The bi-conductive surfaces have a periodic arrangement of low-conductivity material embedded within a high-conductivity substrate. The thermal conductivity of the epoxy (<1 W/mK) is several orders of magnitude less than that of copper (~400 W/mK). When submerged in a fluid and heated from the underside, this creates an in-plane variation in surface temperature. Due to the extreme conductivity difference, there is negligible heat conducted through the epoxy divisions during nucleate boiling (see thermal circuit analysis in the Supplementary Material). As such, the wall superheat temperature above the epoxy divisions will be notably reduced as compared to that experienced over the copper sections. At low average wall superheats, prior to bubble nucleation, these in-plane temperature variations will drive natural convection flows aligned with the epoxy divisions similar to Rayleigh-Bérnard convection rolls. It has been shown that this sort of flow instability is immediately triggered for any finite superheating with a spatially varying surface temperature27. The resulting flow-field draws cooler liquid down toward the surface from above the epoxy divisions, while warmer fluid rises from above the hot copper. At these early stages the counter-rotating flows will produce a stagnation point in the center of the copper, resulting in a local minimum in convective heat transfer coefficient and therefore a local maximum in surface temperature28. As the wall superheat is increased this local maximum temperature promotes bubble nucleation along the center of the copper regions. This results in the formation of an ordered flow-field, as shown schematically in Fig. 1e, which persists at increasing thermal loadings. The in-plane variations in wall superheat take a periodic form with a wavelength equal to the pitch between epoxy divisions, P. This superheat wavelength dictates the nature and location of the ordered pathways of escaping vapor and replenishing liquid returning to the surface during nucleate boiling. Figure 1f shows an image of the onset of nucleate boiling, where the first few nucleation sites are activated on a bi-conductive surface (N = 4 cm−1) at a wall superheat of ~5 K. As can be seen, the vapor bubbles preferentially nucleate near the center of the copper due to the local maximum in surface temperature. This is consistently seen for all of the surfaces tested, and demonstrates that the wettability of the epoxy is not promoting nucleation due to a lower surface energy (see supplemental movies). Additionally, Fig. 1g shows how the superheat wavelength, P, imparts a level of control over the bubble diameter during lateral coalescence. By ordering nucleation sites and liquid return pathways, the size of bubbles undergoing lateral coalescence across an epoxy division is tuned to nominally coincide with the superheat wavelength, P.

“I went with poplar on the parts that are going to have the most human contact (legs, top and outside skirt, because pine is so dang soft”–that’s a good thought, but depending on the pine species, poplar isn’t necessarily harder (http://tinytimbers.com/janka.htm).

where Cpl is the heat capacity of the liquid and hfg is the latent heat of vaporization29. Evaluating equations (6) and (7) for saturated water on copper results in values of  = 1.04 ± 0.1 and  = 0.98 ± 0.1, respectively, considering the uncertainties in contact angle and material properties. The bubble departure diameters predicted by both models closely match the optimal pitch between epoxy divisions found experimentally to be  ≈ 1.

Once the completed shell is removed by the operator, the hydraulic mold closes up, the melted Lexan is pumped in and pressure and heat creates another shell.

Boral TruExterior trim and siding material is made of fly ash, a byproduct of burning coal, along with a proprietary blend of polymers. According to Boral, it is nearly impervious to moisture and termites, and is suitable for ground and masonry contact. What that means, essentially, is that many of the accommodations that builders make to keep wood siding safe from rot—such as leaving gaps where the siding runs into rooflines or horizontal surfaces—don’t apply to this product. If it does what they say it does, there’s a lot to like. Time will tell.

Now, consider the alternatives. By paying just Rs 1,000 more (in comparison to the 64GB storage variant of the 8C), you can get Xiaomi Redmi Note 6 Pro, which beats the Honor 8C in every single way imaginable. Then there’s the Asus Zenfone Max Pro M1, which offers near-stock Android, a higher-resolution display, and an even bigger battery, all at the same price as the 8C.

The rest of the case is great. Buttons are clicky and easy to press, there’s a nice lip around the camera to prevent it from getting damaged, and the fingerprint sensor cutout slopes down to meet the sensor perfectly. The front lip is higher than a glass screen protector, should you choose to use one. There’s a bit of branding (the ‘Spigen’ on the back and the ‘Neo Hybrid’ on the frame), but it’s pretty subtle.

That afternoon, he was eating salmon sashimi, and complaining about seasonal allergies. “I’m going to limp toward the weekend, and take Monday off, I think,” he said. He described the previous day as “momentous.” His iPhone 6 softly chimed a text alert every minute or two. To those of Ive’s generation, the new phones were perhaps large and slippery enough to trigger nostalgia for the small, tough phones of a decade ago. I asked Ive about the slightly protruding camera lens that prevents the iPhone 6 from resting comfortably on its back. Ive referred to that decision—without which the phone would be slightly thicker—as “a really very pragmatic optimization.” One had to guess at the drama behind the phrase. “And, yeah . . .” he said.
