Influence of Microplastics on the Growth and the Intestinal Microbiota Composition of Brine Shrimp
Frontiers in Microbiology, 2021 Microplastics (MPs) are ubiquitous in the aquatic environment and can be frequently ingested by zooplankton, leading to various effects. Brine shrimp (Artemia parthenogenetica) has an important role in the energy flow through trophic levels in different ...

The Living ROMP of trans-Cyclooctene [PDF]
, 2009 The living ring-opening metathesis polymerization (ROMP) of trans-cyclooctene (tCO) was investigated. ROMP of tCO in the presence of PPh_3 in THF leads to the formation of narrowly dispersed polycyclooctene (PCO).

Wear Tests of a Potential Biolubricant for Orthopedic Biopolymers [PDF]
, 2015 Most wear testing of orthopedic implant materials is undertaken with dilute bovine serum used as the lubricant. However, dilute bovine serum is different to the synovial fluid in which natural and artificial joints must operate. As part of a search for a
