An ultrasound field was applied to obtain Polylactic acid (PLA)/Hydroxyapatite (HAp) biocomposite microspheres with the specific core-shell structure to be applied as a carrier of a drug.
The aim of this work was to further develop the PLA/HAp biocomposite microsphere with the specific core-shell structure to be applied as a drug carrier.

This device could be used in food, medicine, chemistry and so on.
The sketch of device structure is shown in Fig.1.
The influence of geometric structure limit orientation for the material particles Because the elastomer surface of particles are impacted on the normal component of elliptic motion.
Therefore, in order to realize the orientation of material conveying, we should consider using geometric structure limit orientation way to assist.
Conclusions In this paper, the structure and composition of multi-source piezoelectric vibratory feeder is introduced in detail.

Particles of chemical composition, crystalline structure, morphology and size similar to those of bone mineral were obtained by varying the composition of the components of the system.
Introduction Bone is a composite structure formed from a calcium phosphate mineral phase and from a collagen organic phase.
Comparing this material to the synthetic ones, it is possible to relate it to the CP-2 sample, which presents a film structure and Ca/P ratio near that of the PD and FD samples.
This morphology can be compared to that of sample CP-3, which presents ellipsoidal particles whose dimension and crystalline structure are similar to the ones found in the PM and FM samples.

The decolorization of methylene blue solution as model reaction, the effect of calcining temperature on the structure and photocatalytic performance of the samples were investigated.
Ultrasonic chemistry as a newly emerging interdiscipline has caused the attention of scientific workers.
These results indicate that ZnO has a hexagonal wurtzite structure.
Calcining temperature has significant influences on the size and structure of ZnO nanoparticle.
When the calcining temperature of precursor was fixed at 300 °C, the structure, morphology and photocatalytic activity of the ZnO nanoparticle were optimum.

The structure, phase composition, porosity, specific surface area and morphology of the obtained biosorbents are determined.
Eggshells are an abundant, cheap, biodegradable material with porous structure, slightly soluble in water (0.013 g/L at 18 ºC [4]).
A porous structure allows the exchange of matter between the outside and the inside of material [2].
(a) that the raw eggshells indicate well-defined narrow pore structures.

It was pointed out that the physical structure of simple cured epoxy resins did not essentially differ from that of common amorphous polymers.
A significant increase of Tg at higher chitosan loading confirmed that excessive chitosan content clearly alters the chemical structure of the sample.

A solvent-free high molecular mass PEO containing LiI and I2 produced dramatic morphological changes to the polymer structure upon addition of inorganic filler (TiO2 Degussa P25) and DSSCs fabricated by using this composite polymer electrolyte (CPE) gave overall conversion efficiency of 0.96% [8].
In this present study, the low molecular weight poly(ethylene glycol) (PEG) and (PEG-MA)-Ru, the structure of which is shown in Fig. 1, are added to the PEO/TiO2/KI/I2 CPE.

Since then many photonics and optical sensors have been combined that combines interdisciplinary research in chemistry, biology, physics, electronics, and optical Since then, it has been achieved a large number of optical sensors that combine interdisciplinary research in electro optics, photonics, physics, materials, chemistry, and biology.
Some of the interferometric fiber-optic sensors have been successfully commercialized and commonly used for composite material health monitoring, large civil engineering systems (e.g. bridges and dams), rockets, and aircraft, etc., leading to the creation of so-called intelligent materials and structures [2].
The main classes can be divided into several subclasses according to the fiber structure and the optical characteristics [21, 22]
Developments in materials, chemistry, biology, physics, and electronics have been essential for the progress in photonic sensor technology References [1] Ana M.
