These are a blend of nanoscale materials and polymers that give rise to advanced mechanical, morphological, electrical, and structural properties. Generally, two-dimensional nanomaterials, such as nanofilms, nanosheets, nanoribbons, nanofillers, and carbon nanotubes, are fabricated with a wide range of organic, inorganic, and metal polymers to acquire desirable properties. The chemistry of these nanomaterial-based nanocomposites shows that even a small amount of nanomaterial in the polymer matrix can result in enhanced material properties. The dielectric, conductive and energy storage properties of these materials are also of significant importance. These nanomaterial-based polymer nanocomposites are next-generation materials that will be highly utilized for different purposes. The blend of existing polymers and advanced 2d nanocomposites has proven e...

The aim of this study was to determine (I) whether costal cartilage calcification pattern help in estimating sex in North Indian sample and (ii) whether there is any relation between age and costal cartilage calcification. Results The statistical probability of estimating peripheral pattern in male was 99.3%, and for females, it was 100% for central type of calcification. The minimum age where lower costal calcification was present was 22-year-old female and 21 years old male. The degree of calcification and age showed positive correlation; similarly, the value of spearman’s rho showed significant result (for whole sample rs = 0.911, p < 0.01 (for male subjects, it was rs = 0.921, p < 0.01; for females, it was rs = 0.905, p < 0.01)). Conclusions The degree of calcification is useful in estimating age groups and becomes more determined with advancing age. Prediction of sex by using radiologica...

DATA SOURCES and SYNTHESIS: The data is gathered by searching the articles in varioussearch engines which have been published between January 2010 to December 2020. A total of 20 studies were found eligible after following inclusion and exclusion criteria described in the below article. Prisma Guidelines and Prisma Flowchart was followed. CONCLUSION: Artificial intelligence (AI) is a technology that involves computerised algorithms to dichotomize complex data. AI is widely used in diagnostic imaging for detection and quantification of a clinical condition. This systematic review aimed to explain the role of AI with diagnostic imaging modality of radiology in forensic. AI technology is now widely used for age and sex estimation. Most of the AI models are based on machine learning (ML) programs, artificial neural network(ANN) and convolu...

These endocrine disrupting chemicals (EDCs) influence the normal activities of hormones secreted from the female hypothalamus, ovary, pituitary & uterus. The female reproductive disorders are mainly observed at embryonic or during fetal development and subsequently get matured during puberty. Various toxic chemicals and other pollutants interact with the chemical structure of the hormones and hence prolonged effects are seen at the cellular and molecular level of hormones resulting in disruption of secretion and function. Due to poor coordination of hormones and other reproductive organs of the body vital functions are compromised. Hence it’s highly significant to study and explore the toxicity of chemicals that play a key role in the malfunctioning of the female reproductive system. In this review, we are concerned about the infl...

Insecticides such as carbamate, organochlorine and pyrethroids helps protecting the crop from various insects, which ultimately leads to the better yield of agricultural products. But the main concern that comes out in such frequent practice is the adverse effects to the adjacent ecosystems. Especially, the very commonly used carbofuran, DDT, Cypermethrin and its adverse effects can be put forwarded as a potential example in this article. Apart from this, the scope of this article covers the mechanism of toxicity by insecticides to nontargeted organisms in the ecosystem, the recent developments in the analytical techniques considering HPLC and GC, the method of extraction and quantication of active component in sample. A comparison between GC and HPLC is done and the preferred instrumentation is concluded while considering the analysis o...

The power of various solvent systems to separate the constituents of selected sindoor samples was studied. Twenty solvent systems were examined from which a solvent system comprising butanol:propanol:water in the ratio 60:30:10 (v/v/v) was found to be the best, as it showed a high degree of separation of the constituents. also found that the best visualizing method for studying TlC chromatograms of sindoor samples is the iodine fuming technique.

Morphological and binding characterization was performed to ensure the efficient synthesis of imprinted sol-gel. The imprinted sol-gel was found to exhibit higher binding affinity in comparison to non-imprinted sol gel. Method exhibit good linearity with R 2 value of 0.998 and 0.999 for fast garnet base and dimethyl yellow respectively. The limit of detection and limit of quantitation were 0.029 and 0.097 ng g −1 for fast garnet base and 0.021 and 0.070 ng g −1 for dimethyl yellow, respectively. Recoveries of the dyes were found to be in the range of 80-91% at three different concentration levels.
