The influence of an aromatic hydrazide derivative, 2-(3,4,5-trimethoxybenzylidene) hydrazinecarbothioamide (TMBHC) as corrosion inhibitor on mild steel in 1 M hydrochloric acid was studied by Tafel polarization and electrochemical impedance spectroscopy (EIS) technique. The results showed that the inhibition efficienc…
Biodegradable Poly(butylene succinate), PBS, was photooxidized by UV/ozone irradiation and the effect of UV energy on the surface properties of the UV-irradiated PBS film were investigated by the measurement of reflectance, surface roughness, contact angles, chemical composition, and zeta potential. With increasing UV…
Poly(vinyl alcohol)(PVA)/pullulan/titanium dioxide(<TEX>$TiO_2$</TEX>) composite nanofibers were produced at different <TEX>$TiO_2$</TEX> concentrations(1 and 3 wt.%) using the electrospinning method. The parameters of electrospinning including polymer contents, voltage and tip-to-collector distance(TCD) were optimize…
Based on density functional theory (DFT), it is shown that solvent polartity induce a modification in optical and electronic properties of a carbazole-benzothiazole bipolar compound. The first moiety is used as electron donor when the second one is considered as electron acceptor. According to theoretical results, the…
ABSTRACT Poly(vinylidene fluoride‐ co ‐trifluoroethylene‐ co ‐chlorotrifluoroethylene) (P(VDF‐ co ‐TrFE‐ co ‐CTFE)) with internal double bond has been reported with high dielectric constant and energy density at room temperature, which is expected to serve as a promising dielectric film in high pulse discharge capacit…
Titanate hollandites comprise a class of potential waste form phases for immobilization of radioactive Cs (and its daughter product Ba) due to their high thermal and aqueous stability. To study their structural behavior at high temperature, we conducted in situ neutron diffraction experiments of a representative tetra…
Polyphenols, secondary metabolites widely present in plant kingdom, are known for their positive effects on human health, such as treatments of degenerative disease and cancer. Many dietary polyphenols show anti-inflammatory, immunomodulatory and antioxidant properties and they are proposed as chemopreventive agents f…
One of the major challenges of near‐infrared upconversion photocatalyst concerns strengthening the cooperation between Rare‐earth ( RE ) ions and semiconductor materials for enhancing NIR photocatalytic activity. Herein, the basic energy‐transfer (ET) process between RE ions and semiconductor materials is discussed an…
Polymerizing nanodroplets at solid-liquid interfaces is a facile solution-based approach to the functionalization of large surface areas with polymeric lens-shaped nanostructures. In this work, we have applied a one-pot approach to obtain polymeric nanolenses with controlled sizes and densities. We take advantage of t…
A new fluidized bed thermogravimetric analyzer (FB‐TGA) was developed that introduces two major particularities: the pseudo variation of the weight of the reactor and the special strategy for gas flow rate adjustment according to temperature. A momentum balance was performed on the reactor and the pseudo variation of…
Novel fluorinated gradient copolymer was designed for smart surface with light-responsive controllable wettability and excellent stability. The switchable mechanism and physicochemical characteristics of the as-prepared surface decorated by designed polymeric material were investigated by ultraviolet-visible (UV-vis)…
We report two new amino acid based antifouling zwitterionic polymers, poly(N(4)-(2-methacrylamidoethyl)asparagine) (pAspAA) and poly(N(5)-(2-methacrylamidoethyl)glutamine) (pGluAA). The vinyl monomers were developed from aspartic acid and glutamic acid. Surface-initiated photoiniferter-mediated polymerization was empl…
BACKGROUND: Wing discs of B. mori are transformed to pupal wings during the larva-to-pupa metamorphosis with dramatic morphological and structural changes. To understand these changes at a transcriptional level, RNA-seq of the wing discs from 6-day-old fifth instar larvae (L5D6), prepupae (PP) and pupae (P0) was perfo…
Circular dichroism (CD) spectroscopy is a valuable method for defining canonical secondary structure contents of proteins based on empirically-defined spectroscopic signatures derived from proteins with known three-dimensional structures. Many proteins identified as being "Intrinsically Disordered Proteins" have a sig…
Surface-adherent polydopamine (PDA) films as multifunctional coatings can be easily deposited onto a wide range of materials through dopamine self-polymerization. However, a lack of in-depth understanding of PDA aggregation and deposition processes and definite structure elucidation of PDA make it challenging to tailo…
The (Fe,Co)-(Fe,Co)17Gd2 pseudo-binary eutectic system has been determined by investigating phase compositions on the analysis of DSC, EDS and XRD. The rapid solidification of Gd7.3Fe30.56Co62.14, Gd9Fe30Co61 and Gd9.63Fe29.79Co60.58 ternary alloys is realized by single roller techniques. With a rising cooling rate, t…
The axial sliding of carbon-based normal nanorings (NCNs) and one-turn Möbius nanorings (MCNs) along inner coaxial carbon nanotubes with hydrogen-terminated edges is described. Classical molecular dynamics simulations were carried out to investigate their sliding considering C300H100 NCN and MCN nanostructures and sin…
This paper proposes a more accurate behavioral circuit model to predict transient responses of an active-matrix liquid crystal display (AMLCD) with a patterned vertical alignment (PVA) mode. In the case of the PVA mode, we observed that simulation errors increase when the conventional circuit model is directly applied…
The fabrication of large-scale graphene nanoribbon (GNR) network and its application for gas sensing are reported. A large area, nanoscale GNR network was produced by a facile approach of silver nanowires (Ag NWs) templated graphene masking and subsequent 02 plasma etching. GNR network shows significantly enhanced sen…
We present a detailed study on trapping and releasing of light in a graded graphene-silica metamaterial waveguide. By applying proper gate voltages onto the graphene layers, the metamaterial with graded-permittivity has the ability to trap the light due to the vanishing of normalized optical power flow between forward…
