Keeping in shape: Polymerizable coil–rod–coil molecules self-organize into 2D columnar and 3D bicontinuous liquid crystals whose supramolecular architectures and lattice dimensions are preserved upon photopolymerization (see picture). Nanofibers resulting from the photopolymerization of the 2D structures are utilized…

Abstract Poly(2,2,2‐trifluoroethyl methacrylate) (PTFEMA), a partially fluorinated polymer, was directly grafted from silicon wafer surfaces by a surface‐initiated atom‐transfer radical polymerization (ATRP). The polymer layer thickness increased linearly with monomer conversion and molecular weight of free polymers i…

Methyl mercaptan (CH 3 SH) is a representative odorous pollutant from various odor emission sources such as sewage and municipal solid wastes. This study confirms that CH 3 SH in a synthetic foul gas can be effectively decomposed by UV-C (<280 nm) photolysis using germicidal lamps, but is resistant to destruction unde…

A new view is presented on the concept of the combined cycle for power generation. Traditionally, the term “combined cycle” is associated with using a gas turbine in combination with steam turbines to better utilize the exergy potential of the burnt fuel. This concept can be broadened, however, to the utilization of a…

Summary Calcium carbonate (CaCO3) scale is a common problem in the oil industry, leading to reduced well performance and obstruction of safety valves. Recent field experiences indicate that scaling may be a problem at lower saturation ratio (SR) than earlier anticipated. In a high-pressure, high-temperature scale cell…

PURPOSE: The incorporation of doxorubicin in long-circulating sterically stabilized liposomes (SSL-DXR) alters the pharmacokinetics and biodistribution of doxorubicin and therefore has the potential to alter the pharmacologic properties of doxorubicin. Previously, we showed that repetitive administration of SSL-DXR al…

We present a quantitative, systematic study of the effect of magnetostriction on the dynamical properties in NiFe alloys. Both the ferromagnetic resonance frequency and the damping times are correlated to the magnetostriction. In addition, we find that the Gilbert damping parameter varies by more than 100% over the ra…
