Abstract. This paper reports on the extremely superhydrophobic behavior of supercritical CO 2 processed silicon nanowires SiNWs) with a contact angle in excess of ∼177°. …

On superhydrophobic surfaces (hot-embossed xPTFE), the elastic drops move at a significantly reduced rate (up to ∼85% reduction). "Branch-like" structures were left behind the drop and a "beads-on-tail" instability forms on that tail. Thus significant fluid residue is left on surfaces which are nominally "non-wetting".

Bio-inspired anti-wetting surfaces, such as lotus leaf or pitcher plant, have led to the development of stable liquid infused slippery surfaces for various scientific applications. The present ...

Fig. 1 shows the SEM images of bare aluminum and as-prepared superhydrophobic surfaces at different magnifications. The aluminum surface is relatively smooth after sanding, as shown in Fig. 1 a. The Cu-assisted chemically etched foils shown in Fig. 1 c illustrates the formation of irregular 5–10 μm particles and ball-like grains with 8 …

Self-folding microscale origami patterns are demonstrated in polymer films with control over mountain/valley assignments and fold angles using trilayers of photo-crosslinkable copolymers with a temperature-sensitive hydrogel as the middle layer. The characteristic size scale of the folds W = 30 μm and figure of merit A/ W 2 ≈ 5000, …

Fig. 3 depicts an iCVD deposition in a generalized reactor and Fig. 4 shows the overall chemical mechanism. A monomer species (M) and an initiator species (I 2) flow simultaneously into the reactor.The monomer passes through the heated filament zone with no ill effects and conformally adsorbs to the substrate surface, which is maintained at low …

S/I Bico fiber One type of bicomponent fiber is S/I Bico Fiber, whereby several fibrils of one polymer are distributed in another polymer's matrix. Fibrils are referred to as islands and the sea is the matrix [12]. Within the industry, the existing standard is 37 islands per filament, while construction with up to 91 islands is possible at

MIT's Department of Mechanical Engineering (MechE) offers a world-class education that combines thorough analysis with hands-on discovery. One of the original six courses offered when MIT was founded in 1865, MechE's faculty and students conduct research that pushes boundaries and provides creative solutions for the world's problems.

A green process to prepare the hydrophobic and transparent CNT-based surface was developed without using any toxic chemicals, solvents or gases. CNT brush (CNT-b) powder, which was prepared by the repeated CVD, was the main material to prepare the desired surface. An adhesive layer of ethyl cellulose (EC) was spin coated on the glass …

Each node in the tree represents a subset of these points. Instead of storing all points as individual objects, only the number of points, the sum and the squared sum of the subset's points are stored as key features of each subset.
