Diospyros discolor Willd., an endemic Philippine tree, is used in traditional medicine for managing various ailments like heart problems and hypertension. Because of its potential benefit to cause vascular smooth muscle relaxation, the present study aimed to investigate the methanol, hexane, ethyl acetate, n-butanol a…
A119 peptide (LSNIDYILIKAS), derived from the mouse laminin α1 chain sequence (residues 1321-1332), promotes cell attachment, neurite outgrowth, and amyloid-like fibril formation. In this study, we evaluated the structural requirements of A119 for biological activities and amyloid-like fibril formation. The attachment…
This chapter describes the preparation of ZnBeO and ZnBeMgO alloys and various applications of ZnO-based optoelectronic devices. In order to develop zinc oxide (ZnO)-based ultraviolet (UV) optoelectronic devices, it is necessary to find suitable materials with the same crystal structure as ZnO but with wider bandgap w…
Abstract In this paper we study the excitation spectrum of the organic conductor tetrathiafulvalene-tetracyanoquinodimethane (TTF-TCNQ) using finite temperature calculations. The effect of electronelectron interaction is considered within the random phase approximation (RPA). Our results show the temperature dependent…
Abstract The chemical bond approach to the glassy state is discussed. It is based on two concepts: Ovshinsky's idea of bond option as a necessary condition for amorphization, and Dembovsky's notions about hypervalent bonds (HVB) as alternative bonding state responsible for glass specificity and glass formation at all.…
The Role of Glycosylation in the Control of Processing and Cellular Transport of the Functional Amyloid PMEL17
Organic coatings based on synthetic resins provide excellent corrosion protection after making a good cleaning and surface preparation, followed by a suitable pretreatment depending on the type of substrate to be protected (Atta, 2006, Atta, 2007; Sathyanarayan, 2008 .) Such protection systems can be applied in a sing…
Heat treatment of bearing rings implies the risk of deformations caused by internal tension. In order to eliminate internal tension, hardening is followed by tempering. In general, tempering will remove the tension. However, this tempering is not sufficient for the socalled thin-walled rings AX series bearing rings to…
This chapter presents progress of the hybrid light emitting diodes (LEDs) based on Zinc oxide (ZnO) nanowires and other inorganic/organic semiconductors. It provides an overview of the ZnO-nanowirebased hybrid LEDs from the perspectives of the device configuration, growth methods of ZnO nanowires, and the selection of…
This chapter discusses the transport mechanism and surface-related transport properties of zinc oxide (ZnO) nanostructures, with particular interest in reports of the mobility exceeding state-of-the-art planar devices observed in ZnO nanowire (NW) devices. Most of ZnO nanostructures are grown with the three main metho…
This chapter explores the growth of zinc oxide (ZnO) scintillators for application in neutron detectors. It presents an overview of the theoretical basis for neutron detection and neutron-versus-gamma discrimination. The chapter addresses the ZnO crystal growth techniques with particular emphasis on bulk melt growth a…
This chapter examines the fundamental properties such as structural and optical properties of alloys and fabricated heterostructures including nanostructures. The exciton in oxide semiconductor seems to be easily localized by the alloy fluctuation, because a ZnO- based semiconductor has strong electronegativities and…
Ordinary laboratory voltmeters cannot be used for the measurement of electron motive force (emf) of glass electrode cells because of the high electrical resistance of glass electrodes (typically, 10-200 MΩ). Special high-impedance voltmeter circuits are required, which draw 10-12 A or less from the circuit. The pH met…
Abstract The shape of self‐assembling polymer–drug conjugates, influencing the cellular uptake, is one of the important factors to be considered for effective drug delivery. In this study, we described synthesis of polymeric drug conjugates of different morphologies with phytosphingosine (PHS) as a hydrophobic model d…
Poly (ethylene-co-tetrafluoroethylene-graft-styrene-sulfonate) was successfully prepared by irradiation grafting of a styrene monomer into ethylenetetrafluoro-ethylene (ETFE) films and followed by sulfonation of the graft chains. Five film sheets of ETFE which having a size of 3 cm x 8 cm, thickness of 25 µm were pack…
A nomenclature system is presented that can be applied to a range of spherical, tubular and planar structures. The starting point in this system is determined using semi-empirical calculations that establish the atomic charge of all species. This method accommodates all elements, different substitution patterns (i.e.,…
A special issue to commemorate the 1st M3
This chapter focuses on the features of epitaxial growth of zinc oxide (ZnO) on SiC as a route toward fabrication of hybrid light-emitting devices (LED). The imbalanced electron distribution and dangling atomic bonds are responsible for the columnar growth modes and related defects. It is also assumed, that the SiC su…
The field of quantum science and technology has generated many ideas for new revolutionary devices that exploit the quantum mechanical properties of small-scale systems. Isolated solid state spins play a large role in quantum technologies. They can be used as basic building blocks for a quantum computer or as ultra-se…
Abstract The pulse radar method is one of the fault location methods for power cables. It locates the breakdown point by measuring the delay time of the echo or the discharge signal coming from the breakdown point. The equipment for the pulse radar method is more compact compared to the Murray loop bridge, and its ope…
