Strengthening the thermal response of Phase-Change Materials (PCMs) is an essential and active field research with promising potential for advanced applications such as solar energy storage, building conservation, management in electronic devices. This article evaluates efficacy a new arc-shaped fin array shell-and-tube heat storage systems to enhance PCM during discharge mode. Different geomet...

In this work, we report an optofluidic system for manipulation of orientation zeolite crystals near the bottom a rectangular cross-sectional, straight, quartz microfluidic channel. Manipulation is accomplished by using two computer-controlled syringe pumps that generate adequate hydrodynamic forces translation and rotation crystals. Rotation crystal around its longitudinal axis allows us to ins...

Line-tension-induced scenario of heterogeneous nucleation is studied for a lens-shaped nucleus with a finite contact angle nucleated on a spherical substrate and on the bottom of the wall of a spherical cavity. The effect of line tension on the free energy of a critical nucleus can be separated from the usual volume term. By comparing the free energy of a lens-shaped critical nucleus of a finit...

Bottom center drain circular tanks in which water is injected tangentially to the tank wall are widely used aquaculture. However, a torus-shaped region about can develop into an irrotational zone that generates low velocities and poor mixing. Many works have been devoted improving hydraulics by making good use of flow pattern. mathematics-friendly methods, such as statistical optimization metho...

Large-scale, deterministic assembly of nanowires and nanotubes with rationally controlled geometries could expand the potential applications of one-dimensional nanomaterials in bottom-up integrated nanodevice arrays and circuits. Control of the positions of straight nanowires and nanotubes has been achieved using several assembly methods, although simultaneous control of position and geometry h...

The use of delivery templates makes it possible to fabricate shaped, millimeter-thick heterogeneously patterned films of ionotropic hydrogels. These structures include two-dimensional (2-D) patterns of a polymer cross-linked by different ions (e.g., alginic acid cross-linked with Ca2+ and Fe3+) and patterns of step gradients in the concentration of a single cross-linking ion. The delivery templ...

Antigen-combining site arises by noncovalent association of the variable domain of the immunoglobulin heavy chain (VH) with that of the light chain (VL). To analyze the invariant features of the binding region (VL-VH domain interface), we compared the known immunoglobulin three-dimensional structures by a variety of methods. The interface forms a close-packed, twisted, prism-shaped "beta-barrel...

Self-assembly processes and subsequent photo-cross-linking were used to generate cross-linked, ordered microporous structures on the surfaces of well defined four-arm star-shaped poly(D,L-lactide) (PDLLA) thin films. The four-arm star-shaped PDLLAs were synthesized using an ethoxylated pentaerythritol initiator. Solutions of the PDLLAs were cast in a humid environment, and upon solvent evaporat...

In terrestrial vertebrates, the pelvic girdle can reliably predict locomotor mode. Because of the diminished gravitational effects on positively buoyant bony fish, the same relationship does not appear to exist. However, within the negatively buoyant elasmobranch fishes, benthic batoids employ pelvic fin bottom-walking and punting as primary or supplementary forms of locomotion. Therefore, in t...
