In certain cells in the right upper quadrant of the abdominal ganglion of Aplysia depilans, a small excitatory post-synaptic potential (EPSP), produced by a weak stimulus to one pathway (test stimulus), underwent a prolonged facilitation when it was paired several times with a very strong stimulus to a second pathway (priming stimulus). In some cells this heterosynaptic facilitation was depende...

The decay rate of the Bacteriorhodopsin (BR) photocycle intermediate M412 and proton, the proton pump efficiency (H+/M412), the ratios of M412 to other intermediates and the rotational correlation time (tauc) in purple membrane (PM) fragments treated by the zwitterionic detergent 3-[(3-cholamidopropyl)-dimethylammonio]-1-propanesulfonate (CHAPS) with different concentrations were studied. The r...

The development of one-dimensional nanostructures has revolutionized electronic and photonic industries because their unique properties. present paper reports the low-temperature green synthesis boron carbide nanowires, diameter 14 nm length 2 µm, by condensation method using castor oil as carbon precursor. nanowires synthesized exhibit beaded chain morphology, bandgap energy 2.08 eV revealed t...

TiO2 nanopowder is prepared by simple sol-gel method using starting material as titanium isopropoxide with methanol and annealed at 600°C, 700°C and 800°C for 1 hour in air. X-ray diffraction pattern revealed the presence of both anatase and rutile phase in TiO2 specimens annealed at different temperatures. It is observed that the content of rutile phase and crystallite size increases with incr...

The optical energy gap of anthocyanin compounds from sea lettuce extract (Ulva lactuca L.) has been calculated using the Tauc plot method. Sea plants taken at Sanur Beach Bali. was dried then mashed and extracted for 24 hours, last being macerated through three cycles. extraction results are evaporated to obtain a thick solution. Extracted evaporated-extraction samples were characterized by UV-...

All thin ZnO films are synthesized by nebulizer on silicon substrates with growth periods of 10, 20, and 30 minutes. The characterizations performed ultraviolet-visible (UV-Vis) spectrophotometer, scanning probe microscopy, X-ray diffraction (XRD), the various durations minutes have been observed. results show that all samples polycrystalline hexagonal wurtzite varying root mean square (RMS) ro...

OBJECTIVE To i) compare incretin responses to oral glucose and mixed meal of diabetic patients with the normoglycaemic population and ii) to investigate whether incretin responses are associated with hypertriglyceridaemia and alanine aminotransferase (ALT) as liver fat marker. DESIGN A population-based study. METHODS A total of 163 persons with normal glucose metabolism (NGM), 20 with inter...

A hexagonal wurtzite ZnO photocatalyst was prepared via a precipitation method. CuS nanoparticles (NPs) and PbS quantum dots (QDs) were loaded onto hydrothermal method to obtain CuS/PbS/ZnO heterojunction photocatalyst. The obtained the abovementioned has significant absorption capabilities in ultraviolet near-infrared spectral regions, effectively reduced recombination of electron–hole pairs d...

Exploring the thickness-dependent electronic properties of ultrathin transition metal dichalcogenides is crucial for novel optoelectronic devices. Particularly important experimental information regarding bandgap width. This scarce and often inconsistent among several measurement techniques that were employed this task, such as optical absorption, scanning tunneling spectroscopy, photoconductiv...
