What Happened to Google Maps?

by manishs
Google Maps has reduced the number of cities it shows by up to 83% over the past few years, according to Justin O'Beirne. Maps, in addition, has increased the number of roads it showcases. O'Beirne, who writes about digital maps, in a blog post outlines the changes Google has made to its mapping and navigation service over the years. The side-by-side screenshots comparison on his blog post shows that Google has largely abandoned labelling towns and cities in favor of showing as many roads as it can. He has also looked into several elements of Maps from the design standpoint, and questioned Google's decision. He writes: If these roads were so important that they deserved to be upgraded in appearance, why weren't they also given shield icons? After all, an unlabeled road is only half as useful as a labeled one. [...] [Comparing Google Maps to a paper map] Even though it's from the early 1960s, the old print map has so much more information than the Google Map. So many more cities. So many more road labels. And the text size is comparable between the two. O'Beirne believes that Google has made these changes to better serve mobile users. "Unfortunately, these 'optimizations' only served to exacerbate the longstanding imbalances already in the maps," he writes. "As is often the case with cartography: less isn't more. Less is just less."

Nitrogen-Doped Porous Carbon Nanosheets Templated from g-C3N4 as Metal-Free Electrocatalysts for Efficient Oxygen Reduction Reaction

by Huijun Yu, Lu Shang, Tong Bian, Run Shi, Geoffrey I. N. Waterhouse, Yufei Zhao, Chao Zhou, Li-Zhu Wu, Chen-Ho Tung, Tierui Zhang
Thumbnail image of graphical abstract

Nitrogen-doped porous carbon nanosheets (N-CNS) are synthesized by hydrothermal carbon coating of g-C3N4 nanosheets followed by high-temperature treatment in N2. g-C3N4 serves as a template, nitrogen source, and porogen in the synthesis. This approach yields N-CNS with a high nitrogen content and comparable oxygen reduction reaction catalytic activities to commercial Pt/C catalysts in alkaline media.

A Butcher’s Six Secrets for Saving Money on Meat

by Adam Danforth

When I think about thrift and meat—specifically in the U.S., but increasingly in areas like Europe—the first thing that comes to mind is the devotion folks have to tenderness. This tends to be the Holy Grail quality people look for in meat. To me, this is a backwards approach to quantifying the quality of meat.

Synthesis of Cyclooctatetraenes through a Palladium-Catalyzed Cascade Reaction

by Sarah Blouin, Vincent Gandon, Gaëlle Blond, Jean Suffert

Abstract

Reported is a cascade reaction leading to fully substituted cyclooctatetraenes. This unexpected transformation likely proceeds through a unique 8π electrocyclization reaction of a trienyne. DFT computations provide the mechanistic basis of this surprizing reaction.

Low-Overpotential Electrocatalytic Water Splitting with Noble-Metal-Free Nanoparticles Supported in a sp3 N-Rich Flexible COF

by Dinesh Mullangi, Vishal Dhavale, Sorout Shalini, Shyamapada Nandi, Sean Collins, Tom Woo, Sreekumar Kurungot, Ramanathan Vaidhyanathan

Covalent organic frameworks (COFs) are crystalline organic polymers with tunable structures. Here, a COF is prepared using building units with highly flexible tetrahedral sp3 nitrogens. This flexibility gives rise to structural changes which generate mesopores capable of confining very small (<2 nm sized) non-noble-metal-based nanoparticles (NPs). This nanocomposite shows exceptional activity toward the oxygen-evolution reaction from alkaline water with an overpotential of 258 mV at a current density of 10 mA cm−2. The overpotential observed in the COF-nanoparticle system is the best in class, and is close to the current record of ≈200 mV for any noble-metal-free electrocatalytic water splitting system—the Fe–Co–Ni metal-oxide-film system. Also, it possesses outstanding kinetics (Tafel slope of 38.9 mV dec−1) for the reaction. The COF is able to stabilize such small-sized NP in the absence of any capping agent because of the COF–Ni(OH)2 interactions arising from the N-rich backbone of the COF. Density-functional-theory modeling of the interaction between the hexagonal Ni(OH)2 nanosheets and the COF shows that in the most favorable configuration the Ni(OH)2 nanosheets are sandwiched between the sp3 nitrogens of the adjacent COF layers and this can be crucial to maximizing their synergistic interactions.

A highly flexible sp3 N-rich covalent organic framework (COF) as support for M/M(OH)2 (M = Ni/Co) nanoparticles to form electrocatalysts for water splitting with exceptionally low overpotentials (258 mV @ 10 mA cm−2) and favorable electrode–electrolyte kinetics (Tafel slope = 38.9 mV dec−1) is developed. The synergistic interactions between sp3 nitrogens of the COF and the nanoparticle are evident from density-functional-theory modeling.
