Polyvinyl alcohol/Chitosan blend (PVA/CC(50:50) and (PVA/CC/10wt% SiO2) composite, were prepared by casting method on a glass plate. Poly (vinyl alcohol)-chitosan blend films were prepared with a thickness about 250 micron. The crystalline structure of PVA and fingerprint of semi-crystalline of chitosan was confirmed…
A maximum laser power of 2.4 W was obtained at a wavelength of ~ 2040 nm for 23 W of absorbed pump power with a slope efficiency of 21.6 % with respect to absorbed power.
Introduction: Irrigation is an important procedure during root canal treatment once it can help cleaning those areas of the root canal system not directly reached by instruments Objective: The aim of this study was to evaluate the biocompatibility and disinfection ability of silver nanoparticles dispersion in comparis…
The recent statement on tissue reactions issued by the International Commission on Radiological Protection in April 2011 recommends a very significant reduction in the equivalent dose annual limit for the eye lens from 150 to 20 mSv y(-1); this has stimulated a lot of interest in eye lens dosimetry in the radiation pr…
Controlling the formation of large and homogeneous arrays of bionanostructures through the self-assembly approach is still a great challenge. Here, we report the spontaneous formation of highly ordered arrays based on aligned peptide nanostructures in a solution as well as at an interface by self-assembly. By controll…
Today Hadron Accelerators with high intensity and high brightness beams increasingly rely on transverse feedback systems for the control of instabilities and the preservation of the transverse emittance. With particular emphasis, but not limited to, the CERN Hadron Accelerator Chain, the progress made in recent years,…
Drying of a coated paper is modeled and simulated. The paper sheet is assumed to form three zones, and each zone has its own drying mechanism. Coupling of energy and mass balances must be used in order to solve differential equations. The simulations are carried out in various drying conditions i.e., only hot air dryi…
Metal phthalocyanine complexes with different charges, hydrophobicity and metal ions were synthesized and studied for antimicrobial photodynamic therapy of pathogenic bacterial and fungal model strains. Ten positively charged complexes with the metals Zn ( II ), Al ( III ), Ga ( III ), In ( III ), Si ( IV ) and Ge ( I…
We have reported synthesis and vesicular assembly of a novel amphiphilic polyurethane with hydrophobic backbone and hydrophilic pendant carboxylic acid groups which were periodically grafted to the backbone via a tertiary amine group. In aqueous medium the polymer chain adopted a folded conformation which was stabiliz…
Ultrasound-mediated drug delivery under the guidance of an imaging modality can improve drug disposition and achieve site-specific drug delivery. The term focal drug delivery has been introduced to describe the focal targeting of drugs in tissues with the help of imaging and focused ultrasound. Focal drug delivery aim…
The selectivity of DNA recognition inspires an elegant protocol for designing versatile nanoparticle (NP) assemblies. We use molecular dynamics simulations to analyze dynamic aspects of the assembly process and identify ingredients that are key to a successful assembly of NP superlattices through DNA hybridization. A…
A novel pyrrole-fused azacoronene family was synthesized via oxidative cyclodehydrogenation of the corresponding hexaarylbenzenes as the key step, and the crystal structures of tetraazacoronene 3b and triazacoronene 4a were elucidated. The photophysical properties for neutral compounds 1-4 were investigated using stea…
Abstract The phase transformation behavior and heat treatment response of Cu–2.8Ni–0.6Si (wt%) alloy subjected to different heat treatments were studied by X‐ray diffraction, transmission electron microscopy observation, and measurement of hardness and electrical conductivity. The variation of hardness and electrical…
Prolonged exposure to excessive reactive oxygen species (ROS) increases risk factors for many diseases. Therefore, elimination of ROS as well as prevention of its production becomes critically important. In the present study, we evaluated the levels of cytotoxicity and ROS scavenging activity induced by synthetic plat…
Abstract Fe 73.5 Cu 1 Nb 3 Si 13.5 B 9 (or FeCuNbSiB) powder/S‐glass fiber‐reinforced epoxy composite panels were prepared by mold pressing method. Metallographic analysis shows that the amorphous powders are evenly distributed between the layers of S‐glass fibers. The effects of the FeCuNbSiB powder mass fraction on…
Block copolymer (BCP) self-assembly is an effective and versatile approach for the production of complex nanopatterned interfaces. Monolayers of BCP films can be harnessed to produce a variety of different patterns, including lines, with specific spacings and order. In this work, bilayers of cylinder-forming polystyre…
Polypeptoid brushes were synthesized by surface-initiated polymerization of N-substituted glycine N-carboxyanhydrides on self-assembled amine monolayers. Using the presented grafting-from approach, polypeptoid brush thicknesses of approximately 40 nm could be obtained as compared to previously reported brush thickness…
We have measured the inverse spin Hall effect (ISHE) in \textit{n}-Ge at room temperature. The spin current in germanium was generated by spin pumping from a CoFeB/MgO magnetic tunnel junction in order to prevent the impedance mismatch issue. A clear electromotive force was measured in Ge at the ferromagnetic resonanc…
The splitting of water with sunlight using photoelectrochemical cell (PEC) to produce hydrogen is a promising avenue for sustainable energy production. The greatest virtue of PEC is that it uses sunlight as the only source to split water, but its efficiencies are still quite low due to poor performances of the availab…
First of all, the author describes a great variety of liquid crystalline phases (=mesophases) and their classifications from a classical viewpoint of the molecular shapes. The classical classification is unable to rationally overview the whole liquid crystalline phases. Therefore, the author adopts universal linear al…
