Fluorescent thermometers with near-infrared (NIR) emission play an important role in visualizing the intracellular temperature with high resolution and investigating the cellular functions and biochemical activities. Herein, we designed and synthesized a donor--acceptor luminogen, 2-([1,1'-biphenyl]-4-yl)-3-(4-((E)-4-(diphenylamino)styryl) phenyl) fumaronitrile (TBB) by Suzuki coupling reaction. TBB exhibited twisted intramolecular charge transfer-based NIR emission, aggregation-induced emission, and temperature-sensitive emission features. A ratiometric fluorescent thermometer was constructed by encapsulating thermosensitive NIR fluorophore TBB and Rhodamine 110 dye into an amphiphilic polymer matrix F127 to form TBB&R110@F127 nanoparticles (TRF NPs). TRF NPs showed a good temperature sensitivity of 2.37%C-1, wide temperature response ranges from 25 to 65 C, and excellent temperature-sensitive emission reversibility. Intracellular thermometry experiments indicated that TRF NPs could monitor the cellular temperature change from 25 to 53 C for Hep-G2 cells under the photothermal therapy agent heating process, indicating the considerable potential applications of TRF NPs in the biological thermometry field.

McCalla weaves broadcasts and recordings from these journalists into her songs, allowing these speakers to tell their own stories of the risks they took to be the voice of democracy in Haiti. The songs on Breaking the Thermometer glide easily from English to French to Kreyl, implicitly acknowledging the way that language creates identity and is bound to political contexts.

Scientists use thermometers to measure things like the temperature of a liquid in an experiment. Just like with beakers and bunsen burners, thermometers are a tool scientists use to make sure they are controlling every part of their experiment.

A lens-free irradiation thermometer (LF-IRRT) designed for laboratory applications, with 1.55 \upmu m center wavelength based on the InGaAs detector, and a temperature range from 300 C to 1000 C, has been developed at NIM of China. The thermometer has no imaging optics for collecting the radiation, for which a major benefit is improved stability compared to other radiation thermometers. This paper introduces the measurement principle, the structure of the LF-IRRT, the multiple-point calibration method, and the stability and expanded uncertainty of the thermometer. The stability of the LF-IRRT is better than 0.070 C at temperatures from 300 C to 1000 C over a period of 1 month. The expanded uncertainty is less than 0.20 C for temperatures between 300 C and 1000 C. The size-of-source effect of the LF-IRRT is 0.6 % from the source diameter range from 10 mm to 65 mm.

The Solar Concentrator project, which seeks to improve upon an initial design by Optics Prof. Wayne Knox, involves both optical and mechanical engineering seniors. During the experiment above on the rooftop of Wilmot Building Jacob Blacksberg of MechE and Daniel Morgen and Michael Dupuis of Optics aim the concentrator, while Reid and Bryan Maas of Optics write down readings and observe. Henry Pablo of MechE aims an infrared thermometer and Fifi Song of Optics aims a thermal camera to document how quickly the concentrator heats its target. Michal Adar of MechE, seated, times the observations.

Thirty healthy students were selected and given reinforcing of mild moxibustion on the left Neiguan (PC 6) and reducing on the right Neiguan (PC 6) respectively. Temperature of the acupoint skin surface and the temperature-time curve were recorded by a digital thermometer.

Neutral beam injection (NBI) is one of the heating methods in tokamaks. In the process of injection, the neutral particles will not be absolutely absorbed by plasma. The unabsorbed neutral particles penetrate plasma and are shot at inner wall tiles. It will cause the temperature increases of armor tiles that are placed opposite the NBI injection windows. In order to ensure that the armor tiles work during a safe interval, the data acquisition and protection system of infrared thermometer has been developed. The system achieves the functions of isolated transmission, remote monitoring, and fast protection. The response time of data acquisition and protection system is less than 5 , and the transmission rate of the system is 5 kHz. The quick response and stability of the data acquisition and protection system have been confirmed in practice. ff782bc1db
