Modulation of Epigenetic Control by Advanced Molecular Tweezers

Chemistry – A European Journal, EarlyView.
Tailored dimeric molecular tweezers recognize the DNA‐binding part of Histone H4 and interrupt the essential histone‐DNA interaction. ABSTRACT This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics.

Computation of Energy Release Rates for Kinking Cracks based on Virtual Crack Closure Technique

, 2004
A numerical method based on the virtual crack closure technique (VCCT) [Rybicki and Kanninen (1977)] and in conjunction with the finite element (FE) method is presented to compute strain energy release rates for cracks that kink.

Membrane lipid metabolism as a regulatory frontier in neural crest biology: Roles for sphingolipids, cholesterol, and lipid rafts

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are multipotent, migratory stem‐like cells essential for vertebrate development that contribute broadly to many tissues including the craniofacial skeleton, peripheral nervous system, and pigment‐producing cells. Their development progresses through phases of induction, specification, delamination, migration, and ...

Interface crack kinking in composite materials

, 2015
The mechanisms and criterion for interface crack kinking in composite materials was investigated in this study. The theory of linear elastic fracture mechanics, particularly stress intensity factors, and crack tip opening displacement were used to ...

Advances in Design Strategy and Mechanism Insights for Alkaline Hydrogen Evolution Reaction: Multilevel Site Engineering and Structure–Activity Relationship

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review is about material design based on engineering multilevel sites from theoretical calculation and synthetic routes to mechanism, structure–activity relationship, challenges and perspectives for boosting hydrogen production in alkaline electrolyte. Electrolytic water splitting is a clean, carbon‐free method for producing green hydrogen and has

Existence of solutions to a regularized model of dynamic fracture [PDF]

, 2010
Existence and convergence results are proved for a regularized model of dynamic brittle fracture based on the Ambrosio–Tortorelli approximation. We show that the sequence of solutions to the time-discrete elastodynamics, proposed by Bourdin, Larsen ...

Strengthened inter‐chain π–π contacts in amorphous diketopyrrolopyrrole polymers for robust flexible organic thin‐film transistors

FlexMat, EarlyView.
Vinylene‐linked DPP polymers with expanded thiophene donors achieve strengthened interchain π‐π stacking in near‐amorphous films, enabling high charge mobility and outstanding mechanical stability for flexible organic thin‐film transistors. Abstract Flexible organic thin‐film transistors (OTFTs) based on multi‐vinylene‐linked diketopyrrolopyrrole (DPP)
