Corrosion poses a persistent challenge in acidic environments, necessitating the exploration of effective corrosion inhibitors. This mini-review focuses on the utilization of heterocyclic compounds as corrosion inhibitors in acidic solutions. Beginning with an overview of corrosion mechanisms in acidic environments, we delve into the diverse array of heterocyclic compounds investigated for their corrosion inhibition properties. Emphasis is placed on elucidating the mechanisms through which these compounds mitigate corrosion, ranging from surface adsorption to film formation. Recent advancements in the field are highlighted, showcasing novel compounds and formulations exhibiting promising results. A comparative analysis evaluates the effectiveness of various heterocyclic compounds, considering factors such as inhibition efficiency, cost, and environmental considerations. Despite notable successes, challenges and limitations are discussed, paving the way for future research directions. In conclusion, this mini-review underscores the significant strides made in harnessing heterocyclic compounds as corrosion inhibitors, offering a glimpse into their potential impact on addressing corrosion challenges in acidic environments.

Coil spring suspension systems are widely used in various applications, including automotive, industrial, and aerospace engineering. The spring, bearing, piston rod, seal block, rebound adjuster, and hydraulic oil make up the suspension system. The suspension system's main purposes include increasing the amount of contact time between the tyres and the road. It supports the vehicle's weight evenly and offers stable steering and good handling. The principle of force dissipation, which involves converting force into heat and thereby eliminating the impact that force would have made, underlies how a suspension operates. The energy will be stored by a spring and transformed into heat by a damper. By applying a theoretical method to determine the deflection of coil spring suspension system in this paper. Here mainly focus on the basic coil spring model which is the main part of suspension system. It also aids in the bike and rider's ability to absorb significant shocks when executing jumps. For designing of coil spring suspension system 3D software Solid works is used. For analysis of the model ANSYS workbench is implemented. Using standard theoretical data, analytical & simulation results are compared & mesh convergence graph study is also done in this paper.

The most significant variable in all metal forming processes is the formability of the material. The degree of difficulty determined by this variable is essential for lubricant selection. It is expected that a lubricant will facilitate the sliding of the workpiece in the tool by reducing friction and, at the same time will provide an effective separation layer between the workpiece and the tool.Therefore, in this article, the results of scientific research on preventing damage to the metal sheet surface by lubrication are described in detail.

Heavy metal removal using adsorbent materials like watermelon rind, as investigated herein, will ensure a safe drinking water for consumption. For the first time, mathematical models taking A = adsorbent dosage, B = contact time and C = initial concentration as input variables were developed using Stat-Ease 360 design of experiment (DOE) tool for adsorption capacity (R1) and percent removal of heavy metals including, arsenic, cadmium, chromium, copper and lead (R2) in water, as two sole output variables. The models generated based on existing experimental observations (A, B, C) can be used to predict the responses or outputs of the adsorption process, especially looking at their respective satisfactory statistical performance parameters obtained. Several 3D surface and contour plots reveal the optimal factor combination for peak response performance for a particular metallic contaminant in the water. Optimal values for arsenic removal are 0.1g A, 120 min B, 3.12 mg/g R1 and 100% R2. Those of other metals present are as follows: 0.1g A, 60 min B, 0.17 mg/L C, 144.75 mg/g R1 and 85.78% R2 for cadmium; 0.1-1.2g A, 0

Nowadays, the world is running behind power generation as well as power saving. In the lighting industry, the L.E.D. bulb is used for lighting purposes. The main problem faced by the world is heat dissipation from a heat sink by active or passive cooling. The system accessories enhance the overall cost by using active cooling. This paper studied that it has been used to reduce the overall cost of L.E.D. bulbs by increasing the heat transfer rate concerning increasing heat transfer coefficient. It needs to understand the various parameters such as porosity, heat transfer rate, laminar flow, density, and heat transfer modes to achieve the above-desired result. Their application is for street lights, gardens, mall parking, and bulging decorative lights. The cross-shape fin array is a suitable replacement with porosity of more than 0.85 for a proper swirl during the cooling time for an active cooling system for an existing bulb.

The objective of this research is to upgrade the low-grade Gariti barite ore to produce an ultrafine engineering material that can be used for industrial application by the assessing gravity concentration method. The research focuses on chemical characterization, fractional sieve size analysis, scrubbing technique, wilfley shaking table technique, and air float technique. The sample was subjected to an energy-dispersive X-ray fluorescence spectrometer and fractional sieve analysis of the crude sample was carried out at a sieve range of 1400-63 µm towards the production of ultrafine mineral-based material for liberation size determination. Ten (10) kg, each of the actual liberation size were used for the scrubbing technique, wilfley shaking table technique, and air float technique respectively. The chemical analysis indicates the presence of major elements 79.20 % BaSO4, 14.4% SO3, 64.80% BaO, 3.80% Fe2O3, 5.15% SiO2, 1.40% TiO2, and other minor elements that confirms that the soured mineral is barite while the particle size analysis showed that -250+ 180 µm sieve size fraction assaying 89.11% BaSO4 is the ore’s actual liberation size. The chemical analysis of the low-grade Gariti Barite ore after undergoing a concentration test at the economic liberation size revealed the values of concentrates from the scrubbing technique to be 86.60% BaSO4, Wilfley shaking table technique to be 86.10% BaSO4, and air float technique to be 88.30% BaSO4 and from this results, it shows that air float technique had the highest assaying value. Finally, the low-grade Gariti barite ore has been upgraded from 79.20% BaSO4 to ultrafine mineral-based engineering material of 86.60%, 48.6% 86.10%, and 88.30% BaSO4 via gravity concentration method.
