Protein therapy, wherein therapeutic proteins are delivered to treat disorders, is considered the safest and most direct approach for treating diseases. However, its applications are highly limited by the paucity of efficient strategies for delivering proteins and the rapid clearance of therapeutic proteins in vivo af…
Acyltransferases (ATs) are key determinants of building block specificity in polyketide biosynthesis. Despite the importance of protein-protein interactions between AT and acyl carrier protein (ACP) during the acyltransfer reaction, the mechanism of ACP recognition by AT is not understood in detail. Herein, we report…
In the present study, hydrodynamic (HD) cavitation was combined with sodium percarbonate (SP) for the pretreatment of lignocellulosic biomass. For HD cavitation, a circular flow system equipped with a venturi tube was employed. The combined system of HD and SP (HD-SP) was compared to a pretreatment system using ultras…
Frequency response analysis (FRA) has been globally accepted as a reliable tool to detect mechanical deformation within power transformers. However, because of its reliance on graphical analysis, interpretation of FRA signature is still a challenging area that calls for skilled personnel, as so far, there is no widely…
The memtranstor has been proposed to be the fourth fundamental circuit memelement in addition to the memristor, memcapacitor, and meminductor. Here, we demonstrate the memtranstor behavior at room temperature in a device made of the magnetoelectric hexaferrite (Ba 0.5 Sr 1.5 Co 2 Fe 11 AlO 22 ) where the electric pola…
LiCoMnO 4 materials have been synthesized via a hydrothermal approach followed by a post-annealing process. Pure phase of LiCoMnO 4 is unable to form under hydrothermal conditions; however, high quality of pure LiCoMnO 4 was achieved after annealing the hydrothermal products. The concentration of LiOH and the post-ann…
Owing to the very high cost of conventional filler materials in polymer composites, exploring the possibility of using low cost minerals and industrial wastes for this purpose has become the need of the hour. In view of this, the present work includes the development and the wear performance evaluation of a new class…
Fiber-reinforced concrete is designed on composite binder. At 1.6% of reinforcing steel anchoring fiber maximum physical and mechanical properties (R compr = 100.9 MPa) can be obtained. It was found that the combined effect of mechanical and chemical activation (the presence of limestone particles) increases the pozzo…
The phenomenon of the motor oil viscosity stratification in lubricating the cylinder-piston units of marine diesel engines has been investigated. The correlations for determining the shear stress and the velocity, occurring in the liquid flow between the parallel planes, have been given. The modes of the hydrodynamic…
The authors developed a seed-mediated method by GeO2 nano-particles (NPs) for growing crystal perovskite films. Poly(3,4-ethylene dioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS)-GeO2 composite films can act as an efficient underlayer for the growth of crystal perovskite films. GeO2 NPs are regarded as the growing…
The possibility of forming a microprofile in diffractive optical elements by thermal oxidation of thin molybdenum films is analyzed. It is shown that the gain in the thickness of a starting film in the thermal oxidation process may reach a threefold value, with the optical quality of the surface preserved.
AlN substrate is widely used along with silicone gel to encapsulate power electronic circuits. It is known that the weakness of the insulation system is surface discharges propagating at the gel-substrate interface. In this research, the nature of surface discharges in gel, on various substrates was investigated. The…
A systematic study of the ion beam heating effect was performed in a temperature range of -170 to 900 °C using a 10 MeV Au(3+) ion beam and a Yttria stabilized Zirconia (YSZ) sample at a flux of 5.5 × 10(12) cm(-2) s(-1). Different geometric configurations of beam, sample, thermocouple positioning, and sample holder w…
In this study the effect of pore structure on the mechanical properties and durability characteristics of Self-Compacting Mortars (SCM) containing nano-Al2O3 (NA) and class F fly ash are investigated. Al2O3 nanoparticles with the maximum size of 15 nm in three different proportions of 1, 3 and 5% of the binder content…
This paper covers the effect of heat treatment on the mechanical properties of medium carbon steel. The main objective of this project is to investigate the hardness and impact properties of medium carbon steel treated at different heat treatment processes. Three types of heat treatment were performed in this project…
Recently, nanomaterials with multiple functions, such as drug carrier, magnetic resonance imaging (MRI) and optical imaging, and photothermal therapy, have become more and more popular in cancer research. In this work, a novel redox-sensitive system constructed from hyaluronic acid (HA), single-walled carbon nanotubes…
Abstract Shark skin surfaces of fast‐swimming sharks are characterized as non‐smooth because of the presence of dermal denticles or riblet structures and exhibit an excellent drag‐reduction effect. A review of the surface morphology, structure and mechanical behaviors of shark skin is given. Investigations into the mi…
Thermal information processing is attracting much interest as an analog of electronic computing. We experimentally demonstrated a radiative thermal memory utilizing a phase change material. The hysteretic metal-insulator transition of vanadium dioxide (VO2) allows us to obtain a multilevel memory. We developed a Preis…
Abstract Individual impurity atoms in silicon can make superb individual qubits, but it remains an immense challenge to build a multi-qubit processor: there is a basic conflict between nanometre separation desired for qubit–qubit interactions and the much larger scales that would enable control and addressing in a man…
The novel ambipolar hosts of o-CbzBz and o-DiCbzBz contain carbazole and benzimidazole through an ortho-connection. The orthogonal conformations cause the triplet state to be confined at the carbazole units to secure efficient energy transfer. The phosphorescent organic light-emitting diodes (PhOLEDs) show a high curr…
