The aim of controlling/regulating cellular processes by surface patterning of biomaterials is a crucial concept in emerging research fields, where the precise fabrication of micro-nano surface topographies is required at manufacturing scales to meet consumer demand. Photolithography is typically employed for surface patterning; however, the high cost, process complexity, and lack of environmentally friendly and sustainable methodologies represent steep barriers for many researchers. Soft lithographic methods have been utilised extensively as a potential alternative for traditional photolithography, yet a photolithographic step is still required for initial template fabrication. Here, we demonstrate the use of repurposed optical consumer items such as DVDs, diffraction glasses, and gratings that would otherwise be thrown away after their useful lives, being used here as a sustainable approach as templates for the formation of complex nano-patterns. By replicating these templates in polydimethylsiloxane (PDMS) and polylactic acid (PLA), we show the varied interactions of human aortic smooth muscle cells (HAoSMC) to these surfaces. Notably, it was demonstrated that, in comparison to nonpatterned substrates, HAoSMC interaction (adhesion, spreading, and viability) was higher on DVD patterned surfaces compared to diffraction glass and grating patterned surfaces according to the results from cell metabolic activity (MTT and Alamar Blue), and proliferation (total DNA) assays. We demonstrate that a simple, reusable, inexpensive, yet robust technology could be a powerful tool in improving our understanding of cell-surface interactions and for the potential development of medical devices with micro- and nanoscale low or high adhesion features

Background: The smell in a hospital is an amalgam of smells, emanating from varied sources. But primarily the smell is from the strong cleaning agents used in corridors, including phenyl and bleaching powder, etc. Chemicals that trigger odors may cause health effects. A strong urine odor is also responsible for foul smells in hospitals and other public facilities. Strong odors may cause some people to feel a burning sensation, leading to coughing, wheezing, or other breathing problems.

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 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.

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.

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.

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 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.
