Multifunctional Fiber Sensors Demand for smart electronic textiles has led to interest in fiber-shaped sensing devices. Elastic fiber sensors offer wider strain monitoring range and adaptability. In article number 2202079, Jian Fang, Yuqing Liu, co-workers fabricate highly stretchable elastomeric fibers with copper particle-mixed liquid metal electrodes using a thermally drawn process. The comp...

shaped IUS’ Reading Dr Lloyd’s letter in the July 2013 issue of the Journal has prompted me to write in on this topic. Removal of an intrauterine device (IUD) involves traction on the threads causing the horizontal arms of the device to come together in the narrower lower half of the uterus during its downward movement. It is relatively easy for the collar of hormone in an intrauterine system (...

The theory, design, simulation, fabrication, and performance of an omnidirectional polarization detector (PD) with two resonances located in the X and Ka ranges based on a metamaterial absorber (MMA) are presented in this paper. The sandwich structure of PD is composed of 0.1 μm periodic "I" shaped patches on the metasurface, a dielectric of 200 μm FR-4 on the interlayer, and a 0.3 μm copper fi...

A unit cell based numerical approach to model the metal powders and metal-dielectric composites at microwave frequencies is proposed. The unit cell based numerical modeling helps to compute the equivalent reflection and transmission coefficients of these materials, which are commonly used measured parameters at RF and microwave frequencies. The computation of the reflection and transmission coe...

The major laccase isoenzyme LAP2 secreted by the white-rot basidiomycete Trametes pubescens in response to high copper concentrations was purified to apparent electrophoretic homogeneity using anion-exchange chromatography and gel filtration. The monomeric protein has a molecular mass of 65 kDa, of which 18% is glycosylation, and a pI value of 2.6. The pH optima of the laccase depend on the sub...

Mass transfer in porous media has been of interest to a number of researchers in the field of engineering. The transfer of substances is generally attributed to diffusion, convection of pore fluid and, in some cases, reaction with surfaces of porous media. It is difficult to understand owing to the great sensitivity to ambient conditions such as gravity, boundary geometry and fluid properties. ...

Laser ablation in an ambient gas is nowadays used in a growing number of applications, such as chemical analysis and pulsed laser deposition. Despite the many applications, the technique is still poorly understood. Therefore models describing the material evolution in time during short pulse laser irradiation can be helpful to unravel the puzzle and finally result in the optimization of the rel...

Antifouling efficacy of graphene nanowalls, i.e., substrate-bound vertically-oriented graphene nanosheets, has been demonstrated against biofilm-forming Gram-positive and Gram-negative bacteria. Where graphene nanowalls are typically prepared using costly high-temperature synthesis from high-purity carbon precursors, large-scale applications demand efficient, low-cost processes. The advancement...

Magnetic resonance imaging is a widely used technique for medical and materials imaging. Even though the objects being imaged are often irregularly shaped, suitable coils permitting the measurement of the radio-frequency signal in these systems are usually made of solid copper. One problem often encountered is how to ensure the coils are both in close proximity and conformal to the object being...
