Summary: The novel glass ceramics for LTCC applications with high flexural strength were achieved through co-firing CaO-MgO-ZnOSiO2 (CMSZ) glass with Al2O3. The flexural strength of the CMZS/Al2O3 glass ceramics initially increases and then decreases with increasing Al2O3 content, with the best performance observed in the CMZS/Al2O3 glass ceramic containing 50 wt % Al2O3 sintered at 890 degrees C for 2 h, exhibiting a maximum flexural strength of 256 MPa.

Summary: This study investigates the effects of substituting K+ ion with Ca2+ or Sr2+ ion in K2O-SiO2-MgO-Al2O3-B2O3-MgF2-Li2O-AlPO4 glass, revealing that the presence of CaO or SrO decreases the density of the glass. Transparent glass monoliths and opaque glass-ceramics were obtained, with the predominant crystalline phase in the glass-ceramics identified as fluorophlogopite mica. The addition of CaO and SrO transformed the morphology of the mica crystals from plate-like to nanocrystalline with droplet-like spherical shapes.

Summary: High performance ultra-low temperature co-fired ceramics (ULTCC) were prepared using CuO-MgO-ZnO-Al2O3-B2O3-Li2O glass-ceramics. The substitution of ZnO with MgO improved the dielectric properties of the glass-ceramics due to the fine microstructure, high crystallinity, and decreased tetrahedral distortion. The sintering compatibility with Ag and Al electrodes was also demonstrated. These ULTCC materials have potential applications in the field.

Summary: The aim of this study is to evaluate the bioactive and tribological properties of the MgO doped borophosphate glass system. The addition of MgO promotes degradation of the glass and increases its bioactivity. In terms of tribological properties, the glass sample with 3% MgO exhibited the highest hardness and the lowest wear rate. MTT assay confirmed the non-toxic behavior of the glass samples. Therefore, MgO doped borophosphate glass shows potential for bone filling and wound healing applications.

Summary: Metal Additive Manufacturing (AM) has evolved from a rapid prototyping method to a viable manufacturing tool, attracting high-value industries for direct component production. However, the highly dynamic nature of the process often leads to defect formation and lack of control. This review explores the application of Machine Learning (ML) approaches and in-situ monitoring technologies for defect detection and discusses their potential for process control implementation. It also critically evaluates trends in data structures, ML algorithms, and sensing technologies in laser metal AM monitoring tasks, providing recommendations for further research.

Summary: In this study, a new model for reliable testing of three-units monolithic fixed dental prostheses (FDPs) was proposed, which is based on a novel design of the polymeric base realized via additive manufacturing. Three different analyses including analytical, numerical and experimental methods were conducted to thoroughly test the load-bearing capability of the FDPs. The findings demonstrated the advantages of the new base configuration in minimizing the stress state of the connectors and improving the repeatability and reliability of the experimental bending tests.

Summary: As scientists realized the potential of translating raw neurological signals into bioelectric information, massive growth has been witnessed in the field of brain-machine interfaces (BMI) for both experimental and clinical studies. The development of suitable materials to enable real-time recording and data digitalizing has three key requirements: biocompatibility, electrical conductivity, and mechanical properties similar to soft brain tissue. This review discusses the use of inorganic nanoparticles and intrinsically conducting polymers to enhance electrical conductivity, while soft materials like hydrogels offer reliable mechanical properties and a biocompatible substrate. Future goals include developing biohybrid conducting polymer-based interfaces loaded with cells for simultaneous stimulation and regeneration, as well as utilizing artificial intelligence and machine learning to design advanced materials for multi-modal BMIs.

Summary: Tissue engineering is a promising field in regenerative medicine that utilizes synthetic grafts like scaffolds to regenerate damaged tissues. Polymers and bioactive glasses are popular materials for scaffold production due to their adjustable properties and interaction with the body. Additive manufacturing is a promising method for producing scaffolds, but challenges remain in tailoring mechanical properties and achieving controlled degradation for successful tissue regeneration. This review summarizes the potential and limitations of using additive manufacturing techniques for polymer/bioactive glass scaffold production and emphasizes the importance of addressing current challenges in tissue engineering for reliable strategies.

Summary: The addition of chlorella or spirulina above 5wt% in ordinary Portland cement inhibits the hardening hydration reactions in the long term. Incorporating carbon-fixing materials like photosynthetic algae in concrete formulations can effectively reduce the high carbon footprint of cement. The introduction of up to 0.5 wt% chlorella biomatter in ordinary Portland cement delays the strength development of the composite cement while achieving a long-term compressive strength comparable to pure cement with a lower carbon footprint.

Summary: This study examines the combined effect of anethole and cisplatin on oral cancer therapy. Results show that anethole enhances cisplatin's inhibitory effect on oral cancer cell proliferation, inhibits cell migration, and induces apoptosis through caspase activation. Additionally, anethole and cisplatin increase the production of reactive oxygen species (ROS) and mitochondrial stress. The combination of anethole and cisplatin also inhibits major cancer signaling pathways, such as MAPKase, beta-catenin, and NF-kappa B, thereby enhancing cisplatin's cancer cell-killing effect and reducing associated side effects.

Summary: The mass production and disposal of non-degradable fossil-based plastics have led to significant environmental and social issues. Biopolymers, which are synthesized by living organisms, offer a promising sustainable alternative due to their attractive mechanical properties, compostability, and renewable sourcing. This review focuses on the structural and mechanical properties of three commonly studied biopolymer classes: cellulose, chitin, and protein beta-sheet structures. Various fabrication and processing methods are discussed to translate these properties into macroscopic materials and composites. Additionally, the use of microorganisms as building blocks for biomatter-based materials is explored, highlighting the role of hierarchical arrangement and processing-induced transformations in determining the macroscopic mechanical properties. The potential of biopolymers in a circular economy is also discussed.

Summary: This article describes a new class of interface-functionalised textile-reinforced mortar (TRM) composite materials that are reinforced with basalt and alkali-resistant glass multifilament textiles embedded in a commercially available hybrid lime-cement mortar. The mechanical performance, specifically the tensile strength, of the system is improved through a scalable and easy-to-apply surface treatment for the dry textiles. The treatment involves soaking the textiles in highly-diluted epoxy resin with the addition of rice husk ash (RHA) as a pozzolanic filler.

Summary: Biocomposite materials are a promising strategy for sustainable plastics, but the extraction of biopolymers often involves wasteful treatments. A new approach uses less-refined biological fillers, bypassing the energy-intensive extraction steps. We introduce biocomposite materials made by compounding polylactic acid (PLA) with spirulina, finding that the use of dissociated spirulina improves the strength and toughness of the biocomposites.
