The reinforced concrete beam-column joint exhibits different properties under dynamic loading when compared with that under quasi-static loading, due to the effect of strain rate. However, the majority of previous studies are focused more on the rate effect of concrete and reinforcement, but less on beam-column joints…
The development of therapies that lead to the regeneration or functional repair of compromised cardiac tissue is the most important challenge facing translational cardiovascular research today. During the last 25 years huge efforts have been made towards restoring the physiologic functions of the heart by means of del…
We report a systematic and quantitative study of near-infrared intersubband absorption in strained AlGaN/GaN and lattice-matched AlInN/GaN superlattices grown by plasma-assisted molecular-beam epitaxy as a function of Si-doping profile with and without \ensuremath{\delta} doping. For AlGaN/GaN, we obtained good theore…
The ultimate miniaturization of electronic devices at the atomic scale with single electrons requires controlling the reversible charge storage in a single atom. However, reversible charge storage is difficult to control as usually only one charge state can be stabilized. Here, combining scanning tunneling microscopy…
Dicarboxylate supported metal organic hybrids of Co(II), Zn(II) and Cd(II) have been synthesized using two different pyridyl based N,N′ linkers having Schiff base functionalized site. The use of flexible dicarboxylate glutarate in designing such frameworks has created a marked diversity in topology. The different N,N′…
The crystal structure of La10W2O21, which has to be reformulated (La5.667W0.333)LaWO14□2, is best described, on average, by a 2 × 2 × 2 anion-deficient fluorite-related superstructure cubic cell, with space group F4 3m, Z = 4, and a = 11.17932(6) Å, similar to Y7ReO14--δ. The 32 cations are distributed with lanthanum…
We analyse the combinatorial aspect of global optimisation for multicomponent systems, which involves searching for the optimal chemical ordering by permuting particles corresponding to different species. The overall composition is presumed fixed, and the geometry is relaxed after each permutation in order to relieve…
Prediction of protein loop conformations without any prior knowledge (ab initio prediction) is an unsolved problem. Its solution will significantly impact protein homology and template-based modeling as well as ab initio protein-structure prediction. Here, we developed a coarse-grained, optimized scoring function for…
The encapsulation of curcumin using p-sulfonatocalix[4]arene (p-SC4) is an attempt to increase the bioavailability of curcumin by increasing water solubility. The degradation of curcumin due to the basicity of p-SC4 is circumvented by maintaining the pH at 3 using 2% hydrochloric acid. The interaction is studied using…
Flexible organic field-effect transistors (OFETs) are fundamental elements for the development of rollable displays, flexible circuits, and bio-compatible sensors. Although single-crystalline organic nanostructures show great promise for the construction of high-performance OFETs, their applications in flexible device…
A new magnetic catalyst was synthesized by the immobilization of vitamin B1 (thiamine hydrochloride) on the surface of silica-encapsulated γ-Fe2O3 nanoparticles. Its capability was evaluated in the acylation of alcohols and phenols with acetic anhydride under solvent-free conditions and afforded the desired products i…
Quantum information can be protected from decoherence and other errors, but only if these errors are sufficiently rare. For quantum computation to become a scalable technology, practical schemes for quantum error correction that can tolerate realistically high error rates will be necessary. In some physical systems, e…
The effect of the electrode potential in the reactivity of platinum stepped single crystal electrodes with (111) terraces toward CO oxidation has been studied. It is found that the CO adlayer is significantly affected by the potential at which the adlayer is formed. The electrochemical and FTIR experiments show that t…
Palladium nanoparticles supported on carbon black (Pd/C) have been successfully synthesized in a dispersion of sodium hydroxide, ethylene glycol, and carbon black (NaOH/EG/C) at room temperature without any protection with an inert gas atmosphere. Carbon black and EG dehydrated by NaOH (0.02 M) synergistically reduce…
Despite the high π-acidity of thioether donors, ruthenium(II) complexes with a bidentate 1,2-bis(phenylthio)ethane (dpte) ligand and two chelating diimine ligands (i.e., Ru(diimine)2(dpte)(2+)) exhibit room-temperature fluid solution emission originating from a lowest MLCT excited state (diimine = 2,2'-bipyridine, 5,5…
A comprehensive experimental study is reported on the optical and electrical characteristics of 2-((5-(4-(diphenylamino)phenyl)thiophen-2-yl)methylene)malononitrile (DPTMM) when used as molecular donor in an organic solar cell (OSC) device structure. A major property of this new donor-type material is an unusually dee…
Nanoparticle superlattices are key to realizing many of the materials that will solve current technological challenges. Particularly important for their optical, mechanical or catalytic properties are superlattices of anisotropic (nonspherical) nanoparticles. The key challenge is how to program anisotropic nanoparticl…
We propose a device that allows for the emission of pairs of spin-polarized electrons into the edge states of a two-dimensional topological insulator. Charge and spin emission is achieved using a periodically driven quantum dot weakly coupled to the edge states of the host topological insulator. We present calculation…
Monoclonal antibodies (mAbs) or their derivatives are often used as the targeted ligands in the ligand targeted liposomes (LTLs). LTLs modified with mAbs or their derivatives are defined as immunoliposomes. Immunoliposomes can be designed to improve the pharmacological properties of conventional drugs. The development…
A self‐designed experiment circuit was adopted to investigate the effect of alternating current (AC) on corrosion rate and cathodic protection (CP) potential of cathodically protected Q235 steel in the simulated soil solution of 4 g/L sodium sulfate. It is found that the corrosion induced by AC current can be controll…
