Versatile Polyaniline-Based Polymers in Food Industry
Intrinsically conducting polymers (ICPs) have been widely studied in various applications, such as sensors, tissue engineering, drug delivery, and semiconductors. Specifically, polyaniline (PANI) stands out in food industry applications due to its advantageous reversible redox properties, electrical conductivity, and simple modification. The rising concerns about food safety and security have encouraged the development of PANI as an antioxidant, antimicrobial agent, food freshness indicator, and electronic nose. At the same time, it plays an important role in food safety control to ensure the quality of food.

Sensing Surfaces for Capacitive Biodetection
Affinity-based biosensors operate by specifically capturing a biological target with biological or synthetic capture agents such as aptamers, DNAzymes, single stranded DNAs or antibodies. Despite their high sensitivity and their suitability for miniaturization, biosensors are still limited for clinical applications due to the lack of reproducibility and specificity of their detection performance. The design and preparation of sensing surfaces are suspected to be a cause of these limitations.

Gastrin-Releasing Peptide Receptor  Targeting and Nanosystems
Advances in nanomedicine bring the attention of researchers to the molecular targets that can play a major role in the development of novel therapeutic and diagnostic modalities for cancer management. The choice of a proper molecular target can decide the efficacy of the treatment and endorse the personalized medicine approach. Gastrin-releasing peptide receptor (GRPR) is a G-protein-coupled membrane receptor, well known to be overexpressed in numerous malignancies including pancreatic, prostate, breast, lung, colon, cervical, and gastrointestinal cancers. Therefore, many research groups express a deep interest in targeting GRPR with their nanoformulations. A broad spectrum of the GRPR ligands as well as methods of their incorporation with the various delivery vehicles have been described in the literature. Proper design allows tuning of the properties of the final formulation, particularly in the field of the ligand affinity to the receptor and internalization possibilities.

Polymer-Based Composites for Electromagnetic Shielding Application
Traditional metals and alloys are often used for electromagnetic interference (EMI) shielding due to their excellent electrical conductivity. However, they have drawbacks such as being heavy, expensive, and having low corrosion resistance, which limits their application in electromagnetic shielding. Therefore, it is crucial to develop novel EMI shielding materials. Polymers, being highly flexible, corrosion-resistant, and possessing high specific strength, are frequently employed in electromagnetic shielding materials.

Manganese Oxide Carbon-Based Nanocomposite
The application of Manganese oxide (denoted as MnOx hereafter) in SCs was first reported in 1999. Since then, MnOx has been widely studied as an active, low-cost, and biofriendly ECs material. Why are manganese or its oxides are so appealing for SCs applications? First, manganese is a transition metal with five unpaired electrons, which possesses the most oxidation states, including the highest oxidation state (VII) in the entire periodic table. Due to its unique electronic structure, manganese is extremely redox-active, thus, it exists in several oxide forms. Second, Manganese is the most abundant transition metal among oxides which are pseudocapacitive. Third, MnOx exhibits high theoretical capacitance (1370 F/g for MnO2 for instance) with a wide positive potential window compared to other transition metal oxides.

Bimodal Nanostructure
Nanocrystalline metals developed based on fine grain strengthening always have excellent strength, but are accompanied by a drop in ductility. Substantial efforts have been dedicated to design new microstructures and develop the corresponding processing technologies in order to solve this problem. One of the novel nanostructures is the bimodal grain size distribution nanostructure.

ODS FeCrAl Alloys
After the Fukushima nuclear accident, the development of new accident-tolerant fuel cladding materials has become a research hotspot around the world. Due to its outstanding corrosion resistance, radiation resistance, and creep properties at elevated temperatures, the oxide dispersion strengthened (ODS) FeCrAl alloy, as one of the most promising candidate materials for accident-tolerant fuel cladding, has been extensively studied during the past decade. In particular, the reasonable/optimized content of Cr is explained from the aspects of oxidation resistance, radiation resistance, and thermal stability. The essential role of the Al element in oxidation resistance, high-temperature stability, and workability was reviewed in detail. The roles of oxide-forming elements, i.e., Y (Y2O3), Ti, and Zr, and the solid solution strengthening element, i.e., W.

Electrochemical Aptasensors for Detection of Neurodegenerative Diseases Biomarkers
Neurodegenerative diseases (NDs) are becoming a major global health problem. They constitute an incurable diverse group of disorders characterized by the progressive degeneration of the structure and function of the central or peripheral nervous system. There is an enormous unmet demand worldwide for methods for the early detection of ND biomarkers. Among the various approaches reported so far, biosensors are powerful analytical implements that have been applied to detect biomarkers of NDs. Electrochemical aptasensors have been at the forefront of this development not only thanks to their low cost and simple design but also due to advances in nanomaterials modifying the surface of the transducers involved.

Analytical Techniques for Detection and Quantification of PFAS
The established methods for performing poly-fluoroalkyl substances (PFAS) analysis are based on Liquid Chromatography-Mass Spectrometry (LC-MS). Both the sample preparation and the development of the chromatographic set-up are crucial steps for reliable, precise, and accurate measurements. According to the literature, the conventional reverse phase separation stationary phase column is the most widely utilized approach. To improve the chromatographic performance, columns equipped with polar functionalized C18 alkyl chains were introduced.
