Soft X-ray emission spectroscopy of aqueous myoglobin upon Fe 2p core excitation was carried out using a liquid cell with a 150 nm-thick polyimide window in a high vacuum chamber below 1×10−7 Pa. Fe 2p soft X-ray emission from the heme center of a met-myoglobin powder was effectively detected compared to that of an Fe2O3 powder. Fe 2p soft X-ray emission spectra for a series of aqueous-myoglobi...

Copper and zinc phthalocyanines and porphyrins are used in organic light emitting diodes and dye-sensitized solar cells. Using near edge x-ray absorption fine structure (NEXAFS) spectroscopy at the Cu 2p and Zn 2p edges, the unoccupied valence states at the Cu and Zn atoms are probed and decomposed into 3d and 4s contributions with the help of density functional calculations. A comparison with ...

We have observed the two-proton radioactivity of the previously unknown (19)Mg ground state by tracking the decay products in-flight. For the first time, the trajectories of the 2p-decay products, (17)Ne+p+p, have been measured by using tracking microstrip detectors which allowed us to reconstruct the 2p-decay vertices and fragment correlations. The half-life of (19)Mg deduced from the measured...

We developed two-photon scanning patterned illumination microscopy (2P-SPIM) for super-resolution two-photon imaging. Our approach used a traditional two-photon microscopy setup with temporally modulated excitation to create patterned illumination fields. Combing nine different illuminations and structured illumination reconstruction, super-resolution imaging was achieved in two-photon microsco...

The investigations of Si 1s and 2p photoelectron spectra of a poly-Si plate with natural oxide layers based on high energy excitation using X-ray tubes with three kinds of target (Mg K(alpha), Zr L(alpha) and Ag L(alpha)) and on the theoretical calculations using DV-Xalpha were presented. From the comparison between the shift values of Si 1s and 2p corresponding with the metal and oxide, it was...

Two-pore domain K(+) (K(2P)) channels that help set the resting membrane potential of excitable and nonexcitable cells are expressed in many kinds of cells and tissues. However, the expression of K(2P) channels has not yet been reported in bovine germ cells. In this study, we demonstrate for the first time that K(2P) channels are expressed in the reproductive organs and germ cells of Korean cat...

During the present study rhizosphere soil of four halophytic weeds viz., Chrysopogon aucheri, Lactuca dissecta, Solanum surattense and Sonchus arvensis growing in saline soil of Khewra salt range and Solanum surattense growing in arid region of Attock were used for isolating phosphate solubilizing bacteria. The objective of this study was to explore the abilities of phosphate solubilization, pr...

PURPOSE Advances in two-photon (2P) deep tissue imaging provide powerful options for simultaneously viewing multiple fluorophores within tissues. We determined imaging parameters for optimally visualizing three fluorophores in the human trabecular meshwork (TM) to simultaneously detect broad-spectrum autofluorescence and multiple fluorophores through a limited number of emission filters. METH...

Bulk boron was analyzed using both XPS and high-resolution high energy x-ray photoelectron spectroscopy. The spectra of obtained monochromatic Al Kα radiation include survey scan B 1s, O N C Ar 2p. Cr with at 5414.8 eV 2p, 1s.
