You Can Make Your Walls Look Like a Metro Station’s Ceiling | Colored Polycarbonate Sheet

The decals are designed by artists on a computer and printed on a single sheet. The decal is removed from the backing just like the decals I used to put on model airplanes when I was a kid — they’re soaked in hot water until the decal comes off.

The picture on the right was taken with our FLIR ONE Pro thermal imaging camera. It’s an infrared picture of the Pentium N4200 version (top) and the Core i7-8650U version both running the PassMark benchmark suite. The higher thermal load of the powerful Core processor is plainly obvious, as is the heat emanating from its fan vent. That’s the difference between a thermal design power of 6 watts and one of 15 watts.

Tetra Pak Artistry will include three effects: Tetra Pak Reflect to include holographic effects onto the package, Tetra Pak Metallized to create a metallic effect, and Tetra Pak Craft to give the package the natural look of bare paperboard with wood fibers. Tetra Pack is considering some additional effects, which at development stage. One of the offerings includes Tetra Pak Sculpt, an embossed surface texture for an innovative consumer experience. All the effects will be available for the majority of Tetra Pak package formats and will be offered to customers worldwide.

Bi-conductive surfaces were fabricated by embedding lines of a low-conductivity epoxy into a copper substrate. Copper sheets (1 mm thickness) were cut to size and grooves were machined into them using Wire Electrical Discharge Machining (EDM). The EDM wire thickness was 0.254 mm with a reported minimum spark gap of 0.381 mm ± 0.127 mm. The copper was then treated with an alkaline solution to produce an oxide layer with nano-scale surface roughness to promote adhesion between the copper and epoxy14. The surfaces were then coated with a non-conductive high-temperature two-part epoxy (Aremco 526N) filling all of the grooves. The epoxy was cured at 93 °C for 2 hours, followed by 163 °C for 12 hours to achieve a maximum strength bond. After curing, the surfaces were manually sanded with 200 grit sand paper until the bare copper between each epoxy division was exposed. The bare copper surfaces (with no epoxy divisions) were also sanded using the same method. The surfaces were finally cleaned with solvents and dried with N2.

While structured surfaces have been shown to greatly increase boiling heat transfer, the reliability of these approaches for real-world applications is in question due to a variety of factors. All structured surfaces are inherently susceptible to mechanical failure (breaking of the micro/nano-structures), as well as fouling and clogging over time. During boiling, any and all contaminants within the fluid will inevitably be drawn into the structures. This will lead to clogging and filling of the small micro/nano-scale voids, and thus a loss of enhancement19. Similarly, the robustness of extremely thin nanostructured coatings (≤1 μm) has not yet been demonstrated, leaving the potential for the coatings to be destroyed or altered over time via chemical reactions21. The use of low-surface-energy materials to promote nucleation at small superheats has been successfully demonstrated as well22,23,24,25, however these biphilic surfaces are prone to degradation of the thin non-wetting films. Additionally, they are not effective with all working fluids, in particular highly wetting fluids like FC-72. While doubly reentrant surfaces have been demonstrated to repel these highly wetting fluids26, their use in biphilic designs for boiling enhancement has not yet been demonstrated.

The next day, I visited Ive in his studio. The table previously covered with a flat cloth was now uncovered: it was a glass-topped Apple Watch display cabinet, accessible to staff from below, via a descending, motorized flap, like the ramp at the rear of a cargo plane. Ive has begun to work with Ahrendts, Apple’s senior vice-president of retail, on a redesign—as yet unannounced—of the Apple Stores. These new spaces will surely become a more natural setting for vitrines filled with gold (and perhaps less welcoming, at least in some corners, to tourists and truants). Apple had not, overnight, become an élite-oriented company—and it would sell seventy-five million iPhones in the final quarter of 2014, many of them in China—but I wondered how rational, and pure of purpose, one can make the design of a V.I.P. area. Ive later told me that he had overheard someone saying, “I’m not going to buy a watch if I can’t stand on carpet.”

The Range Rover Velar debuts the all-new Touch Pro Duo infotainment system, which is the latest infotainment system to be developed by Jaguar Land Rover. Touch Pro Duo features two high-definition 10-inch touchscreens that form the centerpiece of the beautifully minimalist cabin, and blends a futuristic, elegant feel with an intuitive, engaging interface and exceptional functionality1.

The front view shows that Xplore designed the tablet to primarily be used in landscape mode, but it also quickly snaps into landscape or even upside down mode if the tablet is turned. For hardware controls, there’s an unmarked physical Windows button in the bottom center of the face. Above the display is the camera, the ambient light sensor, as well as dual microphones. To the right of the screen are four small indicator lights and the unit’s fingerprint scanner.

This sleek, wallet-style leather case from Guardian looks and feels great in the hand. It features two slots, one for cash and one for cards. Underneath is a micro-suction patch, which works to keep the phone in place. An purposeful gap between the phone and case allows for easy earbud storage, a super-handy feature for travelers. The Guardian Leather Case nicely protects the corners of the iPhone from scratches and bumps, and the leather smells just as good as it looks. — George Tinari

Surfaces were characterized using a custom-built test set-up as previously reported by Rahman et al.14,19. The setup consists of a copper heater block with PTFE insulation embedded with two cartridge heaters allowing for a maximum power of 1,000 W. Five T-type thermocouples were inserted into the copper block equally spaced 6 mm apart with the top most thermocouple located directly beneath the sample. The temperature measurements were recorded using NI DAQ system, where the average heat flux in the copper block was calculated using Fourier’s conduction law. The sample surface temperature was calculated by considering all of the relevant thermal resistances between the surface and the top most thermocouple, as described. A polycarbonate chamber was used as the water bath; with an immersion heater and thermocouple probe maintaining saturated conditions and atmospheric pressure. Degassed, deionized water was used as the working fluid, and all tests were carried out up to CHF. Visualization of the boiling process was conducted at low heat fluxes using a Phantom V210 high-speed camera (Vision Research) recorded at 3,100 fps. The surfaces were initially maintained at saturated condition for 1 hour after which a small increment of heat flux (2 W/cm2 to 5 W/cm2) was applied to the surfaces until the nucleation was observed. Heat flux was further increased up to 20 W/cm2 until the visibility of bubble dynamics becomes difficult. The chamber heater was turned off to minimize the bulk fluid motion while capturing the movies, with all movies being recorded within one minute to maintain saturation conditions, as described by Mukherjee and Dhir30 and Son et al.38.

Tectum Direct-Attach acoustical panels provide sound absorption in the studios while maintaining the look and feel of the exposed structure.

I’ve probably purchased more cases from Spigen in my many years as a smartphone enthusiast than any other brand. I’m sure you know why: the company consistently offers quality products at reasonable prices. Quite a few of those cases I’ve purchased have been clear ones, as I like to protect my phones from drops but still want to see their designs. I’m usually pretty pleased, though this Liquid Crystal for the Pixel 2 XL has one slight flaw that might prevent you from purchasing it.
