Effect of soil structuring on stiffness evaluated by triaxial and seismic flat dilatometer tests [PDF]

open access: yesE3S Web of Conferences
Granitic residual soils are considered structured soils. The bonding between the particles and the fabric inherited by the original rock play an important role in controlling the mechanical behaviour.

Indicators of hot fluid migration in sedimentary basins: evidence from the UK Atlantic Margin [PDF]

open access: yes, 2003
Microthermometric, petrographic and isotopic methods have been used to detect evidence for hot fluid flow in Mesozoic and Tertiary sediments from the NW UK continental margin, West of Shetland. New data presented here show that temperatures are hotter by

The Impact of DNA as a Chemical Admixture for Cementitious Materials

open access: yesAdvanced Materials Technologies, EarlyView.
DNA molecules are added to cement pastes and their effects on rheology and hydration time are studied. DNA's chemical structure is composed of polysaccharide and phosphate groups, which are active functional groups in different commercial chemical admixtures: Viscosity modifiers and superplasticizers.

Survey of the diagenesis process and effect these process on reservoir quality of the Kangan formation in South Pars Field [PDF]

open access: yes, 2009
Kangan and Upper Dalan formations are forming reservoir sequence of the South Pars field. Litology of the kangan formation is carbonate and (limestone and dolomite with anhydrite intervals), so digenetic processes were very active in this formation and ...

Microstructure and chemical composition of Roman orichalcum coins emitted after the monetary reform of Augustus (23 B.C.) [PDF]

open access: yes, 2019
A collection of ancient Roman orichalcum coins, i.e., a copper-zinc alloy, minted under the reigns from Caesar to Domitianus, have been characterised using scanning electron microscopy (SEM-EDS) and electron microprobe analysis (EMPA).

Development of a Miniaturized Capillary Rheometer for High Shear Rate Rheology of Dense Suspensions

open access: yesAdvanced Materials Technologies, EarlyView.
This research presents a downscaled benchtop, low‐cost capillary rheometer that can characterize high shear rate rheometry of dense suspensions. The device is capable of measuring across a wide range of applicable shear rates using only a limited quantity of material and addresses a need for an accurate and affordable capillary rheometer.

Hyperphosphorescent OLEDs: Harnessing the Power of MR‐TADF Terminal Emitters

open access: yesAdvanced Optical Materials, EarlyView.
Hyperphosphorescent organic light‐emitting diodes (HP‐OLEDs) use phosphorescent sensitizers with multiresonant thermally activated delayed fluorescence terminal emitters. HP‐OLEDs show efficient, narrowband electroluminescence and moderate efficiency roll‐off.
