World Health Organization (WHO) has expressed great concern about the pandemic of Coronavirus (COVID-19) and said that there is a need to control it at the high end. To strengthen this fight against COVID-19, International Association of Advanced Materials (IAAM) intends to provide a forum for high-tech healthcare. Foreseeing the current crisis, IAAM called a multi-lateral consortium to discuss the possibilities of developing a medical technology to control the spreading of coronavirus with the help of interdisciplinary experts from multiple countries. This innovation is perpetuated to create multi-lateral cooperation in the area of ‘healthcare innovation and technology’. Adaptation of advanced technologies and their logical integration according to contemporary healthcare measures could be a smart strategy for epidemic management activities. Establishing an advanced phenotype model for prognosis is an important step in the prevention of infectious disease management such as COVID-19. This article has overviewed the global situation, efforts, and prospective of coronavirus pandemic.

With the aging of society, accidental falls among the elderly are increasing. The main factor is the deterioration of balance due to the decrease in physical ability. Another key factor with elderly people is that the position of the body's center of gravity tends to sway from side to side while walking. To find a way to cope with falls in the elderly, we have developed a new gait training system that handles the central gap of gravity position with soles. Here, a new element consisting of silicone rubber and foam rubber is used for the insole of the shoe. By using this element, it is possible to measure the foot pressure distribution and adjust the change in element stiffness. Further, the measured data of the insole can be displayed on the terminal device. Also, this data can be stored on the server. Moreover, by operating the terminal device, the insole element is pressurized and the stiffness of the element can be adjusted. Further, the developed system enables real-time measurement of changes in foot pressure distribution during walking. In this paper, we show that the difference in walking patterns can be clarified.

There are currently two opposing views on vitalized water. Some authors consider everything around vitalized water as a pseudo-science. On the contrary there are good and positive insight. In this article are the water properties described in detail. Water vortex and magnetic field of permanent magnets changes some of the water properties. It is different in vitalized water created by different water vitalizers. Next aim of the article is to describe 8 ways how we can obtain vitalized water, measure the physical properties of vitalized water (diamagnetism, wettability, surface tension and conductivity) and compare the efficiency of these 8 ways of changing behaviour of water. There are 8 types water vitalizers: 1) a connector with a hole for 2 PET bottles, 2) a connector with magnets added, 3) a magnetic vortex vitalizer for water tap, 4) a vitalizer for a bathtub in the bathroom, 5) vitalizer with a motor and magnetic stirrer, 6) vitalizer with balls, 7) vitalizer for watering gardens and removing settled minerals in heating pipes and regulating heads, 8) vitalizer with shungite. The article will explain what is the diamagnetism of water. The water's magnetic properties change most.

The sensor response experiments of piezoceramic shear same poled d15 patches which are integrated in a composite sandwich beam-like structure and connected in parallel and series configurations are presented in this letter. The core of the smart structure is formed from four piezoceramic shear d15 patches arranged in the same polarization (SP) direction and sandwiched between two identical glass fiber/epoxy layers. The dynamic response of the composite structure was monitored using these four piezoceramic shear d15 patches acting as sensors in parallel and series configurations and the data were evaluated by a pulse-multianalyzer system. A charge amplifier was used as a signal conditioning circuit between the piezoceramic shear d15 patches and the pulse-multianalyzer system. The outputs of the piezoceramic shear sensor were in a short-circuit state with the use of the charge amplifier. The results are promising as the proof of using piezoceramic shear same-poled d15 patches to sense the response of beam-like composite structures.

While the energy efficiency of railway transportation is quite high in comparison with that of the roadway transportation, there are still some aspects that preclude any greater efficiency for this transportation mode. Specifically, during the negotiation of turns, some locomotive energy is lost due to the rubbing of the wheels´ flange with the rail head, being the amount of such an energy a function of a multitude of parameters that are car- and track- related. In this paper, a carburizing treatment is proposed to reduce the friction between the rail and the wheel´s flange, involving the selective carburizing of the lateral surface of one of the rail head´s sides. The proposed furnace´s design is supposed to the installed next to the hot-rolling facility and includes the needed equipment to avoid decarbonization of the non-treated rail material

