Microplastics (MPs) are ubiquitous pollutants in the ocean, and there is a general concern about their persistence and potential effects on marine ecosystems. We still know little about the smaller size-fraction of marine MPs (MPs −3, with 88% of t

Publikováno v: EPJ Web of Conferences, Vol 215, p 08002 (2019)

Freeform optical elements are state of the art for several years to fabricate very high performance optical systems with the necessity of, e.g., strong folding in mirror system or correction of typical asymmetric aberrations in mirror systems as well

A real-time capable coherent data cache for multicores

Autor: Arthur Pyka, Sascha Uhrig, Mathias Rohde

Publikováno v: Concurrency and Computation: Practice and Experience. 26:1342-1354

In multicore systems, the concurrent access to shared data generates a bottleneck for the system performance. Cache coherence techniques have been introduced to enable fast access while preserving the data coherence, but these coherence protocols are

Direct Bonding of Glass Substrates

Autor: Andreas Tünnermann, Stefan Risse, Mathias Rohde, Gerhard Kalkowski, Ramona Eberhardt

Publikováno v: ECS Transactions. 33:349-355

We report on investigations of direct bonding of glass materials for application as optical devices and high precision mechanical stages under vacuum conditions. Thin SiO2 (fused silica) wafers of about 1mm thickness were bonded to massive SiO2 subst
