Ultrasensitive Surface-Enhanced Raman Scattering Sensor of Gaseous Aldehydes as Biomarkers of Lung Cancer on Dendritic Ag Nanocrystals

13-Jan-2017 | Zhen Zhang; Wei Yu; Jing Wang; Dan Luo; Xuezhi Qiao; Xiaoyun Qin; Tie Wang, Analytical Chemistry, 2017

Surface-enhanced Raman scattering (SERS) is expected as a technique that even theoretically detected chemicals at the single molecule level by surface plasmon phenomena of noble metal nanostructures. Insensitivity of detecting Raman weak-intensity molecules and low adsorptivity of gaseous ...


Sensors, Vol. 16, Pages 1820: A Photoactivated Gas Detector for Toluene Sensing at Room Temperature Based on New Coral-Like ZnO Nanostructure Arrays

31-Oct-2016 | Yeh, Li-Ko ; Luo, Jie-Chun ; Chen, Min-Chun ; Wu, Chih-Hung ; Chen, Jian-Zhang ; Cheng, I-Chun ; Hsu, Cheng-Che ; Ti ..., Sensors, 2016

A photoactivated gas detector operated at room temperature was microfabricated using a simple hydrothermal method. We report that the photoactivated gas detector can detect toluene using a UV illumination of 2 μW/cm2. By ultraviolet (UV) illumination, gas detectors sense toluene at room ...


Silver Ion Polyelectrolyte Container as a Sensitive Quartz Crystal Microbalance Gas Detector

20-Oct-2016 | Yosuke Tsuge; Yukari Moriyama; Yuki Tokura; Seimei Shiratori, Analytical Chemistry, 2016

A polyelectrolyte film containing metastable silver ions was applied as a quartz crystal microbalance (QCM) gas detector. The polyelectrolyte film was obtained by immersing a polyelectrolyte with numerous amine groups in a metal ion solution. The QCM detector with silver ions responded to a very ...


Surface-Anchored Poly(4-vinylpyridine)–Single-Walled Carbon Nanotube–Metal Composites for Gas Detection

05-Aug-2016 | Bora Yoon; Sophie F. Liu; Timothy M. Swager, Chemistry of Materials, 2016

A platform for chemiresistive gas detectors based upon single-walled carbon nanotube (SWCNT) dispersions stabilized by poly(4-vinylpyridine) (P4VP) covalently immobilized onto a glass substrate was developed. To fabricate these devices, a glass substrate with gold electrodes is treated with ...


Optimal placement of gas detectors: A P‐median formulation considering dynamic nonuniform unavailabilities

31-Mar-2016 | A.J. Benavides‐Serrano, M.S. Mannan, C.D. Laird, AIChE Journal, 2016

Abstract A stochastic programming formulation (SPqt), based on the P‐median problem (PMP), is proposed for determining the optimal placement of detectors in mitigation systems while considering nonuniform dynamic detector unavailabilities. Unlike previously proposed formulations, SPqt ...


Plasmonic Hydrogen Sensing with Nanostructured Metal Hydrides

08-Dec-2014 | Carl Wadell; Svetlana Syrenova; Christoph Langhammer, ACS Nano, 2014

In this review, we discuss the evolution of localized surface plasmon resonance and surface plasmon resonance hydrogen sensors based on nanostructured metal hydrides, which has accelerated significantly during the past 5 years. We put particular focus on how, conceptually, plasmonic resonances ...


Investigation of High-Temperature CO2 Capture by CaO in CaCl2 Molten Salt

28-Aug-2013 | Viktorija Tomkute; Asbjørn Solheim; Espen Olsen, Energy & Fuels, 2013

Modifications of CaO-based sorbents with various inorganic salts to overcome the degradation in the reactivity between the active material and CO2 in a carbon capture process have previously been evaluated. The present paper focuses on the performance of a novel CO2 capture technology, where ...


Underwater micro gas detector

12-Aug-2013 | Author(s): Dong Jin Cho , Sung Eun Kim , Eunbi Seo , Min Chul Lee , Jae Min Lee , Jong Soo Ko, Sensors and Actuators B: Chemical, 2013

Publication date: November 2013 Source:Sensors and Actuators B: Chemical, Volume 188 Author(s): Dong Jin Cho , Sung Eun Kim , Eunbi Seo , Min Chul Lee , Jae Min Lee , Jong Soo Ko This article presents a novel underwater micro gas detector (UMGD), which can directly detect components ...


Gas Temperature Effect on Reactive Species Generation from the Atmospheric Pressure Air Plasma

10-May-2013 | Ho Young Kim, Sung Kil Kang, Hyoung Cheol Kwon, Hyun Woo Lee, Jae Koo Lee, Plasma Processes and Polymers, 2013

Abstract Using surface type air atmospheric pressure plasma, we investigated the amount of ozone and other reactive species generation with variations of the surface temperature of an electrode through an optical emission spectrum and a tube type gas detector. Reduced version of global model ...


Use of an Accelerometer and a Microphone as Gas Detectors in the Online Quantitative Detection of Hydrogen Released from Ammonia Borane by Gas Chromatography

05-Mar-2013 | Yi-San He; Kuan-Fu Chen; Chien-Hung Lin; Min-Tsung Lin; Chien-Chung Chen; Cheng-Huang Lin, Analytical Chemistry, 2013

The use of an accelerometer as a gas detector in gas chromatography (GC) is described for the first time. A milli-whistle was connected to the outlet of the GC capillary. When the eluted and GC carrier gases pass through the capillary and milli-whistle, a sound is produced. After a fast Fourier ...
