Interfacial Reaction of Fulleropyrrolidines Affecting Organic Photovoltaic Performance.

ACS applied materials & interfaces

Karakawa M, Nagai T.
PMID: 28574248
ACS Appl Mater Interfaces. 2017 Jun 28;9(25):21338-21345. doi: 10.1021/acsami.7b02155. Epub 2017 Jun 13.

Fulleropyrrolidine derivatives are intrinsically basic owing to the amino group within the pyrrolidine structure. It can be predicted that the basicity of fulleropyrrolidine may affect the photovoltaic devices containing an acidic layer (e.g., PEDOT: PSS). To clarify the effect...

Fingertip replantation is a technical challenge for microsurgeons. For successful fingertip replantation, it is important to monitor the replanted fingertip vascularity for the early detection and revision of vascular compromise. Laser speckle contrast imaging (LSCI) is a camera-based technique...

Supermicrosurgical Suture-Stent Technique for A Lymphaticovenular Bypass.

Journal of clinical medicine

Karakawa R, Yoshimatsu H, Kamiya K, Fuse Y, Yano T.
PMID: 34208378
J Clin Med. 2021 Jun 11;10(12). doi: 10.3390/jcm10122595.

BACKGROUND: Lymphaticovenular anastomosis (LVA) is a challenging procedure and requires a sophisticated supermicrosurgical technique. The aim of this study was to evaluate and establish a discrete supermicrosurgical anastomosis method using the "suture-stent technique".METHODS: Forty-eight LVA sites of twenty patients...
