Hydrogen production from water splitting using renewable electric energy is an interesting topic towards the carbon neutral future. Single atom catalysts (SACs) have emerged as a new frontier in field of catalysis such hydrogen evolution reaction (HER), owing to their intriguing properties like high activity and excellent chemical selectivity. The catalytic active moiety often comprised single ...

Designing highly efficient and low-cost electrocatalysts is of great importance in the fields energy conversion storage. We report on facile synthesis a single atom (SA) iron catalyst via pyrolysis functionalized mesophase pitch. Monomers naphthalene indole underwent polymerization presence chloride, which afterwards served as pore-forming agent source for resulting catalyst. The SA-Fe@NC has w...

Running user tests for groupware requires tracking the progress of multiple users performing co-dependent tasks, while facilitating and observing their coordinated actions. This requirement negatively impacts main objective testing, which is detecting usability flaws. User testing becomes more challenging when run remotely. Even if there are tools remote that can get job done a single user, the...

The article presents an analysis of priority solutions for trams at a selected sequence intersections in Warsaw (Poland). An the literature has shown topicality this issue. A computer simulation model coordinated was constructed. Three test scenarios were designed: existing control system, new fixed-time and adaptive system with active priority. In process, detailed travel characteristics other...

In nature, quorum sensing is one of the mechanisms bacterial populations use to communicate with their own species or across coordinate behaviours. For last 20 years, synthetic biologists have recognised remarkable properties build genetic circuits responsive population density. This has led progress in designing dynamic, coordinated and sometimes multicellular systems for bioproduction metabol...

The Wizard of Oz method is an increasingly common practice in HCI and CSCW studies as part iterative design processes for interactive systems. Instead designing a fully-fledged system, the 'technical work' key system components completed by human operators yet presented to study participants if computed machine. However, little known about how are interactionally collaboratively achieved situ r...

sepiolite deposits have been recently discovered in northeastern iran. however, there is still little information about its physicochemical and mineralogical characteristics. therefore, the collapse of the sepiolite (with sizes of < 63 μm) structure induced by temperature elevation in an electric furnace at 350, 550, and 850 °c for 4 hours was studied using x-ray diffraction (xrd) in combinatio...
