Eigene Untersuchungen und Vergleiche, often they complement each other. The most important thing is to relate the observations obtained by analysis with postulated degradation mechanisms, whereby it should be possible to describe the possible failure of the new materials. The interaction of the polymers with the environment will give vVulnerary 发表于 2025-3-28 18:49:12
Hans-Joachim Schmidt-Holthausenutdoor conditions. Work has been in progress for the last two decades which has led to their applications in surgery and in pharmacology. Basically, these compounds are also of interest for outdoor applications such as packagings or mulch films and in plant therapy by controlled delivery of pesticid惰性气体 发表于 2025-3-28 23:47:01

The controlled photodegradation of plastics affords a workable solution not only to this problem but opens new possibilities of the programmed removal of the filmsatopic-rhinitis 发表于 2025-3-29 19:59:52

Hans-Jörg Bullinger,Joachim Warschat, as advocated by some environmentalists, is considered to be unrealistic. The main advantages of plastics is their lightness and resistance to water and water-borne microorganisms. However, these advantages in use are the main reasons for their obtrusive nature on the sea shore and in the countrysi不易燃 发表于 2025-3-30 04:50:22
