• Molecules in collective ecstasy
  When fluorescent dye molecules nestle perfectly together, something completely new is created: an excited state distributed over many molecules. Such collective excitations can be used in a variety...
• First synthesis and complete characterisation of Silicon with a two-dimensional structure
  Silicon, a semi-metal, bonds in its natural form with four other elements and its three-dimensional structure takes the form of a tetrahedron. For a long time, it seemed impossible to achieve the s...
• A novel microscope pins down the miracle of molecular oxygen
  Researchers at the University of Regensburg track the first step of the reaction of one single dye pigment with oxygen at unprecedented resolution. Why is it that the colours of a t-shirt fade o...
• Pathogenic fungi colonise microplastics in soils
  Representatives of numerous pathogenic fungal species are finding new habitat on microplastic particles in the soil and could thus be one of the possible causes of an increase in fungal infections....
• Synthesizing aryl sulfides from non-smelling, non-toxic compounds
  Aryl sulfide, an aromatic compound in which sulfur is attached to an aryl (a functional group derived from an aromatic ring), is found in biologically active materials effective against asthma, Alz...
• ELISA Developed for measurement of an important grass allergen
  Therapy options for allergies are increasing in number. Various therapeutic allergen products are available for allergic patients, but there is a lack of standard methods for comparing the active i...
• Smart microparticle that identifies defective parts in electrical appliances
  Repairing complex electrical appliances is time consuming and rarely cost-effective. The working group led by Prof. Dr. Karl Mandel, Professorship of Inorganic Chemistry at FAU, has now developed a...
• The mechanism that leads to unique, hollow-structured crystals having sought-after properties
  From the creators of yo-yo crystals comes the brand-new sequel - hollow crystals. When a team of scientific investigators detected an enigmatic structure never before seen in a lab, they knew they ...
• A passive perspiration biofuel cell: High energy return on investment
  A new wearable device turns the touch of a finger into a source of power for small electronics and sensors. Engineers at the University of California San Diego developed a thin, flexible strip that...
• Symbionts sans frontieres: Bacterial partners travel the world
  This pandemic year has seen us confined to our homes and restricted from travelling the world. Not so for some microscopic bacteria in the ocean: Throughout the globe, they partner up with clams fr...
• The mechanisms behind bacterial resistance to silver nanoparticles
  Antimicrobials are used to kill or slow the growth of bacteria, viruses and other microorganisms. They can be in the form of antibiotics, used to treat bodily infections, or as an additive or coati...
• Molecule layer aids chemoselective hydrogenation on solid palladium catalysts
  Chemical reactions don't always go to plan. Unwanted by-products lead to extra costs and waste resources. Selective catalysts can help, but chemists have to test out large numbers before they find ...
• New software improves data-independent acquisition proteomics
  Proteomics produces enormous amounts of data, which can be very complex to analyze and interpret. The free software platform MaxQuant has proven to be invaluable for data analysis of shotgun proteo...
• How our universe might produce organic molecules in deep space
  Laboratory astrophysicists led by Jiao He (Max Planck Institut for Astronomy) have found a new mechanism that could explain how complex organic molecules form in interstellar clouds - a key open qu...
• Microfluidics as key technology for fighting pandemics
  With international participation, this year's COMPAMED Innovation Forum was dedicated to the topic of "Microfluidics for mobile diagnostics and development of vaccines and drugs" and presented how ...
• High levels of efficacy of next-generation COVID-19 Vaccine
  Novavax, Inc., a biotechnology company developing next-generation vaccines for serious infectious diseases, today announced the publication of results from the final analysis of a pivotal Phase 3 c...
• Miniature spectrometer for the smartphone
  Recognizing fake drugs? Testing water samples ourselves? Checking the quality of air? In the future, it could be possible to do all this using a smartphone in a quick, cost-effective and straightfo...
• Synchrotrons accelerate corona research
  Synchrotron light sources were originally built to study particles. Today, they are even used in the fight against COVID-19. The projects are as diverse as the fields of the synchrotron users, who ...
• Breakthrough for tracking RNA with fluorescence
  Researchers at Chalmers University of Technology, Sweden, have succeeded in developing a method to label mRNA molecules, and thereby follow, in real time, their path through cells, using a microsco...
• New face mask prototype can detect Covid-19 infection
  Engineers at MIT and Harvard University have designed a novel face mask that can diagnose the wearer with Covid-19 within about 90 minutes. The masks are embedded with tiny, disposable sensors that...
• Plasmas as chemistry labs
  The smaller a plasma, the larger the experimental setup needed to study it. It is worth the effort, because the reaction conditions found in cubic-millimetre-sized plasmas are very much unique. ...
• New method for the production of protonated hydrogen
  Using intense pulses of laser light, members of the attoworld team at the Max Planck Institute for Quantum Optics and the Ludwig-Maximilian University have synthesized trihydrogen ions from water m...
