Mouth guards and mouth pieces are widely used in many fields of applica-tions. Mouth guards can prevent or reduce injury to the teeth and gums in contact sports like American football or boxing. Furthermore mouth pieces are used in medical breathing apparatus or diving equipment. They are even utilized in dental procedures like tooth bleaching or as dental night guards. Mouth guards and mouth pieces are either produced in mass production with low costs resulting in a poor wearing comfort or they are manufactured by an expensive customized fabrication process. There is a great demand for custom-fit mouth guards and dental appliances without the need to have it formed by a dentist. Mouth guards and mouthpieces are usually made from soft or hard materials, but it would be desirable to fabricate custom-fit mouth guards which are hard enough to offer protection and soft enough to provide a high wearing comfort.<br><br> <strong>Technology</strong><br> This self-customizable mouth guard is made of a shape memory polymer (e.g. polyesterurethane). The shape memory polymer turns into the custom form, if it is heated and custom-fitted (boil-and-bite principle). But the shape memory polymer can return to its predefined form when heating them above a material-dependent transition temperature and the mouth guard can be custom fitted several times. Due to its customized form the mouth guard enables a high wearing comfort. <br><br>

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
