Disinfecting is a procedure that uses chemicals/disinfectants to kill germs on surfaces and objects. Some common disinfectants include bleach and alcohol-based solutions. Disinfectants are usually left on target surfaces and objects for a certain period to kill germs. Also, the task of sanitizing can involve either cleaning or disinfecting or both. According to the Center for Disease Control and Prevention (CDC), sanitizing refers to lowering the number of germs on the surface to a safe level. The safe level depends on public health standards or requirements at workplaces, such as healthcare facilities. Some common ways of disinfecting and sanitizing include mopping a floor using a mop with disinfectants and water, disinfectant wipes or hand sanitizers, and others.

Dicyclopentadiene is a chemical compound with the formula C10H12. It is co-produced in large quantities in the steam cracking of naphtha and gas oils to ethylene as part of the separation process of crude C5 streams. It is a colorless, waxy, flammable solid or liquid with a camphor-like odor. Dicyclopentadiene is highly flammable, with a flashpoint of 90°F/32°C and a boiling point of 338ºF/170°C. The major uses are in resins, particularly unsaturated polyester resins. As a chemical intermediate, it is used for making insecticides, hardeners, and dryers in linseed and soybean oil and in the production of ethylene propylene diene monomer (EPDM) elastomers, metallocenes, resins, varnishes, and paints.

Wood-based products are often prone to corrosion, destruction, and stains. A glossy wood coating prevents damage and increases the durability of wooden products, thus boosting their sales. It also makes wooden products desirable and aesthetically pleasing, thus luring customers into buying them. There are many wood coatings, including exterior wood coating, waterborne wood coating, radiation cure coatings, and wood finishing. Exterior wood coatings are extremely important in the furniture industry as they offer a good finishing and make furniture sturdy.

UV curable coatings are based on UV curing technology that makes use of ultraviolet light to initiate the reaction. UV-based coating formulations can be applied to a variety of substrates such as paper, wood, metal, and plastic. The technology requires very less space and lesser curing time than conventional technologies. In many cases, the amount of heat generated while curing is also less; therefore, heat-sensitive substrates can also be coated. These UV coatings come in a variety of types such as 100% solids, water-based, solvent-based, pigmented, clear, and various gloss formulations.

Silicone sealants are employed to seal objects/surfaces that may be exposed to extreme environments, weathering, temperature, or movement for a prolonged period. Sealants are effective solutions that are elastic, flexible, durable, and reliable. Hence, they can be put to application in harsh conditions, ranging from construction, space, electronics, automotive, medical, and packaging. Silicone sealants are composed of silicone as a primary ingredient. The other essential components that provide silicone sealant their inherent properties are polymers, plasticizers, active reinforcing fillers, passive non-reinforcing fillers, cross linkers, and special additives. Silicone sealants based on their specific application can be readily modified using biobased materials. Through the addition of specific additives and fillers, they can be imparted enhanced electrical/thermal conductivity, resistance to fluctuation temperatures, and optical clarity, among others.

截止目前，国家已累计开展七批药品集中带量采购。2018/11 集采序幕拉开，第一批先于“4+7”城市试点，后扩围至全国；第六批为胰岛素专项，为集采首次拓展到生物药领域；第七批于2022/06 开启，2022/07 公布中选结果，拟于2022/11起实施。历次集采对药品申报资格要求未发生实质性变化，需满足三个条件之一：1）参比制剂；2）通过一致性评价的仿制药；3）证明质量和疗效与参比制剂一致的仿制药。我国批准上市的药品中95%为仿制药，参比制剂多为国外原研药，集采药品或以第（2）（3）种仿制药为主。

Medical grade tubing is a product designed for a number of applications that enable clinicians to perform several tasks, which normally include disposable applications such as medical catheters, IV sets, irrigation, drainage, and intravenous (IV) delivery. The applications are considered for medical applications such as abrasion protection, drug delivery, bulk disposable tubing, catheters, special applications, and other applications such as arthroscopy, endoscopy, and laparoscopy.

Although the raw materials required to manufacture paints and coatings have a relatively smaller margin (approximately 5%), they are extremely important components of the global chemicals industry. The different ingredients used to manufacture paints and coatings include resins, solvents, additives, pigments, and fillers. Resins are the most widely used raw materials as they account for around 49% of the total raw materials by value, followed by pigments and fillers, additives, and solvents. Coating resins are fundamental components of coating raw materials used to formulate paints and coating materials. Also, coating resins are added in small quantities to coating materials to enhance their features during manufacturing, storage, transport, and application.

随着行业技术的革新，部分装备在高温、压强腐蚀性等苛刻环境已无法实现长期可靠服役。但新装备的研制是基础究和应用研究相互促进的过程，往往需要耗费大量的人力物力，因而装备材料端便迎来了巨大的挑战。当前许多传统材料的研发已接近理论极限，寻找综合性能优异新料成为推动高端制造业发展的关键。碳纤维具备优异力、热、电磁性能，同时还可以作为增强材料与树脂、金属陶瓷及炭基体等复合制造先进复合材料，目前已然成为高端制造业业换装首选材料。

Disposable contact lenses are single-use lenses that are removed and discarded after use. These lenses are more convenient compared with reusable contact lenses. Increasing adoption of disposable contact lenses and popularity among practitioners are some of the major factors driving the market. As of 2021, at least 2.2 billion people across the globe have near or distant vision impairment. The most common reasons for vision impairment and blindness are uncorrected refractive errors and cataracts.
