Schneider, Mike (author), Couzinié, Jean Philippe (author), Shalabi, Amin (author), Ibrahimkhel, Farhad (author), Ferrari, A. (author), Körmann, F.H.W. (author), Laplanche, Guillaume (author)

This work aims to predict the microstructure of recrystallized medium and high-entropy alloys (MEAs and HEAs) with a face-centered cubic structure, in particular the density of annealing twins and their thickness. Eight MEAs and five HEAs from the Cr-Mn-Fe-Co-Ni system are considered, which have been cast, homogenized, cold-worked and...

Dissolution and Recrystallization Behavior of Li₃PS₄ in Different Organic Solvents with a Focus on N-Methylformamide

Wissel, Kerstin (author), Riegger, Luise M. (author), Schneider, Christian (author), Waidha, Aamir I. (author), Famprikis, T. (author), Ikeda, Yuji (author), Grabowski, Blazej (author), Dinnebier, Robert E. (author), Lotsch, Bettina V. (author), Janek, Jürgen (author), Ensinger, Wolfgang (author), Clemens, Oliver (author)

Solid-state batteries can be built based on thiophosphate electrolytes such as β-Li₃PS₄. For the preparation of these solid electrolytes, various solvent-based routes have been reported. For recycling of end-of-life solid-state batteries based on such thiophosphates, we consider the development of dissolution and...

Effect of the Graphene Quantum Dot Content on the Thermal, Dynamic-Mechanical, and Morphological Properties of Epoxy Resin

Schneider, Bárbara (author), Ornaghi Jr., Heitor Luiz (author), Monticeli, F.M. (author), Romanzini, Daiane (author)

Different amounts of graphene quantum dots (CQDs) (0, 1, 2.5, and 5 wt%) were incorporated into an epoxy matrix. The thermal conductivity, density, morphology, and dynamic mechanical thermal (DMTA) properties were reused from the study of Seibert et al.. The Pearson plot showed a high correlation between mass loading, thermal conductivity, and...

Enhanced sulfur in the upper troposphere and lower stratosphere in spring 2020

Tomsche, Laura (author), Marsing, Andreas (author), Jurkat-Witschas, Tina (author), Lucke, J.R. (author), Kaufmann, Stefan (author), Kaiser, Katharina (author), Schneider, Johannes (author), Scheibe, Monika (author), Schlager, Hans (author)

Sulfur compounds in the upper troposphere and lower stratosphere (UTLS) impact the atmosphere radiation budget, either directly as particles or indirectly as precursor gas for new particle formation. In situ measurements in the UTLS are rare but are important to better understand the impact of the sulfur budget on climate. The BLUESKY mission...

Empirical analysis of cycling distances in three of Europe’s most bicycle-friendly regions within an accessibility framework

Schneider, F. (author), Jensen, Anders Fjendbo (author), Daamen, W. (author), Hoogendoorn, S.P. (author)

In this paper, we study observed cycling distances within an accessibility framework, using data from the Netherlands, the Copenhagen Metropolitan Area and the Freiburg Region. As a scope, we look at outbound trips in home-based tours which include a single destination. We relate these observed cycling distances to a rich set of explanatory...

During spring 2020, the COVID-19 pandemic caused massive reductions in emissions from industry and ground and airborne transportation. To explore the resulting atmospheric composition changes, we conducted the BLUESKY campaign with two research aircraft and measured trace gases, aerosols, and cloud properties from the boundary layer to the...

The clamp bender: a new testing equipment for thin glass

Zaccaria, Marco (author), Peters, Timon (author), Ebert, Jan (author), Lucca, Nerio (author), Schneider, Jens (author), Louter, P.C. (author)

The bending strength of flat glass panels including the effects of their edges, is commonly determined by means of the four-point bending test method. This is an established and reliable method. However, when testing glass thinner than 3 mm, large deformation may occur. This means that the calculated stresses might not correspond to the...

The need for renewable bio-based materials that could replace well-established synthetic composite materials is rapidly growing. For example, bio-based materials are increasingly used in applications where a lightweight design should be combined with sustainability and recyclability. However, it is often very challenging to directly transfer...

Existing challenges in surgical education (See one, do one, teach one) as well as the Covid-19 pandemic make it necessary to develop new ways for surgical training. This is also crucial for the dissemination of new technological developments. As today's live transmissions of surgeries to remote locations always come with high information loss...

Trip chaining of bicycle and car commuters: An empirical analysis of detours to secondary activities

Schneider, F. (author), Daamen, W. (author), Hoogendoorn, S.P. (author)

A largely overlooked mode choice factor of cycling is the mode-dependent capability of visiting several activity locations within a trip chain. Due to the bicycle’s limited reach in comparison to the car, this capability can be increased by urban environments that facilitate trip chaining by bicycle. In the present paper, we empirically study...

Scheduling surgery groups considering multiple downstream resources

Schneider, A.J. Thomas (author), van Essen, J.T. (author), Carlier, Mijke (author), Hans, Erwin W. (author)

Surgery groups are clustered surgery procedure types that share comparable characteristics (e.g. expected duration). Scheduling OR blocks leaves many options for operational surgery scheduling and this increases the variation in usage of both the OR and downstream beds. Therefore, we schedule surgery groups to reduce the options for...

Trip chain complexity: a comparison among latent classes of daily mobility patterns

Schneider, F. (author), Ton, D. (author), Zomer, L. (author), Daamen, W. (author), Duives, D.C. (author), Hoogendoorn-Lanser, S. (author), Hoogendoorn, S.P. (author)

This paper studies the relationship between trip chain complexity and daily travel behaviour of travellers. While trip chain complexity is conventionally investigated between travel modes, our scope is the more aggregated level of a person’s activity-travel pattern. Using data from the Netherlands Mobility Panel, a latent class cluster...

Transport safety and human factors in the era of automation: What can transport modes learn from each other?

Papadimitriou, E. (author), Schneider, Chantal (author), Aguinaga Tello, Juan (author), Damen, Wouter (author), Lomba Vrouenraets, Max (author), ten Broeke, Annebel (author)

One of the main aims of introducing automation in transport is to improve safety by reducing or eliminating human errors; it is often argued however that this may induce new types of errors. There is different level of maturity with automation in different transport modes (road, aviation, maritime and rail), however no systematic research has...

Schneider, Lisa K. (author), Flynn, Kevin J. (author), Herman, P.M.J. (author), Troost, Tineke A. (author), Stolte, Willem (author)

While traditional microplankton community assessments focus primarily on phytoplankton and protozooplankton, the last decade has witnessed a growing recognition of photo-phago mixotrophy (performed by mixoplankton) as an important nutritional route among plankton. However, the trophic classification of plankton and subsequent analysis of the...
