A Novel Mechanism for Chemical Sensing Based on Solvent-Fluorophore-Substrate Interaction: Highly Selective Alcohol and Water Sensor with Large Fluorescence Signal Contrast.

ACS applied materials & interfaces

Chung K, Yang DS, Jung J, Seo D, Kwon MS, Kim J.
PMID: 27668520
ACS Appl Mater Interfaces. 2016 Oct 19;8(41):28124-28129. doi: 10.1021/acsami.6b07020. Epub 2016 Oct 06.

Differentiation of solvents having similar physicochemical properties, such as ethanol and methanol, is an important issue of interest. However, without performing chemical analyses, discrimination between methanol and ethanol is highly challenging due to their similarity in chemical structure as...

Adv Mater. 2015 May 20;27(19):3045-52. doi: 10.1002/adma.201500233. Epub 2015 Apr 09.

High-mobility and low-voltage-operated organic field-effect transistors (OFETs) are demonstrated by the design of a new fluorinated benzothiadiazole-based conjugated polymer with fluorinated high-k polymer dielectrics. A record-breaking high hole mobility of 9.0 cm(2) V(-1) s(-1) for benzothiadiazole-based semiconducting polymers is...

In Situ control of gas flow by modification of gas-solid interactions.

Physical review letters

Seo D, Ducker WA.
PMID: 24206496
Phys Rev Lett. 2013 Oct 25;111(17):174502. doi: 10.1103/PhysRevLett.111.174502. Epub 2013 Oct 25.

The boundary condition for gas flow at the solid-gas interface can be altered by in situ control of the state of a thin film adsorbed to the solid. A monolayer of ocatadecyltrichlorosilane (OTS) reversibly undergoes a meltinglike transition. When...

Modeling the downward transport of (210)Pb in Peatlands: Initial Penetration-Constant Rate of Supply (IP-CRS) model.

Olid C, Diego D, Garcia-Orellana J, Cortizas AM, Klaminder J.
PMID: 26476062
Sci Total Environ. 2016 Jan 15;541:1222-1231. doi: 10.1016/j.scitotenv.2015.09.131. Epub 2015 Nov 11.

The vertical distribution of (210)Pb is commonly used to date peat deposits accumulated over the last 100-150 years. However, several studies have questioned this method because of an apparent post-depositional mobility of (210)Pb within some peat profiles. In this...

Study of reverse micelles of di-isobutyl-phenoxy-ethoxy-ethyl-dimethyl-benzyl ammonium methacrylate in benzene by nuclear magnetic resonance spectroscopy.

Journal of colloid and interface science

Emin SM, Denkova PS, Papazova KI, Dushkin CD, Adachi E.
PMID: 17074357
J Colloid Interface Sci. 2007 Jan 01;305(1):133-41. doi: 10.1016/j.jcis.2006.08.013. Epub 2006 Aug 17.

(1)H NMR spectroscopy was used to investigate the aggregation of the surfactant di-isobutyl-phenoxy-ethoxy-ethyl-dimethyl-benzyl ammonium methacrylate (Hyamine-M) in benzene. Adding water makes swollen reverse micelles (microemulsion droplets). The droplets also contain cadmium ions and the sodium salt of the methacrylic...
