Electrochemical dark-field microscopy can visualize and help investigate the reactions of individual nanoparticles
A combination of dark-field microscopy and electrochemistry can make individual nanoparticles in a liquid medium visible. The technique is suited to determine the activity of catalysts during their use.
A fundamental change in the International System of Units
The 20th of May 2019 is a special day. From that day on, the old definitions of what a kilogram, a mole, an ampere and a kelvin represent, are history. The future of the International System of Units will see natural constants play the star roles.
The new definition of the SI base unit of mass and its significance to the weighing world
For about 200 years, any mass given in kilograms, grams and micrograms referred to a defined artifact accessible in only a single location on earth. A small metal cylinder had represented one kilogram since the metric system was introduced in France. Its successor became world famous as the ...
Determining the basis for the redefinition of the units kilogram and mole
Since the 20th of May 2019, the mass unit kilogram is no longer defined by the international kilogram prototype but by the numerical value of the Planck constant, the most important fundamental constant in quantum physics. For this definition, the Planck constant needed to be measured with the ...
Microorganisms use impressive strategies for dealing with uncertainty
Bacteria are true survivors. In the course of evolution, they have developed numerous strategies to adapt to rapidly changing, uncertain environmental conditions. Their metabolism is much more sophisticated than that of human beings. Within minutes they can regulate their gene expression and, if ...
Multi-omics approach opens up new insights into the microbiome and mammalian lipid synthesis
Nature provides an enormous diversity of lipid molecules that originate from various pathways. Fatty acids are key modules for various lipids, including cell membrane lipids such as phospholipids or triacylglycerols, which are the major components of lipid droplets. Excess lipids or defects in ...
Modeling the interaction of dietary ingredients with proteins
Molecular modeling, the modeling of molecular interactions, has become established over the past decades as a standard method in the development of pharmaceuticals. At the Institute for Nutritional Sciences of the University of Potsdam, molecular modeling methods are used in interdisciplinary ...
A novel microspectroscopic method allows sugar mapping across the plant tissue
Quantitative mapping of metabolite distribution has widespread applications in medicine and biology, but has remained a key analytical challenge. A novel method for sugar imag-ing in plants based on the principles of infrared spectroscopy, which was developed at the IPK-Gatersleben, allows the ...
An emerging technology to comprehensively describe entire lipid profiles
Progress in research is – to a large extent – driven by technological and analytical advance-ments. This is particularly true for the field of lipid research in the biomedical field, which was hampered for decades by the limited availability of analytical tools to address the enormous complexity ...
Optimizing the usability of measurement instruments in centralized lab software systems
Easy access and navigation of historical measurement data stored in central laboratory software systems is important to support the documentation and, in particular, the traceability of measurement results. For some instruments it is also useful to grant users access to past measurement data.
q&more – the networking platform for quality excellence in lab and process
The q&more concept is to increase the visibility of recent research and innovative solutions, and support the exchange of knowledge. In the broad spectrum of subjects covered, the focus is on achieving maximum quality in highly innovative sectors. As a modern knowledge platform, q&more offers market participants one-of-a-kind networking opportunities. Cutting-edge research is presented by authors of international repute. Attractively presented in a high-quality context, and published in German and English, the original articles introduce new concepts and highlight unconventional solution strategies.
