Hand-rim is the most favoured mode of propulsion by a large percentage of wheelchair users even though it leads to severe upper limb injuries. This novel manual wheelchair propulsion device is optimized for the musculoskeletal system of the arm.
Semiconductor nanocrystals, or quantum dots (QD), are tiny, nanometer-sized, Cd based particles with the ability to absorb light and re-emit it with well-defined colors. This is why they have become a building block of the display technology. In order to help reduce reliance on Cadmium a new generation of quantum dots ZnS(Se):Mn has been developed.
Vaccines provide long-term resistance against diseases by generating an immune response to disease antigens. Some vaccines generate a poor response or are rapidly degraded. Adjuvants (e.g alum) potentiate this response, although it is not strong enough as required for the new generation of subunit vaccines.
Bacterial spot is one of the most devastating diseases of pepper and tomato grown in warm, moist environments. A new graphene based material shows antimicrobial effects against Xanthomonas euvesicatoria, which causes bacterial spot disease on pepper plants.
The operation of under-frequency load shedding (UFLS) protection in power systems suffers from the lack of flexibility to different operating conditions. Wide-area solutions solve this issue, but at the same time have negative impact on robustness, transparency and reliability. In power-system protection, that isn’t acceptable.
The world’s first, fast and reliable testing system, which doesn’t require laboratory conditions or any specialized professionals. It allows for measurements, which last only a few seconds. The system is robust and mobile and increases customer loyalty due to certification of the quality of bitumen.
On all hands plastic recycling becomes more and more importance. But, primarily due to missing accurate sorting technologies mixed waste fractions are still incinerated or disposed. ZKS- Trenntechnik offers a new efficient plant concept based on density separation, which is able to recover post- consumer plastics especially polyolefins from these heterogeneous material streams for recycling.
