Stabilization of Miscible Aqueous Phases via Diffusion‐Controlled Multifunctional Nanoparticle‐Ligand Complexation

Advanced Functional Materials, EarlyView.
This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

INNOVATIVE TECHNOLOGIES IN OIL RECOVERY OIL RECOVERY FROM BITUMINOUS SANDS

ETM - Equipment, Technologies, Materials, 2022
Bituminous sands are one of the main sources of alternative energy. However, the limited application of this method is associated with environmental and technical problems arising from the extraction of oil from bituminous deposits. In this paper, the authors propose a new environmentally friendly technology based on the application of nanoreagents for

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

Advanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Preface: The Second Generation of Second Amendment Law & Policy [PDF]

, 2010
Over 70% of China’s domestic oil production is obtained from nine giant oilfields. Understanding the behaviour of these fields is essential to both domestic oil production and future Chinese oil imports.

Effects of Molecular Designs and Double‐Network Morphologies for Bioadhesive Semiconductors

Advanced Functional Materials, EarlyView.
This study establishes molecular‐to‐mesoscale design rules for bioadhesive semiconducting polymers (BASCs). It identifies how side‐chain length, double‐network formation, and film thickness modulate adhesion strength and electronic performance, providing insight into the rational design of intrinsically adhesive semiconductors for stable and efficient ...

Synthesis of an efficient copolymer of acrylamide and acrylic acid and determination of its swelling behavior

Journal of Petroleum Exploration and Production Technology, 2018
The main purpose of this work is to prepare an efficient series of preformed particle gels (PPGs) and to study their behaviors to control unwanted water in oil fields. To this end, 12 copolymer samples composed of acrylamide and acrylic acid [poly(AAm-co-

4D‐Printed Magneto‐Plasmonic Microrobots for Programmable Spatiotemporal De‐Icing

Advanced Functional Materials, EarlyView.
A 4D‐printing strategy is introduced to achieve programmable de‐icing devices. By aligning gold–magnetite nanofillers within a photosensitive resin, the printed structures exhibit dual magnetic and plasmonic functionalities, enabling precise spatio‐temporal ice removal through thermoplasmonic effects.

Enhancing oil recovery of ultimate water-cut reservoirs with a novel methane-producing bacterial strain

Shiyou shiyan dizhi
Most of the old oil fields in eastern China are now in the ultra-high water-cut development stage characte-rized by a rapid increase in water-cut, low oil recovery rate and inefficient water flooding.
