The Influence of Seafloor Gradient on Turbidity Current Flow Dynamics and Depositional Response: A Case Study from the Lower Gas-Bearing Interval of Huangliu Formation II, Yinggehai Basin

open access: yesJournal of Marine Science and Engineering
The Huangliu Formation, Section I, Gas Group II, at the eastern X gas field of the Yinggehai Basin, hosts thick, irregularly deposited sandstone bodies. The genesis of these sedimentary sand bodies has remained unclear.

SOC in a population model with global control

open access: yes, 1999
We study a plant population model introduced recently by J. Wallinga [OIKOS {\bf 74}, 377 (1995)]. It is similar to the contact process (`simple epidemic', `directed percolation'), but instead of using an infection or recovery rate as control parameter ...

Crystal nucleation and cluster-growth kinetics in a model glass under shear [PDF]

open access: yes, 2010
Crystal nucleation and growth processes induced by an externally applied shear strain in a model metallic glass are studied by means of nonequilibrium molecular dynamics simulations, in a range of temperatures.

Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

Experimental bedforms by saline density currents

open access: yesBrazilian Journal of Geology, 2019
Bedforms are sedimentary features that can be generated on the seafloor by the interaction between density currents and mobile beds. Developing knowledge about the hydraulic and sedimentary processes involved during these events is in the interest of ...

Emerging research directions in nanoparticle‐based foam control for bioprocessing: a bibliometric approach

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Overfoaming remains a critical challenge in industrial bioprocesses, compromising mass transfer, operational stability, and downstream efficiency in bioreactors and wastewater treatment systems. This study provides a bibliometric and scientometric assessment of nanoparticle‐enabled foam control to map technological trends and identify research

Isolation of the Volatile Oil from by Supercritical Carbon Dioxide Extraction: Chemical Composition and Biological Activity

open access: yesNatural Product Communications, 2011
Satureja thymbra L. is well known in Italy by the popular name of “Santoreggia sarda”. It grows only in Sardinia and nowadays it is restricted to the slope of the Colle San Michele in Cagliari.

The "True" Widom Line for a Square-Well System

open access: yes, 2014
In the present paper we propose the van der Waals-like model, which allows a purely analytical study of fluid properties including the equation of state, phase behavior and supercritical fluctuations.

Uphill Motion of Active Brownian Particles in Piecewise Linear Potentials [PDF]

open access: yes, 1999
We consider Brownian particles with the ability to take up energy from the environment, to store it in an internal depot, and to convert internal energy into kinetic energy of motion. Provided a supercritical supply of energy, these particles are able to
