Abstract: A method of forming an electrode having an electrochemical catalyst layer is disclosed. The method includes etching a surface of a substrate, followed by immersing the substrate in a solution containing surfactants to form a conditioner layer on the surface of the substrate, and immersing the substrate in a solution containing polymer-capped noble metal nanoclusters dispersed therein to form a polymer-protected electrochemical catalyst layer on the conditioner layer.

Abstract: A method of forming an electrode including an electrochemical catalyst layer is disclosed, which comprises forming a graphitized porous conductive fabric layer, optionally conditioning the graphitized porous conductive fabric layer, and dipping the graphitized porous conductive fabric layer into a solution containing a plurality of polymer-capped noble metal nanoclusters dispersed therein. The polymer-capped noble metal nanoclusters as an electrochemical catalyst layer are adsorbed onto the graphitized porous conductive fabric layer. An electrochemical device with the electrode made thereby is also contemplated.

Abstract: Histone deacetylase is a metallo-enzyme with zinc at the active site. Compounds having a zinc-binding moiety, for example, an alpha-ketoepoxide group, such as an alpha-ketothio group, can inhibit histone deacetylase. Histone deacetylase inhibition can repress gene expression, including expression of genes related to tumor suppression. Accordingly, inhibition of histone deacetylase can provide an alternate route for treating cancer, hematological disorders, e.g., hemoglobinopathies, autosomal dominant disorders, e.g. spinal muscular atrophy and Huntington's disease, genetic related metabolic disorders, e.g., cystic fibrosis and adrenoleukodystrophy, or to stimulate hematopoietic cells ex vivo.

Abstract: A cascade CO2 refrigeration system includes a medium temperature loop for circulating a medium refrigerant and a low temperature loop for circulating a CO2 refrigerant. The medium temperature loop includes a heat exchanger having a first side and a second side. The first side evaporates the medium temperature refrigerant. The low temperature loop includes a discharge header for circulating the CO2 refrigerant through the second side of the heat exchanger to condense the CO2 refrigerant, a liquid-vapor separator collects liquid CO2 refrigerant and directs vapor CO2 refrigerant to the second side of the heat exchanger. A liquid CO2 supply header receives liquid CO2 refrigerant from the liquid-vapor separator. Medium temperature loads receive liquid CO2 refrigerant from the liquid supply header for use as a liquid coolant at a medium temperature. An expansion device expands liquid CO2 refrigerant from the liquid supply header into a low temperature liquid-vapor mixture for use by the low temperature loads.

Abstract: A refrigerator has a fresh food compartment (3) adapted for maintaining the contents at a temperature above freezing. A vapour compression refrigeration system is operable in one mode so that an evaporator (7) is operated at a temperature within 10° C. of the temperature desired in the fresh food compartment (3) and a supply of air is maintained over the evaporator (7) and in to the compartment (3). The vapour compression system is used in a defrost mode in which the vapour compression refrigeration system is stopped or allowed to operate without significant heat extraction at the evaporator (7), and a supply of air above 0° C. is past over it. Operating the fresh food compartment evaporator (7) at such a high temperature (close to 0° C.) reduces the rate of frost build up and the under cooling of frost. Frost may be adequately removed by an ambient air flow without heater supplementation.
