Advanced Strategies for 3D Bioprinting of Tissue and Organs Analogs Using Alginate Hydrogel Bioinks

Alginate is a natural polysaccharide that typically originates from various species of algae. Due to its low cost, good biocompatibility, and rapid ionic gelation, the alginate hydrogel has become a good option of bioink source for 3D bioprinting. However, the lack of cell adhesive moieties, erratic biodegradability, and poor printability are the critical limitations of alginate hydrogel bioink. This review discusses the pivotal properties of alginate hydrogel as a bioink for 3D bioprinting technologies. Afterward, a variety of advanced material formulations and biofabrication strategies that have recently been developed to overcome the drawbacks of alginate hydrogel bioink will be focused on. In addition, the applications of these advanced solutions for 3D bioprinting of tissue/organ mimicries such as regenerative implants and in vitro tissue models using alginate-based bioink will be systematically summarized.

Armbrusterite as an advanced material for modern science of materials

The description of a new and insufficiently studied mineral armbrusterite is presented in this paper. The mineral was analyzed from the point of view of its chemical properties and prospects for practical application. The mineral's sorption properties for arsenic and cesium ions were studied. The possibility of synthesis an analog of the mineral due to hydrothermal synthesis was estimated

Application Of Hybrid Fibre Concrete As Advanced Material For Concrete Water Tank Construction

The challenge of construction and the complexity of civil engineering systems, especially in the construction of water tanks, are catching people’s attention around the world. Concrete, which is a priority feature and a mandatory used material, must have a very high strength and an acceptable degree of workability and properties. Efforts are being made in the field of concrete production to create and expand these mixtures of unusual characteristics and behaviors. The used of the hybrid fibre concrete in the concrete wall can reduce the costing factor in terms of constructions and maintenances beside that the quality assurance is highlighted. In addition, the sustainability in the water tank construction in Malaysia can be achieved using the advanced material in the construction.

Recent advances in immunoassays and biosensors for mycotoxins detection in feedstuffs and foods

Mycotoxins are secondary metabolites produced by fungus. Many mycotoxin species are highly toxic and are frequently found in cereals and feedstuffs. So, powerful detection methods are vital and effective ways to prevent feed contamination. Traditional detection methods can no longer meet the needs of massive, real-time, simple, and fast mycotoxin monitoring. Rapid detection methods based on advanced material and sensor technology are the future trend. In this review, we highlight recent progress of mycotoxin rapid detection strategies in feedstuffs and foods, especially for simultaneous multiplex mycotoxin determination. Immunoassays, biosensors, and the prominent roles of nanomaterials are introduced. The principles of different types of recognition and signal transduction are explained, and the merits and pitfalls of these methods are compared. Furthermore, limitations and challenges of existing rapid sensing strategies and perspectives of future research are discussed.

Remediation of Diethyl Phthalate in Aqueous Effluents with TiO2-Supported Rh0 Nanoparticles as Multicatalytic Materials

An innovative “domino” process, based on an arene hydrogenation followed by a photocatalytic step, was designed for the remediation of endocrine disrupting compounds, in highly concentrated aqueous effluents. The novelty relies on the use of TiO2-supported zerovalent Rh nanoparticles as multicatalytic materials (MCMs) for this two-step treatment, applied on diethyl phthalate, which is a model aromatic pollutant frequently present in aquatic environments. This nanocomposite advanced material, which was easily prepared by a green, wet impregnation methodology, proved to be active in the successive reactions, the reduction in the aromatic ring, and the photodegradation step. This sustainable approach offers promising alternatives in the case of photoresistive compounds.

It combines village and school concepts with the selection of beginner, intermediate, and advanced material.

Biomimicry and the Built Environment, Learning from Nature’s Solutions

The growing interest in biomimicry in built environments highlights the awareness raised among designers on the potentials nature offers to human and system function improvements. Biomimicry has been widely utilized in advanced material technology. However, its potential in sustainable architecture and construction has yet to be discussed in depth. Thus, this study offers a comprehensive review of the use of biomimicry in architecture and structural engineering. It also reviews the methods in which biomimicry assists in achieving efficient, sustainable built environments. The first part of this review paper introduces the concept of biomimicry historically and practically, discusses the use of biomimicry in design and architecture, provides a comprehensive overview of the potential and benefits of biomimicry in architecture, and explores how biomimicry can be utilized in building envelops. Then, in the second part, the integration of biomimicry in structural engineering and construction is thoroughly explained through several case studies. Finally, biomimicry in architectural and structural design of built environments in creating climate-sensitive and energy-efficient design is explained.
