Pt was deposited onto tungsten carbide powders using atomic layer deposition to produce core-shell catalysts for the hydrogen evolution reaction (HER). The Pt loading on these catalysts was reduced nearly ten-fold compared to a bulk Pt catalyst while equivalent HER activities were observed.
Chemiresistive vapor sensors combining functionalized gold nanoparticles and single-stranded DNA oligomers are investigated to enhance specificity in chemical sensing. Sensors are made by depositing DNA-functionalized gold nanoparticles onto microfabricated electrodes using four distinct sequences. Sensor performance is evaluated for response to relative(More)
Cold storage systems are great energy users in many countries, so the recycling of condensing heat is greatly concerned by people. Take large cold storage refrigeration systems for the research background, based on the heat pump heat recycling technology, the cold storage heat recovery system had been designed. Combined with heat pump drying technology, the(More)
To reduce energy consumption and carbon emission, this paper designs energy recovery technology of aquatic products processing plant, including refrigeration heat recovery and ice-making cooling recovery. Three heat recovery plans are compared and analyzed, while two ways about cooling recovery of ice-melting pool are compared. The results of analysis show(More)
Chemiresistive vapor sensors combining sensing capabilities of functionalized gold nanoparticles and DNA have been investigated. The sensors are made by depositing DNA-functionalized gold nanoparticles onto microfabricated electrodes and subsequent drying to obtain a nanocomposite film. Comparisons are made between DNA-AuNP sensors and alkanethiol-AuNP(More)
