Why five decades of massive research on heterogeneous photocatalysis, especially on TiO2, has not yet driven to water disinfection and detoxification applications? Critical review of drawbacks and challenges

César Pulgarin, Julian Andrés Rengifo Herrera

For fifty years, heterogeneous photocatalysis has been considered as having potential to remove organic and microbiological pollutants from water under either artificial UV light or sunlight irradiation. However, after tens of thousands of published resear ...

Clathrate structure-type recognition: Application to hydrate nucleation and crystallisation

Simone Meloni

For clathrate-hydrate polymorphic structure-type (sI versus sII), geometric recognition criteria have been developed and validated. These are applied to the study of the rich interplay and development of both sI and sII motifs in a variety of hydrate-nucle ...

Capillarity in pressure infiltration: influence of percolation and wetting angle

Andreas Mortensen, William Craig Carter, Ludger Weber, Alain Léger, Gionata Schneider

Composite materials are often produced by pressure-infiltration of a liquid matrix into a preform of packed solid fibers or particles. Capillary forces that intervene in this process are quantified by measuring saturation curves, which are plots of the fra ...

On The Strategies Towards Isothermal Gas Compression And Expansion

Alfred Rufer, Mahbod Heidari, Sylvain Lemofouet-Gatsi

Isothermal compression/expansion is regarded as the most promising process in many applications and many researchers and inventors have tried different methods to achieve this goal. The current article first studies the gradual roadmap from adiabatic towar ...

Principle of Hybrid Energy Storage Systems based on Hydro-pneumatics and Supercapacitors for Distributed Generation and Renewable Energy Sources Support

Alfred Rufer

This paper presents hybrid energy storage systems based on hydro-pneumatics and Supercapacitors with high potentials regarding life cycle and impacts on environment. These so called “Batteries with Oil-hydraulics and Pneumatics (BOP)” systems exploit the h ...

Self-assembly and dynamics of poly(γ-benzyl-L-glutamate) peptides

Harm-Anton Klok

The structure and the associated dynamics have been investigated in a series of oligopeptides of γ-benzyl-L-glutamate using DSC, WAXS, FTIR, NMR and dielectric spectroscopy, and rheology, respectively. The peptides with degrees of polymerization below 18 a ...

Premelting Effects In Minerals - An Experimental-Study

Philippe Gillet

High-temperature calorimetry experiments show that the isobaric heat capacity (C(p)) of minerals increases in an anomalously rapid way when the melting point is approached. These premelting effects can begin a few hundred degrees below the melting point, a ...

Anharmonicity And High-Temperature Heat-Capacity Of Crystals - The Examples Of Ca2GeO4, Mg2GeO4 And CaMgGeO4 Olivines

Philippe Gillet

Drop-calorimetry determinations of the isobaric heat capacity (C(P)) of Mg2GeO4, Ca2GeO4 and CaMgGeO4 have been made up to 1700 K. The thermal expansion coefficient (alpha) of these olivine germanates has been determined from high-temperature X-ray measure ...

High-Temperature Thermodynamic Properties Of Forsterite

Philippe Gillet

The high-temperature thermodynamic properties of forsterite were reviewed in the light of a new determination of the isobaric heat capacity (C(p)), up to 1850 K, and Raman spectroscopic measurements, up to 1150 K and 10 GPa. The C(p) measurements and avail ...
