The elastodynamic body-wave field outside a fluid-filled open borehole due to a monopole source in the fluid, is reduced to the radiation-field due to a suitable equivalent force system (EFS) in the absence of the borehole, consisting of a monopole plus a vertical dipole. Theoretical seismograms of the EFS displacements in the solid are shown to be in excellent agreement with those obtained fro...

We have examined the electrocatalytic activity of iron phthalocyanine (FePc) and perchlorinated 16(Cl)FePc for oxygen reduction reaction (ORR) in alkaline medium with two molecules either adsorbed on external surface single-wall carbon nanotubes (SWCNT) or covalently anchored via an axial pyridine ligand pyridine-functionalized (py-SWCNT). Regardless particular type, ORR is higher when substrat...

Redox reaction [Fe(CN)6] 3– / [Fe(CN)6] 4– has been studied with a Single-Walled Carbon Nanotube (SWCNT)-coated Glassy Carbon Electrode (GCE), SWCNT-coated Gold Electrode (GE) and a lab-made SWCNT-TPLF (SWCNT-Thin-Paper-Like-Film) Electrode. The SWCNT-modified electrode has shown a well-defined redox peak compared to bare electrodes. Cyclic voltammetry was used in 50.0 × 10–3 M aqueous solution...

UNLABELLED In this study, carboxylic acid functionalized single walled carbon nanotubes (f-SWCNT-COOH) was shown to support the viability and ex vivo expansion of freeze-thawed, non-enriched hematopoietic stem and progenitor cells (HSPC) in human umbilical cord blood-mononucleated cells (UCB-MNC). Our in vitro experiments showed that f-SWCNT-COOH increased the viability of the CD45(+) cells eve...

Variable fill fluid couplings are used in the speed control units. Also, variation in coupling oil volume is used in adapting one size of coupling to a wider range of power transmission applications. Available model for the partially filled fluid couplings, has a good performance for couplings with fixed amount of oil but their performance will be degraded if they are used for the variable fill...

Free vibrations of zigzag single-wall carbon nanotubes SWCNTs of aspect ratio length/diameter 6 and with ends traction-free have been studied using molecular mechanics MM simulations with the MM3 potential. It is found that the frequencies of inextensional the Love and the Rayleigh modes of an n, 0 SWCNT saturate at the circumferential wave number of either n−1 /2 or n /2 where n is odd or even...

در قسمت اول این پایان نامه، ابتدا عامل دار کردن نانولوله های کربنی تک دیواره با گروه بنزونیتریل بررسی می شود. سپس در واکنش های بعدی، برای اولین بار اتصال مستقیم آزیترومایسین و مشتق n-دمتیل به دیواره swcnt بررسی می شود. برای این هدف، پیوندهای استری یا تیوآمیدی قابل شکست، تشکیل شده تا آزیترومایسین را به swcnt متصل کنند که نتیجه آن رزونانس آزیترومایسین-نانولوله های کربنی تک دیواره است. این پیوندها...

The reaction of Group 6 metals with SWCNT has the potential to bridge the resistive SWCNT . . . SWCNT junctions by the formation of “Cr(SWCNT)2” complexes analogous to Cr(C6H6)2. This study reports that the formation of such species is very sensitive to oxidation by a residual iron oxide catalyst used for the growth of the SWCNTs and adsorbed/bound oxygen functionality. The reaction of raw HiPc...

Single-walled carbon nanotubes (SWCNTs) are potentially strong optical absorbers with tunable absorption bands depending on their chiral indices (n, m). Their application for solar energy conversion is difficult because of the large binding energy (>100 meV) of electron-hole pairs, known as excitons, produced by optical absorption. Recent development of photovoltaic devices based on SWCNTs as l...

Subtle changes in the structure of nanoparticles influence their surface tension and corresponding interaction with cells and proteins. Here, the interaction of the single wall carbon nanotube (SWCNT) and multiwall carbon nanotube (MWCNT) with different surface tension with tau protein was evaluated using a variety of techniques including far and near circular dichroism, fluorescence spectrosco...
