We report a p-n heterojunction solid-state solar cell comprised of p-type CdTe that was electrochemically deposited onto hydrothermally synthesized vertically oriented arrays of n-type single crystal rutile TiO2 nanowire arrays (RNWAs). The nanowires were grown on fluorine doped tin oxide (FTO)-coated transparent conductive glass substrates by hydrothermal synthesis. Morphological studies revealed the TiO2 nanowires to be completely infiltrated by the CdTe. The solid-state solar cell exhibited an open circuit voltage of 0.6 V, a short-circuit current density of 3.57 mA cm(-2), a fill factor of 44% and a power conversion efficiency of 0.96%.

Capturing and detection of MCF-7 breast cancer cells with a CMOS image sensor Musayev, Javid; Altiner, Caglar; Adiguzel, Yekbun; Külah, Haluk; Eminoglu, Selim; Akın, Tayfun (2014-08-15) This paper presents a CMOS image sensor with a 32 x 32 pixel array for cell capture, detection, and quantification. Pixels measuring 15 pm x 15 mu m have a modified structure, suitable for post-CMOS electroless gold plating, which enables surface activation for cell capture without the need for any intermediate layer. This structure also increases the detection probability of captured cells, even when cells are much smaller than the pixel, owing to a special light mask implemented on pixels. Cells as small ...
Cylindrical Substrate Integrated Waveguide (CSIW) Slot Arrays with Uniform and Nonuniform Spacings Bayraktar, Omer; Aydın Çivi, Hatice Özlem (2014-08-23) Pattern synthesis of a traveling wave longitudinal slot array on the broad wall of cylindrical substrate integrated waveguide (CSIW) is presented at 25 GHz. In order to have low side lobe level (SLL) and high directivity, the Elliot's design procedure for 1 x 25 slotted waveguide array is applied to satisfy the required slot voltage distribution found by aperture projection method for evenly distributed slot array with complex slot voltage distribution. The results are compared with the design which makes u...
Reference-plane-invariant waveguide method for electromagnetic characterization of bi-axial bianisotropic metamaterials HASAR, UĞUR CEM; Yildiz, Gul; BUTE, MUSA; Muratoğlu, Abdurrahim (2018-11-01) In this paper, we investigate a reference-plane invariant (RPI) method for electromagnetic property extraction of bi-axial bianisotropic metamaterial (MM) slabs. In order to obtain unique properties, we applied the frequency varying technique in order to determine the location of the slab within its cell. For validation of the proposed method, we first simulated and then measured scattering parameters of a MM slab constructed by split-ring-resonators, next extracted its electromagnetic properties, and final...
Azimuthal anisotropy of charged particles with transverse momentum up to 100GeV/c in PbPb collisions at root S-NN=5.02 TeV Sirunyan, A. M.; et. al. (2018-01-01) The Fourier coefficients v(2) and v(3) characterizing the anisotropy of the azimuthal distribution of charged particles produced in PbPb collisions at root S-NN = 5.02 TeV are measured with data collected by the CMS experiment. The measurements cover a broad transverse momentum range, 1 10 GeV/c range, where anisotropic azimuthal distributions should reflect the path-length dependence of parton energy loss in the created medium. Results are presented in several bins of PbPb collision centrality, spanning t...
Elliptic Flow of Charm and Strange Hadrons in High-Multiplicity p plus Pb Collisions at root(NN)-N-s=8.16 TeV Sirunyan, A. M.; et. al. (2018-08-01) The elliptic azimuthal anisotropy coefficient (upsilon(2)) is measured for charm (D-0) and strange (K-S(0), Lambda, Xi(-), and Omega(-)) hadrons, using a data sample of p + Pb collisions collected by the CMS experiment, at a nucleonnucleon center-of- mass energy of root(NN)-N-s = 8.16 TeV. A significant positive upsilon(2) signal from long- range azimuthal correlations is observed for all particle species in high- multiplicity p + Pb collisions. The measurement represents the first observation of possible l...
