Influence of calcium to silica ratio on aluminium uptake in calcium silicate hydrate

Karen Scrivener, Barbara Lothenbach, Émilie Michèle L'Hôpital

Aluminium uptake in calcium silicate hydrate (C-S-H) was studied at different Ca/Si ratios from 0.6 to 1.6 at 20 degrees C. Aluminium incorporation in C-S-H depends on the total amount of aluminium present in the sample. At low Al/Si ratio (

Harmonium: A pulse preserving source of monochromatic extreme ultraviolet (30–110 eV) radiation for ultrafast photoelectron spectroscopy of liquids

Majed Chergui, Hua Zhang, Frank van Mourik, Christopher Alexander Arrell, Lars-Hendrik Mewes, José Javier Pancracio Ojeda Andara, Jakob Grilj

A tuneable repetition rate extreme ultraviolet source (Harmonium) for time resolved photoelectron spectroscopy of liquids is presented. High harmonic generation produces 30-110 eV photons, with fluxes ranging from similar to 2 x 10(11) photons/s at 36 eV t ...

Spectroscopic studies of kinetically trapped conformations in the gas phase: the case of triply protonated bradykinin

Thomas Rizzo, Liudmila Voronina

Understanding the relation between the gas-phase structure of biological molecules and their solution-phase structure is important when attempting to use gas-phase techniques to address biologically relevant questions. Directly after electrospray ionizatio ...

Quantification of Conventional and Nonconventional Charge-Assisted Hydrogen Bonds in the Condensed and Gas Phases

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Sviatlana Siankevich

Charge-assisted hydrogen bonds (CAHBs) play critical roles in many systems from biology through to materials. In none of these areas has the role and function of CAHBs been explored satisfactorily because of the lack of data on the energy of CAHBs in the c ...

Direct observation of nanoscale interface phase in the superconducting chalcogenide KxFe2-ySe2 with intrinsic phase separation

Davide Innocenti

We have used scanning micro x-ray diffraction to characterize different phases in superconducting KxFe2-ySe2 as a function of temperature, unveiling the thermal evolution across the superconducting transition temperature (T-c similar to 32 K), phase separa ...

Hydration states of AFm cement phases

Karen Scrivener, Thomas Matschei, Mahsa Saeidpour

The AFm phase, one of the main products formed during the hydration of Portland and calcium aluminate cement based systems, belongs to the layered double hydrate (LDH) family having positively charged layers and water plus charge-balancing anions in the in ...

Criticality in the Approach to Failure in Amorphous Solids

Matthieu Wyart, Jie Lin

Failure of amorphous solids is fundamental to various phenomena, including landslides and earthquakes. Recent experiments indicate that highly plastic regions form elongated structures that are especially apparent near the maximal shear stress Sigma(max) w ...

Direct access to macroporous chromium nitride and chromium titanium nitride with inverse opal structure

Weitian Zhao

We report a facile synthesis of single-phase, nanocrystalline macroporous chromium nitride and chromium titanium nitride with an inverse opal morphology. The material is characterized using XRD, SEM, HR-TEM/STEM, TGA and XPS. Interconversion of macroporous ...

Predicting the state and properties of Deepwater Horizon oil under pressure using the Peng-Robinson equation of state

Jeremy Samuel Arey, Jonas Gros

Being able to estimate the partitioning behavior of the live oil mixture between a gas and a hydrocarbon liquid phase is crucial for valid modeling of the behavior of the emitted fluid. Equations of state are a well-known way to estimate the phase partitio ...
