From Fig.2(a), it can be clearly be observed that the powders obtained at 200oC with 6M NaOH consist of homogeneous and nearly spherical grains with the particle sizes about 200-300nm.
Therefore, the nuclear barrier was increased greatly, and the number of crystal nucleus was decreased obviously.

A hollow on the alumina ceramic surface was a grain boundary with a rich glass compound, which probably occurred due to etching with a body fluid during the clinical use.
A large number of scratches formed during clinical use were observed only on the retrieved Co-Cr alloy femoral components.

A large number of waste polyacrylonitrile fibers were produced in the production process every year.
Finally, the resulting product was treated with grain alcohol and dried at 85℃ in a vacuum drying chamber.

Introduction: Semi-solid metal alloys have a special microstructure of globular grains suspended in a liquid metal matrix that brings about significant numbers of benefits.

The chemimechanical polish used in the study was colloidal silica (CS) slurry with average grain size 60 nm and a pH of 11.

• Capacitor Dielectrics and Reliability, including: reliability of thin layers; dielectric breakdown relationships; electrode-dielectric interfaces; fine particle/fine grain properties; nonlinear dielectric properties; high-energy storage dielectrics
Visiting Scientists at CDS A number of member companies invest in the continuing education of their researchers by sending them to work at Penn State or UMR, alongside CDS personnel.

In the past few yeas, a number of studies have been conducted to evaluate the feasibility of friction stir welding of magnesium alloys.
However, overlarge heat input would result in grains coarsening, which cause that the strength of joint decline.

The number of female and male was identical.
of fine grains.

On the other hand the number of particles striking the cathode is proportional to the current density.
It is well known that the polycrystalline film generally has higher hardness than the amorphous film because of grain size hardening effect.

Ab initio calculation Ab initio calculations (i.e. first principles calculations) require as input only the positions and atomic numbers of each atom.
Figure 2 Examples of ab initio calculations; a vacancy [2], grain boundary [6], alloy [7], adsorption [8], interface [9], fullerene [11], and superconductor [12].
