Despite supplying just over a third of global electricity generation, coal’s status as the most carbon-intensive fossil fuel is driving many countries to reevaluate the role that it plays in energy production and national economies.

In a new paper, published in Communications Engineering, researchers suggest that coal could continue to be used to power our modern devices – just in a more creative way. Rather than being used as a fossil fuel to produce electricity, coal can be transformed via a new processing technique into extremely high-purity materials that can be used to build electronic components.

The researchers say that their new research is an effective proof-of-principle and could have significant implications for the semiconductor industry.

The next frontier: 2D electronics

Against a backdrop of demand for increasingly faster, smaller, more powerful electronics, the natural conclusion of such a push is the development of electronic parts from ultra-small materials – possibly just one or two atoms thick. This concept of “two-dimensional electronics” is the limit for electronics miniaturization and promises incredibly small devices that consume tiny amounts of energy but

New Bill Seeks To Remove Power To Suspend Electronic Media During Emergency

(BIVN) – A new bill that would “remove the ability of the governor or a mayor to suspend electronic media transmission during a state of emergency” is making its way through the Hawaiʻi State Legislature.

House Bill 2581 (HD 1) has already passed through the State House and will be heard in the Senate Committee on Public Safety and Intergovernmental and Military Affairs on Monday, March 11.

From the language of the bill:

The legislature finds that the power of the governor or a mayor to suspend the transmission of electronic media during a state of emergency is overly broad and vague. Electronic media could include not only all radio and television broadcasts, but could also potentially include text, emails, and posts to social media platforms, which would restrict legally free speech and publication and violate the First Amendment of the United States Constitution.

The proposed bill may sound familiar. Last year, House Bill 522 made its way through the State Legislature.

In this year’s House Judiciary & Hawaiian Affairs Committee hearing on the new bill, Chris Leonard of New West Broadcasting Corp and president of the Hawaiʻi Association of Broadcasters, said that last year’s bill made it to conference

DISTURBED Scores First Hit On Billboard’s Hot Dance/Electronic Songs Chart With “The Sound Of Silence” Remix

DISTURBED Score First Hit On Billboard's Hot Dance/Electronic Songs Chart With "The Sound Of Silence" Remix

Disturbed are enjoying some very surprising success on one particular Billboard chart – one that both the members of the outfit and their followers likely never expected them to appear on, reports Forbes.

The hard rockers score an unlikely hit on this week’s Hot Dance/Electronic Songs chart. Disturbed appears on Billboard’s ranking of the most-consumed dance and electronic tunes in the US for the first time in their many years together.

A remix of Disturbed’s song, “The Sound Of Silence” arrives at #34 on this week’s Hot Dance/Electronic Songs chart. The tune was recently reworked by producer Cyril, and it’s that version, which is very different from the original, that helps bring the band to the tally.

Disturbed’s “The Sound Of Silence” is new to the Hot Dance/Electronic Songs chart, but it’s already appeared on another ranking in the same genre published by Billboard. A month ago, the tune reached the Dance/Electronic Digital Song Sales chart, which tracks the bestselling cuts in either of those styles–or usually both–in the United States.

Electronic pathways may enhance collective atomic vibrations’ magnetism | Rice News | News and Media Relations

Materials with enhanced thermal conductivity are critical for the development of advanced devices to support applications in communications, clean energy and aerospace. But in order to engineer materials with this property, scientists need to understand how phonons, or quantum units of the vibration of atoms, behave in a particular substance.

“Phonons are quite important for studying new materials because they govern several material properties such as thermal conductivity and carrier properties,” said Fuyang Tay, a graduate student in applied physics working with the Rice Advanced Magnet with Broadband Optics (RAMBO), a tabletop spectrometer in Junichiro Kono’s laboratory at Rice University. “For example, it is widely accepted that superconductivity arises from electron–phonon interactions.

“Recently, there has been growing interest in the magnetic moment carried by phonon modes that show circular motion, also known as chiral phonons. But the mechanisms that can lead to a large phonon magnetic moment are not well understood.”

Now an international team of researchers led by Felix Hernandez from Brazil’s Universidade de São Paulo and Rice assistant research professor Andrey Baydin has published a study detailing the intricate connections
