Effect of salt content on the rheological properties of hydrogel based on oligomeric electrolyte.

The journal of physical chemistry. B

Kundu SK, Yoshida M, Shibayama M.
PMID: 20055469
J Phys Chem B. 2010 Feb 04;114(4):1541-7. doi: 10.1021/jp906312f.

Dynamic light scattering and oscillatory rheology experiments were performed to study the effects of various salts on the hydrogel consisting of an oligomeric electrolyte gelator, poly(pyridinium-1,4-diyliminocarbonyl-1,4-phenylenemethylene chloride) (1-Cl). Sol-gel transition temperature increased with increasing salt concentration that suggested the...

Inductive asymmetric cell division: The WRM leads the way.

Worm

Ishidate T, Kim S, Mello C, Shirayama M.
PMID: 24524013
Worm. 2013 Oct 01;2(4):e26276. doi: 10.4161/worm.26276. Epub 2013 Sep 05.

C. elegans, with its invariant cell lineage, provides a powerful model system in which to study signaling-dependent asymmetric cell division. The C. elegans β-catenin-related protein, WRM-1, specifies endoderm at the 4-cell stage during the first cell signaling-induced asymmetric cell...

Superflares on solar-type stars.

Nature

Maehara H, Shibayama T, Notsu S, Notsu Y, Nagao T, Kusaba S, Honda S, Nogami D, Shibata K.
PMID: 22622572
Nature. 2012 May 16;485(7399):478-81. doi: 10.1038/nature11063.

Solar flares are caused by the sudden release of magnetic energy stored near sunspots. They release 10(29) to 10(32) ergs of energy on a timescale of hours. Similar flares have been observed on many stars, with larger 'superflares' seen...

Dynamic light scattering microscope: accessing opaque samples with high spatial resolution.

Optics express

Hiroi T, Shibayama M.
PMID: 24105571
Opt Express. 2013 Aug 26;21(17):20260-7. doi: 10.1364/OE.21.020260.

We developed a new technique that conducts dynamic light scattering (DLS) under a microscope with high spatial resolution. This technique dramatically extends the range of DLS application from transparent to opaque samples. The total scattered electric field contains both...

CONTEXT: In patients with primary aldosteronism (PA), it remains unclear whether aldosterone-producing adenomas are likely to develop in the left or right adrenal gland.OBJECTIVE: To investigate left-right differences of PA laterality diagnoses via CT imaging and adrenal vein sampling...

Evaluation of Mesh Size in Model Polymer Networks Consisting of Tetra-Arm and Linear Poly(ethylene glycol)s.

Gels (Basel, Switzerland)

Tsuji Y, Li X, Shibayama M.
PMID: 30674826
Gels. 2018 May 25;4(2). doi: 10.3390/gels4020050.

The structure and mechanical properties of model polymer networks consisting of alternating tetra-functional poly(ethylene glycol)s (PEGs) and bis-functional linear PEGs were investigated by dynamic light scattering and rheological measurements. The sizes of the correlation blob ( ξ c )...

All-inorganic inverse perovskite solar cells using zinc oxide nanocolloids on spin coated perovskite layer.

Nano convergence

Shibayama N, Kanda H, Yusa SI, Fukumoto S, Baranwal AK, Segawa H, Miyasaka T, Ito S.

Nano Converg. 2017;4(1):18. doi: 10.1186/s40580-017-0113-2. Epub 2017 Jul 28.

We confirmed the influence of ZnO nanoparticle size and residual water on performance of all inorganic perovskite solar cells. By decreasing the size of the ZnO nanoparticles, the short-circuit current density (
