Two-dimensional graphene–HfS2 van der Waals heterostructure as electrode material for alkali-ion batteries
(The Royal Society of Chemistry, 2020-07)
Poor electrical conductivity and large volume expansion during repeated charge and discharge is what has
characterized many battery electrode materials in current use. This has led to 2D materials, specifically
multi-layered ...
Frequency stability characterization: DFB laser and Raman pump performance on a distributed clock signal over 24.69 km fiber
(Journal of the Optical Society of America, 2020-07)
Distribution of timing and frequency signals in a fast-changing world requires unprecedented levels of stability for
characterization.Transfer of frequency references over long distance without introducing any additional ...
On Unitary Invariance of Some Classes of Operators in Hilbert Spaces
(Pure Mathematical Sciences, 2020)
It is a known fact in operator theory that two similar operators have equal spectra but they
do not necessarily have to belong to the same class of operators. However, under the
stronger relation of unitary equivalence ...
Prevalence and Risk Factors of Elevated Blood Pressure and Elevated Blood Glucose among Residents of Kajiado County, Kenya: A Population-Based Cross-Sectional Survey
(International Journal of Environmental Research and Public Health, 2020)
Kenya is experiencing a rising burden of non-communicable diseases (NCDs), yet data
to inform effective interventions are limited. We investigated the prevalence of elevated blood
pressure, elevated blood glucose and ...
