The health care driven tools and solutions speed up the overall time for treatment as well as create better-enduring experiences, which is the need of the hour, at the same time. It eventually raises the standards of the health care industry across the spectrum by understanding as well as responding to customers in a systematic and logical manner. Computational and information system that mines healthcare database with improve treatment cost-effectively, seeking opportunities for growth in industry regularly. Challenges and opportunities were counterbalance by artificial intelligence (AI), information technology, 3-D printing etc. in astounding ways to encourage healthy lifestyles. Besides that, these modern tech tools and solutions have the ability to create a wide range of AI-enabled medical models, as well as develop and analyze critical data, and bear in mind, all-in-one integrated medicine for streamlined care. According to recent studies, the tech advancements not only provides key insights but also integrate modern channels too such as emails, social media and more patterns to foster better relationships. They are designed to reveal invaluable insights of digital medicine from the current trends in real time, which has the ability to empower the entire health care industry.

Spherical Nb-Si powder alloy is a perspective material to manufacture products for the aerospace industry by additive technologies. Nb-16Si (at.%) powder alloy was prepared by mechanical alloying from pure elemental powders using planetary ball mill Fritsch Pulverisette 4. Spheroidization was carried out on plasma generator based on thermal plasma arc generator with vortex discharge stabilization. Experimental results show that plasma spheroidizing of Nb-16Si powders obtained by mechanical alloying is possible. It is shown that after the spheroidization the particle surface is rough which indicates the cast structure of the material. Three phases having different optical contrast are revealed on microsections: Nb5Si3, Nb3Si and Nbss, which is confirmed by X-ray diffraction. It is shown that the main peaks in the X-ray graph after MA correspond to a solid solution of niobium with a cubic lattice and the parameter a = 0.333 nm, as well as niobium silicide Nb5Si3 with a hexagonal lattice (P63/m) a = 0.7536 nm and c = 0.5249 nm. After spheroidization the hexagonal lattice of niobium silicide Nb5Si3 is transformed into a tetragonal lattice (I4/m) with the parameter a = 0.6557 nm and c = 1.186 nm. The other phase components remain unchanged.

Using ultrasonic technology, phenylmethylsilicone/organic montmorillonite (OMMT) nanocomposites were prepared by in-situ intercalative polymerization. The internal structure and morphology of nanocomposites were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM) analyses. The basal spacing of OMMT increases with the increasing of ultrasonic time. Intercalated and exfoliated phenylmethylsilicone/OMMT nanocomposites were successfully prepared by convenient process of changing ultrasonic time for 15 min and 30 min, respectively. The barrier property for water was obviously improved by adding OMMT into silicone. The water absorption rate of intercalated nanocomposite containing 4wt% OMMT is 0.7687%, which is 10 times less than that of pure silicone. However, the water absorption rate of exfoliated nanocomposite is 2.802%, which is 3 times less than that of pure silicone. The nanocomposite containing 6wt% OMMT has the best mechanical performance. The impact strength of intercalated nanocomposite is 1.593 2 kJ/m 2 , which is enhanced 7.45% more than that of pure silicone, and the impact strength of exfoliated nanocomposite is improved 14.4% to 1.695 7 kJ/m 2 . The tensile strength of intercalated nanocomposite was markedly enhanced from 1.247 MPa of pure silicone to 7.021 MPa and to 6.264 MPa for exfoliated nanocomposite. When nanocomposite contains 4wt% OMMT, the compressive strength of pure silicone is also evidently improved from 2.834 MPa to 10.232 MPa of intercalated nanocomposite and to 11.503 MPa of exfoliated nanocomposite, respectively. The hardness of exfoliated and intercalated PLS nanocomposites are both firstly increased with the increasing of OMMT content, and then decreased, and finally increased again.
