Green fluorescent protein (GFP) molecules are attached to titanium dioxide and cadmium oxide nanoparticles via sol–gel method and fluorescence dynamics of such a protein–metal oxide assembly is investigated with a conventional time correlated single photon counting technique. As compared to free fluorescent protein molecules, time-resolved experiments show that the fluorescence lifetime of GFP molecules bound to these metal oxide nanoparticles gets shortened dramatically. Such a decrease in the lifetime is measured to be 22 and 43 percent for cadmium oxide and titanium dioxide respectively, which is due to photoinduced electron transfer mechanism caused by the interaction of GFP molecules (donor) and metal oxide nanoparticles (acceptor). Our results yield electron transfer rates of 3.139×108 s−1 and 1.182×108 s−1 from the GFP molecules to titanium dioxide and cadmium oxide nanoparticles, respectively. The electron transfer rates show a marked decrease with increasing driving force energy. This effect represents a clear example of the Marcus inverted region electron transfer process. 相似文献

Formamidinium lead triiodide (FAPbI3)‐based perovskite materials are of interest for photovoltaics in view of their close‐to‐ideal bandgap, allowing absorption of photons over a broad solar spectrum. However, FAPbI3‐based materials suffer from a notorious phase transition from the photoactive black phase (α‐FAPbI3) to nonperovskite yellow phase (δ‐FAPbI3) under ambient conditions. This transition dramatically reduces light absorbtion, thus, degrading the photovoltaic performance and stability of ensuring solar cells. In this study, 1‐hexyl‐3‐methylimidazolium iodide (HMII) ionic liquid (IL) is employed as an additive for the first time in FAPbI3 perovskite to overcome the above‐mentioned issues. HMII incorporation facilitates the grain coarsening of FAPbI3 crystal owing to its high‐polarity and high‐boiling point, which yields liquid domains between neighboring grains to reduce the activation energy of the grain‐boundary migration. As a result, the FAPbI3 active layer exhibits micron‐sized grains with substantially suppressed parasitic traps with an Urbach energy reduced by 2 meV. Hence, the resulting perovskite solar cell achieves an efficiency of 20.6% with notable increase in open circuit voltage (VOC) of 80 mV compared with HMII‐free cells (17.1%). More importantly, the HMII‐doped FAPbI3‐based cells show a striking enhancement in shelf‐stability under high humidity and thermal stress, retaining >80% of their initial efficiencies at 60 ± 10% relative humidity and ≈95% at 65 °C. 相似文献

This paper deals with two different forms of the conformable fractional Benjamin–Bona–Mahony (BBM) equations by an analytical method. These physical models have important applications for describing the propagation of optical pulses in non-linear media. The conformable fractional symmetric BBM equation and the conformable time fractional Equal-width (EW) equation are considered. The extended Jacobi’s elliptic function expansion scheme are used to extract explicit solitons. 相似文献

Technetium-99m diaminocyclohexane (DACH) is a new tubular agent excreted via a cationic transport mechanism, like cyclosporine-A (CsA). It is expected that 99mTc-DACH will permit effective assessment of tubular function in CsA-treated patients. To establish the pharmacokinetic characteristics of 99mTc-DACH and to ascertain whether this new agent is useful in CsA-treated patients, 11 healthy volunteers and 15 CsA-treated patients underwent renal imaging and clearance studies using 99mTc-DACH and chromium-51 ethylene diamine tetra-acetic acid (EDTA). 99mTc-DACH yielded satisfactory dynamic renal images in all participants. The mean plasma clearance of 99mTc-DACH was significantly greater than that of 51Cr-EDTA in volunteers (109.4?19.7 ml/min versus 86.6 +/- 13.7 ml/min, P<0.05). However, the urinary excretion of 99mTc-DACH at 90 min was significantly lower than that of 51Cr-EDTA (46.1% +/- 9.3% versus 53.1% +/- 8.6%, P<0.05), most probably due to its partial parenchymal retention. The elimination half-life of 99mTc-DACH was significantly increased in CsA-treated patients in comparison to volunteers, and consequently the plasma clearance values were significantly suppressed in these patients, in contrast to 51Cr-EDTA and endogenous creatinine clearance values. In conclusion, our findings indicate that 99mTc-DACH, as a sensitive marker of cationic tubular function, could be used to monitor renal haemodynamics in patients receiving CsA treatment. 相似文献

Optical solitions to the Biswas–Milovic model have been investigated analytically with the help of the generalized Kudryashov method. Four types of nonlinear are considered. They are Kerr law, Power law, parabolic law and dual-power law. As a result, exact solitary wave solutions are obtained. 相似文献
