Abstract: A separator for a battery formed from a polymer gel electrolyte that is disposed within the pores of a polymer mesh. The polymer gel electrolyte is formed from a crosslinked ion-conducting polymer and an ionic liquid. The separator is formed from a gel loaded with an electrolyte, which prevents issue with electrolyte leakage. The polymer mesh provides stability to the polymer gel electrolyte, allowing for use of thin films of the polymer gel electrolyte and use of soft polymer gel electrolytes.

Abstract: A light-emitting marker having a light-emitting core comprising a light-emitting material bound to a first biotin group and a biomolecule bound to a second biotin group. A protein, e.g. streptavidin or neutravidin, is bound to the first and second biotin groups. The light-emitting marker may be a light-emitting marker particle having a particulate core.

Abstract: A heat exchanger including a shell having a longitudinal axis, a plurality of baffles, such as elliptical sector-shaped baffles, each mounted in the shell at a helix angle HB to guide a fluid flow into a helical pattern through the shell. Each of the plurality of baffles includes an outer circumferential edge, a proximal radial edge, a distal radial edge, a proximal side, a distal side, and a plurality of spaced apart holes that are traversed by a plurality of axially extending tubes. Each of the first plurality of seal strips is disposed from a proximal of the plurality of baffles to a distal of the plurality of baffles.

Abstract: A light-emitting marker particle having a light-emitting particle core containing a light-emitting material and first and second surface groups bound to the light-emitting particle core. The first surface group contains a polar group and is an inert group which does not bind to a biomolecule. The second surface group contains a biomolecule binding group.

Abstract: A freestanding composite electrode film is made of an n-type or p-type electrochemically active polymer an electrolyte and/or a conductive carbon material. The freestanding composite electrode film may be used to form an anode or cathode layer of a polymer battery. The polymer battery may be formed from a stack/plurality of anode or cathode layers, each layer being formed from a freestanding composite electrode film.
