The transitional forms offer a deeper insight into material symmetries and their unexpected behaviour could lead to improved design of telecoms components. https://www.laboratory-journal.com/news/scientific-news/chiral-nanostructures Fri, 01 Jun 2018 10:11:00 +0000 Chip-Based Nanoscopy in HD Quality https://www.laboratory-journal.com/science/chemistry-physics/chip-based-nanoscopy-hd-quality A waveguide chip that enables optical super-resolution microscopy (“nanoscopy”) on conventional microscopes with a resolution better than 50 nm has been developed by physicists in Germany and Norway [1]. The new technique is easy to use and does not rely on complex and expensive microscopes. Furthermore, the mass-producible waveguide chip offers a much larger field-of-view as compared to current techniques. This has the great potential to open up optical super-resolution microscopy to many more people with even new applications. https://www.laboratory-journal.com/science/chemistry-physics/chip-based-nanoscopy-hd-quality Thu, 31 May 2018 12:52:00 +0000 Fighting the Doppler Broadening https://www.laboratory-journal.com/science/chemistry-physics/fighting-doppler-broadening The central idea of spectroscopy is to shine a light with variable wavelength on matter and to observe the output spectra. If the light is in resonance with a transition from one quantum state to another, strong absorption will occur. By analyzing the position of absorption peaks, one can determine the structure of an atom or molecule and how it moves. A Key Issue of Spectroscopy https://www.laboratory-journal.com/science/chemistry-physics/fighting-doppler-broadening Thu, 31 May 2018 08:30:00 +0000 Improving Superconducting Qubits https://www.laboratory-journal.com/science/information-technology-it/improving-superconducting-qubits The idea of a quantum computer can be traced back to Feynman’s talk at the 1981 conference on “The physics of quantum computation”: he recognized that simulation of nature should be quantum mechanical, “a wonderful problem, because it doesn’t look so easy” [1].  Indeed, building a quantum computer is not easy: it requires the so-called DiVincenzo criteria to be met [2]. In particular, the lifetime of a quantum bit (qubit) should be long enough, so that errors can be corrected and a useful computation performed. https://www.laboratory-journal.com/science/information-technology-it/improving-superconducting-qubits Thu, 31 May 2018 07:15:00 +0000 Stable Isotope Fingerprinting of Amino Acids https://www.laboratory-journal.com/science/food/stable-isotope-fingerprinting-amino-acids In a world where food production is becoming more globalized and industrialized, consumers are increasingly concerned about food safety, traceability, and sustainability. This is particularly true for fish and seafood products because more than half of the world’s products now come from aquaculture. To reduce costs and impact on wild fish stocks, carnivorous fish such as salmon and trout are increasingly fed alternatives to fishmeal such as plant- and insect-based diets. https://www.laboratory-journal.com/science/food/stable-isotope-fingerprinting-amino-acids Wed, 30 May 2018 09:00:00 +0000 Virtual Conference: Analytical Techniques for Advanced Materials https://www.laboratory-journal.com/news/scientific-news/virtual-conference-analytical-techniques-advanced-materials For a 2nd year material science researchers from around the globe gathered for an innovative online experience where we explored the latest cutting edge analytical solutions used to enable the development of new and advanced materials. https://www.laboratory-journal.com/news/scientific-news/virtual-conference-analytical-techniques-advanced-materials Wed, 30 May 2018 08:02:00 +0000 Non-Contact Measuring of Tiniest Currents https://www.laboratory-journal.com/science/material-science/non-contact-measuring-tiniest-currents Intensities of beam currents in particle accelerators or storage rings need to be measureable. Numerous measurement devices to determine the number of agitated electrically charged particles exist for this purpose. A large problem arises if the following is required: https://www.laboratory-journal.com/science/material-science/non-contact-measuring-tiniest-currents Wed, 30 May 2018 06:50:00 +0000 Read & Win: Direct Analysis in Real Time Mass Spectrometry https://www.laboratory-journal.com/science/literature/read-win-direct-analysis-real-time-mass-spectrometry Direct Analysis in Real Time (DART) is an atmospheric pressure ionization method. Invented in 2005, it has been evolving very fast in recent years. It is operated under ambient conditions and can be used to ionize gases, liquids, and solids. The resulting ions are analyzed in a mass spectrometer: Mass determination enables structure elucidation. Unlike most other ionization methods, DART does not require laborious sample preparation, as ionization takes place directly on the sample surface. https://www.laboratory-journal.com/science/literature/read-win-direct-analysis-real-time-mass-spectrometry Tue, 29 May 2018 12:23:00 +0000 I Think I Have Seen the Future … https://www.laboratory-journal.com/news/market-reports/i-think-i-have-seen-future During this year’s analytica fair in Munich, I had the opportunity to see how the developers at Gilson plan to add connectivity to the bench in the lab. There are quite a few companies developing solutions, but this was the most complete concept I have seen so far. https://www.laboratory-journal.com/news/market-reports/i-think-i-have-seen-future Tue, 29 May 2018 12:05:00 +0000 Miniaturized HPLC Systems https://www.laboratory-journal.com/science/chemistry-physics/miniaturized-hplc-systems In the academic environment, micro-LC played a major role in the early commercialization of HPLC systems in the 1960s. Although the technical requirements were significantly worse than today, many university research groups have succeeded in successfully demonstrating the much-cited advantages of miniaturized HPLC systems in the form of proof-of-concept studies. https://www.laboratory-journal.com/science/chemistry-physics/miniaturized-hplc-systems Tue, 29 May 2018 10:10:00 +0000 Is Variable Production “Science Fiction”? https://www.laboratory-journal.com/news/market-reports/variable-production-science-fiction In “Star Trek - Next Generation”, nearly all items for everyday consumption such as food and beverages are produced by a single device, the replicator. For us today, this is science fiction. However, many devices of everyday life today are already more advanced than those that were still science fiction in the first Star Trek series. When we remember Captain Kirk’s “communicator” and compare it to our smartphones we can only smile. https://www.laboratory-journal.com/news/market-reports/variable-production-science-fiction Tue, 29 May 2018 08:10:00 +0000 DIY Low-Budget Smartphone Photometer https://www.laboratory-journal.com/science/chemistry-physics/diy-low-budget-smartphone-photometer A LED photo sensor, designed as a kit and assembled more than 100 times by school groups, has been fundamentally revised. In the new version, the light detector is now a component of digital electronics and is connected to a Wifi- (WLAN-) enabled microprocessor, which transmits its data to a smartphone. At approx. 30 €, the price of the required components is quite moderate, and instead of the previously required multimeter, now any commercially available smartphone can be used. https://www.laboratory-journal.com/science/chemistry-physics/diy-low-budget-smartphone-photometer Tue, 29 May 2018 08:10:00 +0000 Polymer Analysis and Microplastics in the Environment https://www.laboratory-journal.com/science/chemistry-physics/polymer-analysis-and-microplastics-environment The abbreviation TED-GC-MS describes a two-step method for volatile diagnostics originating from polymers at high temperatures.
