A significant drawback to ammonia borane as a hydrogen storage material is the production of ammonia gas during hydrolysis.As a possible solution, maleic acid is shown to be capable of fully promoting hydrolysis of ammonia borane while also preventing ammonia release in excess of single digit parts per million.The reaction is shown to be relatively
Some adolescents who live in orphanages may feel a lack of affection from their parents during their development; So, some orphanage adolescents experience a lack of guidance in dealing with problems in life, including mental health problems.To prevent this, it is necessary to have an attitude of self-compassion and self-disclosure of adolescents t

This paper introduces the construction composition and transmission principle of the screw pair steel ball planetary transmission mechanism with a coaxal Construction Vehicles input and output axes,calculates their transmission ratio function,gives the geometrical conditions of loading steel balls even distributed in space,presents the construction
One of the promising ways of removing large heat fluxes from the surface of heat-stressed elements of electronic devices is the use of evaporating thin layer of liquid film, moving under the action of the gas flow in Bulbs a flat channel.In this work, a prototype of evaporative cooling system for high heat flux removal with forced circulation of li
