Dressing Materials

The aim of this paper is to introduce novel dressing with Mikania Micrantha for quick blood clotting and wound healing. When epidermis of human skin is cut or scrapped, sometimes too much bleeding occurs. Excessive bleeding may cause death, if bleeding is not stopped immediately. To promote blood clotting & wound healing natural based bio materials are still insufficient in medical textile sector. To fill up this scarcity, woven fabric treated with Mikania micrantha leaf juice & leaf powder was examined. M. micrantha exhibits good blood clotting time in comparison with available dressing materials. Woven fabric (bandage) that contains M. micrantha can be used for cut wounds healing purpose. The experiments were carried out in environment friendly way which indicates the production & processing of these dressing materials can have enormous contribution to sustainable operations and products.

ABSTRACTA thermal microprobe has been designed and built for high resolution temperature sensing. The thermal sensor is a thin-film thermocouple junction at the tip of an Atomic Force Microprobe (AFM) silicon probe needle. Only wafer-stage processing steps are used for the fabrication. The thermal response over the range 25–s 4.5–rovolts per degree C and is linear.

<a></a><a>As a metal-free conjugated polymer, carbon nitride (CN) has attracted tremendous attention as heterogeneous (photo)catalysts. </a><a></a><a>By following prototype of enzymes, making all catalytic sites of accessible via homogeneous reactions is a promising approach toward maximizing CN activity, but hindered due to </a><a></a><a>the poor insolubility of CN</a>. Herein, we report the dissolution of CN in environment-friendly methane sulfonic acid and the homogeneous photocatalysis driven by CN for the first time with the activity boosted up to 10-times, comparing to the heterogeneous counterparts. Moreover, facile recycling and reusability, the <a>hallmark</a> of heterogeneous catalysts, were kept for the homogeneous CN photocatalyst via reversible precipitation using poor solvents. It opens new vista of CN in homogeneous catalysis and offers a successful example of polymeric catalysts in bridging gaps of homo/heterogeneous catalysis.

Further Development

The events that took place in the first half of 2020 once again demonstrated how countries in the modern globalizing world are interdependent and interconnected: what is happening in one part of the planet inevitably affects other states, regardless of their geographical position. The Kingdom of Saudi Arabia is no exception. The crisis that arose because of the outbreak of the coronavirus infection hit the country’s infant economic system, disrupting the government’s ambitious plans to modernize and transform the kingdom. In this connection, it is of great scientific interest to study changes in the internal political course of the monarchy of the Persian Gulf, consider and analyze feasible scenarios for the further development of the country.
