  2. 1. Vibrational energy harvesting for sensors in vehicles

    Author : Johan Bjurström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; piezoelectric; anti-resonance; electromagnetic induction; prescribed displacement; low frequency; nonlinear dynamics; small amplitude excitation; automotive safety; vibration energy harvesting; unified modeling;

    Abstract : The miniaturization of semiconductor technology and reduction in power requirements have begun to enable wireless self-sufficient devices, powered by ambient energy. To date the primary application lies in generating and transmitting sensory data. READ MORE

  4. 2. Interfaces In Hydraulic Pressure Energy Harvesters

    Author : Jesus Javier Lechuga Aranda; Bengt Oelmann; Sebastian Bader; Olfa Kanoun; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The fourth industrial revolution is here and with it a tidal wave of challenges for its prosperous implementation. One of the greatest challenges frustrating the development of the internet of things, and hence the next industrial revolution, is the powering of wireless sensors, as these depend on batteries with a limited lifetime.

  5. 3. The molecular mechanisms behind perception and signal transduction of UV-B irradiation in Arabidopsis thaliana

    Author : Irina Kalbina; Åke Strid; Lars-Gunnar Franzén; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Action spectroscopy; Arabidopsis; gene expression; reverse genetics; signal transduction; UV-B irradiation.; Biochemistry; Biokemi; Biochemistry; Biokemi;

    Abstract : Elevation of UV-B radiation (280-315 nm), occurring as a result of depletion of the stratospheric ozone, causes a number of physiological and biochemical changes in plants. Damage to the photosynthetic apparatus (including the bleaching of the pigments which trap the sun's energy), to the processes of cell division and growth regulation, and to the composition and replication of genetic material are just some of these changes.

  6. 4. Membrane Interactions of Arginine-Rich Peptides for the Intracellular Delivery of Gene-Targeted Drugs

    Author : Per Thoren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cellular uptake; translocation; protein transduction; circular dichroism; drug delivery; liposomes; resonance energy transfer; PNA; antigene; antisense;

    Abstract : A major obstacle for the therapeutic use of e.g. oligonucleotides is their inherently poor cellular uptake. A recently discovered class of peptides, denoted cell-penetrating peptides, has been shown to traverse cell membranes, even when conjugated to oligonucleotides or even full-length proteins.

  7. 5. Energy Harvesting for Smart-Internet-Connected Bearings

    Author : Fredrik Häggström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : With the number of interconnected devices, many of which being wireless, exceeding the human population, there is a need to power resource-constrained devices through means other than disposable batteries. Harvesting ambient energy from the vicinity of the device is one solution. READ MORE
