Preparation of Silver Nanoparticles from Synthetic and Natural Sources: Remediation Model for PAHs

With a growing appetite for the applicability of metal nanoparticles in different areas such as electronics, catalysis, chemistry, energy and medicine, the advent of nanoscience and technology is gaining prominence. Wet chemical techniques typically synthesise metallic nanoparticles, where the chemicals used are most frequently poisonous and flammable. In this work, an attempt is made to

Because of their greater environmental protection than synthetic materials, the analysis of protein materials such as collagen, gelatin, albumin, and silk fibroin and keratin has been increasingly increased. For the production of keratin (Ker), alginate (Alg), and Ker/Alg blend microparticles, the water-in-oil (W/O) emulsification-diffusion method was used. The solutions of the Ker, Alg, and Ker/Alg

In high voltage applications, epoxy resin is commonly used as an insulating material. In order to improve its mechanical properties, ceramic fillers are often applied to the polymer matrix. But at the same time, the electrical properties are reduced by filler materials. So, it is obvious to detect the effect of fly ash reinforcement on

To increase the life of the ice-maker device with a broken helix upper dispenser in the field, parametric accelerated life testing (ALT) was used. A number of mechanical loads in the assembly were analysed using bond graphs and state equations. A generalised life-stress failure model with a new load definition was used to derive the

The Parametric Accelerated Life Test (ALT) was used to determine the life of a commercial refrigerator’s newly built compressor subjected to repeated pressure loading. It consists of (1) a product BX lifetime parametric ALT plan that will be X percent of the cumulative loss, (2) ALT load analysis, (3) a tailored sequence of parametric ALTs

The effect of Coir fibre on the rheological properties of asphaltic materials indigenous to Trinidad, namely Trinidad Lake Asphalt (TLA) and Trinidad Petroleum Bitumen (TPB), has been investigated for fatigue cracking and rutting resistance. This research provided strong rheological evidence for the ability to manufacture specially formulated TLA and TPB adapted Coir blends to meet

In order to move molten steel from a steel making furnace to a continuous casting unit, refractory-lined ladles are used in steel mills. The aim of this study is to optimise the ladle cycle to increase the service life of the liner. A deeper understanding of the lining thermal conditions during the varying stages of

Machine learning is a branch of Artificial Intelligence that is used effectively and reliably to determine the solution to a problem. In deciding on the intensity of artefacts for different industrial applications, identification of subsurface non-uniformity is essential. In order to detect anomalies in a wide variety of materials, non-stationary thermal wave imaging is emerging

Electromagnetic radiation (EMR) occurs when structural materials (hereinafter simply materials) of different origin are destroyed, caused by inhomogeneities (cracks, microcracks, structural elements) of different scale levels created during the destruction and cracking phase. In this situation, the production of electromagnetic radiation is attributable to the following processes: the interatomic distance, interstitial bonds, the appearance of
