Coexisting Volatile and Nonvolatile Switching in 3D ALD‐IGZO Vertical RRAM for Fully Hardware‐Based Wide Reservoir Computing

Advanced Science, EarlyView.
A conformal ALD‐IGZO vertical RRAM integrates volatile and nonvolatile switching within a compact 2F architecture. Before forming, tunable volatile dynamics provide fading‐memory reservoir states, while after forming, stable multilevel conductance modulation enables hardware readout.

Triple‐Helix Biomolecules Construct Self‐Adaptive Multi‐Phase Interfaces for Dendrites Immunized Zinc Metal Anodes

Advanced Science, EarlyView.
A bio‐derived triple‐helix framework enables adaptive interphase engineering for aqueous Zn metal batteries. Directional Zn2+ migration channels and dynamic transformation into β‐sheet domains construct an optimized solid electrolyte interphase with flexible–rigid synergy, delivering dendrite‐free Zn deposition and exceptional long‐term battery cycling

PROTAC‐Engineered Protein/DNA Nanoantigen is a Potent Booster for Dendritic Cell Vaccines in Cancer Immunotherapy

Advanced Science, EarlyView.
A PROTAC‐functionalized protein/DNA‐integrated nanoantigen platform is developed to enhance dendritic cell vaccine potency. By combining a VHL‐recruiting peptide‐modified antigen with a sustained expression plasmid within CaCO3 nanoparticles, this system amplifies cross‐presentation, promotes DC maturation, and elicits robust Th1 and CTL responses ...

Experimental Study on the Physical Simulation of Water Invasion in Carbonate Gas Reservoirs

Applied Sciences (Switzerland), 2017
Water invasion in carbonate gas reservoirs often results in excessive water production, which limits the economic life of gas wells. This is influenced by reservoir properties and production parameters, such as aquifer, fracture, permeability and ...

A review of wettability alteration using surfactants in carbonate reservoirs

Advances in Colloid and Interface Science, 2021
The wettability of carbonate rocks is often oil-wet or mixed wet. A large fraction of oil is still remained in carbonate reservoirs, it is therefore of particular significance to implement effective methods to improve oil recovery from carbonate ...

EVOLUTION OF RESERVOIR SIMULATION FOR A LARGE CARBONATE RESERVOIR

Proceedings of Middle East Oil Show, 1989
ABSTRACT Reservof-1 is a large carbonate reservoir that was discovered and developed in the 1940's. A brief description of the reservoir and major events of the field development are presented. A 2D areal model was constructed for the reservoir in the 1970's. The use and the shortcomings of the model are discussed.

APPLICABILITY OF STEAMFLOODING FOR CARBONATE RESERVOIRS

Proceedings of SPE/DOE Enhanced Oil Recovery Symposium, 1980
Abstract Steamflooding can be a technically effective recovery method for carbonate reservoirs within certain parameter ranges. The attractiveness of steamflooding relates to the fact that heat conduction is a powerful mechanism for influencing the oil in the low permeability matrix in a heterogeneous formation, and the ...

Integration of multiscale carbonate reservoir heterogeneities in reservoir simulation

Journal of Petroleum Science and Engineering, 2013
Abstract The construction of robust reservoir models considering geological carbonate heterogeneities, such as fractures and vugs, upscaling and numerical flow simulation remains a challenge. This work performs a methodology aiming a suitable representation of flow simulation and upscaling techniques according to small and large scale carbonate ...

Carbonate Reservoir Description

International Petroleum Exhibition and Technical Symposium, 1982
Abstract Carbonate reservoirs are characterized by extremely heterogeneous porosity and permeability. These heterogeneities are caused by the wide spectrum of environments in which carbonates are deposited and by subsequent diagenetic alteration of the original rock fabric. Pore systems range from thick, vuggy reservoirs in the coarse-
