How will the world feed 10 billion people by 2050 with no new land for agriculture? Greg Blackman speaks to machine builder Bühler about how optical sensing can maximise yield in grain processing
New methods and instruments are building on impressive investigative capabilities, finds Andy Extance
Controlling the quality and yield of crops will be crucial elements of increased food production. Growing crops in greenhouses and vertical farms (greenhouse factories) will allow us to better control the process of growing food and, in the case of vertical farms, move food production closer to the consumer (vertical farms can be integrated into existing structures such as warehouses). In greenhouses, LEDs are a popular lighting option to provide the spectral energy to crops for photosynthesis and other growth processes.
This whitepaper will explore how optical sensing is used for real-time monitoring of LED greenhouse lighting, and how this can be used to manage colour and power output.
This whitepaper details the use of differential optical absorption spectroscopy (DOAS) for monitoring complex emission spectra easily and cost-effectively
An introduction to the theory of polarised Raman spectroscopy and exploring the wealth of sample information that can be obtained using this technique.
Photonic sensing and spectroscopy enable faster, more precise identification of tumours, finds Andy Extance
Spectroelectrochemistry is an extremely valuable tool to study any mechanism that involves an electron transfer. By combining the best of both the electrochemistry and spectroscopy worlds, it allows researchers to probe a range of reactions and extract valuable information that each technique could not achieve on its own.
Multi-line lasers are an attractive alternative to laser combiners to simplify fluorescence-based imaging instrumentation. Furthermore, they help commercialise new, cutting-edge imaging systems for clinical use. This white paper explores the advantages of a permanently aligned multi-line laser, giving examples of how such a laser is used in microscopes developed at Julius-Maximilian-University of Würzburg and the University of Washington.
The technique uses a nanostructure that ‘traps’ molecules from the air and amplifies the Raman signal
Photocatalysis is the rate increase of a chemical reaction by light, often in the presence of a catalyst that starts the reaction upon irradiation. Photocatalysts are typically semiconducting metal oxides which are employed as particles in solution. Discover how Edinburgh Instruments LP980 Spectrometer was used in this application note.
