Title
Natural fibrous proteins as a source for inspiration for the design of novel nano-biomaterials

Language

Abstract

Natural fibrous proteins include families found in natural materials such as wool, silk, in tissue components such as collagen, elastin or
in virus and bacteriophage adhesins. They have long fascinated scientists and engineers due to their mechanical and elastic properties, and considerable efforts have been made in order to
produce artificial materials inspired from these natural proteins.
Repetitive sequences, or "building blocks" derived from these fibrous proteins can self-assemble into well-defined structures (wires, tubes etc.) under mild conditions and are relatively inexpensive and easy to manufacture. Of particular interest is the possibility of using these peptide nanofibers and nanotubes as templates for the growth of
inorganic materials, such as metals, semiconductors, silica, etc. We have been involved for a number of years in the rational design, synthesis and characterization of self-assembling proteins and peptides following identification of building blocks in viral fibers.
This previous work resulted in the identification of a minimal, octapeptide building block that self-assembles into fibrils, and these fibrils have recently been used as templates for the growth of inorganic materials. Controlled manipulation, positioning and nano-microfabrication of self-assembled protein and peptide materials remain a bigger challenge than their design and production. In collaboration with IESL colleagues, we have been using laser - fabricated scaffolds for their controlled positioning. These primary laser-fabricated scaffolds with attached secondary peptide scaffolds could then be used as a support for the directed growth of cells into
biomineralized units.
I will describe how structural insight and basic biochemical studies, combined with practical integration approaches, can result in materials applications ranging from the nano- to the macro-scale.

Abstract
Molecular switches in the genesis of pathogenic PrP: methionilsulfoxides and their models

Prion disorders are dominant gain-of-function neurodegenerations whose pathogenesis is linked to misfolded forms of the cellular prion protein (PrPC), including the prion PrPSc and the neurotoxic CtmPrP (1-4). PrPSc is an aggregated and protease resistant β-sheet-enriched conformer of PrPC, which self-perpetuates by the templating the conversion of cell surface PrPC (1,4). In contrast, CtmPrP is an intracellular transmembrane form generated at the ER with neurotoxic properties (1,5,6).

The long-standing hypothesis of prion biology is that the distinct biological and physicochemical properties separating PrPC and PrPSc relate only to the conformational differences of the C-terminal domain, which adopts a major globular α-fold in PrPC and displays a high content of β-sheet structure in PrPSc (7,8). However, the populations of PrPC and PrPSc also differ in the redox state the methionines of Helix-3, suggesting a possible role for these residues in facilitating the structural change ADDIN EN.CITE

Abstract

Organic photovoltaics (OPVs) are among the most promising photovoltaic technologies for long term sustainable energy production. The
low-temperature solution processability allows for roll-to-roll mass production on flexible plastic substrates which is expected to lead to
a light-weight and low-cost energy production platform, particular attractive for off grid and small power consumer electronics applications. In this talk, I will briefly report our recent efforts on solution processable graphene (SPG) materials development and plasmonic device engineering to significantly enhance the performance and stability of OPVs.

SPG based materials have been utilized as various components in OPVs, including transparent electrodes, buffer and active layers. In particular, functionalized SPG derivatives, synthesized via efficient functionalization of graphene oxide (GO) using conventional chemical
modification routes, are utilized as the electron acceptor material or additive in OPVs. Highly transparent and conductive reduced GO (rGO)
films on solid and flexible substrates are utilized as the transparent electrodes. The electrodes are produced in situ, by laser assisted photothermal reduction of spin casted GO films. In the same way, doped GO films with tuned work-function are produced by photochlorination.
As a proof of concept, highly efficient OPVs, incorporating photochlorinated GO as the buffer layer material are successfully demonstrated, significantly outperforming the reference PEDOT:PSS and pristine GO devices.

In the second part of my talk, I will address recent advances in the rapidly developing field of plasmonic organic photovoltaics. NPs of
various sizes, shapes and configurations have been integrated into OPV cell architecture in order to tune and enhance, in a wavelength-dependent manner, the optical absorption of the respective devices. As a result impressive improvements in the respective device
efficiencies were achieved. Particular attention will be paid in our work on the incorporation of uncapped Au, Ag and Al NPs formed by ablation of metallic targets in liquids with pico- and femtosecond laser pulses in the active layer leading to a significant enhancement in both device performance and lifetime

Abstract

The complete set of charge transfer parameters either between neighboring bases or between successive base pairs in DNA, considering
all possible combinations between them, is presented for both electrons and holes. These quantities can be used in theoretical models of electron or hole transfer along the DNA double helix, as they provide the necessary parameters for a phenomenological description based on the pi molecular overlap.
Relative reaction rates for hole transfer between G radical cations and GGG triplets in DNA, through different bridges of varying length, are numerically calculated and the obtained results are compared with corresponding experimental observations. Hole donors and acceptors are
separated either by (T-A)_n bridges or by N repeated barriers consisting of (T-A,T-A) double base-pairs which are connected through single G-C base-pairs. In the former case, hole transfer rates show a strong exponential decrease with the length of the bridge for short bridges, while a switching to weak distance dependence has been observed for longer bridges. In the latter case, a power law seems to better describe the distance dependence of charge transfer rates. All these experimental observations are qualitatively reproduced by our simulations without any adjustable parameter. Physical insights for the mechanism providing the switching behavior in the case of (T-A)_n bridges are presented through an analysis of the eigenfuctions of the system.
