BACKGROUND Desflurane is known to produce high concentrations of carbon monoxide (CO) in desiccated sodalime or Baralyme (Allied Healthcare Products, St. Louis, MO). Desiccated absorbents without strong bases like potassium hydroxide or sodium hydroxide are reported to produce less or no CO at all. The purpose of this study is to compare the concentration of CO in an anesthesia circuit for desf...

We demonstrate Ni–N/C is an effective electrocatalyst for the direct conversion of captured CO 2 in monoethanol amine-based aqueous absorbents showing high faradaic efficiency (78%) and its selectivity maintained various amine solvents.

introduction ensiling is one of the common preserving methods for forage or other organic materials. in this method, organic matters were preserved by proving an aerobic condition and then by reducing the ph with increasing acids production (mainly lactic acid). some circumstances like enough soluble carbohydrates, low buffering capacity and appropriate dry matter concentration are needed in en...

introduction water super absorbents are water absorbing natural or synthetic polymers (they may contain over 99% water). they have been defined as polymeric materials which exhibit the ability of swelling in water and retaining a significant fraction (> 20%) of water within their structure, without dissolving in water content. the applications of hydrogels are grown extensively. these materials...
