Abstract:
A catalyst system and a method for manufacturing cyclic carbonate by the same are provided. The catalyst system includes a transition metal salt containing a halo group, an acetate group, or a combination thereof, and an organic phosphine ligand. The molar ratio of the organic phosphine ligand to the transition metal salt is greater than 0 and less than or equal to 50.
Abstract:
The present disclosure provides a fire-resistant composite material comprising: at least one inorganic component and at least one nonisocyanate polyurethane having a formula of: wherein R and R′ are each independently chosen from hydrocarbylene groups and hydrocarbylene groups having at least one heteroatom chosen from oxygen, nitrogen, and sulfur; and n is an integer chosen from 1 to 30. Also provided are processes for preparing the disclosed fire-resistant composite material.

Abstract:
A multi-input multi-output adder and an operating method thereof are proposed. The multi-input multi-output adder includes an adder circuitry configured to perform an operation. The operation includes the following. A first source operand and a second source operand are added to generate a first summed operand. Direct truncation is performed on at least one last bit of the first summed operand to generate a first truncated-summed operand. Right shift is performed on the first truncated-summed operand to generate a first shifted-summed operand. A bit number of the right shift of the first truncated-summed operand is equal to a bit number of the direct truncation of the first summed operand.
