Carbon nanotubes (CNT) have found profound interest in advanced material composites due to its exceptional properties. With the modulus of elasticity in the range of 1.2 TPa and the strength of 60 GPa, it plays a vital role in strengthening the relatively softer plastics and acts as a good reinforcing element. However…
Ohmori et al. (1), then Mizuno et al. (2,3) showed in high voltage-high current electrolysis experiments the production of excess heat and abnormal production of hydrogen. Cirillo et al. (4) have shown transmutation of elements on the tungsten cathode during similar types of plasma electrolysis. Also, Fauvarque et al.…
A series of hydrogel thin films based on poly(vinyl alcohol) (PVA) and Chitosan (CTS) were synthesized via ultraviolet (UV) irradiation u sing acrylic acid (AAc) monomer as crosslinker, without adding photoinitiator. The pre pared hydrogels were used both as nanoreactors and immobilizing matrix for the formation of si…
Resumen.- En sus primeras aplicaciones comerciales, el proceso fue usado para soldar aluminio con un gas de protección inerte, dando lugar al término “MIG”(metal inert gas) el cual es todavía comúnmente usado cuando se refiere a este proceso. Se han añadido variaciones a este proceso, entre las cuáles se tiene el uso…
The great acceptance of calcium phosphate materials in the biomedical field comes from their close similirity to the mineral phase of bone. This make CaPs excellent subtrates for bone regeneration applications. In spite of possessing excellent bioactivity, osteoconductivity and biocompatibility in vivo, their behaviou…
Diese Arbeit behandelt Experimente zur Messung transienter Elektronendichte-Verteilungen mit der Femtosekunden-Röntgenbeugung. Es werden verschiedene Methoden der Röntgenbeugung beleuchtet und deren Charakteristika, speziell im Hinblick auf die Verwendung von ultrakurzen Röntgenimpulsen, erläutert. Die Rotationsmethod…
High temperature nanoindentation has been employed to study the influence of temperature on mechanical properties of ceramics in Ti1-xAlxN system. The temperature had a strong effect on the hardness of the bulk single crystal TiN (TiNbulk), leading to a drop from 21.4 ± 0.4 GPa at 22 °C to 13.7 ± 0.4 GPa at 350 °C. Pl…

In this paper, a potentiostat using active cascode current mirror is proposed to sense accurately the current generated by reduction reaction of K3Fe(CN)6. The proposed potentiostat is fabricated with “Dong-bu”0.11 ㎛ CMOS process and simulated by Cadence Spectre. Layout was performed by Cadence Virtuoso. The proposed…
For chemical decontamination of PWR primary systems the so called ASDOC-D process has been developed and qualified at the German PWR power station Biblis. In comparison to other chemical decontamination processes ASDOC-D offers a number of advantages: - ASDOC-D does not require separate process equipment but is comple…
In tailed bacteriophages and evolutionarily related herpes viruses, the portal protein is a central component of the DNA packaging molecular motor, which translocates viral genomic DNA into a preformed procapsid. The motor is the most powerful molecular machine discovered in nature, generating forces reaching ~50 pN a…
Ribonuclease enzymes (RNase) have been used effectively in the treatment of certain cancers and other properties that may be applicable in biotechnology. In order to identify the RNase activity in the latex of Calotropis procera and Pedilanthus tithymaloides, tropical plants samples were collected from adult plants lo…

Based on an effective screen-printing process, a novel sandwich layered cathode electrode was developed on a cathode faceplate. The ZnO electrode was sandwiched between an indium tin oxide (ITO) electrode layer and a silver electrode layer, and the carbon nanotube was prepared directly on the exposed ITO electrode lay…

In this study, the beet pulp pressing water using nanofiltration process investigated. The effect of temperature (25, 40 and 55 °C), the transmembrane pressure (10, 15 and 20 bar) and the brix (1, 2, and 30) on the rejection of sodium, potassium, calcium, magnesium, chloride and sulfate was studied. Then, physical mod…
Deposition of size-selected metal nanoclusters on a substrate with very low kinetic energy helps to keep the clusters intact with respect to their shape and size as compared to clusters in ight condition. Here we report formation of isolated monodispersed islands of copper of desired size on carbon film by deposition…
