PMID: 26973092
Sci Rep. 2016 Mar 14;6:22838. doi: 10.1038/srep22838.

The high electrical and drastically-low thermal conductivities, a vital goal for high performance thermoelectric (TE) materials, are achieved in Si-based nanoarchitecture composed of Si channel layers and epitaxial Ge nanodots (NDs) with ultrahigh areal density (~10(12) cm(-2)). In this...

The dielectric constant is a key parameter that determines both optical and electronic properties of materials. It is desirable to tune electronic properties though dielectric engineering approach. Here, we present a systematic approach to tune carrier mobilities of hybrid...

Impact of Surface Potential on Apatite Formation in Ti Alloys Subjected to Acid and Heat Treatments.

PMID: 28946646
Materials (Basel). 2017 Sep 24;10(10). doi: 10.3390/ma10101127.

Titanium metal (Ti) and its alloys are widely used in orthopedic and dental fields. We have previously shown that acid and heat treatment was effective to introduce bone bonding, osteoconduction and osteoinduction on pure Ti. In the present study,...

Re-evaluation of all-plastic organic dye laser with DFB structure fabricated using photoresists.

Scientific reports

Tsutsumi N, Nagi S, Kinashi K, Sakai W.
PMID: 27703217
Sci Rep. 2016 Oct 05;6:34741. doi: 10.1038/srep34741.

Organic solid-state lasers (OSSLs) with distributed feedback structures can detect nanoscale materials and therefore offer an attractive sensing platform for biological and medical applications. Here we investigate the lasing characteristics, i.e., the threshold and slope efficiency, as a function...

Muscle Shear Moduli Changes and Frequency of Alternate Muscle Activity of Plantar Flexor Synergists Induced by Prolonged Low-Level Contraction.

Frontiers in physiology

Akagi R, Fukui T, Kubota M, Nakamura M, Ema R.
PMID: 28979212
Front Physiol. 2017 Sep 20;8:708. doi: 10.3389/fphys.2017.00708. eCollection 2017.

During prolonged low-level contractions, synergist muscles are activated in an alternating pattern of activity and silence called as alternate muscle activity. Resting muscle stiffness is considered to increase due to muscle fatigue. Thus, we investigated whether the difference in...

Sudachitin, a polymethoxylated flavone, improves glucose and lipid metabolism by increasing mitochondrial biogenesis in skeletal muscle.

Nutr Metab (Lond). 2014 Jul 04;11:32. doi: 10.1186/1743-7075-11-32. eCollection 2014.

BACKGROUND: Obesity is a major risk factor for insulin resistance, type 2 diabetes, and stroke. Flavonoids are effective antioxidants that protect against these chronic diseases. In this study, we evaluated the effects of sudachitin, a polymethoxylated flavonoid found in...

Primary neurolymphomatosis of the lower cranial nerves presenting as Dysphagia and hoarseness: a case report.

Journal of neurological surgery reports
