Geopolymer Materials for Bone Tissue Applications
Geopolymers (alkali-activated materials) are amorphous inorganic polymeric systems with aluminosilicate bases produced by alkalinising natural or waste substances, such as metallurgical, industrial, urban, and agricultural wastes. There is increasing academic interest in geopolymer materials for biomedical applications.

Algae-Powered Buildings
Environmental pollution, global warming, energy consumption, and limited natural resources are some key factors from which the built environment faces interrelated problems and their management plays a vital role in sustainability. Application of bioactive elements on buildings’ façades is a novel approach for solving the problems. Algae building technology (ABT) is an innovative approach to energy efficiency in the built environment.

Carbon Nanotubes-Based Nano Materials
High modulus of about 1 TPa, high thermal conductivity of over 3000 W/mK, very low coefficient of thermal expansion (CTE), high electrical conductivity, self-lubricating characteristics and low density have made carbon nanotubes (CNTs) one of the best reinforcing materials of nano composites for advanced structural, industrial, high strength and wear-prone applications. This is so because it has the capacity of improving the mechanical, tribological, electrical, thermal and physical properties of nanocomposites.

Energy Efficiency Management in Small and Medium-Sized Enterprises
Energy efficiency is a key factor to meet the ambitious climate targets of the European Union (EU) aligned with the international policy directives. On their own, Small and Medium-sized Enterprises (SMEs) do not consume big amounts of energy, but taking into consideration that they represent about 99% of businesses worldwide, their cumulative energy consumption is remarkable. Even though SMEs experience several barriers in their effort to improve their energy efficiency, their contribution to the EU’s energy efficiency improvement targets is crucial through the implementation of measures to improve their energy footprint.

Microbial Enzyme Applied to Plastic Depolymerization
The accumulation of synthetic plastic waste in the environment has become a global concern. Microbial enzymes (purified or as whole-cell biocatalysts) represent emerging biotechnological tools for waste circularity; they can depolymerize materials into reusable building blocks, but their contribution must be considered within the context of present waste management practices.

Laser Ultrasonic in a Smart Manufacturing Production Site
The advancement of laser ultrasonics has increased rapidly, providing applications for materials characterization as well as for industrial utilization, as a quality control device. The wide-ranging capabilities for high-temperature in-situ analysis of a variety of microstructural characteristics offers a multitude of possibilities for usage in R&D. One possibility to investigate in a contactless manner, in-situ, and at high temperatures is the laser ultrasonic (LUS) method. This measurement technique has been developed over the last decades for many fields of application and can be used in various different configurations. This method can be applied to a variety of analyses known from the conventional ultrasonic technique. In particular, defect detection is one of the most common applications, especially the detection of defects in terms of pores, voids, or adhesion defects, especially in castings or welds. However, such defect detections are also of great advantage in additive manufacturing.

Reconfigurability with Metamaterials
Metamaterials exhibit properties in terms of subwavelength operation or phase manipulation, among others, that can be used in a variety of applications in 5G communication systems. The future and current 5G devices demand high efficiency, high data rate, computational capabilities, cost-effectiveness, compact size, and low power consumption. This variation and advancement are possible when the antenna design is revised to operate over wideband, high gain, and multiband and has characteristics of compact size, reconfiguration, absorption, and simple ease of fabrication. The materials loaded with antennas or, in the same cases, without antennas, offer the aforementioned characteristics to bring advancement in order to facilitate users.

Microbial-Induced Calcite Precipitation in Unsaturated Soil
Unsaturated soil is a form of natural soil whose pores are filled by air and water. Different from saturated soil, the microstructure of unsaturated soil consists of three phases, namely, the solid phase (soil particle), vapor phase, and liquid phase. Due to the matric suction of soil pores, the hydraulic and mechanical behaviors of unsaturated soils present a significant dependence on the moisture condition, which usually results in a series of unpredictable risks, including foundation settlement, landslide, and dam collapse. Microbial-induced calcite precipitation (MICP) is a novel and environmentally friendly technology that can improve the water stability of unsaturated soft or expansive soils.
