Kidney cancer is classified as malignant tumors originating from different renal cells with several subtypes. The cells of these subtypes can mimic a benign kidney tumor, called oncocytoma. The unequivocal differentiation is essential for planning the
adequate operative procedure (tumor removal [oncocytoma] or complete kidney resection with lymph node preparation [malignant kidney cancer]) and potential follow up (not necessary in oncocytoma).

NEG layers <i>(non-evaporating getter)</i> are able to remove the majority of gases from a high vacuum device at room temperature. In doing so, they also capture the gases released from the carrier material. After being activated, the NEG film is a clean metal surface which facilitates a high pumping speed and lower level of outgassing. Up to now, its usage has been limited due the time-consuming and complex method used for its production.

The invention allows reconstructing the shape of a droplet with the help of reflections of a light source. Hereby, the contact angle between the droplet and the substrate as well as the droplet volume and other parameters can be determined. Through a vertical view many droplets can be captured automatically and synchronously. The procedure simplifies the conventional determination of wettability parameters of new surfaces and can be applied wherever many droplets need to be captured and analyzed at the same time.

Especially infections by multi-resistant bacteria are more and more common and have developed into a major health concern in many facilities around the world. The present invention relates to a method for the preparation of a strain-adapted vaccine specific for a bacterial strain based on OMVs.

Medical implants are widely being used in orthopaedics and in modern dentistry. While significant progress has been made to improve the production of implants using the most advanced materials and technologies, there is still need for additional strategies to improve and accelerate osseointegration. The improper integration of the implant material in the living bone can impair the healing process and limit the freedom of movement thereby rendering the implant useless.

The invention provides a multilayer bio-nanocoating
to improve significantly the adhesion of osteoblasts to the implant, which is shown in Fig.2. The applied bio-nano-coating is tightly connected to the implant and at the same time ensures flexibility of the molecular layers. Further the bio-nano-coating enables the native
conformation of embedded molecules, e.g. of fibronectin. Data from animal models are available for dental applications.

In summary, the invention comprises medicinal
implants with biofunctional coating, which will greatly reduce the incidence of periimplantitis and other complications related to the insufficient adhesion of the tissue to the implant.

The presented invention describes a method for increasing the efficiency of solar cells of so-called hot carrier at more than 30% by the rapid separation of hot electrons and holes in each band prior to cooling. The object is solved by the use of a specially adapted for this purpose, a double hetero structure which has never been used for the separation of the hot carrier in a hot carrier solar cell.
