N+-bombarded multi-walled carbon nanotubes (N+-bombarded MWCNTs), with different nitrogen atomic percentages, were achieved by different N ion beam currents using ion beam-assisted deposition (IBAD) on MWCNTs synthesized by chemical vapor deposition (CVD). Characterizations of N+-bombarded MWCNTs were evaluated by X-ray photoelectron spectroscopy (XPS),(More)
Au-Si nano-particle-decorated silicon nanowire arrays have been fabricated by Au film deposition on silicon nanowire array substrates and then post-thermal annealing under hydrogen atmosphere. Field emission measurements illustrated that the turn-on fields of the non-annealed Au-coated SiNWs were 6.02 to 7.51 V/μm, higher than that of the as-grown silicon(More)
Carbon nanotubes were subjected to doping with an energetic Ag ion beam, and the carbon nanotubes on the top of the array were transformed into amorphous carbon nanowires with embedded Ag-nanoparticles. The field emission characteristics of these nanowires were investigated. The minimum turn-on and threshold fields were 0.68 and 1.09 V/lm, respectively,(More)
BACKGROUND The aim of this study was to investigate whether the TGFA/TGFB3/MSX1 gene polymorphisms and haplotypes lead to individual differences between congenital non-syndromic hearing impairment (NSHI) patients and normal people in a Chinese population and to analyze the risk factors for NSHI. MATERIAL AND METHODS Between December 2010 and September 2014,(More)
After the publication of this work [1], we noticed an error whereby the images of Figs. 1, 2, 3 and 5 were interchanged, and therefore do not correspond to their legends. They are interchanged and therefore do not correspond to their legends. The original version of this article was corrected. The corrected figures are given below: permits unrestricted use,(More)
Graphene may have attractive properties for some biomedical applications, but its potential adverse biological effects, in particular, possible modulation when it comes in contact with blood, require further investigation. Little is known about the influence of exposure to COOH(+)-implanted graphene (COOH(+)/graphene) interacting with red blood cells and(More)
OBJECTIVE To evaluate the clinical efficacy of sorafenib as preoperative neoadjuvant therapy in patients with high risk renal cell carcinoma (RCC). MATERIALS AND METHODS Clinical data of 18 patients with high risk RCC who received surgery done successfully after preoperative neoadjuvant therapy with sorafenib in Peking Union Medical College Hospital(More)
In this paper, a new method named by Picard and weakly Picard operators methods is applied to revisit impulsive fractional differential equations in Banach spaces. By using this powerful tool, some interesting existence and uniqueness theorems and data dependence results are established in a suitable piecewise continuous functions space with piecewise(More)
