Judge temporarily blocks DOE’s move to slash university research funding
A group of universities led by the American Association of Universities (AAU) acted swiftly to oppose a policy action by the Department of Energy that would cut the funds it pays to universities for the indirect costs of research under DOE grants. The group filed suit Monday, April 14, challenging a what it termed a “flagrantly unlawful action” that could “devastate scientific research at America’s universities.”
By Wednesday, the U.S. District Court judge hearing the case issued a temporary restraining order effective nationwide, preventing the DOE from implementing the policy or terminating any existing grants.

We investigated tritium (T) release behavior from silica glass. The specimens were 8 kinds of commercially available silica glass. T was injected by the 6Li (n,α)T reaction of sintered pellets of lithium oxide (Li2O) into the silica glass with thermal neutrons in JRR-2 (VT-8) up to 5 × 1018 neutrons/cm2 at ambient temperature (about 350 K). After irradiation, the Li2O pellets were removed from the silica glass, and T release from the silica glass was measured in a flow of hydrogen (H2) or ammonia (NH3) sweep gas at atmospheric pressure at a constant heating rate of 2 K/min between 675 K and 1375 K with a proportional counter. In the case of H2 sweep gas, a maximum tritium release rate was observed around 1023 K, while in the case of NH3 sweep gas, two peaks around 1023 K and around 1123 K or a peak around 1123 K with a shoulder were obserbed. After the experiments of T release, FT-IR spectra showed a decrease of SiOH bands at 3650 cm−1. On the other hand, no changes in intensities at 2250 cm−1 due to SiH were observed for both samples before and after T release.
