A tunable cohesive granular material
Ref.-No.: 0705-5158-BC
New Materials
For sieving and separation purposes porous materials with adjustable sizes and shapes of the pores as well as tunable mechanical properties are required. The existing materials such as sintered materials, open-cell foams or cemented aggregates can be made porous but they are either fragile or can collapse for large deformation. Therefore, chemically inert and damage resistant porous materials with adjustable permeability as well as mechanical and geometrical properties that can sustain large deformation ...

Anti-mouse and anti-rabbit IgG secondary VHH single domain antibodies optimized for all immuno-labeling applications
Ref.: 0707-5419-LI
New Materials
Anti-IgG secondary antibodies are major tools for the detection or immobilization of primary antibodies in approaches such as western blotting, ELISA, Co-IP and immunofluorescence. Polyclonal anti-IgG secondary antibodies are produced in animals, such as mouse, rabbit, rat, and goat and are directed against the IgG classes of these animals. Thus, the generation of such secondary antibodies requires the keeping and use of a large number of animals, which is not only costly but also a major ethical ...
Bioinspired Liquid-Superrepellent Fibrillar Dry Adhesives
Ref.-No.: 0104-5929-GÖ
New Materials
Since 2000 bioinspired fibrillar dry adhesives have been studied intensively culminating in commercial products already available on the market. Currently known fibrillar adhesives are fully wetted by oils, leading to significantly decreased adhesion and friction performance. Therefore, a high demand exists for reversible dry fibrillar adhesives that can repel oil-like liquids and adhere strongly to surfaces wetted by them.
To meet the aforementioned challenges, an extraordinary fibrillar ...

Core-shell catalyst design for improved heat management with highly exothermic reactions
Ref.-No.: 1402-5768-LC
Processes and Methods (incl. Screening)
New Materials
Prof. Kai Sundmacher and co-workers at the MPI for Dynamics of Complex Technical Systems developed a novel core-shell catalyst design with a highly active catalyst core surrounded by an inert, low-permeability shell. The new catalyst design leads to an intrinsic heat management that avoids hotspots in strongly exothermic reactions. This allows faster reactor start-up and shut-down and makes the catalysts suitable for rapid load changes in discontinuous processes.
