BACKGROUND: Rapid diagnosis for time-sensitive illnesses such as stroke, cardiac arrest, and septic shock is essential for successful treatment. Much attention has therefore focused on new strategies for rapid and objective diagnosis, such as Point-of-Care Tests (PoCT) for blood biomarkers. Here we use a biomimicry-ba…
Dissolution of LnI3 (Ln = La, Ce) in acetonitrile (MeCN) results in the highly soluble solvates LnI3(MeCN)5 [Ln = La (1), Ce (2)] in good yield. The ionic complex [La(MeCN)9][LaI6] (4), containing a rare homoleptic La(3+) cation and anion, was also isolated as a minor product. Extending this chemistry to NdI3 results…
A nonlinear lumped element model for planar magnetics is presented. This technique develops an equivalent circuit model for multilayer planar magnetic components using 1-D analysis of Maxwell's equations. Conducting layers are represented as impedance networks, while the insulating regions are modeled as air-cored ind…
Surface functionalization of quantum dots (QDs) is one of the most important aspects of designing and preparing the desired QDs for intended optical and biomedical applications. In this paper, we synthesized aqueous-phase Cu2S quantum dots coating by three different stabilizers, i.e. mercaptoacetic acid, mercaptopropi…
Single-crystal silicon carbide (SiC) thin-films on silicon (Si) were used for the fabrication and characterization of electrically conductive distributed Bragg reflectors (DBRs) on 100 mm Si wafers. The DBRs, each composed of 3 alternating layers of SiC and Al(Ga)N grown on Si substrates, show high wafer uniformity wi…
Adsorption of a homopolymer chain onto a heterogeneous stripe-patterned surface is studied in the framework of the three-dimensional partially directed walk model of the polymer by using the generating function approach. Both annealed random and quenched regular (periodic) stripe-patterned surfaces are considered. For…
A process for obtaining trichlorosilane (TCS or SiHCl3) from hydrogenation of silicon tetrachloride (STC or SiCl4) through control of the temperature along a one-dimensional plug-flow reactor at atmospheric pressure was simulated using a reaction model that was built based on a literature review: Rate coefficients for…
We report the synthesis of plasmonic Cu2-x Se@ZnS core@shell nanoparticles (NPs). We used a shell growth approach, starting from Cu2-x Se NPs that have been shown before to exhibit a localized surface plasmon resonance (LSPR). By careful synthesis planning we avoided cation exchange reactions and received core@shell n…
The synthesis and characterization of a novel gadolinium(III) DOTA complex functionalized with a boron-dipyrromethene derivative (BODIPY) is described. The assembly of the complex relies on azide diazotransfer chemistry in a copper tube flow reactor. The azide thus formed is coupled directly with an alkyne via click c…
ABSTRACT This paper is aimed at studying the effect of the grade and the granulometry of poly(lactic acid) (PLA) on its processability by rotational molding. Two PLA grades were considered: a low melt flow rate (MFR), high viscosity, material, characterized by an excellent quenchability, leading to a completely amorph…
This study focuses on understanding the damage behavior caused by the lightning strike of carbon nanotube (CNT) doped carbon fiber reinforced plastic (CFRP) composites. Quasi isotropic CFRP laminated composite plates used in aerospace structures are modeled to investigate behavior of lightning strike damage. Abaqus fi…
Not long after the first personal computers started entering people's homes, Intel fell victim to a nasty kind of memory error. The company, which had commercialized the very first dynamic random-access memory (DRAM) chip in 1971 with a 1,024-bit device, was continuing to increase data densities. A few years later, In…

In the present study, paclitaxel (PTX) were encapsulated with polyethylene glycol (PEG)-polylactide (PLA)/D-α tocopheryl polyethylene glycol 1000 succinate (TPGS) (PEG-PLA/TPGS) and the enhanced anti-tumor activity of this PTX mixed micelles (PTX-MM) was evaluated in lung cancer cells. The PTX-MM prepared by a solvent…
ABSTRACT Rigid polyurethane‐polyisocyanurate (PUR‐PIR) foams modified with tris(5‐hydroxypentyl)‐2‐hydroxypropane‐1,2,3‐tricarboxylate (THHT) were synthesized. Selected foams were subjected to degradation in an aging oven for 168, 346, and 504 h, respectively. These foams have been exposed to UV radiation. FTIR analys…
Abstract NiL 2+ (L = 1,4,8,11‐tetraazacyclotetradecane) was entrapped in sol–gel matrices in the presence of graphite. The matrices thus prepared serve as electrocatalysts for the oxidation of amines. The results point out that: (1) It is easy to prepare electrocatalytic electrodes by using this approach. (2) The prop…
Abstract A major challenge to turn the potential of carbon nanotubes (CNTs) into customer applications is to reduce or eliminate their toxicity. Taking into account health and safety concerns, intensified research efforts have been conducted to improve the biocompatibility of CNTs, including the development of new sho…
An intuitively persistent enhancement of the local surface potential of BiFeO3 layers in both heterostructures of BiFeO3/SrRuO3/SrTiO3 and BiFeO3/Sr0.09Nb0.01TiO3 was observed by the Kelvin probe force microscopy technique after the illumination of 375 nm laser. This photo-induced enhanced surface potential can mainta…
For the first time, comprehensive phycological screening on El-Farafra Oasis (Western Desert, Egypt) had been implemented for unveiling and characterization of its cryptic algal diversification, with special interest on springs and drilled wells. Overall during summer 2011 and winter 2012, 82 different algal taxa have…
This study investigated the glueless preparation of biomass board using rape straw on a laboratory scale. The board-making process was broken down into four steps: soaking, refining, shape recovery, and hotpressing. To observe the effect of pressure during the hot-press stage on the strength of the bio-board, five pan…
