Section Collection Information

Dear Colleagues,

New polymer materials, including blends and mixtures, continue to be developed as new applications and uses are being realized. The development of new materials often means that new polymer analysis and characterization techniques need to be developed as well. This is necessary because the new materials have unique features that cannot be adequately measured and defined using traditional characterization methods. Thus, the new analysis and characterization methodologies are required to guarantee that the most important property of the new materials is identified. These developments will allow for the effective use and implementation of the novel and unique materials in challenging applications.

To allow for the dissemination and discussion of polymer analysis and characterization techniques we are interested in work that has been done in the establishment of new technologies to identify the important features of new materials. Conversely, if an established technique has been modified or updated in some way to deal with the challenges of today, we are also interested in hearing about those results as well.

In order to achieve this goal, it is essential to collect the work of various researchers in the field of polymer analysis and characterization techniques. Both research articles as well as reviews are welcome on this topic.

We look forward to receiving your contributions.

Organic sensing element approach in electrochemical sensor for automated and accurate pesticides detection

Saira Bano;Prasanta Kumar Sahu;Vinod Kumar;Vandana Kumari;Akanksha Gupta;Ravi Kant;Ravinder Kumar;

The primary component for human health is food quality and its safety. The world has crossed 8 billion population highlighting major demand to fulfil high consumption food requirement. To overcome food security issue, inorganic farming trend is booming. In the process of boosting agriculture and allied products, unethical practices of using pesticides achieve heights. Protection of plants is necessary from weeds and pests. Thus, in order, to minimize the curb of unwanted growth of weeds and pest attack, pesticides act as an agent for protection and helping for immense production of crops. Therefore, swift and precise detection of harmful pesticides in agriculture products is required in urgent demand. In this review, the distinct organic material-based sensor such as colorimetric sensing, fluorescent sensors, gas chromatography-mass spectrometry, and liquid chromatography, with the organic compounds as sensing elements to monitor pesticides level in distinct samples due to their specificity, reusability, stability, high sensitivity, and selectivity. Apart from it, this study provides a comprehensive overview of the recent major advancement in organic sensing elements in electrochemical sensor pesticides detection based on molecularly imprinted, multimodal sensor polydopamine and conductive polymer at low-cost production.

Toxic metal ions present in environmental water samples and other samples need to be detected for their removal. The detection of trace metal ions using an ion selective electrode (ISE) holds great significance in analytical chemistry. A 4-vinyl pyridine-ethyl acrylate copolymer-polyvinyl chloride (VE-PVC) based polymeric matrix (electrode) has been fabricated by free radical bulk polymerization method which is an example of a green and sustainable method capable of detecting Ni2+ ions even in trace amounts. To fabricate the polymeric matrix (electrode) (PME), VE has been used as an ionophore. Further, the effectiveness of Ni2+ ion ISE has also been investigated in the presence of surfactants and detergents. Its performance has also been analyzed in the presence of plasticizers. The electrode is found to be very useful for the estimation of Ni2+ ions using ethylenediaminetetraacetic acid by potentiometric titration and also in the estimation of presence of Ni2+ ions in water. Compared to other metal ions, the fabricated membrane electrode developed in this work has been found to show efficient and better selectivity towards Ni2+ ions.

Chemistry in biosystem—A contemporary review of Schiff bases and their metal complexes as antioxidants and anti-fungal agents

Shallu Sachdeva;Neelu Dheer;Sunita Hooda;Neeti Misra;Bipasa Arya;Manisha Verma;Sangeeta Kaul;

Schiff bases are a class of organic compounds which have good chelating properties. Due to this, they can form complexes with metal ions of the transition series. Schiff bases and their derivatives are bioactive and hence find widespread uses in various fields of inorganic, organic and medicinal chemistry. These are synthesised by condensation reactions and have been studied extensively as they can exhibit biological properties like anti-oxidant, anti-fungal, anti-cancer, anti-bacterial and anti-microbial, apart from finding uses in the field of material science. With the advent of nanotechnology and its increasing importance, the introduction of nanoparticles of Schiff bases can increase the effectiveness of their various biological properties. In the present article, we aim at providing an exhaustive review of the behaviour of metal complexes of Schiff bases and their various derivatives as anti-oxidant and anti-fungal agents. The most pertinent and contemporary literature has been chosen for this review article.

Complex dielectric-impedance spectroscopic studies of magnetite added chitin biopolymer

Ishwar Prasad Sahu;Sanjeeta Rani;Sunita Hooda;Neelu Dheer;V Bhasker Raj;Manisha Verma;

We have successfully synthesized magnetic chitin (MCH) by incorporating iron oxide nanoparticles into biodegradable and abundantly naturally available chitin by the coprecipitation method. X-ray diffraction (XRD) characterization revealed formation of cubic inverse spinel structure of Fe3O4 nanoparticles. In addition to this, other characterization studies like energy dispersive X-ray analysis (EDX) and vibrating sample magnetometry (VSM) were also performed to have an insight into the compositional and functional nature of the structure. A detailed spectroscopic study of complex impedance and dielectric constant for a wide frequency range of ~1 Hz to 10 MHz at discrete temperatures ~300–400 K has been performed by us for the first time on MCH in order to understand various relaxation processes. From permittivity, we have estimated the height of the potential barrier to be ~95.8 ± 0.3 meV. Impedance measurements yielded an activation energy of ~35.85 meV. Thermogravimetric analysis (TGA) of the sample showed exceptionally high thermal stability of the sample with percentage of residual mass at 800 ℃ being ~73% in MCH, which is quite high in comparison to the pristine chitin. An S shaped curve obtained through VSM measurement confirmed the superparamagnetic nature of the nanocomposite. The study assumes significance in the present scenario of rising awareness about the environment and demand to explore alternative green materials with numerous biomedical/environmental applications ranging from drug delivery vehicles in COVID-19 treatment to food packaging.

Peptide chemistry has emerged as one of the growing fields of research. Peptide chemistry has positively impacted various areas, including biochemistry, medicine, hormonal therapy, drug delivery, food and the cosmetic industry, materials science, and nanotechnology, via the development of ways to change and imitate the shape and function of peptide structures. The structural changes of peptides and the employment of innovative synthetic techniques have left an indelible mark on a number of scientific disciplines. Numerous nanostructures based on simple and complicated peptides have been constructed so far; however, cyclic peptides have attracted a great deal of interest from the scientific community due to their wide range of applications and distinctive properties. These properties include self-assembly, morphogenesis, and charge distribution, among others. In addition, nanostructured cyclic peptides offer increased and effective performance due to their high stability, prolonged plasma half-life, membrane permeability, and efficient transport, among other attributes. Recent work indicates the manufacture of nanostructured cyclic peptides by chemical means. In this review, a brief investigation of the morphology of cyclic peptides was conducted. In addition, the therapeutic potential of these nanostructured cyclic peptides and the prognosis for a variety of potential applications are also discussed.
