“…After the completion of pyrolysis, the sample is removed from the reactor and cooled at room temperature. The gases present inside the GS glasses tubes are displaced by adding water, and residual char or coke is collected and weighted [53].…”

Renewable energy and alternative fuel from different conventional resources such as biomass, plastic waste, and recyclable polymers are impertinent environmental issues worldwide. Furthermore, to replace fossil fuel and reduce greenhouse gas emissions that have a negative impact on climate change. This article exhibits the effect of metal oxide composite/clay in the thermal decomposition of Polypropylene. That hetrocatalyst composed nano-clay thin layer loaded with MnO2 -NPs works on cracking of polypropylene under different reaction conditions like heating temperature, rate of reaction, reaction time, and composite loading ratio. Various techniques such as GC and TEM were used to characterize pyrolysis gases and char, in addition to scanning electron microscopy (SEM), Fourier transform infrared (FTIR), Thermo-gravimetric analyzer (TGA), and X-ray diffraction (XRD) were used for composite characterize. High gas yield and char rate conversion were obtained using synthesize composite.

“…89,90 However, with fear of cross contamination in the setting of the HIV pandemic, reuse of endotracheal tubes became an unacceptable practice, leading to the recommendation for single use endotracheal tubes with viral filters. [91][92][93] The role of the critical care physician was further relied on with the HIV pandemic. In the early years, patients would regularly require mechanical ventilation for Pneumocystis carinii pneumonia, which often proved difficult.…”

The infectious pandemics and epidemics of the past 200 years have caused millions of deaths. However, these devastating events have also led to creative thinking, imaginative experimentation and the evolution of medical care. As a result, the history of critical care medicine is entwined with the story of these global disasters. This article will take case studies from recent pandemics and epidemics and examine their impact on the development of anaesthesia and intensive care medicine.

“…Endotracheal tubes comprising polyvinyl chloride (PVC), for instance, are commonly used in medical emergencies to secure a patient's supply with air. [ 1 ] Catheters made from polyurethane (PU) have become an integral tool for drainage purposes and to support surgical procedures in cardiovascular, urological, or neurovascular medicine. [ 2,3 ] Polydimethylsiloxane (PDMS) is the material of choice for implantable tubes or devices.…”

Recent advances in the field of biomedical materials have demonstrated that covalent mucin coatings generated on polymeric materials have the potential to greatly improve the surface properties of medical devices such as their wettability, lubricity, and resistance toward biofouling. For such biopolymer‐based coatings to be used in a medical application, sterilization of the coated devices is mandatory. However, common sterilization methods such as autoclavation, ethylene oxide fumigation, as well as γ‐ or ultraviolet‐irradiation, create harsh conditions during the device treatment, and this might compromise the structural integrity and thus functionality of macromolecular coatings. Here, it is demonstrated that covalent mucin coatings generated on medical devices made from polyvinyl chloride, polyurethane, or polydimethylsiloxane are able to withstand such treatments—albeit to different extents. Among all treatments tested, ethylene oxide fumigation is identified as the most promising method as it maintains the coatings the best. The findings imply that the beneficial properties demonstrated for mucin coatings in vitro should indeed be transferable to applications in vivo.
