Introduction Silk fibroin protein, the self-assembling structural protein in natural silkworm fibers, has been increasingly studied because of its excellent mechanical properties, biocompatibility, controllable degradation rates, and inducible formation of crystalline β-sheet structure networks [1-6].
These conditions which could potentially alter cell function and affect cell viability.
In sonication, mechanical vibration causes the formation and collapse of bubbles.
It is likely that several physical factors related to sonication, including local temperature increases, mechanical/shear forces, and increased air-liquid interfaces affect the process of rapid gelation of silk fibroin.

Study on Perez [2] shows that the mechanical properties of TIPA on hydration of Portland cement paste did not improve, but improve the strength of mortar and concrete, mainly because it exsits an interfacial transition zone between sand, aggregate and cement paste.
The relationship between the initial structure and mechanical properties of TEA and cement was studied by Ma Baoguo et al. [19] .It was found that critical amount of TEA was 0.02% and 0.15% respectively.

Introduction To control mechanical properties of a material subjected to an annealing treatment after cold rolling, an adequate quantitative description of the softening behavior is crucial.
Also for the second variant (C1-B, Fig. 1b), which is moderately affected by pre-existing dispersoids (cf.
In terms of modelling, a somewhat better agreement is obtained with a combination of a much lower mobility pre-factor M0 and a tripled PZ value (dashed line).

This paper investigates the effect of different equal channel angular pressing (ECAP) routes and number of ECAP passes on resulting microstructure, mechanical properties and creep behaviour of selected materials.
However, a little apparent dependence of the creep properties was observed during subsequent pressing.
It is important to say that creep properties of UFG materials strongly depend on microstructure evolution.
The results show that successive ECAP pressing leads to a noticeable decrease in the creep properties.

Many studies have shown, PBL shear key both in the manufacture and mechanical properties have a great advantage than the traditional shear connectors [2].
Many factors affect the size of this force, such as concrete strength, steel yield strength, the bar diameter, steel hole diameter and so on.
Its main failure modes include two factors: Concrete tenon pressure damage and shear failure of the plate between holes.
Even the same factors are considered, experimental error will cause different amendments to the formula.

In order to avoid the damage of the mechanical or magnetic carbon seal static ring, its surface could be hard Chrome plated and anti-bubbling and anti-coking graphite with excellent heat conduction property could be used as well as the seal case of which the thermal expansion factor is near that of the graphite ring.

The possibility of anodic oxidation of SiC surfaces by a strong, local electric field applied during Atomic Force Microscopy (AFM) under ambient conditions is an interesting method to achieve nano-patterning of SiC, but is also a side-effect to be well characterized and controlled during this kind of AFM measurements if used to determine the local electric properties.
Based on Atomic Force Microscopy (AFM), several modes are becoming essential techniques to probe local electrical properties.
The force curves show that the adhesion force, between the AFM tip and the SiC surface, increases of a factor of 1.5 when a voltage of -10 V is applied to the tip.
The electric field is around 8.2 x 109 V/m at the contact point and it is divided by a factor 10 at 20 nm away from the contact point.
The topography in the area of the contact source is due to the different mechanical properties of the materials (SiC, oxide and metals).
