The engineering properties of clayey soils, including fluid permeability, erosion resistance and cohesive strength, are quite different from those of non-cohesive soils. This is mainly due to their small platy particle shape and the surrounding diffuse double layer structure.

Soiling particle interactions on PV modules: Surface and inter-particle adhesion and chemistry effects Abstract: The understanding of the fundamental physics and chemistry of dust and the interaction of these soiling fragments with the PV module surface and each other is potentially important to developing viable mitigation approaches. This paper builds on our previous reports and observations investigating individual soiling particle adhesion on PV module glass using microscale proximal probe techniques. Specifically, in this presentation we report on the refinement of those adhesive force measurements by gaining and including information on the contact area of those particles with the surface, the specific chemistry of interactive surfaces, and the quantification of the force values using materials standard.

Van der Waals and electrostatic interactions are the dominant forces acting at the nanoscale and they have been reported to directly influence a range of phenomena including surface adhesion, friction, and colloid stability but their contribution on nanoparticle diffusion dynamics is still not clear. In this study we evaluated experimentally the changes in the diffusion coefficient of nanoparticles as a result of varying the magnitude of Van der Waals and electrostatic forces.

The rate at which colloidal particles can form biomolecular bonds controls the kinetics of applications such as particle-based biosensing, targeted drug delivery and directed colloidal assembly. Here we study how the reactivity of the particle surface depends on its molecular composition, quantified by the inter-particle rate of aggregation in an optomagnetic cluster experiment. Particles were functionalized with DNA or with proteins for specific binding, and with polyethylene glycol as a passive surface crowder. The data show that the inter-particle binding kinetics are dominated by specific interactions, which surprisingly can be tuned by the passive crowder molecules for both the DNA and the protein system. The experimental results are interpreted using model simulations, which show that the crowder-induced decrease of the particle surface reactivity can be described as a reduced reactivity of the specific binder molecules on the particle surface.

In phytosynthesis of gold nanoparticles AuNPs , biomolecules play a vital role in biocapping the surface of particles and generating the electrostatic repulsive forces to inhibit their growth kinetics. The quantitative estimation of interparticle interactions and modification in Ostwald ripening MOR model were also done to correlate the growth kinetic of AuNPs. The X-ray photoelectron spectroscopy XPS showed the major contribution of oxygen, carbon and nitrogen elements, corresponding to polyphenolic, carboxylic and amides, in biocapping the surface of AuNPs and directing their interparticle interactions associated with growth kinetics. The MOR model exhibited an excellent agreement of predicted growth with experimental size enlargements of AuNPs, having 4.

Она чувствовала, как к ее горлу подступает тошнота. Его руки двигались по ее груди. Сьюзан ничего не чувствовала.

По мере того как они удалялись от двери, свет становился все более тусклым, и вскоре они оказались в полной темноте. Единственным освещением в шифровалке был разве что свет звезд над их головами, едва уловимое свечение проникало также сквозь разбитую стеклянную стену Третьего узла. Стратмор шагнул вперед, нащупывая ногой место, где начинались ступеньки узенькой лестницы. Переложив берет-ту в левую руку, правой он взялся за перила. Он прекрасно знал, что левой рукой стрелял так же плохо, как и правой, к тому же правая рука была ему нужна, чтобы поддерживать равновесие.

 Тяжелая неделя? - спросила. - Не тяжелей, чем обычно.  - Стратмор пожал плечами.  - Фонд электронных границ замучил неприкосновенностью частной жизни и переписки. Сьюзан хмыкнула.

Стол, накрытый стеклом, и черный кожаный стул были расположены прямо перед громадным венецианским окном. Три шкафа-картотеки стояли в углу рядом с маленьким столиком с французской кофеваркой. Над Форт-Мидом высоко в небе сияла луна, и серебристый свет падал в окно, лишь подчеркивая спартанскую меблировку. Что же я делаю. - подумал Бринкерхофф. Мидж подошла к принтеру и, забрав распечатку очередности задач, попыталась просмотреть ее в темноте.

Мощенный брусчаткой тротуар под ногами постепенно сливался в одну темную гладкую полосу. Быстро опускалась ночь. Капля Росы.

Вот. На ступенях прямо перед Халохотом сверкнул какой-то металлический предмет.
