In this study, the influence of direct current (DC) biasing on the growth of titanium dioxide (TiO₂) layers and their nucleation behavior has been investigated. Titania films were prepared by plasma enhanced atomic layer deposition (PEALD) using Ti(OiPr)₄ as metal organic precursor. Oxygen plasma, provided by remote inductively coupled plasma, was used as an oxygen source. The TiO₂ films were d...

This paper presents low-power versions of two circuits often used in analog VLSI models of neural systems. The circuits model the spiking behavior of the axon hillock and the pulse propagation of axons.

We simulate the formation of experimentally observed trapezoidal hillocks on etched Si(110) surfaces, describing their generic geometrical shape and analyzing the relative stability and/or reactivity of the key surface sites. In our model, the hillocks are stabilized by Cu impurities in the etchant adsorbing on the surface and acting as pinning agents. A model of random adsorptions will not res...

Silver (Ag) is one of the seven metals of antiquity and an important engineering material in the electronic, medical, and chemical industries because of its unique noble and catalytic properties. Ag thin films are extensively used in modern electronics primarily because of their oxidation-resistance. Here we report a novel phenomenon of Ag nano-volcanic eruption that is caused by interactions b...

Forest patches in urban areas can have the potential to provide shelter, resources, and breeding space for small mammals. This study aimed explore diversity, abundance, habitat associations of non-volant mammals forest Kathmandu Valley. Three sites were selected study: Ranibari Community Forest, Swayambhunath Hillock, Coronation Garden Tribhuvan University. The roost survey, line transect surve...
