Bioresorbable (or bioabsorbable) metallic glass is a type of amorphous metal, which is based on the Mg-Zn-Ca ternary system. [1] Containing only elements which already exist inside the human body, namely Mg , Zn and Ca , these amorphous alloys are a special type of biodegradable metal .
Paintballs, also simply called "paint", are spherical gelatin capsules containing primarily polyethylene glycol, other non-toxic and water-soluble substances, and dye. Paintballs are made of materials found in food items, and are edible but taste disagreeable as they tend to dry up the mouth. [ 4 ]
Unless stated otherwise, the properties of fused silica (quartz glass) and germania glass are derived from the SciGlass glass database by forming the arithmetic mean of all the experimental values from different authors (in general more than 10 independent sources for quartz glass and T g of germanium oxide glass). The list is not exhaustive.
Whether a material is biodegradable is determined by its chemical structure, not the origin of the material from which it is made. [14] Indeed, the sustainability benefits of drop-in biobased plastics occur at the beginning of the material life cycle, but still, when manufactured, their structure is identical to their fossil-based counterparts.
A paintball marker, also known as a paintball gun, paint gun, or simply marker, is an air gun used in the shooting sport of paintball, and the main piece of paintball equipment. Paintball markers use compressed gas , such as carbon dioxide (CO 2 ) or compressed air (HPA), to propel dye -filled gel capsules called paintballs through the barrel ...
Biodegradable technology is established technology with some applications in product packaging, production, and medicine. [31] The chief barrier to widespread implementation is the trade-off between biodegradability and performance. For example, lactide-based plastics are inferior packaging properties in comparison to traditional materials.
Plasticizers may be added to improve processing properties, lower the glass transition temperature, improve impact properties, and improve mechanical properties such as elastic modulus [27] Dyes may be added to give color for decorative applications, or to protect against (or filter) UV light. Fillers may be substituted to reduce cost.
The Angel paintball marker was designed by engineer John Rice, as an HPA-only marker. Despite its ubiquitous use in the sport at the time, Rice considered CO 2 a dirty gas , so the Angel used miniaturized components that could not withstand impurities in the air or the cooling effects of CO 2 .
