Biophilic Design in Preschool Interiors
Modern living has made nature more and more difficult for individuals to access, but the yearning to connect with nature still exists. Children are particularly affected by this, as they have to stay indoors while separated from their parents, which is especially true for them. Biophilic design is an architectural and interior design concept that aims to bring humans closer to nature by integrating natural components into the built environment.

Biophysical Control of the Glioblastoma Immunosuppressive Microenvironment
Glioblastoma (GBM) is the most aggressive and common form of primary brain cancer with a dismal prognosis. Current GBM treatments have not improved patient survival, due to the propensity for tumor cell adaptation and immune evasion, leading to a persistent progression of the disease. In recent years, the tumor microenvironment (TME) has been identified as a critical regulator of these pro-tumorigenic changes, providing a complex array of biomolecular and biophysical signals that facilitate evasion strategies by modulating tumor cells, stromal cells, and immune populations. Efforts to unravel these complex TME interactions are necessary to improve GBM therapy. Immunotherapy is a promising treatment strategy that utilizes a patient’s own immune system for tumor eradication and has exhibited exciting results in many cancer types; however, the highly immunosuppressive interactions between the immune cell populations and the GBM TME continue to present challenges.

Bioplastics Biodegradation
Bioplastics have entered everyday life as a potential sustainable substitute for commodity plastics. The wide array of biopolymers and commercial blends available make predicting the biodegradation degree and kinetics quite a complex issue that requires specific knowledge of the multiple factors affecting the degradation process. Understanding the material-related and environment-related aspects that determine the actual biodegradation of bioplastics is necessary to harmonize their treatment with biowaste using the typical processing conditions of waste treatment plants.

Biopolymer-Based Composites from Agricultural Waste Biomass
Natural fibers are derived from a variety of flora and fauna sources and are utilized in the production of textiles and other commodities. These materials are recognized for their capacity to decompose naturally, their ability to endure over time, and their positive impact on the ecosystem. Fibers derived from agricultural waste biomass pertain to fibers procured from the residual components of crops, including but not limited to straw, stalks, leaves, and husks.

Biopolymers and Bioprinting for Dental Tissue Engineering
Dental tissues are composed of multiple tissues with complex organization, such as dentin, gingiva, periodontal ligament, and alveolar bone. These tissues have different mechanical and biological properties that are essential for their functions. Therefore, dental diseases and injuries pose significant challenges for restorative dentistry, as they require innovative strategies to regenerate damaged or missing dental tissues. Biomimetic bioconstructs that can effectively integrate with native tissues and restore their functionalities are desirable for dental tissue regeneration.

Biopolymers in Textiles
Given the significant contamination of our ecosystem caused by synthetic fibers involved in the textile industry, biomaterials derived from renewable resources or endowed with biodegradability characteristics have been proposed as a possible green solution for reducing the environmental impact of fabric production. The use of polymers derived from renewable sources (both biodegradable and non-biodegradable) would result in reduced greenhouses emissions (GHG) and fossil fuel consumption (FFC) when compared to common fossil-based, non-biodegradable polymers, the most common polyester (PET), polyamide (PA), polypropylene (PP). Although less biodegradable compared to natural-based fibers (wool, cotton), aliphatic polyester bio-based fibers are biodegraded more quickly compared to PET fibers. Furthermore, the larger moisture vapor transmission of bio-based polymers compared to PET, PA and PP materials, allows greater breathability by corresponding fabrics. Biobased fibers are also endowed with good mechanical resistance and antibacterial properties, low flammability and less smoke generation.

Biopolymers Used in Cladding
Cladding is used as the outer layer in high-rise buildings to protect the building from weather conditions and enhance its visual appeal. Its primary function is to shield structures from environmental factors such as radiant sunlight and moisture, thereby preserving their structural integrity.

Bioprinting Scaffolds for Vascular Tissues
Human organ function and physiology depend on a functional vascular system to facilitate oxygen and nutrient supply, as well as the removal of metabolic products. Ischemia is temporary reduction of blood supply that can cause physiological imbalance due to a lack of oxygen (hypoxia), nutrients, and a failure to eliminate metabolic waste products. Prolonged ischemia is associate with tissue damage and potentially necrosis. In this context, avoiding ischemia time remains critical to preventing hypoxic injury and potential damages to transplant tissues and organs. Despite substantial progress in creating three-dimensional (3D) blood vessels, fabricating a functional vascular multiscale system has remained a challenge . Many techniques have been developed to fabricate vascular networks that can mimic the complexity, the unique structures, and the functionality of human blood vessels.  Among these advancements, 3D bioprinting has become an essential tool for the fabrication of vascularized bioconstructs due to improved control over vascular growth, reproducibility, and scalability of the fabrication process.
