Van der Waals opto-spintronics - Nature Electronics
Abstract Van der Waals materials with long-range magnetic order show a range of correlated phenomena that could be of use in the development of optoelectronic and spintronic applications. Magnetically ordered van der Waals semiconductors with spin-polarized currents are, in particular, sensitive to external stimuli such as strain, electrostatic fields, magnetic fields and electromagnetic radiation.
Exploiting two-dimensional morphology of molybdenum oxycarbide to enable efficient catalytic dry reforming of methane
Abstract The two-dimensional morphology of molybdenum oxycarbide (2D-Mo2COx) nanosheets dispersed on silica is found vital for imparting high stability and catalytic activity in the dry reforming of methane. Here we report that owing to the maximized metal utilization, the specific activity of 2D-Mo2COx/SiO2 exceeds that of other Mo2C catalysts by ca. 3 orders of magnitude.

Death by disdain: the fate of drug users in Russian-occupied territories
With replacement therapy now illegal, drug users in Russian-occupied Crimea and the self-proclaimed republics of the Donbas are finding it hard to survive. RU In 2014, Donetsk native Yevgeny Selin had his own business, a car and an apartment he bought with his own money. Besides work, Selin was involved in civil society, fighting for the rights of addicts, and was in contact with representatives of Ukraine’s Ministry of Health.
The Key RuV=O Intermediate of Site-Isolated Mononuclear Water Oxidation Catalyst Detected by in Situ X-ray Absorption Spectroscopy
Improvement of the oxygen evolution reaction (OER) is a challenging step toward the development of sustainable energy technologies. Enhancing the OER rate and efficiency relies on understanding the water oxidation mechanism, which entails the characterization of the reaction intermediates.
Russia’s new media law: expanding the field of uncertainty
The Russian state currently lives for two problems — its relations with the US, and the upcoming presidential elections. Society is worried about something slightly different — the state of the healthcare system, rising taxes and reducing incomes. But it’s the authorities who set the priorities in Russia, and they don’t often consult citizens.
Russia’s new foreign agent legislation will further silence independent media
On 22 November, Russia’s Federation Council approved new legislation designed to assign “foreign agent” status to foreign media organisations. Previously voted through by the Russian parliament, this new “foreign agents” law was received 154 votes, with one abstention. There’s no doubt that Vladimir Putin will soon sign the document into law. The question now is: how will this legislation, which was clearly written in a rush, be applied?
A hyperlink to absurdity
“We actually thought we had ‘mopped up’ our website and got rid of those ‘undesirable’ hyperlinks, but we missed one,” Anya Sarang told me, chuckling ruefully. Sarang is the head of the Andrei Rylkov Foundation, a prominent Russian group working to advance responsible drug policy. This week, a court in Moscow fined the group 50,000 rubles (US$862) for involvement with an “undesirable organisation”.
Digital sovereignty à la russe
December 2016 saw Russia adopt a new Information Security Doctrine. Signed off by President Putin, the 2016 document replaced the outdated ISD from 2000.
Artpodgotovka: six days to destroy a movement
This week has seen members of a Russian radical nationalist movement searched, detained and charged with various offences, including terrorism. We continue our partnership with OVD-Info, an NGO that monitors politically-motivated arrests in Russia. Every Friday, we bring you the latest information on freedom of assembly.
Chelyabinsk copper plant conflict reaches new (and sad) lows
A copper mining complex in one of Russia’s most polluted regions has been given the go-ahead — and is fraught with intimidation at the local level. RU Despite the open protests by ecologists and locals, it seems the Tomino copper mining complex is going ahead. This month, Russia’s largest extractor of copper ore received permission to build in the Chelyabinsk region, in the southern Urals.
“It was like hell in miniature”: how Rostov-on-Don lost a whole neighbourhood in one day
On 21 August, the southern Russian city of Rostov suffered the worst fire in its history. In the space of a few hours an entire district in the city centre, which is known locally as Govnyarka, burned to the ground. The fire broke out at about 1pm and spread at incredible speed. Ten buildings, mostly of one and two storeys, were destroyed in the first hour, and 25 in the following three hours. More than 600 people were evacuated.
Stop GOK: how residents of Chelyabinsk are resisting plans for a new copper plant
Twelve kilometres from the city of Chelyabinsk, the Russian Copper Company (RMK) is planning to build a new ore mining and enrichment plant. This Urals city, where local residents claim there’s already nothing to breathe, is protesting how it can. But so far, they haven’t been successful in stopping RMK’s advances.
No home, no work, no family: the difficulties of rehabilitation for Russia’s ex-prisoners
Russia has one of the highest recidivism rates in the world. According to the Federal Penitential Service, more than half of Russia’s prison population at any moment consists of people who have done time before. Committing a second offence and going back inside can be the result of a number of factors. Among them are the nature of the prison system itself, the lack of any effective rehabilitation programmes, financial difficulties after release and the stigmatisation of ex-offenders.
My first death threat: the life and times of a Russian ecological activist
On 12 April, Yaroslav Nikitenko woke up to a frightening sight by the entrance of his apartment: graffiti reading “Shut the hell up or…”, the phrase accompanied by a drawing of a gravestone bearing Nikitenko's name. It was encircled by black crosses. Nikitenko, a 29-year old physicist working at the Institute for Nuclear Research at the Russian Academy of Sciences, had spent the last months campaigning against the building of a luxury residential complex at 21 Zhivopisnaya street.
Russian authorities ramp up repression against anti-corruption protesters
We continue our partnership with OVD-Info, an NGO that monitors politically-motivated arrests in Russia. Every Friday, we bring you the latest information on freedom of assembly in Russia. This week, Russia’s Investigative Committee finished its initial investigation into three of the four men charged in the “26 March” case — Yuri Kuliy, actor, Aleksandr Shpakov, joiner, and Stanislav Zimovets, political activist.
Our city, our space: Ekaterinburg residents come out against plans to construct a new church
In Ekaterinburg, city residents are speaking out against proposals to construct a new church in the centre of the city — proposals entirely out of sync with their interests. ??????? One and a half thousand people, all arm in arm, line the edge of Ekaterinburg’s city pond. At a recent flashmob called “Embrace the pond”, city residents came out against plans to build a new church dedicated to St Ekaterina directly in the pond’s waters.
Kicking habits, kicking back
In Russia, a punitive Soviet approach to drug users is still in place. But a new generation of activists is ready to challenge it. When Russian media report an increase or decrease in drug addiction in the country, they are usually only reflecting the number of users officially registered at state clinics. The practice of putting anyone requesting treatment for drug abuse on the drug users register traces its roots back to the Soviet era, but it has made a smooth transition.
