Molecular Nanomaterials in Industrial Applications
Nanomaterials have not only become one of the ‘hottest’ areas in research and development all over the world but also attracted numerous considerations in the industrial sectors. This technology can be primarily defined by their functional properties which determine how they interact with other disciplines. Recently, it becomes an evolving field in material science, materials processing technology, mechanics, electronics, optics, medicine, energy and aerospace, plastics and textiles etc. This technology not only establishes an interdisciplinary and emerging domain that embraces physics, chemistry, engineering but also contributes to detection of diseases, better therapy options, and remarkable reduced health-care expenses. Molecular nanomaterials can also be applied in manufacturing through ultra-precision, development of nano-metric microscopic devices, biological structures, nano robots, super computers, industries and genetics etc. All materials or devices which are nanometer scale (dimensions of roughly 1 to 100 nm) structured are included in nanomaterials.

Milk Fat Globule Membrane (MFGM)
Milk fat globule membrane (MFGM) is an important component of milk lipids that showed several biological properties (such as anticarcinogenic, antimicrobial, anti-inflammatory, and anticholesterolemic activities). In this review we analyse the latest results obtained from comparative proteomic studies regarding the variations and the similarities of MFGM proteome across species and lactation stages. Infant formula supplementation with MFGM represents an interesting opportunity to implement the bioactive properties exerted by MFGM, in order to narrow the gap between human breast milk and infant formula.

Modified Starch-Based Adhesives
Consumer trends towards environmentally friendly products are driving plastics industries to investigate more benign alternatives to petroleum-based polymers. In the case of adhesives, one possibility to achieve sustainable production is to use non-toxic, low-cost starches as biodegradable raw materials for adhesive production. While native starch contains only hydroxyl groups and has limited scope, chemically modified starch shows superior water resistance properties for adhesive applications. Esterified starches, starches with ester substituents, can be feasibly produced and utilized to prepare bio-based adhesives with improved water resistance. Syntheses of esterified starch materials can involve esterification, transesterification, alkylation, acetylation, succinylation, or enzymatic reactions.

Product-Based Learning
The traditional teaching-learning process in higher education employs strategies that position students as recipients of information transmitted by the teacher, which is conceptualized as knowledge. However, the reality in which we live, including new generational groups’ characteristics, requires implementing training solutions that meet individuals' needs in the development of skills or know-how. Thus, deploying suitable solutions to society through a framework that forms individuals capable of continuously seeking knowledge, creating and innovating, is crucial. The "Reproduction of an Environment of Innovation in the Classroom" (RAIS) is a product-based learning and evaluation strategy where the student is actively involved in constructing and generating knowledge. It allows developing the programmatic competencies in engineering courses to attain a feasible product. The RAIS strategy has been applied in Physical chemistry for Chemical Engineers and Industrial Chemistry courses. Students successfully formulated a product using the know-how attained in each course. In addition, this strategy increased motivation compared to other traditional courses, developing the ability to deploy and find solutions in work environments with multidisciplinary groups.

Laboratory of Analytical Chemistry
The Laboratory of Analytical Chemistry was established in 1963 and is part of the Department of Physical, Analytical and Environmental Chemistry of the School of Chemistry in the Faculty of Sciences of Aristotle University of Thessaloniki (AUTh). Today the Laboratory has seven Faculty members: Six Professors (Aristidis Anthemidis, Stella Girousi, Victoria Samanidou, George Theodoridis, George Zachariadis, Anastasia-Stella Zotou), and two Assistant Professors (Paraskevas Tzanavaras and George Tsogkas). Its function is also supported by 1 member of the Technical Staff (Foteini Zougrou, MSc Chemist). The main subject of the Laboratory's teaching and research is analytical chemistry, namely the development, validation and application of new analytical methods, as well as the exploration of new instrumental techniques and innovative materials used in chemical analysis. Within the framework of the educational services provided by the Laboratory, a number of courses are offered in the undergraduate and postgraduate curricula. Besides the students of the Department of Chemistry, students of other departments of AUTh are also trained. The main research fields served by the faculty members of the Laboratory of Analytical Chemistry, include: SEPARATION AND HYPHENATED ANALYTICAL TECHNIQUES SPECTROSCOPIC, AUTOMATED AND MULTIELEMENTAL TECHNIQUES ELECTROANALYTICAL TECHNIQUES, SENSORS AND BIOSENSORS MODERN SAMPLE PREPARATION TECHNIQUES AND INNOVATIVE MATERIALS

Elongational Flow
Elongational flow is a particular kind of flow involved in many industrially relevant processing operations of thermoplastics (such as fiber spinning, film blowing, foaming and thermoforming) in which the velocity gradient develops in the same direction as the flow itself.

Reaction Mechanism of CO2 Methanation
The combustion of fossil fuels has led to a large amount of carbon dioxide emissions and increased greenhouse effect. Methanation of carbon dioxide can not only mitigate the greenhouse effect, but also utilize the hydrogen generated by renewable electricity such as wind, solar, tidal energy, and others, which could ameliorate the energy crisis to some extent. Highly efficient catalysts and processes are important to make CO2 methanation practical. Although noble metal catalysts exhibit higher catalytic activity and CH4 selectivity at low temperature, their large-scale industrial applications are limited by the high costs. Ni-based catalysts have attracted extensive attention due to their high activity, low cost, and abundance. At the same time, it is of great importance to study the mechanism of CO2 methanation on Ni-based catalysts in designing high-activity and stability catalysts.

Electron Transport Layer
The electron transport layer (ETL) acts as a function of collecting electrons and blocking the transport of holes to the FTO electrode in the PSC. The mesoporous structure of the ETL promotes the crystallization and film formation of perovskite and shortens the migration path of photogenerated electrons. A suitable ETL should have an energy band position that matches the perovskite material.

Electrospun Nanofibers: Basic Principles
Electrospun nanofibers had been gaining importance in several areas such as the biomedical, environmental, food, textile, and biotechnology industries, amongst others. The fabrication of three-dimensional membranes through the electrospinning technique confers several characteristics that are important in the above industrial approaches such as high-to-volume radio, high surface area, controllable porosity, thickness, and mechanical properties, also the non-toxicity, biocompatibility, and biodegradability can be conferred to the scaffolds by choosing the adequate polymeric formulation.
