Effect of calcareous sediments on hydrogen evolution potential which formed under different cathodic protection potentials was investigated in this paper. Electrochemical impedance spectroscopy (EIS), potentiodynamic polarization and hydrogen permeation experiment were carried out to analyze the electrochemical proper…
A constitutive model is critical for the prediction accuracy of a metal cutting simulation. The highest strain rate involved in the cutting process can be in the range of 104–106 s–1. Flow stresses at high strain rates are close to that of cutting are difficult to test via experiments. Split Hopkinson compression bar（…
Although carbon nanotubes (CNT) have been employed as reinforcements in nanocomposites, presence of nano scale defects such as Stone-Wales and vacancy defects in carbon nanotubes (CNT) weakens the mechanical properties of these materials. In this paper the effects of defects in CNTs on nanocomposite elastic behavior a…
Six typical pedons collected from Dahingapar (P1), Kotalgorie (P2), Baideha (P3), Neghareting (P4), Chenijan (P5) Tea Estates of Jorhat district and Thurajan Tea Estate (P6) of Golaghat district, representing gently to moderately sloping upland in upper Brahmaputra valley of Assam were studied for their characteristic…
Corrosion inhibition of mild steel using a new ternary formulation, Urea, Zn (II) and L-Alanine in sulphuric acid medium at pH-4 was studied by weight loss and electrochemical studies. The inhibition efficiency increases with increasing concentration of inhibitors. The electrochemical impedance spectroscopy results sh…
Abstract Ruthenium(II) complex with the phosphonate anchoring groups of [Ru(tbbpy)
The possibility of complex formation by short lysine brush and therapeutic Semax peptides was investigated using molecular dynamics method. Lysine dendrimers and polymer brushes are used for drug and other (e.g., DNA, peptides, and polysaccharides) molecules delivery to different target cells. It is known that they co…
The change in hydrogen thermal desorption characteristic of heat resistant ferritic stainless steel (18Cr-2.5Si steel) due to creep was investigated to examine the applicability of hydrogen as a tracer for creep damage evaluation. The hydrogen charging into the interrupted creep specimens with a wide variety of damage…
An alternative approach to fabricate specialty MEMS devices by heterogeneous integration of dissimilar materials such as PCB substrates and neodymium magnets with anodic aluminum oxide (AAO) templates was demonstrated. The importance of the use of copper metal as an intermediate layer for wet chemical etching of AAO t…
Amphiphilic Janus particles self-assemble into complex metastructures, but little is known about how their assembly might be modified by weak interactions with a nearby biological membrane surface. Here, we report an integrated experimental and molecular dynamics simulation study to investigate the self-assembly of am…
projectiles with entirely predictable kinematics. While its relation to thermal catalysis may be tenuous, dynamic HNO formation could be important on grain surfaces of interstellar or cometary matter under astrophysical conditions.
Four new nickel bis(dithiolene) complexes were synthesized and characterized. The UV-vis-NIR spectra and DFT calculations indicate that their HOMO and LUMO energy levels are highly depended on the donating/withdrawing abilities of their substituents.
A new synthetic route for hollow mesoporous zinc silicate and silica nanoparticles is developed using a dual surfactant system.
Upconversion luminescence properties were investigated by emission intensity <italic>vs.</italic> excitation power (double logarithmic relationship) and temperature dependent emission spectroscopy.
Four new silver phosphonates with interesting structures and luminescent properties have been hydrothermally synthesized and systematically characterized.
A free energy expression is proposed that describes the isotropic-nematic binodal concentrations of hard rods. A simple analytical form for this free energy was yet only available using a Gaussian trial function for the orientation distribution function (ODF), leading, however, to a significant deviation of the predic…
The nanocomposite Co <sub>3</sub> O <sub>4</sub> /CoFe <sub>2</sub> O <sub>4</sub> heterostructured material was produced <italic>via</italic> a simple solid–solid reaction of an iron precursor with urchin-like Co <sub>3</sub> O <sub>4</sub> . The nanocomposite behaves as an exchange coupled system with a cooperative…
Lamellar-forming PMAPOSS-b-PTFEMA block copolymers with unimodal GPC chromatograms were successfully synthesized by the polymerization of TFEMA in the presence of PMAPOSS as a macro-RAFT agent and AIBN as the initiator via RAFT. The SAXS, AFM and GISAXS data showed the lamellar domain was perpendicularly oriented to t…
A high-grade cubic ZnS substrate crystal with longer range order and a strong band-edge emission was clearly demonstrated.
A new hybrid film with homogeneous morphology is fabricated and exhibits excellent second nonlinear optical properties.
