We demonstrate that the near-infrared （NIR） absorptivity of semiconducfing single-walled carbon nanotubes （s-sWCNts） can be harnessed in blended heterojunctions with the fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester （PCBM）. Photogenerated charge separation is efficiently driven by the ultrahigh interracial area of the blends and the favorable energy offsets between the two materials. NIR-sensitive photovoltaic and photodetector devices utilizing the stack （indium tin oxide/ca. 10 nm s-sWCNt：PCBM/100 nm CJ10 nm 2,9- dimethyl-4,7-diphenyl-],10-phenanthroline （BCP）/Ag） were fabricated with NIR power conversion efficiencies 〉1.3% and peak, zero bias external quantum efficiency of 18% at λ = 1205 nm.

this work was conducted to determine the practicability of using a new adsorbent 4-ethyl thiosemicarbazide intercalated, organophilic calcined hydrotalcite （EtsC-OHtC） for the removal of uranium （U（Ⅵ））, and thorium （th（Ⅳ）） from water and wastewater. the FtIR analysis helped in realizing the involvement of nitrogen and sulphur atoms of EtsC in binding the metal ions through complex formation. Parameters like adsorbent dosage, solution pH, initial metal ions concentration, contact time and ionic strength, that influence adsorption phenomenon, were studied. the optimum pH for maximum adsorption of U（VI） and th（IV） was found to be in the range 4.0-6.0. the contact time required for reaching equilibrium was 4 hr. the pseudo second-order kinetic model was the best fit to represent the kinetic data. Analysis of the equilibrium adsorption data using Langmuir, Freundlich and sips models showed that the Freundlich model was well suited to describe the metal ions adsorption. the KF values were 25.43 and 29.11 mg/g for U（Ⅵ） and th（Ⅳ）, respectively, at 30℃. the adsorbent can be regenerated effectively from U（Ⅵ） and th（Ⅳ） loaded ones using 0.01 mol/L HC1. the new adsorbent was quite stable for many cycles, without much reduction in its adsorption capacity towards the metals.

Design of a robust production facility layout with minimum handling cost （MHC） presents an appropriate approach to tackle facility layout problems in a dynamic volatile environment, in which product demands randomly change in each planning period. the objective of the design is to find the robust facility layout with minimum total material handling cost over the entire multiperiod planning horizon. this paper proposes a new mathematical model for designing robust machine layout in the stochastic dynamic environment of manufacturing systems using quadratic assignment problem （QAP） formulation. In this investigation, product demands are assumed to be normally distributed random variables with known expected value, variance, and covariance that randomly change from period to period. the proposed model was verified and validated using randomly generated numerical data and benchmark examples. the effect of dependent product demands and varying interest rate on the total cost function of the proposed model has also been investigated. sensitivity analysis on the proposed model has been performed. Dynamic programming and simulated annealing optimization algorithms were used in solving the modeled example problems.
