Lithium from the coal in China: Extracting lithium metal from Chinese coal.

Coal from China could become a major source of the metal lithium, according to a review of the geochemistry by scientists published in the International Journal of Oil, Gas and Coal Technology.

Lithium is an essential component of used almost ubiquitously in mobile gadgets such as phones, laptops, tablet computers and in many electric vehicles. Worldwide annual consumption of this metal grew from 15100 tonnes in 2003 to 37000 tonnes by 2012, a 145 percent increase and demand is expected to rise even further as we move more towards sustainable power and electrical storage capacity increases.更多信息请注意浏览原文。

Abstract: Coals are a major source of pollution in certain parts of the world due to mining, coal combustion, and disposal of fly ash. The recovery of valuable rare metals from coals or coal-processing byproducts is a promising way to utilise these traditional resources economically, efficiently and in an environmentally friendly way. Lithium, a highly interesting metal, has been found dispersed and even anomalously enriched in coal deposits, and is potentially extractable. This paper presents a review of geochemical investigations on Li-bearing coal and the technical development of Li extraction from coal. Based on available literature, inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma as an excitation source (ICP-AES) are regarded as the preferred methods of measuring Li concentration in coal and coal ash. Anomalous Li accumulations have been reported in coal deposits, especially in China. The limited studies on Li modes of occurrence and origins are discussed, and Li is shown to have an affinity mainly for clay minerals in coal, although further investigations are needed. Lithium is also found to be enriched in fly and bottom ashes during coal combustion. Finally, two successful Li recovery techniques from coal ash are presented.

Nanotechnology news

Caging of molecules allows investigation of equilibrium thermodynamics

High performance materials for gas storage, thermal insulators or nanomachines need a thorough understanding of the behavior of the material down to the molecular level. Thermodynamics, which have been developed two hundred years ago to increase the efficiency of steam engines, typically observes and averages over a large number of molecules. Now a team of scientists has developed a methodology, to investigate the equilibrium thermodynamics of single molecules.

Technology news

Smart bottles make use of printed sensor tags

You're looking at a commercial future where vendors will seek to leverage new technologies to track customer behavior, buying patterns, user patterns and to send out information realtime, up close, personal, as never before possible. What if your bottle of Johnnie Walker bottle, for example, turned "smart" and helped to suggest cocktail recipes or promotional offers? That appears to be in the works and will be showcased next month. An NFC-enabled smart bottle was announced Wednesday and will be presented at the Mobile World Congress in Barcelona. Diageo—focused on drinks—and Thin Film Electronics ("Thinfilm")—focused on printed electronics—are teaming up to add something new to the role of the bottle. They have announced a prototype Johnnie Walker Blue Label "smart bottle." The prototype will be on display at Thinfilm's booth at the show.

Pebble turns to crowdfunding (again) for latest smartwatch

Palo Alto, California-based Pebble does, is still at it, the smartwatch pioneers still actively promoting an ability to produce an ideal smartwatch that people won't just like but love.

Research pair finds color a big factor in how much an image is shared on Pinterest

How do we mortals perceive random sequences? An entry in the question-and-answer site Quora focused on a question involving a music-streaming service Spotify. That question signifies how we perceive what is and what is not random.

Linguists tackle computational analysis of grammar

Children don't have to be told that "cat" and "cats" are variants of the same word—they pick it up just by listening. To a computer, though, they're as different as, well, cats and dogs. Yet it's computers that are assumed to be superior in detecting patterns and rules, not 4-year olds. John Goldsmith, the Edward Carson Waller Distinguished Service Professor of Linguistics and Computer Science, and graduate student Jackson Lee are trying to, if not to solve that puzzle definitively, at least provide the tools to do so.

New paper focuses on degree centrality in networks

Social networks such as Facebook, LinkedIn and Twitter play an increasingly central role in our lives. Centrality is also an important concept in the theory of social networks. Centrality of an individual, called a "node" in network theory, measures its relative importance within a network.

Social circles: Study details the degree to which urban movement is linked to social activity

Intelligent data analysis with guaranteed privacy

Siemens is developing tools that ensure smart data applications abide by data protection regulations. The reliable protection of data privacy is very important because it is a precondition for people or institutions to provide applications with personal data. In cooperation with the Fraunhofer Institute for Intelligent Analysis and Information Systems (Fraunhofer IAIS), the researchers at Siemens Corporate Technology (CT) are therefore creating a toolbox that helps users of smart data to adhere to the data protection regulations that apply to their applications. Although a great variety of algorithms exist for making data anonymous, many of them are not suited to the software environments that are typical of smart data. The new toolbox will contain a selection of algorithms for such environments.

Radar sensors support parking management

Siemens is researching the use of sensor networks in an advanced parking management solution that will hopefully counter the increasing parking space crisis in cities. The online magazine Pictures of the Future reports about this solution, which will be used this spring for the first time in a pilot project in Berlin. In this concept, sensor networks collect information about the parking situation in cities. The information is forwarded to the drivers in order to make it easier for them to find unoccupied parking spaces. In addition, the data is transmitted to a parking management center so that cities can intelligently manage their parking spaces.
