AuNPs
Gold nanoparticles (AuNPs) have gained high prominence in the biomedicine field, due to their own physico-chemical properties that are suitable for different imaging or therapeutic uses, versatile structural modification, including easy functionalization of their surface with different chemical entities (e.g., chelators, targeting biomolecules or cytotoxic drugs), favourable biological half-life, low toxicity and biocompatibility. In particular, the use of AuNPs in radiopharmaceutical development has provided various nanometric platforms for the delivery of medically relevant radioisotopes for SPECT/PET diagnosis and/or radionuclide therapy

AuNPs and Fibrous Materials
The use of nanoparticles is a multidisciplinary approach to provide UV blocking, antimicrobial, water repellent, colorant, flame retardant, sensing, and self-cleaning properties to textiles. Particularly, the antimicrobial textiles with improved functionalities find several applications, namely, in health and hygiene products, infection control, and barrier material. Depositing nanoparticles in textiles have been a promising strategy to achieve multifunctional materials. Particularly, antimicrobial properties are highly valuable due to the emergence of new pathogens and the spread of existing ones. Various techniques have been used by researchers to functionalize natural and synthetic fibers with AuNPs such as sputtering, electrostatic assembly, chemical reduction in solution, dip-coating, electroless plating, drop and dry, biosynthesis, and print pasting method.

Aurilide Family
Aurilides are a class of depsipeptides occurring mainly in marine cyanobacteria. Members of the aurilide family have shown to exhibit strong cytotoxicity against various cancer cell lines. These compounds bear a pentapeptide, a polyketide, and an α-hydroxy ester subunit in their structure.

Aurivillius-Phase Bi4Ti3O12-nBiFeO3 Materials
Aurivillius-type layered compound have attracted increasing research interest, especially in recent 20 years, due to their promising electrical properties as new lead-free piezoelectric materials operating at high temperatures. For instance, the well-known Bi4Ti3O12, presents large spontaneous polarization, anisotropy and high ferroelectric Curie temperature and have wide applications in the electronic industry, capacitors, transducers, nonvolatile ferroelectric memories, piezoelectric sensors and optical devices. To increase functionality of Bi4Ti3O12 modification with BiFeO3 is very promising, which is also a methodology for constructing single-phase multiferroics in which ferrelectricity and magnetic ordering are coupled near room temperature. Combining these two materials exhibiting different physical performances one can create a kind of novel materials and thus achieve functionality. Herein, we summarized the recent progress in the field of synthesis of BFTO-n materials with various architectures and highlighted their extraordinary properties for promising applications in the electronic industry, quantum devices, capacitors, transducers, microwave absorbers, catalysts and photoelectric devices.

Austenite in Advanced High Strength Steels
Advanced high strength steels (AHSS) are developed to reduce vehicle weight without sacrificing passenger safety. The newly developed AHSS frequently incorporates the austenite as the intrinsic component with large amount and good stability, which is realized by carefully designed alloying elements and thermo-mechanical processing.

Biography
Austin James Barnes
Austin James Barnes was born in Blackpool on 2 June 1945. He went to Gonville and Caius College, Cambridge, in 1963 and obtained his BA degree in 1966. He then moved to the University College of Swansea, where he was awarded his PhD degree in 1969 for research on the infrared spectra of matrix-isolated species under the supervision of the late Harry Hallam. After a period of postdoctoral researc

Autophagy Modulators
Autophagy modulation is considered to be a promising programmed cell death mechanism to prevent and cure a great number of disorders and diseases. The crucial step in designing an effective therapeutic approach is to understand the correct and accurate causes of diseases and to understand whether autophagy plays a cytoprotective or cytotoxic/cytostatic role in the progression and prevention of disease. This knowledge will help scientists find approaches to manipulate tumor and pathologic cells in order to enhance cellular sensitivity to therapeutics and treat them. Although some conventional therapeutics suffer from poor solubility, bioavailability and controlled release mechanisms, it appears that novel nanoplatforms overcome these obstacles and have led to the design of a theranostic-controlled drug release system with high solubility and active targeting and stimuli-responsive potentials.

Available Sampling Methods for Plastic Waste
Given the rapid development of plastics recycling in recent years, the need for guidelines for sampling and material characterization is steadily emerging. However, there still exists a considerable scarcity of methods that enable proper material data acquisition. It was found that neither the literature nor the standards provide a comprehensive practice that considers the distinctive characteristics of plastic waste and applies it to different situations along the value chain. Two variants of the proposed plan were evaluated based on the flake size distribution and the apparent density of four different pretreated polyolefin (PO) waste materials. Combining stratified random sampling with composite sampling yields a good sampling technique for rigid PO waste. Moreover, the analysis of a composite sample adequately conveys the true material properties of a sublot or lot.
