TL;DR: In this paper, the authors present an overview of various cooling methods that can be employed for photovoltaic cells, including linear concentrators, single-cell arrangements, and densely packed photovolastic cells.

TL;DR: In this article, direct force measurements on a broad class of hydrophobic and hydrophilic surfaces have enabled the development of a general interaction potential per unit area, W(D) = −2γiHy exp(−D/DH).

TL;DR: In this paper, a cooling device based on jet impingement is proposed for cooling of densely packed photovoltaic cells under high concentration, which consists of an array of jets where the cooling fluid is drained around the sides in the direction normal to the surface.

TL;DR: In this article, a microstructurally consistent, self-propagating fracture mechanism was proposed, driven by the growth and transformation of a metastable amorphous proto-serpentine phase, where stress is localized within surface perturbations (etch pits and coalesced etch pits).

TL;DR: In this article, the observed spheroidal weathering patterns in basaltic intrusions (dolerites) in the Karoo Basin in South Africa are created through volume expanding reactions which set up stresses that not only lead to spalling of spheroroidal layers of rock, but also drive a large scale hierarchical fracturing process by which the dolerite is continuously undergoing domain division.
