Fluorescence emissions of imide compounds and end-capped polyimides enhanced by intramolecular double hydrogen bonds.
Phys. Chem. Chem. Phys. 17 , 30659-69, (2015) The structure and optical properties of a newly synthesized imide compound (DHNHPI) that forms intramolecular double hydrogen bonds (intra-HBs) were investigated. This compound exhibits intense absorption at 372 nm (ε = 5091 cm(-1) M(-1)) and strong emission ... |

Natural-cause mortality and long-term exposure to particle components: an analysis of 19 European cohorts within the multi-center ESCAPE project.
Environ. Health Perspect. 123 , 525-33, (2015) Studies have shown associations between mortality and long-term exposure to particulate matter air pollution. Few cohort studies have estimated the effects of the elemental composition of particulate matter on mortality.Our aim was to study the association be... |

Sub-50 nm metrology on extreme ultra violet chemically amplified resist--A systematic assessment.
Rev. Sci. Instrum. 86 , 103702, (2015) With lithographic patterning dimensions decreasing well below 50 nm, it is of high importance to understand metrology at such small scales. This paper presents results obtained from dense arrays of contact holes (CHs) with various Critical Dimension (CD) betw... |

Flow cytometric measurement of cytoplasmic pH: a critical evaluation of available fluorochromes.
Cytometry 7(4) , 347-55, (1986) Three pH-sensitive fluorochromes-4-methyl-umbelliferone(4MU),2, 3-dicyano-hydroquinone (DCH), and 2',7'-bis(carboxyethyl)-5,6-carboxy fluorescein (BCECF)--were evaluated for their resolution, range, and stability of cellular fluorescence. Flow cytometric tech... |

Ratiometric measurement of intracellular pH in cultured human keratinocytes using carboxy-SNARF-1 and flow cytometry.
Cytometry 12(2) , 127-32, (1991) In this study we describe a method to measure intracellular pH in cultured human keratinocytes using flow cytometry. Keratinocytes pose a technical problem because the population is heterogeneous with respect to size and metabolic activity (nonspecific estera... |

Measurement of intracellular pH using flow cytometry with carboxy-SNARF-1.
Cytometry 14(8) , 916-21, (1993) The new intracellular pH (pH(i)) dye carboxy-seminaphthorhodafluor (SNARF-1) was compared to the established dye 2,3-dicyanohydroquinone (DCH) using flow cytometry. Both dyes give high-resolution pH(i) measurements. SNARF-1 remains trapped within cells much l... |

Changes in intracellular pH and pH regulating mechanisms in somitic cells of the early chick embryo: a study using fluorescent pH-sensitive dye.
J. Physiol. 405 , 385-95, (1988) 1. Measurements of intracellular pH (pHi) have been made using the fluorescent dye dicyano-hydroquinone (DCH) in somites isolated from 2-day-old chick embryos. Measurements of pHi, from freshly dissected somites, gave values of 7.18 +/- 0.02 (mean +/- S.D., n... |

Two-photon excitation fluorescence pH detection using 2,3-dicyanohydroquinone: a spectral ratiometric approach.
J. Microsc. 217(Pt 3) , 260-4, (2005) The use of 2,3-dicyanohydroquinone (DCHQ) as an emission ratiometric probe of pH in vitro and in fibroblast cells was evaluated using two-photon excitation fluorescence microscopy (TPEFM). In addition, methods for spectrally calibrating the Zeiss LSM510 META ... |
