Estimation of the solubility parameters of model plant surfaces and agrochemicals: a valuable tool for understanding plant surface interactions [PDF]

open access: yes, 2012
Background Most aerial plant parts are covered with a hydrophobic lipid-rich cuticle, which is the interface between the plant organs and the surrounding environment.

Electro-osmotic flow in coated nanocapillaries: a theoretical investigation

open access: yes, 2014
Motivated by recent experiments, we present a theoretical investigation of how the electro-osmotic flow occurring in a capillary is modified when its charged surfaces are coated by charged polymers.

The Large Magellanic Cloud as a laboratory for Hot Bottom Burning in massive Asymptotic Giant Branch stars [PDF]

open access: yes, 2015
We use Spitzer observations of the rich population of Asymptotic Giant Branch stars in the Large Magellanic Cloud (LMC) to test models describing the internal structure and nucleosynthesis of the most massive of these stars, i.e.

Detachment, Futile Cycling and Nucleotide Pocket Collapse in Myosin-V Stepping

open access: yes, 2015
Myosin-V is a highly processive dimeric protein that walks with 36nm steps along actin tracks, powered by coordinated ATP hydrolysis reactions in the two myosin heads.

Explicit schemes for time propagating many-body wavefunctions [PDF]

open access: yes, 2014
Accurate theoretical data on many time-dependent processes in atomic and molecular physics and in chemistry require the direct numerical solution of the time-dependent Schr\"odinger equation, thereby motivating the development of very efficient time ...

The Effect of an Inert Solid Reservoir on Molecular Abundances in Dense Interstellar Clouds

open access: yes, 2012
The question, what is the role of freeze-out of chemical species in determining the molecular abundances in the interstellar gas is a matter of debate.

Educational activities for physical pharmacy classes on colloids [PDF]

open access: yes, 2021
Colloids are an important component of physical chemistry and physical pharmacy curricula. In pharmacy, colloidal systems and concepts are encountered in dosage forms (e.g., suspensions, emulsions) and many drug delivery systems (e.g., nanoparticles ...

How does an interacting many-body system tunnel through a potential barrier to open space? [PDF]

open access: yes, 2012
The tunneling process in a many-body system is a phenomenon which lies at the very heart of quantum mechanics. It appears in nature in the form of alpha-decay, fusion and fission in nuclear physics, photoassociation and photodissociation in biology and ...
