Smart Investigation on Nanocomposites Composed of Carbon Dioxide-Derived, Repeatable Biological Polymers – A review

In recent years, an increasing number of people have begun to focus their attention on the environmental impacts that are caused by the widespread use of therapeutic polymeric composites that are generated from fossil energy. Another factor that probably contributes to the short shelf life of biomedical polymer products is the fact that many of them are designed to be used just once before being discarded. When a biomedical polymer product goes over its sell-by date, it must often be burned before being discarded, increasing carbon dioxide emissions (CO2). By ultimately replacing their unsustainable fossil-based equivalents, biomedical goods based on polymers produced from CO2 fixation would improve CO2 recycling in this industry and aid in the mitigation of the greenhouse effect. However, the bulk of presently available polymer materials manufactured from renewable raw materials do not satisfy these expectations due to a number of property deficiencies, and the superiority and stuff values for biomedical devices are constantly expanding. The materials don’t have the essential characteristics to satisfy the requirements. Many people are trying to apply nanotechnology in this field due to these problems. In addition to discussing replicable CO2-fixed polymer-based nanocomposites that may be used in biological applications, this work gives a number of intriguing suggestions for further research areas in this field.

Buckling Assessment of Concrete Column, RCC Column and Concrete Column Strengthened by CFRP with Different Slenderness Ratio

Using finite element modeling, this study presents a buckling analysis and total deformation assessment of a concrete column, a column made of reinforced cement concrete (RCC), and a concrete column enhanced with Carbon Fiber-reinforced Polymer (CFRP) laminates (FEM). Utilizing the ansys18.1 software, a comprehensive analysis is carried out for columns that have a variety of slenderness ratios to arrive at a more accurate performance estimation. Because they can support the most weight overall, RCC columns are among the most important components of a building’s structure. On the other hand, because of the enormous compressive load, these structures risk failing owing to buckling. There is a greater likelihood of rapid buckling occurring in the columns that have a high slender ratio. As a result, it is essential to investigate and evaluate the effects of an excessive load on several separate columns, each of which has a distinct slenderness ratio. For this study, the slenderness ratios were determined to be 20, 30, and 40 for concrete columns, RCC columns, and RCC columns reinforced with CFRP. The findings indicate that the load-bearing capability of the columns can be improved by increasing the quantity of CFRP sheets used in their construction.
