Static and dynamic properties of poly(3-hexylthiophene) films at liquid/vacuum interfaces.

The Journal of chemical physics

Yimer YY, Tsige M.
PMID: 23206021
J Chem Phys. 2012 Nov 28;137(20):204701. doi: 10.1063/1.4767395.

All-atom molecular dynamics simulations are used to study static and dynamic properties of poly(3-hexylthiophene) (P3HT) films at liquid/vacuum interfaces with regards to their dependence on both temperature and molecular weight. The static properties of the films are characterized by...

Epitaxial transfer through end-group coordination modulates the odd-even effect in an alkanethiol monolayer assembly.

Nanoscale

Yimer YY, Jha KC, Tsige M.
PMID: 24553572
Nanoscale. 2014 Apr 07;6(7):3496-502. doi: 10.1039/c3nr05671f.

Short spacer length and high end-group coordination lead to the top network acting as a template for the buried sulfur-gold interface of n-alkanethiols (SH-(CH2)n-OH or SH-(CH2)n-CH3) on gold {111}. Annealing and templating both drive toward a higher sampling of...

Assessment of molecular dynamics simulations for amorphous poly(3-hexylthiophene) using neutron and X-ray scattering experiments.

Soft matter

Wolf CM, Kanekal KH, Yimer YY, Tyagi M, Omar-Diallo S, Pakhnyuk V, Luscombe CK, Pfaendtner J, Pozzo LD.
PMID: 31183486
Soft Matter. 2019 Jun 26;15(25):5067-5083. doi: 10.1039/c9sm00807a.

The molecular morphology and dynamics of conjugated polymers in the bulk solid state play a significant role in determining macroscopic charge transport properties. To understand this relationship, molecular dynamics (MD) simulations and quantum mechanical calculations are used to evaluate...

Positive Murphy's Sign in Pericardial Hematoma from a Right Atrial Tear.

Cureus

Sridhara S, Lichtenwalter C, Mazdeh S, Yeneneh BT.
PMID: 30533336
Cureus. 2018 Oct 02;10(10):e3402. doi: 10.7759/cureus.3402.

A positive Murphy's sign in a patient with right upper quadrant abdominal pain is the arrest of inspiration during deep palpation of the quadrant. It is usually suggestive of acute cholecystitis. We report an unusual case of a positive...

We present a case of refractory acute hypoxemic respiratory failure due to influenza B pneumonia with concomitant large intra-atrial shunt (IAS) and severe pulmonary regurgitation in a patient with Saethre-Chotzen syndrome with prior pulmonary homograft placement. Our patient's hypoxemia...

LK peptide side chain dynamics at interfaces are independent of secondary structure.

Physical chemistry chemical physics : PCCP

Donovan MA, Lutz H, Yimer YY, Pfaendtner J, Bonn M, Weidner T.
PMID: 29043310
Phys Chem Chem Phys. 2017 Nov 01;19(42):28507-28511. doi: 10.1039/c7cp05897g.

Protein side chain dynamics are critical for specific protein binding to surfaces and protein-driven surface manipulation. At the same time, it is highly challenging to probe side chain motions specifically at interfaces. One important open question is the degree...
