Dense non-Brownian suspension flows of hard particles display mystifying properties: As the jamming threshold is approached, the viscosity diverges, as well as a length scale that can be identified from velocity correlations. To unravel the microscopic mec ...
We present a detailed comparison of the rheology of concentrated hard and soft-sphere suspensions using a variety of techniques including large-amplitude oscillatory shear (LAOS). While the soft spheres are jammed and exhibit permanent contact, the hard-sp ...
The aim of the pharmaceutical industry is to manufacture complex therapeutic proteins or biologics to treat human diseases. The manufacture of biologics requires a significant amount of financial and infrastructure resources. For this reason, efforts are b ...
In this paper, a data-driven approach is proposed to tune fixed-order controllers for unknown stable LTI plants in a mixed-sensitivity loop-shaping framework. The method requires a single set of input-output samples and it is based on convex optimization t ...
Highly concentrated suspensions of silica particles present shear thickening properties, shifting from a low to a high viscosity state, instantly and reversibly at a critical shear rate. Their viscosity increases by up to 3 orders of magnitude, changing fr ...
Since sustainability and environmental issues rose lately, lightweighting has been the point of interest for automotive and aerospace sectors. Lightweighting reduces the fuel consumption of the vehicles and as a result of this reduces emissions. Aluminum, ...
A new method for H-infinity gain-scheduled controller design by convex optimization is proposed that uses only frequency-domain data. The method is based on loop shaping in the Nyquist diagram with constraints on the weighted infinity norm of closed-loop t ...
Gels of semi-flexible polymers, network glasses made of low valence elements, softly compressed ellipsoid particles and dense suspensions under flow are examples of floppy materials. These systems present collective motions with almost no restoring force. ...
NOVELTY - The device has a carrier (1) which is provided with micro-cavity (2) for containing medium in direct contact with the object on which the medium is to be applied. Other carrier is provided with ring to protect the medium from environment when the ...
The use of micro-algae within industrial applications, such as biofuel production, has several limitations with regard to cost and therefore sustainability. Micro-algae biomass consists of small single cells that stay in suspension making them difficult to ...
