Abstract: The present invention relates to a polymer voltage-dependent resistor (PVDR) in various physical forms and methods for manufacturing the varistor. The body of the PVDR is composed of a polymer matrix having a filler composed of doped zinc oxide particles, other semi conductive particles or metal particles uniformly distributed therein. Conductive electrodes may be affixed to the polymer matrix and electrical leads attached to the electrodes.

Abstract: Various embodiments include a camera having a sensor-shifting mechanism. For example, the camera may include a voice coil motor (VCM) actuator to move an image sensor, relative to a lens group, to provide autofocus (AF) functionality. According to some embodiments, the VCM actuator may include one or more coils attached to a coil carrier, and one or more magnets attached to a stationary structure of the camera. The coil carrier may be attached to an image sensor package such that the image sensor is movable together with the coil carrier, in at least one direction parallel to an optical axis defined by the lens group. In some embodiments, the camera may include one or more suspension arrangements to suspend the coil carrier and/or the image sensor package from one or more stationary structures of the camera.

Abstract: Fluorescence titration of methylene blue, rhodamine B and rhodamine 6G (R6G) by silver nanoparticle (AgNP) all resulted in an initial steep quenching curve followed with a sharp turn and a much flatter quenching curve. At the turn, there are about 200,000 dye molecules per a single AgNP, signifying self-assembly of approximately 36 layers of dye molecules on the surface of the AgNP to form a micelle-like structure. These fluorescence-quenching curves fit to a mathematical model with an exponential term due to molecular self-assembly on a AgNP surface, or “self-assembly shielding effect”, and a Stern-Volmer term (nanoparticle surface enhanced quenching). Such a “super-quenching” by AgNP can only be attributed to “pre-concentration” of the dye molecules on the nanoparticle surface that yields the formation of micelle-like self-assembly, resulting in great fluorescence quenching.

Abstract: The invention relates to a polyamide compound and a use thereof. Specifically, the invention relates to a type of polyamide compound (which preferably comprise one or more amide bonds formed by condensation of same or different L-amino acids or D-amino acids), or stereoisomers, crystalline polymorphs, solvates, metabolites, prodrugs or pharmaceutically acceptable salts or esters thereof, or pharmaceutical compositions thereof, as well as a method for preparing the polyamide compound and a use thereof in the prevention or treatment of diseases associated with ?-opioid receptor. The polyamide compound of the invention has excellent ?-opioid receptor agonistic activity and hydrophilicity, thus having a lesser ability of penetrating the blood-brain barrier and a lower capacity for entering the brain.
