OP-FTIR spectrometerIndustrial monitoringAir quality monitoringRetroreflector arrayWe have recently completed a United States Air Force SBIR Phase II contract to develop a low-cost open-path Fourier transform infrared spectrometer; the intended application is air quality monitoring inside a hangar where ...
The chemical compositions were evaluated by combustion elemental analyzer (Elementar, vario MICRO cube), X-ray photoelectron spectroscopy (XPS, ESCALAB 250 using Al Kα radiation source), Fourier transform infrared spectrometer (FTIR, Thermo Scientific Nicolet iS20), thermogravimetric-differential thermal ...
lei Yang4, Li Zhou2, Xiangheng Xiao3, Changzhong Jiang3 & Vellaisamy A.L. Roy2 Ideal SERS substrates for sensing applications should exhibit strong signal enhancement, generate a reproducible and uniform response, and should be able to fabricate in large-scale and low-cost. ...
An X-ray diffractometer (Empyrean X-ray Diffractometer from PANalytical) was used to detect the XRD patterns of LDH before and after adsorption with Cu Kα radiation (λ = 1.5405 Å, 40 kV, 35 mA), using 2θ = 5–80◦). An FTIR spectrometer (Bruker Vertex 70) was used ...
A Nicolet iS 5 FTIR Spectrometer was used to conduct FTIR experiments. The scanning range was from 400 to 4000 cm−1, and the spectrum resolution was 4 cm−1.Data availability The authors declare that the data supporting this study's findings are available within the paper and its ...
The surface structures of the sorbents were characterized using Fourier transform infrared (FTIR) spectroscopic measurements with a Nicolet iS5 FTIR spectrometer (Thermo Fisher Scientific) equipped with a KBr/Ge beam splitter and a high-performance deuterated triglycine sulfate detector. A smart iTX-iD...

Low cost laserless FTIR spectrometer on the farm for real-time nitrous oxide soil emission measurements A low-cost Fourier transform infrared (FTIR) instrument was developed where the traditional He-Ne reference laser was replaced by a low-cost linear encoder... KH Haugholt,M Lacolle,M O'Farr...
The flexible printed electronics (e.g., wearable devices, roll-up displays, heating circuits, radio frequency identification (RFID) tags) calls for high-conductivity and low-cost materials, particularly for copper pastes. It is still a big challenge to develop reliable copper pastes for both antio...
The ionoSolv pretreatment generates a cellulose pulp by extracting hemicellulose and lignin using low-cost ionic liquids. In this study, cellulose pulp was
