The solubility data for sodium halides (NaF, NaCl, NaBr, and NaI) have been determined at 298.15 K in the ε-increasing mixtures of water–formamide, water– N -methylformamide, and water– N -methylacetamide. In all cases, the solubility of the electrolytes was decreased significantly in the presence of a cosolvent. The…
An organic field-effect transistor (OFET) toward phosphate sensing has been successfully developed. The fabricated OFET possessing an extended-gate functionalized with zinc(II)–dipicolylamine (ZnII–DPA) exhibited an electrical and cross-reactive response to phosphate anions such as nucleotides and inorganic phosphates…
Spontaneous resolutions from an in situ reaction especially for a Sharpless reaction are really rare. Here we display a new pair of enantiomeric compounds Δ - and Λ - [Mn(4-tzba)(bpy) 2 ·H 2 O](bpy)·3H 2 O (labeled as Δ -1 and Λ -1 respectively) (4-tzba = 4-tetrazolbenzoic acid; bpy = 2,2′-bipyridine) from a Sharpless…
Abstract The pre–thermal–quench (PTQ) phase of the massive gas injection (MGI) scenario to terminate the tokamak plasma discharge is studied by means of one-dimensional (1D) transport simulations. This phase is characterized by the cold–front penetration in the hot plasma after the gas has been released from the valve…
The Cu(OAc)2-mediated intermolecular diamination reaction of C60 with ureas allows the concise and efficient preparation of fulleroimidazolidinones involving the cleavage of two N-H bonds and formation of two C-N bonds. Both dialkylated and diarylated fulleroimidazolidinones can be synthesized using this method.
The magnetic shielding device causing only negligible distortion of external magnetic field is called the magnetic cloak. We have designed and tested cloaks with a coaxial bilayer structure where a superconducting cylindrical layer is placed inside the tube from a ferromagnetic material. Such object when inserted in t…
Exciton dynamics in π-conjugated molecular systems is highly susceptible to conformational disorder. Using time-resolved and single-molecule spectroscopic techniques, the effect of chain length on the exciton dynamics in a series of linear oligothiophenes, for which the conformational disorder increased with increasin…
The organic-inorganic hybrid crystal Ni(en)3Ag2I4 (where en represents 1,2-ethylenediamine) crystallizes in hexagonal space group P63, in which the AgI4(3-) tetrahedra connect into a diamondlike inorganic framework via sharing of the vertex and the Ni(en)3(2+) octahedra fill in the pores of the framework. UV-vis-near-…
Abstract Understanding the mechanism of resistive switching in a memory device is fundamental in order to improve device performance. The mechanism of current switching in a basic organic write-once read-many (WORM) memory device is investigated by determining the energy level alignments of indium tin oxide (ITO), pol…
A characteristic magnetic separation technique has been developed to recycle the Ni resource from the waste fluid of electroless Ni-plating processes. Since the plating waste still contains high concentration of Ni ions after several cycles of plating processes, the magnetic separation experiments were conducted to co…
Abstract The new nitridoborate nitride Mg3Ga(BN2)N2 was prepared by multilateral solid‐state metathesis reaction from MgCl2, GaN, Li3N, and Li3BN2 at high temperature. The crystal structure of Mg3Ga(BN2)N2 was refined from X‐ray powder diffraction patterns isotypically to Mg3Al(BN2)N2 with the space group R$\bar {3}$…
BACKGROUND: This study was to investigate the effect of collagen grafted porous biphasic calcium phosphate (BCP) on cell attachment, proliferation, and differentiation. Porous BCP scaffolds with interconnected micropore structure were prepared with were prepared and then grafted with a collagen type I. The hydroxyapat…
Poly(arylene ether sulfone) (PES)–titanium dioxide (TiO 2 ) hybrid membranes were prepared via solution blending method using TiO 2 nanoparticles as inorganic filler. The chemical structure and thermal stability of the matrix polymer were characterized by proton nuclear magnetic resonance, Fourier transform infrared,…
The processing of an originally non-porous 1D coordination polymer as monolithic gel, xerogel and aerogel is reported as an alternative method to obtain novel metal-organic porous materials, conceptually different to conventional crystalline porous coordination polymer (PCPs) or metal-organic frameworks (MOFs). Althou…
Salt-bridge interactions play an important role in stabilizing many protein structures, and have been shown to be designable features for protein design. In this work, we study the effects of non-native salt bridges on the folding of a soluble alanine-based peptide (Fs peptide) using extensive all-atom molecular dynam…
Abstract Effects of ultrasonic nanocrystal surface modification (UNSM) on the very high cycle fatigue response of AISI 310 stainless steel have been investigated. The higher impact force used in UNSM treatment showed a higher fatigue life improvement. The fatigue life improvement was higher in crack initiation from th…
In this paper, a naphthalene (C 10 H 8 ) thermal cracking model is presented. The model is based on a simple model that takes into account the microwave (MW) plasma thermal influence on naphthalene cracking, accompanying its steam reforming reactions. The temperature level of 1573 K was established for complete C 10 H…
A practical anodic and cathodic curve intersection model, which consisted of an apparent anodic curve and an imaginary cathodic line, was proposed to explain multiple corrosion potentials occurred in potentiodynamic polarization curves of Fe-based glassy alloys in alkaline solution. The apparent anodic curve was selec…
Abstract The rational design of catalytic materials from the reaction characteristics is expected to be a useful strategy to create highly efficient catalysts. Herein, according to a well‐established reaction pathway of epoxide hydration catalyzed a dual‐molecular system of Co3+/salen in which a high concentration of…
