Broadly tunable subterahertz emission from internal branches of the current-voltage characteristics of superconducting Bi2Sr2CaCu2O(8+δ) single crystals.

Physical review letters

Tsujimoto M, Yamamoto T, Delfanazari K, Nakayama R, Kitamura T, Sawamura M, Kashiwagi T, Minami H, Tachiki M, Kadowaki K, Klemm RA.
PMID: 22463446
Phys Rev Lett. 2012 Mar 09;108(10):107006. doi: 10.1103/PhysRevLett.108.107006. Epub 2012 Mar 09.

Continuous, coherent subterahertz radiation arises when a dc voltage is applied across a stack of the many intrinsic Josephson junctions in a Bi2Sr2CaCu2O(8+δ) single crystal. The active junctions produce an equal number of I-V characteristic branches. Each branch radiates...

Purification and Some Properties of p-Nitrophenyl-β-D-glucoside-hydrolyzing Enzymes in Culture Filtrate of Bacillus circulans KA-304 Grown on Cell-wall Preparation of Schizophyllum commune.

Mizuno K, Awazu N, Tachiki T.
PMID: 27393352
Biosci Biotechnol Biochem. 1998;62(1):39-43. doi: 10.1271/bbb.62.39.

Hydrolyzing activities toward p-nitrophenyl (p-NP)-β-D-glucoside and laminarin in a culture filtrate of Bacillus circulans KA-304, which has been observed to form protoplasts from Schizophyllum commune mycelia, increased when the bacterium was grown on a cell-wall preparation (CWP) of S....

Implementation of tetra-poly(ethylene glycol) hydrogel with high mechanical strength into microfluidic device technology.

Biomicrofluidics. 2013 Sep 23;7(5):54109. doi: 10.1063/1.4822033. eCollection 2013.

Hydrogels have several excellent characteristics suitable for biomedical use such as softness, biological inertness and solute permeability. Hence, integrating hydrogels into microfluidic devices is a promising approach for providing additional functions such as biocompatibility and porosity, to microfluidic devices....

Possible tricritical point in phase diagrams of interlayer josephson-vortex systems in high- T(c) superconductors.

Physical review letters

PMID: 10978111
Phys Rev Lett. 2000 Sep 18;85(12):2577-80. doi: 10.1103/PhysRevLett.85.2577.

A critical value in the product of the anisotropy parameter and the magnetic field is observed in interlayer Josephson-vortex systems by extensive Monte Carlo simulations. Below (above) this critical value the thermodynamic phase transition between the normal and the...

Non-destructive on-chip cell sorting system with real-time microscopic image processing.

J Nanobiotechnology. 2004 Jun 03;2(1):5. doi: 10.1186/1477-3155-2-5.

Studying cell functions for cellomics studies often requires the use of purified individual cells from mixtures of various kinds of cells. We have developed a new non-destructive on-chip cell sorting system for single cell based cultivation, by exploiting the...

Molecular photoelectric switch using a mixed SAM of organic [60]fullerene and [70]fullerene doped with a single iron atom.

J Am Chem Soc. 2011 Jun 29;133(25):9932-7. doi: 10.1021/ja203224d. Epub 2011 Jun 07.

We describe a photoswitch fabricated on indium tin oxide (ITO) as a self-assembled monolayer (SAM) of two fullerene molecules, a purely organic [60]fullerene that generates an anodic current and a [70]fullerene doped with a single iron atom. This device...

Maternal exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin and the body burden in offspring of long-evans rats.

PMID: 21432160
Environ Health Prev Med. 2005 Jan;10(1):21-32. doi: 10.1265/ehpm.10.21.

OBJECTIVES: In utero and lactational exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) results in a wide variety of developmental effects in pups at doses much lower than those causing overt toxicity in adult animals. We investigated the relationship between tissue concentrations of...

Orthogonally functionalized naphthodithiophenes: selective protection and borylation.

Organic letters

Org Lett. 2012 Sep 21;14(18):4718-21. doi: 10.1021/ol301797g. Epub 2012 Sep 12.

Selective functionalization protocols of naphtho[1,2-b;5,6-b']dithiophene (NDT3) by combining protection of the thiophene α-positions and direct borylation on the naphthalene core are described, which allows synthesizing a number of new NDT3-based building blocks with various substituents and isomeric NDT3-based polymers...

Pronounced muscle deoxygenation during supramaximal exercise under simulated hypoxia in sprint athletes.

Journal of sports science & medicine

PMID: 24149959
J Sports Sci Med. 2008 Dec 01;7(4):512-9. eCollection 2008.

The purpose of this study was to determine whether acute hypoxia alters the deoxygenation level in vastus lateralis muscle during a 30 s Wingate test, and to compare the muscle deoxygenation level between sprint athletes and untrained men. Nine...
