Mechanisms of near‐normal sea water dolomitisation: Mesohaline‐reflux or syn‐depositional?

The Depositional Record, Volume 12, Issue 1, February 2026.
This study investigates the dolomitisation of the Eocene Dammam Formation on the Arabian Plate using petrographic, mineralogical, geochemical and isotopic analyses. The findings reveal two distinct dolomite types, formed primarily through normal‐to‐mesohaline sea water dolomitisation, challenging previous models such as sabkha‐meteoric mixing.

Systems‐Level Optimization of Hybrid Produced Water Treatment Systems for Sustainable Oil and Gas Production: A Review of Current Technologies

Global Challenges, Volume 10, Issue 2, February 2026.
ABSTRACT Produced water (PW) is the largest and most complex waste stream generated during oil and gas production, posing significant environmental, operational, and regulatory challenges due to its high salinity, dispersed hydrocarbons, toxic organics, heavy metals, and naturally occurring radioactive materials. Although numerous studies have reviewed

Minimum Shear Reinforcement for Reactive Powder Concrete Beams

Eng
The aim of this research was to determine the minimal requirements for shear reinforcement for reactive powder concrete (RPC) rectangular cross-sectional beams with a compressive strength of 157 MPa and a steel fiber volume content of 2.0% that remained ...

Study of cement-fly ash paste exposed to sodium sulfate solutions with different concentrations at different temperatures [PDF]

, 2010
When concrete elements are partially exposed to sulfate environment, in the upper part of concrete elements above ground an aquiferous zone containing almost saturated and high pH value (> 12.5) sulfate pore solution will be formed.

Abnormal Expansion Along the Synthesis of Zinc Stannate: A Way for Porous Ceramics Without Addition of Pore Generators

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
The abnormal expansion associated with the simultaneous synthesis and sintering of Zn2SnO4 from ZnO and SnO2 is due to the reaction mechanism and correlated with the conversion. This phenomenon opens the way to manufacture porous ceramics without the addition of pore generators, simplifying the process, and especially the thermal treatment.

Thixotropic and Mechanical Behavior of MgO–SiO2 Pastes Incorporating Rice Husk Ash for Extrusion‐Based 3D Printing

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT Rice husk ash (RHA) is an agricultural by‐product that can replace microsilica (MS) as a suitable silica source in MgO–SiO2 cement mixes, offering low‐carbon benefits. This study investigated the 3D printing properties, including thixotropy and hardened mechanical properties, of the MgO–SiO2 system formed by partial and total replacement of MS

From Local Biodiversity to Global Food Security: Antioxidant Evidence of Unconventional Edible Plants (2020–2025)

Journal of Food Process Engineering, Volume 49, Issue 2, February 2026.
This scoping review (2020–2025) compiles validated evidence on the antioxidant potential of unconventional edible plants (PANCs). Thirty species showed high phenolic content and strong radical‐scavenging activity, reinforcing their role as natural antioxidants and sustainable alternatives to synthetic additives within biodiversity‐based food systems ...

The regional evolution of a dryland fluvio‐aeolian and lacustrine succession in response to allocyclic forcing: insights from the Early Permian Cutler Group, Utah, USA

Sedimentology, Volume 73, Issue 2, Page 297-354, February 2026.
ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.
