寻找新的2D材料以使电池更好,更便宜

“美国国家科学基金会向芝加哥伊利诺伊大学提供了144万美元的赠款,用于发现可用于制造大大改进且更便宜的电池的新型二维(2D)材料。石墨烯是2D材料中最常见的一种,它是一种非常坚固,灵活,轻巧且极佳的电和热导体。它比纸薄一百万倍,几乎是透明的,据说是世界上最坚固的材料。

继2004年发现石墨烯后,预计约有700种2D材料是稳定的。许多仍有待制造。预计全球二维材料市场将在10年内达到3.9亿美元。

希望提高2D材料的性能(他们相信二硫化钼是电池的潜在候选材料),还希望了解它们的功能。希望找到可以显着而不是逐步提高电池效率的新型催化剂材料。我们相信,与现有材料相比,新材料可将其电化学反应性能提高约1,000倍。这将是革命性的。

研究将在2D材料中添加离子液体,以刺激电化学反应,该电化学反应可用于产生可持续的能量,存储能量,制造化学物质并清除地下水,土壤,沉积物或地表水中的污染或污染物。在能量存储和转换设备(例如高级电池,燃料电池,光伏电池和化学电解槽)中使用的电催化正成为常规热催化的一种越来越重要的替代方法。但是,在将其商业化销售之前,需要在效率,降低成本和化学选择性方面进行进一步的改进。这些电池可以以多种方式使用-从操作汽车到需要时产生应急电源。该技术最终可以用于电网,从生产者向消费者供电。”

Hands on: Beats PowerBeats Pro review

In May, Uber launched a new experiment: selling train and bus tickets through its app for its customers in Denver, Colorado. Today, the company reports that it has sold over 1,200 tickets for the city’s Regional Transportation District, which operates Denver’s public transportation system.

THE COMPANY REPORTS GROWTH AVERAGING 42 PERCENT EACH WEEK DURING THE ROLLOUT PERIOD

Uber Transit, the company’s in-app ticketing feature, was made available to a small cohort of customers in May, and it has since become available to 100 percent of Uber users in Denver as of June 25th. The company reports growth averaging 42 percent each week during the rollout period.

Uber may not make any money when it sells bus and subway tickets through its app, but it is seeing an uptick in business as a result. Since Uber launched its transit planning feature in January, Uber trips in Denver that start or end at a transit station have grown 11.6 percent. This helps bolster Uber’s claim that it is helping solve the first mile / last mile challenge that plagues many cities.

Uber also said that the number of repeat ticket purchases has increased every week since ticketing launched. As of the week of June 24th, approximately 25 percent of tickets sold were purchased by users who had previously purchased tickets on the app.

Uber’s new transit feature is powered by Masabi, a London-based tech company that builds mobile ticketing software for public transportation. This is the first incarnation of Uber and Masabi’s partnership since the two companies first struck a deal last year to integrate the latter’s mobile ticketing platform into the former’s app. Uber riders in Denver have been able to see real-time bus and rail information when they open the app since January, courtesy of transit data firm Moovit.

For now, Uber is taking its first foray into public transportation slowly, one city at a time. So far, the company offers real-time subway and bus schedules, time and cost comparisons, and point-to-point directions for customers in London and Boston. It most likely will launch ticket purchasing in those cities later this year.
