We report atomic layer deposition (ALD) of ZnO thin films on O-polar surface crystalline substrates at the relatively low temperatures 120, 150, and 200 °C. The as-grown are studied with aberration-corrected transmission electron microscopy diffraction contrast, photoluminescence (PL), photovoltage (SPV) spectroscopy. find that homoepitaxial have a monocrystalline structure density basal stacki...

The use of ground-mounted photovoltaic (GMPV) systems for power generation is becoming popular these days. GMPV demand vast land areas their installations, and this has resulted in land-use conflicts. As a result, mitigating the issues, few novel ways (PV) installations have emerged that include floating (FPV) submerged photovoltaics (SPV). However, literature, many raised concerns over FPV SPV...

Hetero-bilayers, composed of transition metal dichalcogenide (TMD) monolayers MoS2 (1L-MoS2) and 1L-WS2, are grown on Al2O3 substrates through sulfurization pre-deposited thin films. A very smooth surface morphology the uniform contact potential difference (CPD) maps show that high-quality homogeneous TMD layers obtained. The light-induced CPD change, is, photovoltage (SPV), samples is investig...

To investigate the contribution of the vestibular velocity-storage mechanism (VSM) to the vertical rotational vestibulo-ocular reflex (rVOR) we recorded eye movements evoked by off-vertical axis rotation (OVAR) using whole-body constant-velocity pitch rotations about an earth-horizontal, interaural axis in four healthy human subjects. Subjects were tumbled forward, and backward, at 60 deg/s for...

PURPOSE To investigate the effect of age on optokinetic nystagmus (OKN) in response to stimuli designed to preferentially stimulate the M-pathway. METHOD OKN was recorded in 10 younger (32.3 +/- 5.98 years) and 10 older (65.6 +/- 6.53) subjects with normal vision. Vertical gratings of 0.43 or 1.08 cpd drifting at 5 degrees /s or 20 degrees /s and presented at either 8% or 80% contrast were di...

Previous research has found developmental decreases in temporal variability in speech. Relatively less work has examined spectral variability, and, in particular, variability in consonant spectra. This article examined variability in productions of the consonant /s/ by adults and by 3 groups of children, with mean ages of 3;11 (years;months), 5;04, and 8;04. Specifically, it measured the influe...

Dye-sensitized solar cells (DSCs) provide a promising third-generation photovoltaic concept based on the spectral sensitization of a wide-bandgap metal oxide. Although the nanocrystalline TiO2 photoelectrode of a DSC consists of sintered nanoparticles, there are few studies on the nanoscale properties. We focus on the microscopic work function and surface photovoltage (SPV) determination of TiO...

The stability performance of smart grid power systems is critical and requires special attention. Additionally, the combination Battery Energy Storage (BES) systems, Solar Photovoltaic (SPV), wind in intelligent model provides utilities with excellent efficiency dependability. However, a coordination PV other resources frequently results severe issues, such as outages or disruptions. A outage m...

South Africa is one of the most carbon-intensive economies in world, but it presently experiencing an energy crisis, as its utility company cannot meet country’s demands. The use renewable sources and retiring coal-fired power stations are two important ways alleviating this problem, well decarbonizing grid. Repurposing for generation (RCP-RES) while maintaining sustainability reliability has r...
