Nearly 20 years after its introduction, the iPod Nano is still a perfectly functional music player.

Bird feathers are finely tuned structures with key features at every length scale, from nanometre to metre, furnishing a unique multi-functional hierarchical design that can inspire material scientists, biologists and designers alike. Feathers are not ...

Realizing tunable functional materials with built-in nanoscale heat flow directionality represents a significant challenge that could advance thermal management strategies. Here we use spatiotemporally resolved thermoreflectance to visualize lateral thermal transport anisotropy in self-assembled supercrystals of anisotropic Au nanocrystals. Correlative electron and thermoreflectance microscopy reveal that nano- to mesoscale heat predominantly flows along the long-axis of the anisotropic nanocrystals, and does so across grain boundaries and curved assemblies while voids disrupt heat flow. We finely control the anisotropy via the aspect ratio of constituent nanorods, and it exceeds the aspect ratio for nanobipyramid supercrystals and certain nanorod arrangements. Finite element simulations and effective medium modeling rationalize the emergent anisotropic behavior in terms of a simple series resistance model, further providing a framework for estimating thermal anisotropy as a function of material and structural parameters. Self-assembly of colloidal nanocrystals promises an interesting route to direct heat flow in a wide range of applications that utilize this important class of materials.

Meet the pico-mac-nano, a super tiny yet functional Macintosh replica created by 1-bit rainbow, a website that sells parts for vintage Apple products. Inside the miniature 3D-printed Macintosh 128K case is a small Raspberry Pi Pico computer board, along with a 2-inch LCD screen. The replica Macintosh is actually usable, as it runs an emulated version of the classic Mac operating system, and it has USB keyboard and mouse support with an included USB splitter cable. 1-bit rainbow is selling the pico-mac-nano for £56, but it has gone out of stock after it received attention on tech blogs. The website says orders will resume "soon," and you can enter your email to be notified. Or, you could create one yourself, as the pico-mac code and 3D-printable case files are freely available on GitHub. 1-bit rainbow's Nick Gillard shared more details about the pico-mac-nano in a blog post.Tag: Macintosh This article, "This Tiny Macintosh Replica Actually Works" first appeared on MacRumors.com Discuss this article in our forums
