Peiris TAN, Baranwal AK, Kanda H, Fukumoto S, Kanaya S, Cojocaru L, Bessho T, Miyasaka T, Segawa H, Ito S.
PMID: 28426040
Nanoscale. 2017 May 04;9(17):5475-5482. doi: 10.1039/c7nr00372b.

In this article, we demonstrate for the first time a mesoscopic printable perovskite solar cell (PSC) using NiO as the hole transporting material and low-temperature processed carbon as the counter electrode. A single deposition method assisted by N

Thiophene-Fused π-Systems from Diarylacetylenes and Elemental Sulfur.

Journal of the American Chemical Society

Meng L, Fujikawa T, Kuwayama M, Segawa Y, Itami K.

J Am Chem Soc. 2016 Aug 17;138(32):10351-5. doi: 10.1021/jacs.6b06486. Epub 2016 Aug 08.

A simple yet effective method for the formation of thiophene-fused π-systems is reported. When arylethynyl-substituted polycyclic arenes were heated in DMF in the presence of elemental sulfur, the corresponding thiophene-fused polycyclic arenes were obtained via cleavage of the ortho-C-H...

Minimal model of stochastic athermal systems: origin of non-Gaussian noise.

Physical review letters

Kanazawa K, Sano TG, Sagawa T, Hayakawa H.
PMID: 25793791
Phys Rev Lett. 2015 Mar 06;114(9):090601. doi: 10.1103/PhysRevLett.114.090601. Epub 2015 Mar 03.

For a wide class of stochastic athermal systems, we derive Langevin-like equations driven by non-Gaussian noise, starting from master equations and developing a new asymptotic expansion. We found an explicit condition whereby the non-Gaussian properties of the athermal noise...

Copper ESEEM and HYSCORE through ultra-wideband chirp EPR spectroscopy.

The Journal of chemical physics

Segawa TF, Doll A, Pribitzer S, Jeschke G.
PMID: 26233121
J Chem Phys. 2015 Jul 28;143(4):044201. doi: 10.1063/1.4927088.

The main limitation of pulse electron paramagnetic resonance (EPR) spectroscopy is its narrow excitation bandwidth. Ultra-wideband (UWB) excitation with frequency-swept chirp pulses over several hundreds of megahertz overcomes this drawback. This allows to excite electron spin echo envelope modulation...

Impact of dyslipidemic components of metabolic syndrome, adiponectin levels, and anti-diabetes medications on malondialdehyde-modified low-density lipoprotein levels in statin-treated diabetes patients with coronary artery disease.

Diabetology & metabolic syndrome

PMID: 24314067
Diabetol Metab Syndr. 2013 Dec 06;5(1):77. doi: 10.1186/1758-5996-5-77.

BACKGROUND: A residual risk of cardiovascular disease tends to persist despite standard prevention therapy with statins. This may stem partly from increased oxidized low-density lipoprotein (LDL) levels. However, how oxidized LDL can be further reduced beyond statin therapy in...

Spectral splitting photovoltaics using perovskite and wideband dye-sensitized solar cells.

Nature communications

Kinoshita T, Nonomura K, Joong Jeon N, Giordano F, Abate A, Uchida S, Kubo T, Seok SI, Nazeeruddin MK, Hagfeldt A, Grätzel M, Segawa H.

Nat Commun. 2015 Nov 05;6:8834. doi: 10.1038/ncomms9834.

The extension of the light absorption of photovoltaics into the near-infrared region is important to increase the energy conversion efficiency. Although the progress of the lead halide perovskite solar cells is remarkable, and high conversion efficiency of >20% has...

Caffeine and contraction synergistically stimulate 5'-AMP-activated protein kinase and insulin-independent glucose transport in rat skeletal muscle.

Physiological reports

5'-Adenosine monophosphate-activated protein kinase (AMPK) has been identified as a key mediator of contraction-stimulated insulin-independent glucose transport in skeletal muscle. Caffeine acutely stimulates AMPK in resting skeletal muscle, but it is unknown whether caffeine affects AMPK in contracting muscle....
