    Functional single-cell analysis of T-cell activation by supported lipid bilayer-tethered ligands on arrays of nanowells by Torres, Alexis J., Contento, Rita Lucia, Gordo, Susana, Wucherpfennig, Kai W., Love, John C

    Published 2014
    “…Immobilized bilayers presenting tethered ligands on planar substrates have yielded both spatio-temporal and structural insights into how T cell receptors (TCRs) reorganize during the initial formation of synapses upon recognition of peptide antigens bound to major histocompatibility complex (MHC) molecules. The prototypical configuration of these assays, however, limits the extent to which the kinetics and structure of the supramolecular activation clusters of the synapse (that occur in seconds or minutes) can be related to subsequent complex cellular responses, such as cytokine secretion and proliferation, occurring over hours to days. …”

    Diverse cell stresses induce unique patterns of tRNA up- and down-regulation: tRNA-seq for quantifying changes in tRNA copy number by Pang, Yan Ling Joy, Abo, Ryan, Levine, Stuart S., Dedon, Peter C

    Published 2014
    “…To this end, we developed a next-generation sequencing method that exploits the paucity of ribonucleoside modifications at the 3′-end of tRNAs to quantify changes in all cellular tRNA molecules. Application of this tRNA-seq method to Saccharomyces cerevisiae identified all 76 expressed unique tRNA species out of 295 coded in the yeast genome, including all isoacceptor variants, with highly precise relative (fold-change) quantification of tRNAs. …”

    Molecular packing and electronic processes in amorphous-like polymer bulk heterojunction solar cells with fullerene intercalation by Hu, Xiao, Xiao, Ting, Xu, Haihua, Grancini, Giulia, Mai, Jiangquan, Petrozza, Annamaria, Jeng, U-Ser, Wang, Yan, Xin, Xin, Lu, Yong, Choon, Ng Siu, Ong, Beng S., Lu, Xinhui, Zhao, Ni

    Published 2014
    “…Grazing incidence X-ray scattering measurements reveal the lower-ordered nature of the BHJ system as well as an intermixing morphology with intercalation of fullerene molecules between the PFBT-T20TT lamella. Steady-state and transient photo-induced absorption spectroscopy reveal ultrafast charge transfer (CT) at the PFBT-T20TT/fullerene interface, indicating that the CT process is no longer limited by exciton diffusion. …”

    Published 2015
    “…In this work, we propose a new configuration of surface plasmon resonance (SPR) sensor that is based on graphene–MoS2 hybrid structures for ultrasensitive detection of molecules. The proposed system displays a phase-sensitivity enhancement factor of more than 500-fold when compared to the SPR sensing scheme without the graphene–MoS2 coating or with only graphene coating. …”
