A series of semiconducting copolymers (PTAT-x) containing extended π-conjugated tetrathienoanthracene units have been synthesized. It was shown that the extended conjugation system enhanced the π-π stacking in the polymer/PC(61)BM blend films and facilitated the charge transport in heterojunction solar cell devices. After structural fine-tuning, the polymer with bulky 2-butyloctyl side chains (PTAT-3) exhibited a PCE of 5.6% when it was blended with PC(61)BM. 相似文献

A convenient supramolecular strategy for constructing a ratiometric fluorescent chemosensing ensemble, consisting of a macrocyclic host (cucurbit[8]uril CB[8]), and a pyrene-tagged amphiphilic peptide beacon (AP 1), is reported. AP 1 unfolds upon encapsulation of the pyrene termini into the hydrophobic CB[8] cavity. This changes pyrene excimer to monomer emission. Substrates with higher affinity for the CB[8] cavity can displace AP 1 from the ensemble. The released AP 1 folds again to form a pyrene excimer, which allows for the ratiometric fluorescence monitoring of the substrate. In this report, the ensemble capacity for ratiometric fluorescence monitoring of biological substrates, such as amino acid derivatives, specific peptides, and proteins, in aqueous media is demonstrated. 相似文献

Due to technological advancement, environment suffers from untreated toxic heavy metal bearing effluent coming from different
industries. Chromium (VI) is one of those heavy metals having adverse impact on ecological balance, human, and plant health
because of its carcinogenic properties. Biosorption is presented as an alternative to traditional technologies which are costly
and inefficient for treatment of industrial wastes containing low amount of heavy metals. In this study, bioremediation of
Cr (VI) ions by immobilized Bacillus cereus M1
16 was investigated in a laboratory scale packed bed up-flow column reactor. The effect of important parameters, such as the
inlet flow rate, influent concentration, and effective bed height, has been studied. External mass transfer, surface adsorption,
and intrabead mass transfer were also studied to conclude the rate limiting step for removal of Cr (VI) and to determine the
process parameters which are important for biosorption optimization. The external mass transfer coefficient was calculated
at different flow rates (6.51 × 10−2 to 7.58 × 10−2 cm/min). Using the model, the surface adsorption rate constant (k
ad) and the intrabead mass transfer coefficient (k
i) were predicted as 0.0267 × 10−3 and 0.7465 × 10−3 l/g/min, respectively. Both are much lower than the external mass transfer coefficient (k
e). The surface adsorption phenomenon is acting as the rate-limiting step due to its high resistance for removal of Cr (VI). 相似文献

Studies of structural and electrical properties have been carried out on a number of glasses with wide ranging compositions in the glass systems Li2O·MO·Bi2O3·B2O3 (where M=Zn or Cd), in order to understand the effect of transition metal (TM) ions on the structure of these glasses. The density and molar volume measurements have also been made to understand the structural changes occurring in these glasses. The dc conductivity measured in the temperature range 423-623 K obeys Arrhenius law. It increases with increase in Li2O/MO ratio. The results of infrared spectra indicate that TM ions (Zn2+ or Cd2+) behave as network former in the present system. Boron exists in both tri- and tetra-hedral units in these glasses and no boroxol ring formation takes place in the glass structure. Values of theoretical optical basicity have also been reported. 相似文献

In the present investigation an exact generalised model for anisotropic compact stars of embedding class 1 is sought with a general relativistic background. The generic solutions are verified by exploring different physical aspects, viz. energy conditions, mass–radius relation, stability of the models, in connection to their validity. It is observed that the model presented here for compact stars is compatible with all these physical tests and thus physically acceptable as far as the compact star candidates RXJ 1856-37, SAX J 1808.4-3658 (SS1) and SAX J 1808.4-3658 (SS2) are concerned. 相似文献
