Europium-Labeled Activity-Based Probe through Click Chemistry: Absolute Serine Protease Quantification Using (153) Eu Isotope Dilution ICP/MS

Click and analyze: The titled probe was synthesized by conjugating a sulfonyl fluoride and azido unit using click chemistry to give SF-Eu, which can react specifically with serine (Ser) in the active site of serine protease (SP). Combination of the method with (153) Eu-isotope dilution ICP/MS enables absolute protein quantification of active SPs in biological samples using only one (153) Eu(NO(3) )(3) isotopic standard.

The interactive platform provides bilingual contents that meets the requirement of domestic and international students and highly arouse the study interest and stimulate the initiative of students, as a result to improve their comprehensive quality and innovative ability.     

Electrochemical properties of conductive filler/carbon aerogel composites as electrodes of supercapacitors

Carbon black, multi-walls carbon nanotube (CNT) and vapor grown carbon nano-fiber with different contents were added to the carbon aerogels (CAs) electrodes as conductive fillers to improve their capacitive properties. The results show that maximum capacitance exists when the content of the conductive filler gets to its percolation threshold. CNT is the most ideal conductive filler. The CA with 1 wt% content of CNT has the best electrochemical performance; its specific capacitances are 141.3 F g^?1 at 5 mV s^?1 and 127.1 F g^?1 at 100 mV s^?1, 1.4 times and 2.2 times as high as that of CA electrode, respectively.
