Nanocrystalline titanium (iv) oxide paste has been deposited on Fluorine doped tin oxide glass substrate by the blade method. The deposited film was subjected to thermal treatment to obtain an electrode foe a photo-electrochemical cell. The electrode was sensitized with prophyrin dye which was a local dye extracted from carica papaya leaves. Avaspec 2.1 spectrophotometer was used to obtain the ...

Spin-polarized gapless surface states in topological insulators form chiral Dirac cones. When such materials are reduced to thin films, the Dirac states on the two faces of the film can overlap and couple by quantum tunneling, resulting in a thickness-dependent insulating gap at the Dirac point. Calculations for a freestanding Sb film with a thickness of four atomic bilayers yield a gap of 36 m...

A novel capacitive tactile sensor using a polyurethane thin film is proposed in this paper. In previous studies, capacitive tactile sensors generally had an air gap between two electrodes in order to enhance the sensitivity. In this study, there is only polyurethane thin film and no air gap between the electrodes. The sensitivity of this sensor is higher than the previous capacitive tactile sen...

The carbon nanotube (CNT) film is used to fabricate the novel carbon nanotube film cathode (CNTFC) gas sensor, and the working voltage of the novel sensor at atmospheric pressure decreases to several hundred volts from the value of more than thousand volts of the traditional discharge gas sensor, however it is limited by that the space charge in the gap is very hard to diffuse after the breakdo...

Objective: To compare the morbidity following episiotomy repair by rapidly absorbed polyglactin and chromic catgut. Materials & Methods: This prospective longitudinal study was conducted in the Department of Obstetrics and Gynaecology, Medical College, Kolkata. 100 primigravida with episiotomy were divided into 2 groups Group I:CC (n=50) repaired with no 1,0 chromic catgut and Group II:VR (n=50...

A 2.5 monolayer (ML) thick graphene film grown by chemical vapor deposition of thermally dissociated C(2)H(4) on MgO(111), displays a significant band gap. The apparent six-fold low energy electron diffraction (LEED) pattern actually consists of two three-fold patterns with different 'A' and 'B' site diffraction intensities. Similar effects are observed for the LEED patterns of a 1 ML carbon fi...

Rapid formation of a porous alumina film without oxide burning was achieved by anodizing in etidronic acid at large current densities using nanodimpled aluminum surface. After the electropolished specimens were galvanostatically anodized 0.3 M solution 293 K, uniform formed relatively low up to 20 Am−2. first process, an array dimples fabricated on surface removal chromic acid/phosphoric soluti...
