Petroleum reservoir simulation using super-element method with local detalization of the solution
Учёные записки Казанского университета: Серия Физико-математические науки, 2017 In this paper, we propose a two-stage method for petroleum reservoir simulation. The method uses two models with different degrees of detailization to describe the hydrodynamic processes of different space-time scales.

Surfactant-Polymer Interactions in a Combined Enhanced Oil Recovery Flooding
Energies, 2020 The traditional Enhanced Oil Recovery (EOR) processes allow improving the performance of mature oilfields after waterflooding projects. Chemical EOR processes modify different physical properties of the fluids and/or the rock in order to mobilize the oil

Geomechanical simulation of underground gas storage in a faulted reservoir: a case study in northern Italy [PDF]
, 2022 openUnderground gas storage (UGS) is a very common practice currently adopted to meet the growing energy demand, especially in North America and Europe. The gas is stored in reservoirs through a seasonal cycle of injection and removal.

Conformal Metallosaccharide Hybrid Films for Protecting Wood Surfaces From Environmental Damage
Advanced Functional Materials, EarlyView.Ti‐ribose hybrid films fabricated by molecular layer deposition form a conformal and uniform coating on wood surfaces, which provides water repellence, dimensional stability, and resistance to acidic and alkaline environments, while preserving the natural appearance.

Advanced Functional Materials, EarlyView.Redox dual‐defects (Cs substitution and O vacancies) in 2D hydrated WO3 steer O2 activation toward selective singlet oxygen evolution. WO‐CO achieves 8.6–15.8 times higher 1O2 production than single‐defect or pristine catalysts, enabling efficient pollutant mineralization via a pathway‐selective photocatalytic mechanism.

Advanced Functional Materials, EarlyView.Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale
