Abstract:
... Adhesive and cohesive fractures are the two possible modes of fracture during yield stress measurement of materials such as waxy oil gel. In this study, yield stress measurements were performed with a number of waxy crude and model oils using three geometries, including a smooth cylinder, a grooved cylinder, and a six-bladed vane. Experimental conditions were varied to obtain a wide range of gel s ...

Abstract:
... Self-regulation of the dynamic actuation of a chemical oscillating reaction-based gel was realized by altering the network structure of the gradient double network gel. We demonstrated that the propagation mode of the chemical wave was influenced by the network structure, and consequently determined the dynamic feature of the gel actuator. ...

Abstract:
... Polyethylene glycol‐modified canine uricase (PEG‐UHC) was prepared by modifying the ε‐amino group of lysine residues on the canine uricase (UHC) protein to near‐saturation with 5 kDa monomethoxyl‐polyethylene glycol succinimide (mPEG‐SPA‐5k). In order to accurately determine the PEGylation uniformity of PEG‐UHC, CZE, 3–8% gradient gel SDS‐PAGE, and imaging CIEF (iCIEF) analyses were compared. CZE ...

Abstract:
... Over the years, a number of methodological variations in polyacrylamide gel electrophoresis (PAGE) have been attempted for the separation of milk proteins. Caseins are similar in size and differ very little in net charge from each other. Also, in heated milk, κ-casein not only complexes with whey proteins but also undergoes self-polymerisation. These cause problems in the resolution of milk protei ...

Abstract:
... The aggregation of protein-stabilised emulsions leads to the formation of emulsion gels. These soft solids may be envisioned as droplet-filled matrices. Here however, it is assumed that protein-coated sub-micron droplets contribute to the network formation in a similar way to proteins. Emulsion gels are thus envisioned as composite networks made of proteins and droplets.Emulsion gels with a wide r ...

Abstract:
... Ion current rectification (ICR), diodelike behavior in surface-charged nanopores, shows promise in the design of delivery probes for manipulation of neural networks as it can solve diffusive leakages that might be critical in clinical and research applications. However, it has not been achieved because ICR has restrictions in nanosized dimension and low electrolyte concentration, and rectification ...

Albite (NaAlSi₃O₈) makes up the sodium corner of the feldspar ternary diagram (KAlSi₃O₈ - NaAlSi₃O₈ – CaAl₂Si₂O₈) and connects the alkali-feldspar and plagioclase binary joins. Synthesis of albite, however, has long been a problem, even at high temperatu ...
