The effectiveness of coalescence-induced jumping of microdroplets on superhydrophobic surfaces is critical to a wide range of applications such as self-cleaning surfaces, anti-icing/frosting, water harvesting, phase-change heat transfer, and hotspot cooling. Introducing textures on the surfaces can readily enlarge the…
The insulation of power equipment can be effectively assessed by analyzing the acoustic signals originated from partial discharges (PD). Fabry-Perot (F-P) sensors are capable of detecting PD acoustic signals. Although the frequency bandwidth of an F-P sensor is mainly referred to conventional piezoelectric transducer…
Abstract In this work, the preparation of conducting polymer‐based composites using a biological anionic polymer based on salmon deoxyribonucleic acid (DNA) is presented. The most commonly used polymers poly(3,4‐ethylenedioxythiophene) (PEDOT), as well as polypyrrole, are polymerized in the presence of DNA. Since conj…
Carbon nanohorns (CNH) have been considered potential anticancer drug carriers, such as the cisplatin drug (cddp), due to their low toxicity, high purity, drug-loading capacity, and biodegradation routes. However, when it comes to nanomedicine applications, chemical functionalization is an essential step in order to o…
Dual phase (DP) steels have a great deal of importance in the automotive industry. These steels are used to fabricate structural parts of vehicles with the goal of passenger safety. In this study, the corrosion properties of DP 600 and 800 steel in 3.5 wt.% NaCl environment were evaluated using electrochemical impedan…
Abstract Colloidal PbS quantum dots (QDs) have provoked a revolution in the field of optoelectronic devices owing to their low‐cost fabrication processing and excellent physical properties. Recently, the fabrication of nanostructured PbS QD photovoltaic (PV) devices based on zinc oxide (ZnO) nanowire array appears as…
Indigoid chromophores have emerged as versatile molecular photoswitches, offering efficient reversible photoisomerization upon exposure to visible light. Here we report synthesis of a new class of permanently charged hemiindigos (HIs) and characterization of photochemical properties in gas phase and solution. Gas-phas…
The nature of starting materials and the condition of polyurethane (PU) preparation are regarded as the main general parameters that determine PU thermal resistance. The effect of structure and presence of additives were identified as the major general factors on this regard. Structural factors include phase microstru…
How to prevent the agglomeration of nanoparticles in nanocomposites remains a key challenge. Using nanometer suspension as a doping agent provides an effective approach to solve this challenge. A new technique that consists of chemical coprecipitation, ball milling and sedimentation separation metheds was developed fo…
By using full-potential linearlized augumented method with GGA and GGA+U approximations, the structural, elastic, electronic, magnetic and transport, along with optical properties of Ba 2 TmSbO 6 have been evaluated. The calculated properties consent with experimental outcome which entails credibility of current study…
Bi2Te3 thin films were deposited onto polyamide sheets with direct current (DC) or radio frequency (RF) magnetron sputtering techniques. The films were prepared using a Bi2Te3 target at a varying pre-heating temperature from 150 to 350 °C. It was observed that the type of plasma excitation and pre-heating temperature…
Abstract Herein, a simple and facile two-step sonication method was developed for the preparation of nanosheets-like MoS 2 wrapped graphene nanohybrids for energy storage and hydrogen evolution reaction (HER) applications. TEM and HR-TEM images revealed that the 120 nm sized lateral diameter of sheet-like MoS 2 was co…
Using density functional theory (DFT) technique, we explored the interaction behaviour of target chloroform (CHCl3) molecules on armchair blue phosphorene nanoribbon (ABPNR). Besides, van-der-Waals dispersion correction (vdW-DF) density functional is included in the adsorption studies for accurate calculation. The mos…
Directional solidification experiment was carried out with Al-Bi-Sn immiscible alloy under microgravity environment onboard the Tiangong 2 space laboratory of China. Sample with a well-dispersed microstructure was obtained by properly designing the experimental scheme, the matrix shows equiaxed morphology, and there i…
Collagen is the most abundant protein family in the animal kingdom. Its structural motif envisages three polypeptide chains coiled in the so-called collagen triple helix. Depending on the triplet amino acid sequence of the chains, collagen has different helical arrangements. Such atomic-scale structural variations hav…
Abstract A new type of supported vanadium phosphorus oxide (VPO) with self-phase regulation was simply fabricated (organic solvent free) for the first time by depositing the specific VPO precursor NH 4 (VO 2 )HPO 4 onto the Siliceous Mesostructured Cellular Foams (MCF) with controlled activation. The resulting materia…
This work uses theoretical calculations to discover the potential application of CCOFs in gas adsorption and separation, and conduct theoretical research.
Supercontraction is one of the most interesting properties of spider dragline silks. In this study, changes in the secondary structures of the Nephila edulis spider dragline silk after it was subjected to different supercontraction processes were investigated by integrating synchrotron Fourier transform infrared (S-FT…
DegP, a periplasmic dual-functional protease and chaperone in Gram-negative bacteria, is critical for bacterial stress resistance, but the precise underlying mechanisms are not fully understood. Here, we show that the protease function of DegP is critical for Escherichia coli cells to maintain membrane integrity, part…
Abstract Electrolyte gating, based on the electric double‐layer effect, has been widely used for 2D layered materials (2DLMs), since it is capable of inducing an ultrahigh charge‐carrier density while requiring only a low gate voltage. However, the wafer‐scale fabrication of high‐performance field effect transistors (…
