An up to 80% encapsulation of GPS at pH 4.0 was achieved, with 1:2 drug to wall materials ratio and a 3% gelatin/gum arabic while stirring at 500 r/min.
Gelatin, a polyampholyte obtained by a controlled hydrolysis of insoluble collagen, is one of the most important wall materials in microcapsule production.
Materials and methods Preparation of GPMC.
The ratio of drug to wall materials, the content of wall material, pH value and stirring rate all at three levels were investigated in the orthogonal array design (Table 1).

FeSiAl powder core coated by Ba-B-P-O system insulating layer Ding Wei1, a, Wang X 1,b※, Feng Z K1,c and Gong R Z1,d 1School of Optical and Electronic Information, Huazhong University of Science & Technology, China aDing.Wei@smail.hust.edu.cn, bwangx@mail.hust.edu.cn, cfengzekun@mail.hust.edu.cn, drzhgong@mail.hust.edu.cn Keywords: soft magnetic composites, barium, permeability, DC property, core loss Abstract Sendust soft magnetic composites coated by a thin Ba-B-P-O system insulating layer were produced; SEM spectroscopy and Energy dispersive X-ray analysis spectroscopy confirmed that thin layers of Ba-B-P-O system covered the alloy powders.
These component materials offer several advantages over traditional laminated steel and soft magnetic ferrite cores in some application.
Insulating materials may be divided to organic and inorganic materials, phosphate system insulation has been concerned due to its high electrical resistivity, oxidation resistance and also it does not influence the consolidation behavior of soft magnetic powders [6, 7].

The basic structure of knit textile is shown in Fig. 2, on this basis, changes in interweaving techniques and materials can present the unexpected appearance of the fabric.
Fiber Beauty The rise of Fiber Art has evoked curiosity in and exploration to materials, and has also inspired the innovation of textile fabrics.
Based on original fabric, we can create various patterns by reconstructing fabric texture with using fiber’s feature such as goose pimple of virgin fabric, nub yarn of linen fabric and slub yarn, or adding other materials in sharp contrast with the original ones.
Fig.3 Materials of different thickness are interweaved together to bring about some visual effect that are never tiring.

Introduction A challenging combination of properties including insensitivity to external stimuli, good detonation performance and high thermal stability is rather difficult and which is the reason for slow modern evolution of energetic materials[1].
Recently, a widely used technology in pharmaceuticals, cocrystallization, is employed in energetic materials to alter the properties of explosive like sensitivity, oxygen balance, detonation performance, and so on[2, 3].
As to energetic materials, sensitivity is one of the most significant properties, which has a great influence on their production and application.
In recent years, molecular dynamics simulation has played an important role in investigating thermophysical, mechanical, cohesive energy, sensitivity, and phase transition of the energetic compounds and their composite materials.
Usually, ductile material has a positive value of Cauchy pressure, while the brittle material has a negative one.

In the thixoforming process, the initial material is produced by reheating a solid billet to semisolid region, thus the transfer and reheating of billet is comparably simple and canbe automatic realized[5].

Introduction Requirements for the characterization of concrete in terms of its mechanical properties and possible degradation often also relate to the materials of existing structures.
The authors of this contribution handled a similar characterization in e.g. [1], while generalizing backgrounds and the significance of the characterization of materials for fracture response can be found in e.g. [2].

Chitin and chitosan are promising materials for medical applications due to their bacteriostatic/bactericide properties, biocompatibility with human tissues, and ability to facilitate regenerative processes in wound healing [12].
Within this context, it is of major importance the development of biocomposites that enable reconstruction of bone tissue, meeting the growing demand for these materials in biological applications of diverse health areas.
