector system in ...
Characterization of atomic state evolution in the JC and anti-JC models: spin-displaced field modes in the quantum Rabi model
(Research gate, 2023-03-20)
In this article, characterization of the atomic state evolution in the Jaynes-Cummings (JC) and anti-Jaynes-Cummings (aJC) models means using the reduced atomic state degree of purity, concurrence and spin excitation number ...
Convergence of the Laplace and the alternative multipole expansion approximation series for the Coulomb potential
(Nature Publishing Group UK, 2023-09-25)
Multipole expansion is a powerful technique used in many-body physics to solve dynamical problems involving correlated interactions between constituent particles. The Laplace multipole expansion series of the Coulomb ...
