Aqueous Redox Flow Cells Utilizing Verdazyl Cations enabled by Polybenzimidazole Membranes.

Non-aqueous organic redox flow batteries (RFB) utilizing verdazyl radicals are increasingly explored as energy storage technology. Verdazyl cations in RFBs with acidic aqueous electrolytes, however, have not been investigated yet. To advance the application in aqueous RFBs it is crucial to examine the interaction with the utilized membranes.

Benchmarking organic active materials for aqueous redox flow batteries in terms of lifetime and cost.

Flow batteries are one option for future, low-cost stationary energy storage. We present a perspective overview of the potential cost of organic active materials for aqueous flow batteries based on a comprehensive mathematical model. The battery capital costs for 38 different organic active materials, as well as the state-of-the-art vanadium system are elucidated.

Anterior Subcapsular Cataract Formation With Long-term Topical Netarsudil Treatment for Glaucoma.

Purpose: The purpose of this study was to describe anterior subcapsular cataract development in patients on long-term topical netarsudil use.

Patients And Methods: This clinical observational study summarizes a similar cataract pattern demonstrated in a series of patients from a single physician practice and a university-based outpatient clinic during their routine clinical follow-up visits from October 2020 to August 2021. All patients have been using topical netarsudil once daily for at least 15 months.

[Conception and data transfer analysis of an open-source digital image archive designed for radiology].

Purpose: Implementation of a self-designed, web-based digital image archive incorporating the existing DICOM infrastructure to assure distribution of digital pictures and reports and to optimize work flow. Assessment after three years.

Materials And Methods: Open-source software was used to guarantee highest reliability and cost effectiveness.

[Standards for safe data exchange in teleradiology exemplified by image and report distribution].

The use of telemedicine is becoming indispensable for a continuous and economical delivery of a high quality of care. However, data protection requirements have to be considered. For the selection of solutions, vendor-independent components based on standards are a prerequisite for a seamless integration into the existing, often heterogeneous, IT infrastructure.
