Kinetic Modeling of Isothermal or Non-isothermal Adsorption in a Pellet: Application to Adsorption Heat Pumps [PDF]
, 2010 Understanding the interaction between a fluid and a solid phase is of fundamental importance to the design of an adsorption process. Because the heat effects associated with adsorption are comparatively large, the assumption of isothermal behavior is a ...

Kinetics of Enzyme Adsorbed on Adsorbent
The Journal of the Society of Chemical Industry, Japan, 1969 酵素をその活性を保ったままで不溶化し,基質と反応させようとする考え方は,酵素の研究,利用という面から多くの利点を与えるものと考える。著者らはその方法の一つとして吸着剤に酵素を吸着させることによって,水に不溶なcomplexを調製しているが,本報では被吸着酵素の動態を考察するためにMichaelis定数および最大速度を測定した。すなわち,酵素としては市販の糖化型アミラーゼを使用し,これを活性炭または酸性白土に吸着させてcomplexを調製し,これを種々な濃度の基質と反応させたところ,Michaelis定数はいずれもnative酵素より増加し,最大速度は減少した。これにより,吸着剤表面の酵素はかなり構造上の変化を受けていることがわかった。また吸着剤の種類によって ...

Sustainable CO2 adsorbents prepared by coating chitosan onto mesoporous silicas for large-scale carbon capture technology [PDF]
, 2015 In this article, we report a new sustainable synthesis procedure for manufacturing chitosan/silica CO2 adsorbents. Chitosan is a naturally abundant material and contains amine functionality, which is essential for selective CO2 adsorptions.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
