Patients with limb motor dysfunction caused by trauma and stroke have poor mobility to take care of themselves, which seriously affects the quality of life of them. Through reasonable rehabilitation training, the damaged motor function can be relieved to a certain extent. In the rehabilitation training, the monitoring of limb movement can reflect the recovery state of patients’ physiological function and make a systematic evaluation on the rehabilitation training effect of patients,

The manufacture of scaffolds for wound healing has become important, especially the formation of tissuespecific scaffolding. In order to create scaffolds, it is essential to mimic the chemical composition, physical morphology and biological functions of the human body. Scaffolds can be created by using synthetic polymers (e.g. polycaprolactone) or natural polymers (e.g. chitosan) or a combination of both. The addition of natural polymers can be very advantageous as they can avoid

Green Nanotechnology: The Influence of Intermolecular and Supramolecular Interactions
In the last decade, the study of nanometer-scale particles has grown exponentially worldwide. This growth is due to the broad field of nanostructures applications, which, due to their dimensions in nanometric sizes, have new properties not found in micro and macro scale. These properties result from the increase in the ratio between the surface area and volume, and the nanostructures’ size directly influences these. Tolerance to temperature, variety of colors, changes in chemical reactivity,
Rapid Inactivation of SARS-CoV-2 by Coupling Tungsten Trioxide (WO3) Photocatalyst with Copper Nanoclusters
At the end of 2019, a novel severe respiratory disease (coronavirus disease 2019, COVID-19) spread to Wuhan, China, it became pandemic in few months, with more than 41 million people infected worldwide as of October 2020. COVID-19 is caused by a novel virus called severe acute respiratory syndrome (SARS) CoV-2 to distinguish it from SARS-CoV that emerged in Guangdong province in China in 2003 and caused the severe clinical condition known as SARS. Like SARS-CoV, SARS- CoV-2 causes a severe inter
Quantifying Respiratory Airborne Particle Dispersion Control Through Improvised Reusable Masks: The Physics of Non-Pharmaceutical Interventions for Reducing SARS-CoV-2 (COVID-19) Airborne Transmission
In light of the current pandemic from rapid transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 or COVID-19) and significant morbidity, there has been inconsistent medical guidance given to the public regarding the wearing of non-medical improvised fabric masks or face coverings to reduce the transmission of COVID-19.
