To prevent serious electromagnetic interference, a single-layer and double layer wave-absorbing coating employing complex absorbents composed of carbon black with epoxy resin as matrix was prepared. The morphologies of carbon black /epoxy composites were characterized by scanning electron microscope  and atomic force microscope, respectively. The carbon black  particles exhibit obvious polyarom...

The reduced graphene oxide (RGO)/carbon double-coated 3-D porous ZnO aggregates (RGO/C/ZnO) have been successfully synthesized as anode materials for Li-ion batteries with excellent cyclability and rate capability. The mesoporous ZnO aggregates prepared by a simple solvothermal method are sequentially modified through distinct carbon-based double coating. These novel architectures take unique a...

Barium enemas are one of the most commonly requested radiological examinations. Here in Bristol the enemas are carried out in double contrast, which is becoming widely accepted as the standard examination of the colon (Thoeni and Margulis 1978). However there are several problems which have to be overcome if an optimal double contrast examination is to be obtained. The colon must be free of its...

A β-Ta nanocrystalline coating was engineered onto a Ti-6Al-4V substrate using a double cathode glow discharge technique to improve the corrosion resistance and bioactivity of this biomedical alloy. The new coating has a thickness of ~40 μm and exhibits a compact and homogeneous structure composed of equiaxed β-Ta grains with an average grain size of ~22 nm, which is well adhered on the substra...

Luminescent bolometers are double-readout devices able to measure simultaneously the phonon and the light yields after a particle interaction in the detector. This operation allows in some cases to tag the type of the interacting quantum, crucial issue for background control in rare event experiments such as the search for neutrinoless double beta decay and for interactions of particle dark mat...

Application of a delaminated kaolin clay base coat onto linerboard provides a barrier coating for a subsequently applied polymer top coat with potential advantages of increased paper stiffness, improved water resistance at reduced polymer overcoat. Motivated by coating material cost reduction, feasibility of the technique is demonstrated by applying a delaminated clay coating online followed by...

This article describes a self-healing coating for corrosion protection of metals, which combines two different types of self-healing mechanisms in one coating with multiple-healing functionality. 2-Mercaptobenzothiazole (MBT) was loaded into layered double hydroxide (LDH) carriers that were mixed into an acrylated polycaprolactone polyurethane-based shape-recovery coating and applied on hot-dip...

There are no methods described for the preparation of vesicles with a double phospholipid bilayer, except for vesosomes as multicompartmental aggregates of tethered vesicles encapsulated within a large bilayer vesicle [1]. They are tethered to the aggregate by biotin-streptavidin coupling. The yield of this process is about 5%. The modified reverse phase evaporation method was used to prepare t...