Current evolutions in medical practices induce a change of paradigm with the convergence of diagnosis and therapy, going to precision medicine and “theranostics”. One can observe the new role of biomarkers in biomedical and therapeutic applications, for instance in the development of molecular multiplex biosensors (nucleic acid, proteins, and metabolites). In addition, there is an increasing interest for point-of-care (POC) and of home monitoring/testing technologies devoted to probe patient parameters in his direct environment. The obvious constraints for such a kind of new clinical practices are simplification, drastic cost reduction while keeping high performances. Within this context, synthetic biology provides new opportunities to develop a novel generation of biological biosensors able to perform multiplexed biomarkers detection, simple computation and returning simplified relevant results. In order to design robust synthetic biological biosensor systems reliable in a clinical context and based on biochemical circuits, we developed an original methodology ensuring biochemical implementation of logical tasks within nonliving artificial cells. This methodology covers in silico design, simulation, microfluidics production and clinical validation on human samples. It ends up in very simple assay like for instance the new insulin-resistance assay, which is also quick and easy to run out of a laboratory and at low cost.

In order to introduce a new promising material for hydrogen storage application, Nickel (Ni) has been decorated on C12N12 nano-cluster. Firstly, the binding mode of Ni on C12N12 could be thought to be a bridge in between C, N (denoted as C-(μ-Ni)-N) or C, C (denoted as C-(μ-Ni)-C) or N, N (denoted as N-(μ-Ni)-N) resulting in three distinct geometries (abbreviated as XCN, XCC, and XNN isomers, respectively). Owing to the variation in the bridging mode of Ni, the interacting properties with the hydrogen molecule are expected to be different. The spontaneity of formation of Ni-C12N12 and 4Ni-C12N12 in terms of ΔHºf of isodesmic reactions indicate the possibility of getting promising high-energy-density materials (HEDMs). Further, we have investigated whether Ni, being a 3d transition metal, can influence the aromatic behavior of C12N12 nano-cluster. The binding energies and natural bond orbital (NBO) charges have been computed and energy decomposition analysis is carried out for Ni-C12N12 isomers. Decoration of Ni on XCN isomer releases slightly lower energy (~107.4 kcal/mol versus ~58.6 kcal/mol for XNN and XCN respectively). The hydrogen adsorption capacity of the strongest and the weakest Ni-bonded Ni-C12N12 nano-clusters (XNN and XCN isomers, respectively) has also been investigated.

Glass fiber (GF) and mica (MC) filled polycarbonate (PC) composites were fabricated using extrusion process due to considerable applications of PC as recyclable and thermo-stable material in mainly medical, packaging and transportation fields. Tensile, hardness and impact tests, differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA), melt flow index (MFI) test and scanning electron microscopy (SEM) findings were reported. Mechanical test results show that tensile strength and modulus are improved for higher GF and lower MC contents. The necking behavior of PC disappear after MC and GF inclusions due to the reduction of ductility. Impact strength of PC is reduced with both additions of GF and MC. Glass transition temperatures (Tg) of PC and relevant composites were estimated by the help of DSC analysis. Tg of PC hifts to higher temperatures by the addition of GF. According to TGA results, GF and MC additions cause remarkable increase in thermal stability of PC. MFI of PC extends up to higher values with increase in GF concentration. SEM analysis reveals that GF and MC display nonhomogeneous dispersion for their high loading ratios. Individual inclusions of additives yield higher mechanical and thermal performance than hybrid composites.

In this communication, we report the results of different light illumination on electrical transport properties of La0.67Ca0.33Mn0.9Ga0.1O3 (LCMGO) thin films grown on Si (100) ( n-type phosphorus-doped) wafer using Pulsed Laser Deposition (PLD) System. The variation in deposition time changes the thickness of the films. X-ray Diffraction (XRD) reveals the polycrystalline structure of LCMGO thin films. The cross-sectional SEM were taken to determine the thickness of the films with changing deposition time. Atomic Forced Micrographs (AFM) show that island type grains diffuse into one another to form a more uniform distribution of grains as the thickness of the film increases. The charge transport properties have been studied using the I-V measurement at LCMGO/Si interfaces. I-V measurement shows the backwards-diode like the behaviour of the LCMGO/Si p-n junction. The reverse bias current changes under the influence of different incident light illumination. The built-in electric field is generated at the interface when the film was illuminated with UV light. The tunnelling process for backward diode like p-n junction is explained using a modified Simmons model.
