Ocean acidification (OA) is predicted to reduce reef coral calcification rates and threaten the long-term growth of coral reefs under climate change. Reduced coral growth at elevated pCO2 may be buffered by sufficiently high irradiances; however, the

The Kondo properties of the impurity Anderson model provide a theoretical framework for relating thermodynamic and angle integrated electron spectroscopy data in many heavy fermion materials. We describe the success and the challenges of this approac

Resonant x-ray magnetic scattering is used to study magnetic order near the (001) surface of the antiferromagnetic oxide UO{sub 2} for temperatures between 10 and 35 K. It is found that for temperatures below the bulk Neel temperature a magnetically

Measurements of 500 eV 4 He + scattered from Al(111) surfaces provide detailed information about the scattering process and surface crystallography. We report various observations concerning collision inelasticity, multiple scattering, and shadow-con

We present temperature-dependent photoemission (PES) measurements on single-crystalline YbInCu{sub 4}, a stoichiometric material that shows an isostructural first-order valence transition at T{sub a}{approx}60 K. The results of the analysis of the PE

We have taken angle-resolved data for the scattering of low-energy (4 He + from deuterium adsorbed on a stepped Pd (331) surface. The impact geometry was "up the staircase," i.e. the 4 He + beam was perpendicular to and directly incident onto the uns

The Fermi surfaces and single-particle spectral functions of several low-dimensional materials have been measured as part of an effort to assess the occurrence of non-Fermi-liquid behaviour in non-cuprate materials.

We report glancing-incidence x-ray scattering studies of the magnetic structure observed near the (001) surface of the antiferromagnet UO{sub 2}. Within about 50A of the surface, the magnetic scattering intensity decreases continuously as the bulk N{

The electronic structure of the layered compound 1T-${\mathrm{TiTe}}_{2}$ has been studied in detail by high-resolution angle-resolved photoelectron spectroscopy (ARPES) and density-functional band calculations. The results confirm the semimetallic n

We present angular resolved photoemission data of the quasi-one-dimensional metals K 0.3 MoO 3 and (TaSe 4 ) 2 I. The measured conduction band dispersions reflect the highly anisotropic nature of these materials. However, no clear Fermi-Dirac cutoff
