In this paper, three types of optical textured glass substrates were prepared at the glass/transparent conductive oxide interface using polydimethylsiloxane nanoimprint lithography to increase conversion efficiency dye-sensitized solar cells (DSSCs). There textures: nanotexture, microtexture, and micro/nano double texture. terms characteristics, it was confirmed that reflectance all lower than ...

Multiphoton lithography allows the high resolution, free-form 3D printing of structures such as micro-optical elements and scaffolds for Tissue Engineering. A major obstacle in its application these fields is material structure autofluorescence. Existing photoresists promise near zero fluorescence at expense poor mechanical properties, low efficiency. Sudan Black B a molecular quencher used dye...

’Moon-Glade’ Background Oriented Schlieren method for measuring liquid surface deformations was used. The is based on the analysis of background dots pattern images reflected from surface. a transparent polyester film with dots, which located at certain distance above liquid. Compared to other methods that use image, this technique has following advantages: (1) it allows restoring instantaneous...

The paper discusses the effect of stirrer and container rotation direction on mixing index (Ip). chaos theory is result an in-depth study various problems that cannot be answered by two previous major theories, namely quantum mechanics relativity. Effective flow area does not depend rapid stirring. This uses a with double stirrer, camera, programmable logic controller, tachometer, 6 A adapter, ...

indium tin oxide (ito) thin films were deposited on glass substrates by rf sputtering using an ito ceramic target (in2o3-sno2, 90-10 wt. %). after deposition, samples were annealed at different temperatures in vacuum furnace. the post vacuum annealing effects on the structural, optical and electrical properties of ito films were investigated. polycrystalline ito films have been analyzed in wide...

The counter electrode (CE) containing catalyst layer and transparent conducting oxide (TCO) is by far the most expensive components in Dye sensitized solar cells (DSSC) due to use of rare earth element such as Pt. potential replacement both TCO Pt-based would essentially pave way mass commercialization technology DSSC. In this investigation, an attempt has been made replace Pt with a single del...

Three-dimensional (3D) hierarchical nanoscale architectures comprised of building blocks, with specifically engineered morphologies, are expected to play important roles in the fabrication of 'next generation' microelectronic and optoelectronic devices due to their high surface-to-volume ratio as well as opto-electronic properties. Herein, a series of well-defined 3D hierarchical rutile TiO2 ar...

This study evaluated in vitro the effect of using the operating microscope on repairing furcation perforations using Vitrebond or mineral trioxide aggregate. Forty-six human molar teeth were mounted into a jig attached to a simulated jaw. The teeth were allocated randomly to four groups (n = 10). Furcal perforations were made in the teeth using an ISO 012 round bur in a slow-speed hand-piece. E...

This proposed research focuses on the preliminary investigation for developing a novel detection method for retained surgical items (RSIs), specifically surgical sponges. Several methods are currently available for the avoidance and detection of RSIs; however, they remain a significant problem. The proposed research utilizes the transparent near-infrared region (800 nm) which is devoid of fluor...
