In this work, PbSe and PbTe sensitized TiO2 solar cells were fabricated.PbSe and PbTe nanostructure was deposited on the TiO2 surface via a drop cast method.The fabricated surfaces were examined by atomic force microscopy (AFM).Also the optical properties of the layers were studied by diffuse reflectance spectroscopy (DRS) spectra.The morphology of
It has been proven Skewers that developing urban rail transit (URT) is the key to solving the traffic problems in big cities, and transport efficiency is essential for scientific line planning and construction, operation management and sustainable development of urban rail transit.This paper focuses on the transport efficiency of the URT network an
Abstract High recurrence and metastasis rates and poor prognoses are the major challenges of current cancer therapy.Mounting evidence suggests that cancer stem cells (CSCs) play an important role in cancer development, chemoradiotherapy resistance, recurrence, and metastasis.Therefore, targeted CSC therapy has become a new strategy for solving the
ABSTRACT Ten queries of different subjects were run over yahoo, Google, Msn and Hakia search engines.Second set of experiment comprise four phrases of the same meaning but different syntax were attached to each Shampoo query and the combinations were run over Hakia search engine.Four thousand retrieved documents were classified as relevant, duplica
