β-butyrolactone
Over 35 years ago, researchers originally reported on the anionic ring-opening polymerization (ROP) of β-butyrolactone (BBL) into poly(β-butyrolactone) (poly(BBL)), which is an amorphous, atactic analogue of isotactic poly([R]-β-hydroxybutyrate) (PHB), a promising and widely used natural biodegradable polyester.

Zwitterionic Dental Biomaterials
Biofilms are formed on surfaces inside the oral cavity covered by the acquired pellicle and develop into a complex, dynamic, microbial environment. Oral biofilm is a causative factor of dental and periodontal diseases. Accordingly, novel materials that can resist biofilm formation have attracted significant attention. Zwitterionic polymers (ZPs) have unique features that resist protein adhesion and prevent biofilm formation while maintaining biocompatibility. Recent literature has reflected a rapid increase in the application of ZPs as coatings and additives with promising outcomes.

Zirconium and Titanium Phosphates
Zirconium and titanium phosphates are a group of laminar tetravalent metal phosphates that have attracted intensive investigation interests. Unlike zirconium phosphates, titanium phosphates can be also synthesized in another morphology, exhibiting the form of nanorods, and thus are known as nanofibrous titanium phosphates.  The different synthetic routes of zirconium and titanium phosphates and their current and prospective applications with a special mention to the their plausible applications in the field of biotechnology are discussed.

Zirconia Implant-Prosthetic Components' Tissue Response
Dental components manufactured with zirconia (ZrO2) represent a significant percentage of the implant-prosthetic market in dentistry. However, during the last few years, we have observed robust clinical and pre-clinical scientific investigations on zirconia both as a prosthetic and an implantable material. Dental devices manufactured from ZrO2 are structurally and chemically stable with biocompatibility levels allowing for safe and long-term function in the oral environment.

Yeast Particles Encapsulation Methods for Terpene Release Duration
Terpenes and essential oils are materials of great commercial use due to their broad spectra of antibacterial, antifungal, membrane permeation enhancement and antioxidant biological properties, as well as for their use as flavors and fragrances. Yeast particles (YPs) are 3–5 µm hollow and porous microspheres, a byproduct of some food-grade yeast (Saccharomyces cerevisiae) extract manufacturing processes, that have been used for the encapsulation of terpenes and essential oils with high payload loading capacity (up to 500% weight) and efficiency, providing stability and sustained-release properties.

Xylose Metabolism in Bacteria
Some wild-type and genetically modified bacteria can metabolize xylose through three different main pathways of metabolism: xylose isomerase pathway, oxidoreductase pathway, and non-phosphorylative pathway (including Weimberg and Dahms pathways). Two of the commercially interesting intermediates of these pathways are xylitol and xylonic acid, which can accumulate in the medium either through manipulation of the culture conditions or through genetic modification of the bacteria.

Wide Structural Variety and Applications of Dendrimers
Dendrimers are hyper-branched macromolecules characterized by large numbers of end-group functionalities and a compact molecular structure. They consist of a central core molecule where multiple branches emerge, giving rise to a hierarchical and well-defined architecture.

Wheat Based Film
Wheat is a grass plant of the Poaceae plants family; the scientific name of wheat plant is Triticum.  Due to its mechanical and physical properties, wheat starch, gluten, and fiber are vital in the biopolymer industry. Glycerol as a plasticizer considerably increased the elongation and water vapor permeability of wheat films. Wheat fiber developed mechanical and thermal properties as a result of various matrices; wheat gluten is water insoluble, elastic, non-toxic, and biodegradable, making it useful in biocomposite materials.
