Two 'Combined Stress test with in situ measurement' setups, which allow real-time monitoring of accelerated degradation of solar cells and modules, were designed and constructed. These setups allow the simultaneous use of humidity, temperature, electrical biases, and illumination as independently controlled stress factors. The setups and various experiments executed are presented.

Whole-Mount In Situ Hybridization

2023
Whole-mount in situ hybridization (WMISH) is a common technique used for visualizing the location of expressed RNAs in embryos. In this process, synthetically produced RNA probes are first complementarily bound, or "hybridized," to the transcripts of target genes. Immunohistochemistry or fluorescence is then used to detect these RNA hybrids, revealing spatial and temporal patterns of gene expression. Unlike traditional in situ hybridization techniques, which require thin tissue sections whose...

Here, we present a protocol to synthesize two metal chalcogenides (Cu1.8S and SnSe) suitable for thermoelectrics via an ultrafast (second-range), solvent-free, and one-step mechanochemical synthesis using elemental precursors. Simultaneously, we demonstrate the monitoring of the temperature in the jar during planetary ball milling in situ by the newly developed device.
FAQs
The measurement system converts a chemical or physical change in the operating environment into a trackable signal. Depending on the monitoring goal, that signal can reflect concentration, temperature, pressure, pH, or spectroscopic response. Linking signal changes to these variables allows the reaction or material to be followed as it evolves, rather than evaluated only after completion.
Time-resolved measurements distinguish gradual changes from abrupt transitions. In a chemical reaction, the resulting signal pattern can expose kinetic behavior, indicate formation of intermediates, and help identify an endpoint. Repeated observations are useful when continuous tracking is not required, while continuous data provide a fuller record of changing conditions and can reveal departures from expected behavior.
Probe compatibility is central because the measurement must function within the reaction or process environment while producing a signal relevant to the variable of interest. The selected system therefore needs to match the condition being tracked and the material or reaction being observed. A suitable match improves interpretation of changing data and supports recognition of unexpected process behavior.
A practical workflow begins by deciding which chemical or operating variables matter to the process. Compatible probes or measurement systems are then positioned in the reaction environment, and signals are collected continuously or at repeated intervals. The resulting time series can be examined for kinetics, intermediate formation, endpoint behavior, or deviations from the expected course.
Chemists choose it when the behavior of a reaction, process, or material changes over time and final measurements would not capture that history. Time-resolved observations can guide process optimization, support quality control, and improve interpretation of dynamic chemical systems. They are also useful for identifying when actual behavior departs from the expected course.
During scale-up, conditions can evolve in ways that are difficult to understand from an endpoint alone. Monitoring variables such as temperature, pressure, pH, concentration, or spectroscopic response supplies a continuing record of the process. That record can reveal deviations, support safer scale-up, and provide evidence for evaluating whether the enlarged process behaves as expected.
