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.

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.

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.
Anodic Porous Alumina Array for Cyanine Fluorophore Cy3 Confinement
Self-organized anodic porous alumina films with hexagonal pore lattice have attracted a considerable attention for biological arrays and confinement of various organic probes dyes in solutions. A molecular structure with axial symmetry in bis-heterocyclic indole chains and conjugate system, such as cyanine fluorophore Cy3 dye, was investigated here with respect to its fluorescence when loaded in the anodic alumina pores.
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.
