Due to the increasing complexity of circuit boards, testing loaded boards is becoming prohibitively expensive and more difficult to perform. Board complexity has resulted from the rapid development of surface-mount technology and from the use of multilayered boards. Finer pin spacing and the use of double-sided boards also have contributed to the increased cost and difficulty of traditional tes...

Reinforced concrete (RC) structures require strengthening for numerous factors, such as increased load, modification of the structural systems, structural upgrade or errors in the design and construction stages. The side near-surface mounted (SNSM) strengthening technique with glass fiber-reinforced polymer (GFRP) bars is a relatively new emerging technique for enhancing the flexural capacities...

The fate of the circumferential bundle of microtubules in activated platelets has been a subject of disagreement. Thin sections of stimulated platelets fixed at multiple intervals following exposure to aggregating agents have revealed that the circumferential band is constricted into a tight ring around centrally concentrated organelles. However, studies of detergent-resistant platelet cytoskel...

A reliable microfluidic platform for the generation of stable and monodisperse multistage drug delivery systems is reported. A glass-capillary flow-focusing droplet generation device was used to encapsulate thermally hydrocarbonized porous silicon (PSi) microparticles into the aqueous cores of double emulsion drops, yielding the formation of a multistage PSi-lipid vesicle. This composite system...

Contrasts between beta relaxation in equilibrium viscous liquids and glasses are rationalized in terms of a double-well potential model with structure-dependent asymmetry, assuming structure is described by a single order parameter. The model is tested for tripropylene glycol where it accounts for the hysteresis of the dielectric beta loss peak frequency and magnitude during cooling and reheati...

We report a method for simultaneous ionic current measurements of single molecules across up to 16 solid state nanopore channels. Each device, costing less than $20, contains 16 glass nanopores made by laser assisted capillary pulling. We demonstrate simultaneous multichannel detection of double stranded DNA and trapping of DNA origami nanostructures to form hybrid nanopores.

Organic solar cells (OSCs) have increased their power conversion efficiency above 18% thanks to the use of non-fullerene acceptors in binary or ternary blends tandem configurations. In this article, a study on lifetime P3HT:O-IDTBR bulk heterojunction OSCs ITO-free flexible substrates is presented. A direct comparison glass–glass and plastic–plastic encapsulation performance, with special focus...

MgAl-Layered double hydroxide (LDH) films with different orientations on the two sides of a glass substrate, one of which was modified with poly(vinyl alcohol), have been obtained by a one-step in situ hydrothermal crystallization method, and the growth mechanisms of the two films are discussed.

Abstract Polyethylene Naphthalate (PEN) plastic scintillator has been identified as potential self-vetoing structural material in low-background physics experiments. Radio-pure scintillating components have produced from PEN using injection compression molding technology. These will be used optically active holders to mount the Germanium detectors Legend -200 neutrinoless double beta decay expe...
