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
The problem of chip breaking and evacuation is the key point of staggered teeth boring and trepanning association (BTA) drilling.The factors that influence chip breaking with staggered teeth BTA deep hole drilling are analyzed NFL Boxes by using the chip bending deformation mechanism for chip formation and flow through the rake face and chip breake
