  • Steel – the All-Rounder That Has to Pass Many Tests

    Steel is a real all-rounder. However, each application requires a specifi c sort of steel grade. Without steel there would be no Olympic stadiums, wind energy plants, bridges, skyscrapers, trains, planes, cars, razor blades or knives for medical and home use – at least, not of the quality and design we know today. Buderus Edelstahl GmbH in Wetzlar, Germany is one of the world’s top producers of special steel.

  • Precision That Saves Eyesight

    Retina surgery demands experienced surgeons and precision technology. In vitreoretinal surgery, the surgeon operates with microscissors and forceps that are less than a millimeter thick. The Swiss company Alcon Grieshaber is one of the world’s leading specialists in handheld instruments for minimally invasive eye surgery.

  • Restoring Former Glory with Cotton Buds and a Microscope – The Princely Collections of Liechtenstein

    On her way to work, Ruth Klebel is often approached by tourists asking for the times of guided tours. She always gives the same answer before disappearing behind the wide automatic gate: “I’m afraid there aren’t any, this is private property.” As a restorer of the collections of the Prince of Liechtenstein, Klebel is one of the very few people who regularly come and go at Vaduz Castle without actually living here.

  • Cochlea Implants for the Deaf and Severely Hard of Hearing

    People who can’t hear are outsiders, cut off from normal conversation. Children born into a silent world never learn to talk. Adults who lose their hearing due to age, accident or illness are no longer able to participate in social life as they did before and are moreover often branded as slow-witted. Prof. Dr. med. Jan Maurer, Senior Consultant of the ENT clinic and Medical Director of the Catholic Hospital of Koblenz, Germany, has specialised, among other things, in special hearing implants such as the cochlea implant, and post-implantation rehabilitative therapy.

  • The Mitochondrial Hypothesis of Ageing

    Why do we grow old? Research scientists have been looking for an answer to this question for many years – particularly against the background of the increase in neurodegenerative diseases among older people such as Morbus Parkinson.

  • Just What the Surgeon Wants

    We’ve all experienced an everyday product at some time that had great technology and a stylish design but was totally impractical to use. A designer coffee pot that spills its contents all round the cup or a mobile phone with such tiny keys that you can’t help pressing two at once. If instruments for medical professionals were designed with so little regard for practical application, they’d have no chance of surviving on the market.

  • Seeing Without a Haze – Trends in Cataract Surgery

    Cataract surgery has been practised for centuries and is one of the most common operations performed worldwide today. Ultra modern surgical techniques with tiny incisions and high-quality prosthetic lenses make the operation extremely safe and yield excellent results. Nevertheless, cataract surgery is being perfected all the time.

  • Fluorescence-guided Resection of Malignant Glioma – Only Red-fluorescing Areas Excised

    For resection of brain tumours in particular, neurosurgeons are faced with the same dilemma time and again: how to remove the tumour completely without ­destroying neurological functions. Nowadays, surgeons harness the possibilities of intraoperative fluorescence technology for exact and full excision of tumour tissue so that the patient’s quality of life can be saved or even enhanced.

  • Steel – It All Depends on What's Really Inside

    Steel, an alloy of iron and carbon, is both stable and elastic, extremely resistant, and a permanent item in our everyday life. Today there are over 2,500 standard steel types, with new grades and applications emerging all the time. Each steel type is specially made for its purpose. It is subject to stringent quality standards to ensure that it optimally withstands the specific loads.

  • Observing Life’s Nanostructures with STED

    The secrets of life and the causes of many diseases can only be fully explained if we understand the functions of the smallest components of organisms. Using the super high resolution STED microscope, research scientists are now able to observe cellular proteins and molecular structures measuring only a few nanometres.

  • Research for the Optimal Structure

    To see how liquids can be made to flow, without being directly heated or touched, you only have to watch a raw egg explode in a microwave oven. Electromagnetic forces can even melt metal at hotter than 1000 °C. In the Magnetohydrodynamics study group at the Research Centre Dresden-Rossendorf (FZD) these complex interactions between electrically conductive liquids and magnetic fields are used to control the flow and solidification processes of liquid metal alloys.
