A Needle in a Haystack: Landscape Survey and Archaeological Detection Experiments in Apalachee Bay

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This paper presents the results of a pilot landscape‐scale seismic survey undertaken in Apalachee Bay, Florida, across a submerged landscape that contains dozens of Pre‐Contact sites. In addition to the goals of improving the geophysical and remote sensing ground model for this submerged landscape, the survey also sought to undertake the first

Waste Management and Waste Disposal Detected by Combination of Analytical Methods: Late Bronze Age Březnice Settlement Site (South Bohemia)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Waste disposal processes and landfill management are crucial subjects in the field of settlement archaeology. Our study is focused on understanding the processes that are connected to the formation of the infills of settlement features and the recycling of the building materials (daub and wood) and waste management.

A simulation study of hydraulic fracturing design in carbonate reservoirs: a middle east oilfield case study

open access: yesJournal of Petroleum Exploration and Production Technology, 2022
The interactions between hydraulic fracture morphology and fluid transport mechanisms after large-scale fracturing in low-permeability carbonate reservoirs are important factors that could impact post-fracturing productivity.

Robust Self‐Healing Metallo‐Supergels of Folic Acid: Potential Sustainable Gelator for Oilfield Applications

open access: yesChemistry – A European Journal, EarlyView.
In combination with a large group of various metal salts folic acid (FA) forms mechanically robust metallogels with rapid recovery and self‐healing properties. These versatile gel systems provide tunable stiffness, with up to 95% of stiffness restored within 1 min.

Weighing risks against GHG reduction benefits in emerging green technologies

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Green technologies represent promising strategies for mitigating carbon emissions and combating global warming. However, their implementation in civil and industrial applications is not without risks, as intrinsic uncertainties and latent safety concerns can threaten their effective deployment.

Rethinking Chlorine: Essential Chemical or Replaceable Risk?

open access: yesChemSusChem, Accepted Article.
This review critically examines the dual nature of chlorine as both an indispensable base chemical and a potential risk. Chlorine and its by‐product hydrogen chloride play essential roles in the production of pharmaceuticals, plastics, agrochemicals, and disinfectants.

Determining the REV for Fracture Rock Mass Based on Seepage Theory

open access: yesGeofluids, 2017
Seepage problems of the fractured rock mass have always been a heated topic within hydrogeology and engineering geology. The equivalent porous medium model method is the main method in the study of the seepage of the fractured rock mass and its ...
