This paper aims at the development of a proportional integral derivative (PID) controller with a derivative filter coefficient for a magnetic levitation system (MLS), which is a highly nonlinear open loop system. The mathematical modeling of MLS is done using MATLAB/Simulink. The proposed controller simulation results…
Delivery strategies for porphyrinoid-based photosensitizers for use in therapeutic applications are based on a myriad of factors, which include porphyrinoid structure, solubility and cellular targets. These drug-delivery methods include encapsulation, hydrogels, protein carriers, nanoparticles and polymeric micelles a…
In this study, we investigate the metal-insulator transition of charge transfer type in high-temperature cuprates. We first show that we must introduce a new band parameter in the three-band model to reproduce the Fermi surface of high-temperature cuprates such as BSCCO, YBCO and Hg1201. We present a new wave function…
The clinical application of small interfering RNA (siRNA) has been restricted by their poor intracellular uptake, low serum stability, and inability to target specific cells. During the last several decades, a great deal of effort has been devoted to exploring materials for siRNA delivery. In this study, biodegradable…
The conceptual design of the subcritical advanced burner reactor (SABR), a 3000-MW(thermal) annular, modular sodium pool–type fast reactor, fueled by metallic transuranic (TRU) fuel processed from discharged light water reactor fuel and driven by a tokamak D-T fusion neutron source based on ITER physics and technology…
The mechanical behavior of carbon fibers determines the applications of carbon fiber reinforced composites in automotive and aerospace. The indentation behavior of single carbon fibers has been investigated in the indentation load range of 0.5 mN to 2.5 mN on two different cross-sections; one is a longitudinal section…
Primary alcohols are selectively converted into aldehydes by using a Nb(2)O(5) photocatalyst under visible-light irradiation. A strong interaction between the alcohol and Nb(2)O(5) generates a donor level within the forbidden band of Nb(2)O(5), which provides a visible-light-harvesting ability. Over oxidation of aldeh…
INTRODUCTION: P-glycoprotein (P-gp) inhibitors are usually used to treat tumors that overexpress P-gps. However, most common types of breast cancers, such as Luminal A, are low-P-gp expressing, at least during the initial phases of treatment. Therefore, it would be interesting to know if P-gp inhibitors are still usef…
High-power steam plasma for heating the coal powders were developed, where the magnetron power at 915 MHz was available up to 75 kW. The steam plasma itself is an impedance load, which depends on physical conditions, including the microwave power. By monitoring the minimum reflected power, the optimum injection rate o…
Bamboo biomass fibers were gradually separated, prepared, and then self-plasticized for immune composites. The molecular bonding characteristics of the self-plasticized bamboo composites were investigated by Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (NMR), and thermo grav…
The mineralogy of rare earth element deposits is critical in understanding their petrogenesis and has significant implications for their economic viability, which is determined by more than ore grade alone. Rapid determination of relative ore modal mineralogy for these deposit types by hyperspectral reflectance spectr…
The systematic optimization of single-crystal fluoride-conducting solid electrolytes R 1 − y Ca y F3 − y with a tysonite type structure (LaF3) with respect to the conductivity at room temperature, σ(293 K), is based on high-temperature measurements of σ(T) of stoichiometric fluorides of rare earth elements, RF3 (R = L…
We develop a simple and fast procedure that unfolds band structures obtained from supercell calculations and which is valid for methods based on the linear combination of atomic orbitals, regardless of basis orthogonality. We show that by appropriately choosing the localized basis set, the unfolding formula reduces to…
The results have been considered of the studies of the plastic flow initiation in nanoindentation of single crystals of hard and superhard oxides. It has been found that the transition from elastic to elastoplastic deformation in superhard brittle oxides is accompanied by the formation of essentially lower number of d…
Abstract The activity of two bifunctional metal–organic frameworks (MOFs) with IRMOF‐9 topology that contain amino, phosphine oxide and methyl groups is described. The amino group acts as an active site for the Knoevenagel condensation of ortho, meta or para nitrobenzaldehyde and malononitrile, while the non‐active si…
A simple method for the counting and structural elucidation of the different active sites in an olefin polymerization catalyst system is introduced, based on a reaction quench by O2 under controlled kinetics, followed by NMR analysis of the OH‐labeled chain end‐groups formed upon acidic work‐up of the polymer. The met…
The effect of conditions of crystallization in the course of the production of a bearing lining on the structure and wear of the B83 babbit has been studied. It is shown that the pressing of the melt being crystallized makes it possible to form a homogeneous structure with fine crystals of the cubic SnSb phase. The ba…
Reducing the scale of etched nanostructures below the 10 nm range eventually will require an atomic scale understanding of the masks being used in order to maintain exquisite control over both feature size and feature density. Here, the authors demonstrate a method for tracking atomically resolved and controlled struc…
The pressure-volume equation of state for the two spinel end-member compositions chromite Fe- Cr 2 O 4 and magnesiochromite MgCr 2 O 4 was determined for flux-grown synthetic single crystals at room temperature up to 8.2 and 9.2 GPa, respectively, by single-crystal X-ray diffraction using a diamondanvil cell. The pres…
Mia40 catalyzes oxidative protein folding in mitochondria. It contains a unique catalytic CPC dithiol flanked by a hydrophobic groove, and unlike other oxidoreductases, it forms long-lived mixed disulfides with substrates. We show that this distinctive property originates neither from particular properties of mitochon…
