Observation of the spin Seebeck effect

KI Uchida, S Takahashi, K Harii, J Ieda, W Koshibae… - Nature, 2008 - nature.com
… 12), we estimate the spin Seebeck coefficient for Ni 81 Fe 19 to be S S = -2 nV K -1 at 300
K, which is different from the conventional Seebeck coefficient of -20 μV K -1 measured for the …

Spin seebeck insulator

K Uchida, J Xiao, H Adachi, J Ohe, S Takahashi… - Nature materials, 2010 - nature.com
… /Pt sample is uniformly heated to 320 K, indicating that an in-plane temperature gradient is
necessary for the observed voltage generation (note that 320 K is much lower than the Curie …

Broadly reactive and highly sensitive assay for Norwalk-like viruses based on real-time quantitative reverse transcription-PCR

…, S Kojima, M Shinohara, K Uchida… - Journal of clinical …, 2003 - Am Soc Microbiol
We have developed an assay for the detection of Norwalk-like viruses (NLVs) based on
reverse transcription-PCR (RT-PCR) that is highly sensitive to a broad range of NLVs. We …

Immunohistochemical detection of 4-hydroxynonenal protein adducts in Parkinson disease.

A Yoritaka, N Hattori, K Uchida… - Proceedings of the …, 1996 - National Acad Sciences
There is growing evidence that oxidative stress and mitochondrial respiratory failure with
attendant decrease in energy output are implicated in nigral neuronal death in Parkinson …

Protein-bound acrolein: potential markers for oxidative stress

K Uchida, M Kanematsu, K Sakai… - Proceedings of the …, 1998 - National Acad Sciences
Acrolein (CH 2 =CH—CHO) is known as a ubiquitous pollutant in the environment. Here we
show that this notorious aldehyde is not just a pollutant, but also a lipid peroxidation product …

4-Hydroxy-2-nonenal: a product and mediator of oxidative stress

K Uchida - Progress in lipid research, 2003 - Elsevier
… adducts were demonstrated to account for <10% of the total protein carbonyl groups
associated with the modified proteins that accumulate in liver hepatocytes of old rats (Uchida and …

Role of reactive aldehyde in cardiovascular diseases

K Uchida - Free radical biology and medicine, 2000 - Elsevier
… The acrolein analogue, crotonaldehyde, also generates the FDP-like adduct as the major
product upon reaction with lysine (Uchida et al., unpublished observation), suggesting that the …

Observation of longitudinal spin-Seebeck effect in magnetic insulators

K Uchida, H Adachi, T Ota, H Nakayama… - Applied Physics …, 2010 - pubs.aip.org
We propose a longitudinal spin-Seebeck effect (SSE), in which a magnon-induced spin
current is injected parallel to a temperature gradient from a ferromagnet into an attached …

Theory of magnon-driven spin Seebeck effect

J Xiao, GEW Bauer, K Uchida, E Saitoh, S Maekawa - Physical Review B, 2010 - APS
K. Uchida et al., Nature London 455, 778 2008 . We explain this effect by spin pumping at
the contact that is proportional to the spin-mixing conductance of the interface, the inverse of a …
