The concept of green hydrogels in forensics is a budding area where it encompasses the concept of sustainable investigation. Motivated by the need to prepare for the next generation advanced materials for implementing proactive forensic science strategy. The work conception, already successful in a few fields, aimed at implementing the sophisticated criminal's way of thinking, predicting their next move so that the crime‐fighting authorities can be one step ahead of them and take precautionary actions. The existing problems of current society need to be solved by deliberate efforts of researchers and forensic experts, as we can formulate strategy of design, production, and characterization of innovative polymeric materials for on spot detection of traces. Various innovative materials have been explored with the help of green chemistry. Fingerprinted products that are unique in their compilation are made in forensics by utilizing the concept of green chemistry. The creation of nontoxic hydrogels by utilizing green polymers that are biodegradable, biocompatible, and bio renewable is one such field that helps in forensic applications. The distinctive properties of hydrogels make them suitable for various forensic investigations. In this review article, we have focused on the unique sparked properties of these smart gels and opened a gateway in solving various unsolved mysteries.

“…Trying to achieve DQOs for studies conducted in the harsh marine environment (in which mineral oils are subject to, e.g., photolytic reactions, volatilization, biodegradation) can be particularly daunting [30]. Confoundingly, the frequent need for an immediate response to a spill can hamper the planning process.…”

“…QC samples typically collected as part of a well-conceived sampling program include [18]: Unlike standard sampling methods that are often available for chemical analysis, standard methods for collecting samples in marine matrices do not exist. When using non-standard sampling methods for marine mineral oil spill research, understanding and applying methodologies used and accepted by other researchers can be key to implementing a reliable sampling program [30]. Accepted practices for sampling mineral oils [35], sediments [36], water column [37], and ecological samples [38,39] have been discussed elsewhere.…”

Spilled mineral oils in the marine environment pose a number of challenges to sampling and analysis. Mineral oils are complex assemblages of hydrocarbons and additives, the composition of which can vary considerably depending on the source oil and product specifications. Further, the marine microbial and chemical environment can be harsh and variable over short times and distances, producing a rigorous source of hydrocarbon degradation of a mineral oil assemblage. Researchers must ensure that any measurements used to determine the nature and extent of the oil release, the fate and transport of the mineral oil constituents, and any resultant toxicological effects are derived using representative data that adhere to the study’s data quality objectives (DQOs). The purpose of this paper is to provide guidance for crafting obtainable DQOs and provide insights into producing reliable results that properly underpin researchers’ findings when scrutinized by others.

“…Oil pipelines are often buried underground or placed in locations that are difficult for maintenance personnel to reach, such as the seabed. Oil leaks are usually not detected in time, and large quantities of leaking oil can cause damage to the natural environment and huge economic losses to transport companies [12][13][14]. In order to avoid the occurrence of oil pipeline leakage accidents, it is necessary to check the internal condition of the pipeline regularly.…”

Leaf spring calipers are a kind of pipe detector that installs strain gauges on the detecting arm, and the strain gauges measure the geometrical dimensions of the inner wall of the pipe by detecting the bending strain of the leaf spring and the sensors of the leaf spring caliper are set up on the detecting arm, so it has higher detecting accuracy and smaller structural dimensions. Leaf spring calipers are widely used because of their outstanding advantages, but their detection arms are worn out, and their detection accuracy increases with the detection distance. In this paper, we establish a wear model of the detection arm for the operation of the leaf spring caliper in crude oil and refined product pipelines, and according to the model, we build a wear test system for the detection arm. The wear test system of the inspection arm simulates the wear between the inspection arm made of G61500 (UNIFIED NUMBERING SYSTEM) material and the pipe made of X80 (API SPEC 5L) material. The wear pattern of the inspection arm in crude oil and refined oil pipelines is investigated by adding lubricating media with similar physical parameters to crude oil and refined oil, such as light mineral oil, SAE 5W-30 lubricant, 600XP 680 lubricant. The experimental results are analyzed to explore the wear performance of the leaf spring caliper arm, and the prediction algorithm is used to predict the wear pattern of the leaf spring after lubrication. The results show that the average error between the predicted and actual values meets the accuracy requirements, and the wear prediction model of the detection arm can be used as a correction algorithm for the wear error of the leaf spring caliper to improve the detection accuracy.
