Thermodynamic evidence for the selective Ca(2+)-mediated self-aggregation via carbohydrate-carbohydrate interactions of gold glyconanoparticles functionalized with the disaccharides lactose (lacto-Au) and maltose (malto-Au), or the biologically relevant trisaccharide Lewis X (Le(X)-Au), was obtained by isothermal titration calorimetry. The aggregation process was also directly visualized by ato...

In the context of global energy transformation, it is particularly important to tap potential flexible load on distribution network side participate in grid operation. As an adjustable network, air conditioning loads have typical characteristics thermal storage, rapid response, and scheduling, which ideal resource. Effective reliable aggregation technologies for participation are basis operatio...

Methods Recombinant wild-type (WT) and variant MK proteins N-terminally fused to a maltose binding protein (MBP) were expressed in E. coli. Following affinity purification and size exclusion chromatography, the MBP-MK fusion (fMK) or cleaved MK (cMK) proteins, respectively, were characterized with regard to oligomerization, thermal unfolding monitored by differential scanning fluorimetry, therm...

Colloidal aggregation processes arising at different electrolyte concentrations were studied by means of experiments and confronted with theoretical predictions of different kinetic aggregation models. For this purpose, aqueous dispersions of relatively large polystyrene microspheres were chosen as experimental systems. Aggregation was induced by adding KBr electrolyte to the initially stable p...

A serial erythrocyte sedimentation procedure is based on maintaining blood in vitro in thermal (body temperature) and flow equilibrium, as changes in sedimentation rate are evaluated at 20-mm intervals. Each measurement was made 1 h after the determination was begun. We thus confirmed in vitro the clinically observed effects of quinine on blood cell aggregation. A delayed effect of quinine on a...

State of the art data centers use wired sensors embedded in equipment for thermal monitoring. The high cost of sensor installation restricts equipment relocation. We propose using a wireless self-locating network of smart sensing nodes, called SmartLOCUS, for automatic sensor configuration. We explore how to design the sensor control software to be self-reconfiguring when nodes relocate. The so...

We introduce a siloxane chain-based hydrophobizer that exhibits superior thermal and chemical stability compared to the conventional hydrophobizing silane agent under conditions of over 300 °C and pH 2-13. To demonstrate the capability of the siloxane chain-based hydrophobizer to serve as a highly robust chemical surface modifier, we present two applications: the formation of fine metal nanopar...

protein aggregation is a problem in biotechnology. high temperature is one of the most important reasons to enhance enzyme inactivation and aggregation in industrial systems. this work focuses on the effect of tio2 and sio2 nanoparticles on refolding and reactivation of lysozyme. in the presence of tio2 and sio2 nanoparticles, after enzyme heat treatment at 98◦c for 30 min, not only aggregates ...

objective: to study the mechanisms involved in amyloid formation processes, we made a mammalian cell culture model of amylin aggregation and characterized its properties. materials and methods: amyloid fibrils were extracted from cho cells and binding affinity to thioflavin t and congo red was investigated. then the apple-green birefringence of extracted fibrils was detected under polarized li...
