We report the experimental evidence for the formation of multi-quantum dots in a hydrogenated single-layer graphene flake. The existence of multi-quantum dots is supported by the low-temperature measurements on a field effect transistor structure device. The resulting Coulomb blockade diamonds shown in the color scale plot together with the number of(More)
A Sb-doped ZnO microrod array was fabricated on an Al-doped ZnO thin film by electrodeposition. Strong violet luminescence, originated from free electron-to-acceptor level transitions, was identified by temperature-dependent photoluminescence measurements. This acceptor-related transition was attributed to substitution of Sb dopants for Zn sites, instead of(More)
We have performed transport measurements on a gallium phosphide antimonide (GaPSb) film grown on GaAs. At low temperatures (T), transport is governed by three-dimensional Mott variable range hopping (VRH) due to strong localization. Therefore, electron-electron interactions are not significant in GaPSb. With increasing T, the coexistence of VRH conduction(More)
The electron transport behavior in chemically reduced graphene oxide (rGO) sheets with different thicknesses of 2, 3, and 5 nm was investigated. The four-probe method for the sheet resistance (R(S)) measurement on the intensively reduced graphene oxide samples indicates an Arrhenius characteristic of the electron transport at zero magnetic field B = 0,(More)
Bilateral simultaneous transaxillary sympathectomies (BSTS) were established in order to achieve a one-stage transaxillary sympathectomy in the treatment of palmar hyperhidrosis. The features of the BSTS were the patient's supine operative position, parapectoral incision, and bilateral simultaneous procedures. BSTS were safely performed on 60 patients(More)
18506 Background: Informal caregivers of prostate cancer patients often experience chronic psychological stress that may adversely impact their physical and mental health, and their ability to care for their families and the patient. This study aims to determine the association between perceived and biological stress among informal caregivers of prostate(More)
algal symbionts to photo-inhibition resulting from the perturbation of coral gastrodermal membrane trafficking. The same oleosin isoforms are present in oil bodies of rice embryo and aleurone layer while caleosin exists only in those of the embryo.derived growth factor regulates breast cancer cell invasion by modulating epithelial-mesenchymal transition.(More)
