Fluorescent silver nanoclusters (Ag NCs) as novel fluorophores have received much attention because of their high brightness, good photostability and widely tunable emissions from the visible to the near-infrared range as a result of their size and existing environment. However, efforts are still needed to find the fa…
A novel betaine type asphalt emulsifier 3-(N,N,N-dimethyl acetoxy ammonium chloride)-2-hydroxypropyl laurate was synthesized after three steps by the reaction of lauric acid, epichlorohydrin, dimethylamine and sodium chloroacetate. The optimum reaction conditions were obtained for the synthesis of the first step of 3-…
Structure validation has become a major issue in the structural biology community, and an essential step is checking the ligand structure. This paper introduces MotiveValidator, a web-based application for the validation of ligands and residues in PDB or PDBx/mmCIF format files provided by the user. Specifically, Moti…
Atomic diffusion is a fundamental process that dictates material science and engineering. Direct visualization of atomic diffusion process in ultrahigh vacuum in situ TEM could comprehend the fundamental information about metal-semiconductor interface dynamics, phase transitions, and different nanostructure growth phe…
A novel method for the investigation of the chain‐end structure of poly(1,3‐pentadiene)s synthesized using the CF 3 COOD/TiCl 4 initiating system is developed. It is shown for the first time that the content of trans ‐1,2‐structures in the first monomer unit is considerably higher than the content of trans ‐1,4‐struct…
The prior β grain structure and orientations in the central stir zone of friction stir-processed Ti-6Al-4V were reconstructed from measured α phase orientations obtained by three-dimensional serial sectioning in a dual-beam focused ion beam scanning electron microscope. The data were processed to obtain the α colony a…
The evolution of phase segregation in stoichiometric quenched AgPb m SbTe 2+ m ( m = 18, L ead– A ntimony– S ilver– T ellurium – LAST‐18) compounds was studied starting from the known pseudo‐binary diagrams among Ag 2 Te, PbTe, Sb 2 Te 3 and AgSbTe 2 . The compositions of secondary phases indicate that liquid phase du…
According to the microwave transmission principle and the mechanism of ferromagnetic resonance, a generalized lumped element model for electrically and magnetically magnetoelectric tunable microwave devices with multi-magnetoelectric laminates is established. This model is introduced the RLC series resonant circuit an…
In order to explain clearly the role of the open boundary conditions (OBCs) on phase transition in one dimensional system, we consider an Ising model with both short-range (J) and long-range (G) interactions, which has allowed us to study the cooperative nature of spin-crossover (SCO) materials at the nanometer scale.…
Redox‐active polymers became the focus of attention in the field of organic electronics during the last decade. Quinoide systems are intensively studied in this field. Although benzoquinones are generally known as radical scavengers, certain monomers can be polymerized by radical polymerization techniques. For this pu…
Abstract In protecting themselves against different dangerous and noxious factors at the workplace, workers are often faced with the necessity of using footwear that puts a significant strain on the human body. Such footwear is frequently not accepted by the users due to wearing discomfort and difficulties with perfor…
We measured the in-plane resistivity anisotropy in the underdoped ${\text{Ca}}_{1\ensuremath{-}x}{\text{Na}}_{x}{\text{Fe}}_{2}{\text{As}}_{2}$ single crystals. The anisotropy (indicated by ${\ensuremath{\rho}}_{\mathrm{b}}\ensuremath{-}{\ensuremath{\rho}}_{\mathrm{a}}$) appears below a temperature well above magnetic…
This paper describes the photochemical tuning of net charge that develops from contact electrification. The net charge separation and/or rate of charging of photochromic spiropyran (SP)-containing polymer films can be controlled by irradiation with UV light. The isomerization of the SP form to the more hydrophilic mer…
The effects of rare earth addition on the resistance to pitting corrosion of spring steel used in fasteners of high-speed railway were investigated by metallographic examination, potentiostatic polarization tests, and SEM–EDS analysis. The addition of Ce in spring steel resulted in the formation of rare earth oxides a…
Nanomagnetic materials offer exciting avenues for advancing cancer therapies. Most researches have focused on efficient delivery of drugs in the body by incorporating various drug molecules onto the surface of nanomagnetic particles. The challenge is how to synthesize low toxic nanocarriers with multi-target drug load…
The resonant magnetoelectric coupling behavior in a Terfenol-D/PZT/Terfenol-D laminated composite structure is experimentally studied with specific interest in the dependence on the pre-applied low-level mechanical stress up to 1.25 MPa. A laminated composite consisting of two Terfenol-D plates and one transversely po…
“This book contains overviews on technologically important classes of glasses, their treatment to achieve desired properties, theoretical approaches for the description of structure-property relationships, and new concepts in the theoretical treatment of crystallization in glass-forming systems. It contains overviews…
Abstract Molded flexible polyurethane (PU) foams were synthesized from a starch/petroleum based polyol, 2,4/2,6-toluene diisocyanate (TDI-80), using a one shot method with water as the blowing agent. The effects of chain extender type [starch (S series), diethanolamine (DEA, D series), glycerol (G series)] and content…
A series of telodendrimer (a linear polyethyelene glycol-block-dendritic oligo-cholic acid) have been synthesized via a bottom-up approach to optimize the hemocompatibility of the nanocarrier. Numbers of hydrophilic glycerol groups were introduced onto the polar surface of cholic acid to reduce the plasma membrane lyt…
The epoxy resin used as the bonding agent in carbon fiber-reinforced polymer (CFRP) strengthening systems was modified by the infusion of multiwalled carbon nanotubes (MWCNTs). Two types of surfactants, Triton X-100 and C12E8, were used to disperse the nanotubes in the epoxy resin employing ultrasonic mixing. Dynamic…
