New Forensic Protocol in the Era of SARS-CoV-2

During the Sars-CoV-2 pandemic in Italy, even though many people died due to virus-induced complications, there was a warm advice from the government against performing body autopsies, instigating their incineration. It was a reckless decision, leaving clinicians and scientists empty handed when it comes to studying infection-induced tissue changes and subsequent organ failures, making it more difficulties in finding a better clinical solution for combating the virus.

Close Packing of Elements of Transparent Metamaterials in UVC Diapason and its Influence on The Decontamination Efficiency

A new method for repacking optical metamaterials formed from fiber or spherical elements of various diameters is proposed for ultraviolet C (UVC) decontamination of infected liquids that flow between these elements. It is proposed the method of repacking of metamaterial formed from closed packing big fibers/spheres with other subsystems of thin fibers/ bubbles replaced in the free space between the first packing fibers/spheres.

Evaluating the Economic Performance of Reverse Polymerization Technology for Waste Tyre Recycling in Sub-Saharan Africa

The unlawful and uncontrolled disposal of waste tyres is greatly disturbing in terms of the environmental concerns and the economic misfortune. In combating this menace, there is growing interest in the application of efficient and environmental-friendly alternatives to the traditional recycling methods for waste tyres. Pyrolysis can be considered as an appropriate non-conventional method for complex materials such as tyres. Several works have been made to improve pyrolysis process towards higher yield and quality of biofuels and greater energy efficiency. This study considers Reverse Polymerization, a microwave-assisted pyrolysis process to extract complete yield and higher quality of valuable products, while avoiding toxic emissions into the environment. The feasibility of such innovative recycling process in Sub-Sahara Africa is essential in order to convince concerned authorities to buy into such advanced technologies with great benefits. The investment analysis and economic performance indicators from the study demonstrated that the operation of such proposed recycling system in the continent is economically feasible. However, the operation of such facility under the present market conditions might highly be challenged by high investment risk as the project is highly capital intensive.

The Role of Nanotechnology in Semiconductor Industry: Review Article

Nanotechnology is now the key area of technology to create and manipulate materials at the nanometre (nm or 10-9 m) scale either by bottom up from single groups of atoms to bulk matter or by top down which is reducing bulk materials to a group of atom. Now a days it is being used or considered for use for fabricating and constructing many efficient electronic devices which have extremely large surface area to volume ratio, this makes a large number of surface or interfacial atoms, resulting in more surface dependent material properties specially this technology is used in semiconductor industry or solar cell industry.

The Effectiveness of an Activity Meter for Overweight Children and Their Caregivers in a Clinical Setting: a Pilot Study

Childhood obesity is epidemic in the United States, but low levels of physical activity and high levels of screen time are modifiable risk factors. An activity meter (AM) program, that utilizes an interactive child-focused website and measures the amount and intensity of physical activity, may promote activity and decrease BMI.The current study tests the feasibility of using an AM program with child-caregiver pairs in a primary care setting. We hypothesize that participants would rate the system as easy to use, would be motivated with their engagement in physical activity, and would continue to use and recommend to others. We hypothesize the AM system would increase children’s physical activity levels and decrease engagement in screen time over the study period. We also measure changes in participants’ body mass index (BMI).Prospective study assessing ease of use and satisfaction with the AM program post-intervention and comparing physical activity and BMI changes in children and caregivers from pre- and post-intervention over a 4-month period.

Complete Green Synthesis of Gold Nanoparticles using Laser Ablation in Deionized Water Containing Chitosan and Starch

In this paper we report our results on the green synthesis of nontoxic, stable, and small size gold nanoparticle suspensions. We used the single and two-beam laser to ablate a gold target submerged in deionized water containing chitosan or starch as the stabilizing agent. Since both chitosan and starch are biodegradable and biocompatible, use of these natural polymers for gold nanoparticle protection and stabilization does not introduce any environmental toxicity or biological hazards.

Ordered Growth of Anodic Aluminum Oxide in Galvanostatic and Galvanostatic-Potentiostatic Modes

The results are presented of obtaining anodic aluminum oxide with an ordered pore arrangement by employing two anodizing modes - galvanostatic mode and combined (galvanostatic + potentiostatic) mode, at high values of the current density and voltage. Use has been made of an oxalate electrolyte and a complex electrolyte comprising oxalic acid and phosphoric acid. Scanning electron microscopy has been used to investigate the surface morphology of the barrier and porous layers and to determine pore sizes and inter-pore distance.

Anodizing for Design and Function

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.

The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films

The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.
