When mole fraction of 4HB is less than 15%, the number of branch chains is relatively less, along with the increase of 4HB’s mole fraction, the distance between molecules increases, which leads to the decrease of intermolecular forces.
So edges and corners tend to grow thinning in front of the other crystalline grains, which increases dendritic growth trend and finally forms dendritic crystal.

Technology and Experimental Research Plan “Liquid wood” grains can be processed by mold injection, extrusion, calendering, blow molding, deep drawing or pressing into molded parts, half-finished product, sheets, film solder profiles, [2, 4].
After the orthogonality and the number of degrees of freedom conditions have been checked, there were 16 experimental tests to be conducted.

Fig. 2 shows the AFM photo of the fabricated VOx thin film, in which it can be found that the diameter of crystal grain is in the range of nanometer.
Through a large number of experiments, a list of optimized process parameters to fabricate VOx thin film with nanostructure in our laboratory are gained and summarized in table 1.

Among the materials termed as martensites include a large number of alloys with the common feature of undergoing martensitic transition (MT).
Phenomenological Modeling The model is based on a strain formalism within a coarse-grained Ginzburg-Landau framework.

The effect of silicon contained in iron alloy substrates subjected to the process of zinc-coating in the conditions of metallization (440-460°C) has been explained a number of times [1-7].
Low solubility of silicon in phase z leads to its segregation at the border of grains and formation of areas of liquid Zn between z crystals [6].

Introduction Zn-Al-Cu type alloys are characterized by a number of advantageous properties which include: good castability, good tribological properties, low energy for shaping the product.
The main alloying element is aluminum [3], its addition increases the castability, influences the size reduction of grains and improves the mechanical properties [5].

The cellular composites used in the present study are manufactured from glass foam granules with the grain-size fraction of 12 mm supplied by Dennert Poraver GmbH, Germany.
Specimens tested at 1 Hz and at 20 Hz test frequency fail after approximately the same number of cycles.

In this equation, S is Cu0 surface area,is chemisorption stoichiometry at monolayer coverage, m is the mass of catalyst, NA is Avogadro constant, V is the total volume of N2O decomposed, Vm is the molar volume, and N is the number of copper metal atoms per unit area of surface (1.47×1019 m-2).
Catalytic activity The dehydrogenation of SBA towards MEK was carried out at atmospheric pressure in a downflow fixed-bed reactor. 1g of the catalyst was charged into the reactor and supported on a quartz grains bed.
