Supramolecular self-assembly based on noncovalent interactions is considered as a key strategy for introducing intracellular synthetic biocompatible macromolecules. The synthetic macromolecules resemble the nature, behavior, and function of biomacromolecules in living systems.
Metal-organic frameworks (MOFs) bring tremendous opportunities for separation of liquid chemicals using membranes.
Characterized by large aperture and long focal length, the reflective optical system has the advantages of small number of optical elements and simple optical structure. But the intrinsic aberration and the misalignment derived aberration increase exponentially with the increase of focal length and aperture, resulting in a significant degradation of the optical system imaging quality caused by just a small amount of misalignment.
In the enduring dryness of the Atacama Desert in northern Chile where the average rainfall is as low as 5 millimeters per year, rare rain events can come swiftly and intensely. They shape the landscape and provide precious moisture to plants and other species that otherwise adapted to extended dry spells or harvesting coastal fog. Intense rain events like those seen in the Atacama are known to be associated with so-called moisture conveyor belts, which are high-altitude atmospheric phenomena known for transporting large volumes of water vapor. However, whether or not moisture conveyor belts are responsible for the Atacama's intense rain events has yet to be shown.
Climate change will limit where the Winter Olympics can be held as winter changes across the Northern Hemisphere, according to a study by an international team of researchers led by the University of Waterloo.
The wettability of a surface—whether drops of water or another liquid bead up or spread out when they come into contact with it—is a crucial factor in a wide variety of commercial and industrial applications, such as how efficiently boilers and condensers work in power plants or how heat pipes funnel heat away in industrial processes. This characteristic has long been seen as a fixed property of a given pair of liquid and solid materials, but now MIT researchers have developed a way of making even the most unlikely pairings of materials take on a desired level of wettability.
