    Abstract: An anion exchange membrane is composed of a copolymer of 1,1-diphenylethylene and one or more styrene monomers, such as 4-tert-butylstyrene. The copolymer includes a backbone substituted with a plurality of ionic groups coupled to phenyl groups on the backbone via hydrocarbyl tethers between about 1 and about 7 carbons in length. High-temperature conditions enabled by these copolymers enhance conductivity performance, making them particularly suitable for use in anion exchange membranes in fuel cells, electrolyzers employing hydrogen, ion separations, etc. The properties of the membranes can be tuned via the degree of functionalization of the phenyl groups and selection of the functional groups, such as quaternary ammonium groups. Several processes can be used to incorporate the desired ionic functional groups into the polymers, such as chloromethylation, radical bromination, Friedel-Crafts acylation and alkylation, sulfonation followed by amination, or combinations thereof.

    Abstract: Chewing gums and chewing gum bases which are cud-forming and chewable at mouth temperature contains a multi-block copolymer having at least two repeating sequences of at least two different polymeric blocks having at least three monomer units each. The multi-block copolymer optionally includes linking units and may be formulated to have non-covalent crosslinking between the copolymer chains. The multi-block copolymer is optionally plasticized with a compatible di-block copolymer to function as an elastomer system in the gum base. Characteristics of the multi-block copolymers can be selected to produce gum bases and chewing gums having desired properties. In some cases, chewed cuds formed from the gum bases may exhibit improved removability from environmental surfaces to which they may become undesirably attached.

    Abstract: A magnetic resonance imaging apparatus that carries out a pulse sequence for making a signal of a first substance within an object smaller than a signal of a second substance within the object. The pulse sequence includes an α°-pulse for exciting the object, a refocus pulse for refocusing a phase of spin within a region excited by the α°-pulse, and a readout gradient field for acquiring a magnetic resonance signal from the region. The α°-pulse has a spectral selectivity such that a transverse magnetization of the first substance is made smaller than a transverse magnetization of the second substance. The refocus pulse has a spectral selectivity such that a phase of spin of the second substance is refocused and refocusing of a phase of spin of the first substance is suppressed.

    Abstract: A secondary battery has a safety vent formed on a can accommodating an electrode assembly. The safety vent is formed in a groove shape and the depth of the groove varies. The fracture site of the safety vent is controlled by adjusting the depth of the safety vent. The safety vent is prevented from damaging the electrode assembly when the electrode assembly is inserted in the can, and contacts the safety vent.

    Abstract: A first roadside equipment operates as a transmitting/receiving mode in a control channel interval of an Nth synchronization interval so as to support a handover. In this instance, a second roadside equipment neighboring to the first roadside equipment operates as a receiving mode in the control channel interval of the Nth synchronization interval. The first roadside equipment operates as the receiving mode in a control channel interval of an (N+1)th synchronization interval. In this instance, the second roadside equipment operates as the transmitting/receiving mode in the control channel interval of the (N+1)th synchronization interval.
