Design and Modeling of a High-Speed AFM-Scanner

A new mechanical scanner design for a high-speed atomic force microscope (AFM) is presented and discussed in terms of modeling and control. The positioning range of this scanner is 13 mum in the X- and Y-directions and 4.3 mum in the vertical direction. The lowest resonance frequency of this scanner is above 22 kHz. This paper is focused on the vertical direction of the scanner, being the crucial

Internets kollektiva minne är företagens stora framtidsutmaning

Jag ser med spänning fram emot när dagens ungdomsgeneration kommer ut på arbetsmarknaden. Ni vet, den generation som får utstå vuxensuckar på grund av fascinationen av självcentrerade selfies-porträtt och mängden ogenomtänkta bilder från vilda tonårsfester.

Robotics in rehabilitation

Robotics in rehabilitation provide considerable opportunities to improve the quality of life for physically disabled people. However, practical results limited, mainly due to the need for developing new robotics concepts where people are where they are working in separeted areas. This paper reveals some of the developments needed and presents two projects currently underway at Lund University. The

Aromatic Polymers Functionalized with Anionic and Cationic Groups for Ion Exchange Membranes

Fuel cells, redox flow batteries and some water desalination technologies such as reverse osmosis and electrodialysis require efficient ion exchange membranes to perform in an optimum way. Thus, by enhancing the properties of these membranes there is a possibility to improve this type of applications and technologies. Depending on the specific application, anion or proton exchange membranes with g
