The rating agency Fitch on Wednesday put the country's "AAA" credit rating on a negative watch ahead of possible inaction by Congress to raise the debt ceiling. She said the government's balance would be inadequate to satisfy an estimated $92 billion of payments and transfers, including a scheduled investment in the Social Security and Medicare trust funds of about $36 billion.Īs a result of the debt-ceiling standoff, Yellen said the Treasury has already seen borrowing costs increase substantially for securities maturing in early June. Yellen said the Treasury is set to make more than $130 billion of scheduled payments in the first two days of June including payments to veterans and Social Security and Medicare recipients, leaving the department with "an extremely low level of resources." "It's very close and I'm optimistic," Biden said. But they still have disagreements on expanded work requirements for welfare programs and expedited permitting for oil and gas projects.īiden, before departing the White House Friday evening for the Camp David presidential retreat, told reporters "things are looking good" and he hopes to have "some clear evidence tonight before the clock strikes 12" that a deal is finalized. The two sides are nearing a new deal to raise the debt ceiling through 2024 and fulfill Republican demands for spending cuts. The more precise projection, outlined in a letter to House Speaker Kevin McCarthy, gives President Joe Biden and McCarthy additional time to strike a deal to raise the debt ceiling and avert a default as they head into Memorial Day weekend. is on track to default in early June and "as early as June 1," which had White House and Republican negotiators targeting the first of the month for a deal. Treasury Secretary Janet Yellen Friday provided an updated timeline for when the government could run out of money, saying her projection is now by June 5 based on the most recent data if Congress does not raise or suspend the debt ceiling. has an extra four days to avoid defaulting on its debt. Second order nonlinear optical (NLO) measurements were performed by Harmonic Light Scattering and the contribution of the DASP(+) moieties (and their relative ordering) and the metal-polypyridyl core need to be considered to explain the nonlinear optical properties of the metal complexes.WASHINGTON − The U.S. A quenching of luminescence was evidenced in all ruthenium complexes compared with the free pro-ligands but even the terpyridine-functionalized metal complexes exhibited detectable luminescence at room temperature. A fairly good agreement was observed between the experimental and the calculated electronic spectra of the pro-ligands and their corresponding ruthenium complexes. The structural, electronic, and optical properties of the pro-ligands and the ruthenium complexes were investigated using density functional theory (DFT) and time-dependent (TD) DFT calculations. The corresponding multifunctional Ru(II) and Zn(II) complexes were prepared and investigated. The synthesis, linear optical and nonlinear optical properties, as well as the electrochemical behavior of a series of pro-ligands containing the 4-(4-N,N-dimethylaminostyryl)-1-methyl pyridinium (DASP(+)) group as a push-pull moiety covalently linked to terpyridine or bipyridine as chelating ligands are reported in this full paper.
