Summary: The effect of silica nanoparticles (NP-SiO2) in xanthan gum (XG) solutions was investigated in this study. The addition of nanoparticles showed a slight effect on the viscosity of the fluids, which became more remarkable over time. Interfacial tension tests measured in water-mineral oil systems did not find any effect on the interfacial properties with the addition of polymer or nanoparticles. Three core flooding experiments were conducted using sandstone core plugs and mineral oil, and the nanofluid formulation recovered about 13% of the residual oil, almost double that of the original XG solution.

Summary: The study investigates the structural and rheological properties of a partially hydrolyzed polyacrylamide (FLOPAAM 3630S) in a wide range of salinity relevant to existing oil reservoir conditions. It is found that macromolecular solutions are present at low polymer concentrations and/or elevated salt levels, while gelation occurs at high FLOPAAM 3630S doses at low salinity. The driving force behind this transformation is determined to be hydrophobic intermolecular interactions. These findings provide new insights for the design of efficient enhanced oil recovery processes in oil reservoirs with varying salt levels.

Summary: In this study, a thermally stable and salt tolerant biopolymer (HS-EPS) was obtained from the broth of Sphingomonas sp. HS. The HS-EPS showed good viscosity stability, and in combination with a biobased surfactant, a new alkali-free surfactant-polymer binary system was developed. This system exhibited low interfacial tension with crude oil and demonstrated good adsorption resistance, dilution resistance, and aging stability.

Summary: The adsorption of hydrolyzed polyacrylamide on carbonate surface was investigated by molecular dynamic simulation and experimental procedure, showing that polymer adsorption decreased the water contact angle, resulting in a moderately oilwet state and good agreement with experimental results. This opens up opportunities for further molecular dynamic investigations of different polymers as wettability modifiers during EOR processes.

Summary: This study investigates the behavior of HPAM molecules at the crude oil-water interface. The results show that HPAM molecules aggregate in different forms, and the inorganic cations have an impact on the aggregation. The stability of the interfacial film is correlated with the gyration radius of the HPAM molecules, and the effect of hydrolysis degree on stability is within a certain range.

Summary: This study reports on the deployment of MEMS static bifurcation sensors for the detection of volatile organic compounds, specifically hydrogen sulfide and formaldehyde. The sensitivity and selectivity of two detector polymers, polyaniline (PANI) and poly (2,5-dimethyl aniline) (P25DMA), were investigated. A semi-automatic method was developed to functionalize individual sensors and arrays with the detector polymers. The results show that the sensor array can selectively detect 1 ppm of formaldehyde in the presence of benzene.

Summary: The study evaluated the sensitivity of polyaniline and its derivative poly (2,5-dimethyl aniline) towards formaldehyde, with polyaniline showing higher sensitivity. Doping polyaniline with different weight percentages of indium oxide was found to enhance sensitivity towards formaldehyde, with 1.25 wt% In2O3 yielding the highest sensitivity. Additionally, different weight percentages of In2O3 resulted in reversed trends for sensitivity and selectivity, with all sensing materials being stable.

Summary: Packaging material plays a crucial role in maintaining or changing the shelf life of products. This study focuses on developing a new polymer composite for packaging. The composite consists mainly of nonacosan-10-ol and polyethylene, aiming to address the challenge of controlling oxygen diffusion rates during the storage of perishable goods. Molecular dynamics simulations are conducted to assess the impact of different weight percentages of nonacosan-10-ol on polyethylene in terms of mechanical and gas transport properties. The optimal composition of the proposed additive is suggested based on minimal oxygen diffusion rate, high elastic modulus, and good thermal stability.
