2019 journal article

Competition between Exceptionally Long-Range Alkyl Sidechain Ordering and Backbone Ordering in Semiconducting Polymers and Its Impact on Electronic and Optoelectronic Properties

ADVANCED FUNCTIONAL MATERIALS, 29(5).

author keywords: molecular design; organic electronics; polymer crystals; semiconducting polymers; sidechains
TL;DR: The observed influence of ordering between the moieties implies that improved molecular design could produce synergistic rather than destructive ordering effects and should greatly improve the coherence length of backbone ordering and thereby improve electronic and optoelectronic properties such as charge transport and exciton diffusion lengths.

Impact of Substrate Characteristics on Stretchable Polymer Semiconductor Behavior

ACS APPLIED MATERIALS & INTERFACES, 11(3), 3280–3289.

By: T. Sun n, R. Song n, N. Balar n, P. Sen n, R. Kline* & . Brendan T. O'Connor

author keywords: stretchable electronics; polymer semiconductors; yield strain; deformability; adhesion energy
TL;DR: It is found that increasing the near-surface modulus of thePDMS and maintaining the PDMS in tension throughout the cyclic strain process promote plastic deformation over film wrinkling, highlighting the importance of neighboring elastomer characteristics on the ability to achieve stretchable polymer semiconductors.

A Numerical Study of Sensitivity Coefficients for a Model of Amyloid Precursor Protein and Tubulin-Associated Unit Protein Transport and Agglomeration in Neurons at the Onset of Alzheimer's Disease

JOURNAL OF BIOMECHANICAL ENGINEERING-TRANSACTIONS OF THE ASME, 141(3).

By: I. Kuznetsov & A. Kuznetsov

author keywords: neuron; axon; neurodegenerative disease; mathematical modeling; local sensitivity analysis
TL;DR: The results of this analysis suggest that in the beginning of AD the aggregation of amyloid-ß and misfolded tau protein have little effect on transport of APP and tau in the axon, which suggests that early effects of AD may be reversible. (via Semantic Scholar)

Zero-energy-state-oriented tunability of spin polarization in zigzag-edged bowtie-shaped graphene nanoflakes under an electric field

NANOTECHNOLOGY, 30(8).

author keywords: zero-energy state; graphene nanoflake; spin degeneracy; half-metallic state; spintronics
TL;DR: It is demonstrated that the spin degenerate semiconducting ground state can be lifted by the electric field and it is found that the number of zero-energy states ('the nullity') defined by the structural configuration determines the complexity and efficiency of the tunability of spin polarization.
