first_imgFacebook0TwitterEmailPrintFriendly分享The hours at the Sterling transfer site change to 10am to 6pm, starting on Sunday. Beginning October 1 the transfer site is closed on Sundays through the winter. Questions? Call the Kenai Peninsula Borough Solid Waste Department (907) 262-9667. From October to May each year the landfill will be open 10am to 6pm, Monday-Saturday. The Kenai Peninsula Borough Assembly voted back in 2016 to close Borough dumps on Sunday from October to May. October 1 will kick off the seasonal landfill closure. The Central Peninsula Landfill and Kasilof, Kenai, Nikiski and Sterling Transfer Sites will be closed on Sundays for the winter beginning October 1 through April 28, 2019. Sundays will re-open for the summer season.last_img

South Sudan Accuses US of Blocking Path to Countrys Peace

first_imgBy The Associated PressSouth Sudan’s government on May 9 lashed out at the United States after the Trump administration threatened to cut off hundreds of millions of dollars in humanitarian aid amid the country’s grinding civil war, calling the U.S. “a real obstacle” toward achieving peace.The statement from President Salva Kiir’s office also accused the Trump administration of “naked direct interference” in South Sudan’s affairs ahead of peace talks that resume May 17 in neighboring Ethiopia, mediated by a regional bloc.Five years into South Sudan’s civil war more than seven million people are facing severe hunger without food aid, according to the latest analysis by the U.N. and the government. (AP Photo/Sam Mednick)The U.S. is the top aid donor to South Sudan, but in a sharply worded statement on Tuesday it said it would review its assistance if the East African nation’s conflict grinds on. The U.S. says it has given over $3.2 billion in humanitarian assistance since the conflict broke out in December 2013.The absence of aid would have a devastating impact on more than seven million South Sudanese facing severe hunger as aid workers say famine could return.International frustration has been rising with South Sudan’s warring sides, especially after a cease-fire late last year was violated within hours. Tens of thousands of people have been killed and more than 2 million people have fled the country, creating Africa’s largest refugee crisis since the Rwandan genocide in 1994.While the South Sudan statement accused the armed opposition of blocking the path to peace by putting forward what it called impractical proposals, it noted that Kiir has invited former deputy and opposition leader Riek Machar to return to the country and given him 45 days to do so in an attempt to “reconcile with opposition leaders.” Machar fled during renewed fighting in 2016.“Without a genuine peace Machar is not coming,” a spokesman for Machar’s group, Lam Paul Gabriel, told The Associated Press.A new collection of opposition parties, which doesn’t include Machar’s supporters, on Wednesday commended the U.S. statement and accused South Sudan’s government of “tirelessly working to undermine the prospect” of peace.One South Sudan conflict expert urged both sides to stop the attacks.“The United States’ statement was a bit harsh but there’s no way the government of South Sudan should fight with them,” Jacob Chol, professor of comparative politics at the University of Juba, told the AP. “What should happen is more engagement instead of antagonistic fighting back. It’s not good for the welfare of the South Sudanese.”last_img read more

Safer way to make diazomethane developed

first_img Diazomethane (CH2N2) is a toxic yellow gas at 25 degrees Celsius, and is usually used in solution in ether. It is a useful reagent for many reasons, such as its ability to be converted to carbene, which is used in the synthesis of cyclopropanes. It is usually prepared as needed in the lab by hydrolysis of a precursor such as diazald (N-methyl-N-nitroso-p-toluenesufonamide), but becomes explosive during the processes of purifying and isolating it. Safety precautions such as preparing the chemical in a fume hood or behind a blast shield, avoiding ground glass joints, wearing thick protective gloves, avoiding any sharp edges or scratches on the glassware, and so on, are employed during the synthesis to protect the scientists from potential explosions.Researchers Erick Carreira and Bill Morandi of the Laboratory of Organic Chemistry at ETH in Zurich have developed a new method for generating diazomethane in situ that uses a catalyst and avoids the need for the dangerous isolation process and generation of large volumes of the explosive chemical. The catalyst is an iron porphyrin complex and is used to catalyze the cyclopropanation of olefins such as styrenes, dienes, and enynes in an aqueous solution of potassium hydroxide (6M, KOH). Since olefins are immiscible with water, they create a safe biphasic environment for the formation of the intermediate, diazomethane, which is constantly generated and immediately consumed in the reaction. The catalyst remains within the olefin phase.The new method is safer for the chemists because there is a much lower risk of explosion since the diazomethane is consumed as soon as it is created, and large volumes do not accumulate. There is also a much lower chance of exposure to the toxic gas.In the paper, published in Science, Carreira and Morandi suggest the method could also be used in the synthesis of other toxic or explosive reagents, provided they can be prepared in aqueous solutions. More information: Iron-Catalyzed Cyclopropanation in 6 M KOH with in Situ Generation of Diazomethane, Science 23 March 2012: Vol. 335 no. 6075 pp. 1471-1474, DOI: 10.1126/science.1218781ABSTRACTDiazomethane is a common and versatile reagent in organic synthesis whose broader use is generally impeded by its explosiveness and toxicity. Here we report that a simple iron porphyrin complex catalyzes the cyclopropanation of styrenes, enynes, and dienes under the demanding conditions [aqueous 6 molar potassium hydroxide (KOH) solution, open to air] necessary for the in situ generation of diazomethane from a water-soluble diazald derivative. A biphasic reaction medium arising from the immiscibility of the olefin substrates with water appears essential to the overall efficiency of the process. The work we describe highlights an approach to catalysis with untoward reactive intermediates, in which the conditions for their generation under operationally safe regimes dictate catalyst selection.

(PhysOrg.com) — Diazomethane is a toxic, explosive reagent prepared as needed in laboratories, where it is commonly used in cyclopropanation, but its explosive nature prevents it being used widely on an industrial scale. Now, scientists in Switzerland have developed a new method of synthesising diazomethane that is much safer and therefore could lead to much wider use.
