For example, in at least one possibly preferred embodiment, a composite separator is provided with a fibrous mat for retaining the active material on an electrode of a lead-acid battery. In at least one possibly particularly preferred embodiment, a PE membrane separator is provided with at least one fibrous mat for retaining the active material on an electrode of a lead-acid battery. In accordance with at least certain embodiments, aspects and/or objects, the present invention, application, or disclosure may provide solutions, new products, improved products, new methods, and/or improved methods, and/or may address issues, needs, and/or problems of PAM shedding, NAM shedding, electrode distortion, active material shedding, active material loss, and/or physical separation, electrode effectiveness, battery performance, battery life, and/or cycle life, and/or may provide new battery separators, new battery technology, and/or new battery methods and/or systems that address the challenges arising from current lead acid batteries or battery systems, especially new battery separators, new battery technology, and/or new battery methods and/or systems adapted to prevent or impede the shedding of active material from the electrodes, preferably or particularly in enhanced flooded lead acid batteries, PSoC batteries, ISS batteries, ESS batteries, and/or the like.

Disclosed herein are carbon molecular sieves and methods of making the same through the pyrolysis of a polymer precursor in the presence of a reactive gas stream including a hydrogen source.

This invention integrates a membrane with a steam reformer such that a membrane is placed between a raw biogas feed, and a steam reformer to supply a retentate of purified methane feed to the steam reformer and the permeate as fuel to the steam reformer,

A gas-separation membrane obtainable from curing a composition comprising one or more curable monomers at least 30 wt % of which are monomer(s) comprising oxyethylene groups, oxypropylene groups and at least two polymerizable groups.

The present invention provides a separation membrane suitable for separating water from a liquid mixture containing an alcohol and water. The separation membrane of the present invention includes a metal organic framework. On the separation membrane, at least one of requirements (i) and (ii) below holds: (i) a ratio R1 of a number N2 of molecules satisfying a specified condition (b) with respect to a number N1 of molecules satisfying a specified condition (a) is less than 0.29; (ii) a ratio R2 of an adsorption amount of water adsorbed by the metal organic framework under water vapor at 25° C. and 3.2 kPa with respect to an adsorption amount of ethanol adsorbed by the metal organic framework under an ethanol atmosphere at 25° C. and 7.4 kPa is more than 4.0.

There is provided a thin film composite (TFC) hollow fibre membrane comprising a porous hollow fibre support layer formed of a polymer and a selective layer, formed of a cross-linked polyamide, on an inner circumferential surface of the hollow fibre support layer, wherein the TFC hollow fibre membrane has a power density of 25-50 W/m.sup.2 at a pressure of 30 bar. There is also provided a method of forming the TFC hollow fibre membrane.

A porous membrane includes a triblock copolymer of the formula ABC. B is a hydrogenated vinyl aromatic block present in a range from 30 to 90 weight percent, based on the total weight of the copolymer and has a T.sub.g of ≥110° C. C is a rubbery block present in a range from 10 to 70 weight percent, based on the total weight of the copolymer and has a T.sub.g≤25° C. A is substantially incompatible with both the B and C blocks and is derived from ring-opening polymerization. B+C is present in a range from 70 to 95 weight percent, based on the total weight of the copolymer.

The invention relates to a power distribution system (1), especially a Power-over-Ethernet system, comprising at least one dominant sensor, which may be located within a powered device (4) like a lighting device, and at least one non-dominant sensor, which may be located within another powered device (4), wherein the power distribution system is adapted such that in a system low power mode the at least one dominant sensor (6) consumes power provided by a power providing unit (3) and the at least one non-dominant sensor (6) does not consume the provided power and that the power distribution system (1) switches from the system low power mode to a system high power mode, if the at least one dominant sensor (6) has sensed an event. Since in the system low power mode the at least one non-dominant sensor does not consume power, the power consumption can be reduced.
