[1] Numerous hot springs flow within the steeply incised gorges of the central Nepal Himalayan front. The spring fluids have total dissolved solids (TDS) up to 7000 mg/L and Na, and K typically comprise >50% of the cationic charge, indicating that high-temperature silicate alteration is the dominant source of hot spring alkalinity. HCO3 is normally the dominant anion. Sr isotope ratios from the...

As a promising electronic material, Ge nanowire (GeNW) has attracted much attention for its low band gaps, high mobilities, and unprecedented dimensions. This article reviews recent research and advancement on this topic and summarizes many aspects of GeNWs, including preparation, surface chemistry, physical properties, functional devices, and controlled assembly. It is shown that GeNWs can be ...

In describing the testing of the AN/ALQ-131 jammer, under the heading “Band 3 Ineffective Against Some Threats”, GAO Report /NSIAD-1995-47, said: “Developmental testing conducted after the Band 3 entered production has shown that the system has serious performance problems. New, but preliminary, test results compiled after the draft of this report was prepared indicate some improvement in perfo...

MDL 62,879 (GE2270 A) is a new peptide antibiotic that inhibits protein synthesis through an interaction with elongation factor Tu. MDL 62,879 was very active against gram-positive clinical isolates, particularly staphylococci and enterococci, for which MICs for 90% of isolates were < or = 0.13 micrograms/ml. It was equally active against isolates resistant to beta-lactams, erythromycin, gentam...

The authors use double quantum dot transport measurements to reveal the presence of a strong spin-orbit interaction in Ge/Si nanowires. They also show that this gives rise g-factor renormalization with magnetic field.

The title compound, C(56)H(56)Ge(4)O(2)·2CH(2)Cl(2) or Tol(8)Ge(4)O(2)·2CH(2)Cl(2) (Tol = p-CH(3)C(6)H(4)), was obtained serendipitously during the attempted synthesis of a branched oligogermane from Tol(3)GeNMe(2) and PhGeH(3). The mol-ecule contains an inversion center in the middle of the Ge(4)O(2) ring which is in a chair conformation. The Ge-Ge bond distance is 2.4418 (5) Å and the Ge-O bo...
