A polymer-drug conjugate was developed by conjugating doxorubicin (DOX) to [alpha],[beta]-poly[(2-hydroxyethyl)-L-aspartamide] (PHEA) with a succinic spacer. The suitability of PHEA-DOX in intraperitoneal chemotherapy was investigated both in vitro and in vivo. The results showed that the release rate of DOX from PHEA…
The viscosity-temperature relationship obtained by us for several glasses over a wide temperature range was analyzed by extending the Adam-Gibbs theory to the range below the glass transition temperature (T(g)). The entropy change of the intermediate-range orders (IROs) is discussed on the basis of the theory develope…
The dynamic behavior of the single-crystal Al under [001] uniaxial strain is simulated by classic molecular dynamics. The fcc–hcp structural transition is successfully observed when the loading pressure reaches about 90 GPa, and the reverse transition is also found with hysteresis. The mechanism and morphology evoluti…
Shape memory polymers (SMPs) are an emerging class of active polymers that have dual-shape capability, and are therefore candidate materials for multifunctional reconfigurable structures (i.e., morphing structures). However, the SMPs have not been fully tested to work in relevant environments (variable activation temp…
We synthesized bulk isotropic and anisotropic Nd13.5Fe77.5Co3B6and Nd13.5Fe76.5Co3Zr1B6magnets by spark plasma sintering (SPS). For hot-pressed magnets, the values of remanence (Br) and coercivity (Hci) decreased with addition of Zr. After hot-deformation, it was difficult to obtain the desired alignment for Nd13.5Fe7…
A mathematical model of measuring transmittance of infrared (IR) radiation through fabric is presented here. Combined with a specially made blackbody, a Fourier transform infrared (FT-IR) spectral radiometer was developed to measure the transmittances of polyester (PET) and cotton fabrics within the range of 8—14 µm a…
Abstract The influence of the doping level in the formation of specific interactions between plasmid DNA and PEDOT is investigated using experimental assays and theoretical calculations. Electrochemical methods are used to prepare polymer samples with oxidation degrees ranging from 0.14 to 1.05 positive charges per re…
The configurational heat capacity, shear modulus and shear viscosity of a series of Na 2 O–Fe 2 O 3 –Al 2 O 3 –SiO 2 melts have been determined as a function of composition. A change in composition dependence of each of the physical properties is observed as Na 2 O/(Na 2 O + Al 2 O 3 ) is decreased, and the peralkalin…
The size and doping dependence of the electron-hole exchange interaction in Si nanowires is investigated from first principles. In pure Si nanowires we found excitonic exchange splittings in very good agreement with the experimental results for porous silicon. For $n$-doped Si nanowires a giant singlet-triplet splitti…
The structural and dynamical properties of macromolecules in confining or crowded environments are different from those in simple bulk liquids. In this paper, both the conformational and diffusional dynamics of globular polymers are studied in solutions containing fixed spherical obstacles. These properties are studie…
The leakage current measurements on standard post insulators and on rod insulators without sheds were carried out. The porcelain and silicone rubber insulators were tested at the Glogow station under the voltage of 75 kV. It was shown that the currents on porcelain insulators are sometimes greater than the currents on…
Structure property correlation is a critical textile research area explored by various researchers and many factors have been proposed over the years to predict/compare/design the woven fabrics. Cross-over firmness factor (CFF) and floating yarn factor (FYF) have been recently proposed as parameters to understand weav…
The quantum mechanics/molecular mechanics ONIOM calculations have been performed to study the structure and metal-ion binding properties of all-trans cyclo[1R-3S-gamma-Acc-Gly]3 hexapeptide nanotube (TAG)3PNT. The intersubunit distances and tube angle of (TAG)3PNT exhibited the sturdy nature of (TAG)3 stacks upon Li+…
Abstract This study described fabrication, characterization, and application of multilayer films based on layer‐by‐layer assembly of ferrocene poly(ethylenimine) and gold nanoparticles. Assembly process of the multilayer film was investigated by atomic force microscopy, UV‐visible absorption spectroscopy and electroch…
The aim of this study is to investigate the effect of acrylic acid (AA) content of ethylene—acrylic acid copolymers (EAA) and pH level of filler particles on reinforcement of peroxide-cured ethylene—propylene—diene rubber (EPDM)/samarium borate (SmBO 3 ) and EPDM/ Sb-doped SnO 2 (ATO) composites. It was found that EAA…
Magnesium hydroxide and huntite hydromagnesite were used in halogen free flame retardant (HFFR) compounds based on blends of ethylene vinyl acetate and low density polyethylene. The effect of both cross-linking with electron beam (EB) and the introduction of nano-filler on flammability were investigated. The developed…
Molecular photoswiches are important for the development of advanced materials and molecular electronics devices. The dihydroazulene (DHA) is a particularly attractive molecule as it undergoes a light-induced ring opening to a vinylheptafulvene (VHF) isomer with altered optical properties. While functionalization of t…
Plasma-enhanced chemical vapor deposition (PECVD) technology was considered as an excellent thin film deposition dry process in semiconductor device fabrication. Porous SiO 2 film as a promising thermal insulation layer used in uncooled infrared detectors was grown directly by PECVD technology. The microstructure and…
Abstract The mineral gerstleyite is described as a sulfosalt as opposed to a sulfide. This study focuses on the Raman spectrum of gerstleyite Na 2 (Sb,As) 8 S 13 ·2H 2 O and makes a comparison with the Raman spectra of other common sulfides including stibnite, cinnabar and realgar. The intense Raman bands of gerstleyi…
Abstract Poly(3‐hydroxybutyrate) (PHB) is a very promising biopolymer. In order to improve its processability and decrease its brittleness, PHB/elastomer blends can be prepared. In the work reported, the effect of the addition of a rubbery phase, i.e. ethylene–propylene–diene terpolymer (EPDM) or poly(vinyl butyral) (…
