“Mechanically strong yet metabolizable supramolecular plastics by desalting upon phase separation” #PDF #paper #materials “A strong, glassy supramolecular polymer has been shown to prevent the formation of marine microplastics by slowly dissolving in salt water into metabolizable compounds. Cheng et al. show that salt bridging between sodium hexametaphosphate or sulfated polysaccharides and guanidinium sulfates expels sodium sulfate to create a cross-linked network that is stable until the electrolytes are added back. The dried material is a moldable and recyclable thermoplastic that can be water stabilized with hydrophobic coatings.”

the #Deep-State term was popularized in this “letter” in the New Yorker on March 12, 02012, by Dexter Filkins, entitled “THE DEEP STATE: The Prime Minister [Erdogan] is revered as a moderate, but how far will he go to stay in power?” #Turkey #politics #history
The New Yorker’s #Deep-State “letter” from 02012, now without the subtitle describing Erdogan as a “moderate”; apparently the phrase “deep state” is a translation of the Turkish derin devlet. #Turkey #politics #history
the Turkish article on the #Deep-State concept semes to say “derin devlet” is an abbreviation of “devlet içinde devlet”, “imperium in imperio”, an empire within an empire. But “devlet” is translated as “state”, and “derin” means “deep”.
> “Deep state” is a calque of the Turkish word derin devlet (lit. ‘deep state’). The modern concept of a #deep-state is associated with #Turkey, a presumed secret network of military officers and their civilian allies trying to preserve the secular order based on the ideas of Mustafa Kemal Atatürk from 1923. #politics
An article from 02014 about the #deep-state concept by Mike Lofgren, criticizing the military-industrial-intelligence complex. He explains the term: “The term “Deep State” was coined in Turkey and is said to be a system composed of high-level elements within the intelligence services, military, security, judiciary and organized crime. In British author John le Carré’s latest novel, A Delicate Truth, a character describes the Deep State as “… the ever-expanding circle of non-governmental insiders from banking, industry and commerce who were cleared for highly classified information denied to large swathes of Whitehall and Westminster.” I use the term to mean a hybrid association of elements of government and parts of top-level finance and industry that is effectively able to govern the United States without reference to the consent of the governed as expressed through the formal political process.” #politics #USA

more on the #China #Wandering-Balloon: “Regarding the unintended entry of a Chinese unmanned airship into US airspace due to force majeure, the Chinese side has verified it and communicated it to the US side. It is a civilian airship used for research, mainly meteorological, purposes. Affected by the Westerlies and with limited self-steering capability, the airship deviated far from its planned course.” #USA #UFOs #politics #history
BBC reporting at the time on the #China #USA #Wandering-Balloon #politics, apparently the most comprehensive coverage
#China #USA #Wandering-Balloon #politics reporting: “The balloon, which spent five days traveling in a diagonal southeast route from Idaho to the Carolinas, had moved off the coast by midday Saturday and was shot down within moments of its arrival over the Atlantic Ocean. (...) Pentagon officials advised then against shooting down the balloon, whose belly structure was roughly the size of three buses. (...) Pentagon officials said the spy balloon, which was remotely maneuverable to some degree by the Chinese but still dependent on the jet stream for travel, began its controlled drift into American territory on Jan. 28, when it entered Alaskan airspace near the Aleutian Islands. (...) the most recent balloon, equipped with solar panels to power propulsion and cameras and surveillance technology, exited American territory on Monday and spent the day over Canada’s Northwest Territories. But it was back over the United States on Tuesday after entering through northern Idaho.”

Russian propaganda channel WION clarifies that the #Oreshnik was “2.5-3 kilometers per second” which would be mach 7.5-9 at sea level. Dmitry Babich (foreign editor, kp.ru news) blames the war on the West’s “gender ideology, woke ideology” #Ukraine #news #video

#TRT #news says Erdogan calls for “restraint”, seeming “very, very concerned” and saying NATO “needs to prepare”, and “opposes #Ukraine’s use of US long-range missiles”, which #Turkey calls a “mistake”. Also an interview with Sergey #Karaganov, advisor to Putin. He also says that under [circumstances I didn’t understand] the #USA and Western Europe would “get a nuclear response”. Former Turkish diplomat Gulru Gezer says she’s getting “chills on my spine” from the US and Russian rhetoric from the other panelists. Karaganov: “The problem is two-pronged. One is to win the victory in Ukraine over the West, not over Ukraine. [The] West has to be defeated. Second, the third world war could be avoided.” He accidentally called Putin “president Yeltsin” at one point. #video #politics
#Karaganov “has been Presidential Advisor to both Boris Yeltsin and Vladimir Putin. He is considered close to Putin and Sergey Lavrov. (...) has been a member of the Trilateral Commission since 1998, and served on the International Advisory Board of the Council on Foreign Relations. He has also been Deputy Director of the Institute of Europe at the USSR (now Russian) Academy of Sciences since 1983.” I guess that means he’s been a major architect of Russian foreign policy since literally Andropov. #politics #Russia #Ukraine
