Summary: Understanding the impact of side chains on the thermal transport of organic semiconductors is crucial in the field of functionalized organic electronics. In this study, phenyl and alkyl side chains were used to modify dinaphtho-[2,3-b:2 ',3 '-f]thieno[3,2-b]thiophene (DNTT), resulting in Ph-DNTT and C-10-DNTT. The thermal conductivities of the three organic semiconductors exhibited anisotropy, with the along-chain direction having the highest thermal conductivity. Phenyl side chains improved thermal transport in the along-chain direction but degraded it in the inter-chain direction, while alkyl side chains hindered thermal transport. Cross-chain thermal transport was minimally affected by side chains.

Summary: The study found that oxygen vacancy (V-O) defects can cause lattice distortion and carrier scattering, resulting in low carrier mobility in ITO. However, hydrogen doping can reduce the concentration of V-O, which accounts for the high carrier mobility in In2O3:H. Additionally, it was discovered that hydrogen overflows from the film at high temperatures (>250 degrees C), and acidic or alkaline environments can damage the In2O3 grains themselves. This work provides important insights into the mechanisms of high carrier mobility and stability in transparent conductive oxides.

Summary: Exosomes play a crucial role in intercellular communication, and the interaction between exosomes and traditional Chinese medicine (TCM) has beneficial effects on various diseases. TCM formulas and compounds can modulate exosomes to inhibit cell proliferation, reduce inflammation, and attenuate fibrosis. Additionally, exosomes serve as a natural delivery system for TCM compounds, and they may also be potential biomarkers for TCM syndromes.

Summary: Hall scattering factors of Sc2CF2, Sc2CO2 and Sc2C(OH)(2) were calculated using Rode's iterative approach in conjunction with calculations based on density functional theory. The study focused on the electrical transport in these MXenes, accounting for both elastic and inelastic scattering mechanisms. It was found that polar optical phonon scattering is the most significant mechanism in these materials. The observed variation in Hall factors could have significant implications for surface group identification in MXenes.

Summary: The study investigated the effect of pH on the entrapment and remobilization of external colloidal particles. It was found that permeability impairment due to external cake build-up can be reversed when the pH exceeds the point of zero charge of the hematite particles. This pH-controlled electrostatic retention and remobilization technique can be extended to other colloidal particles with pH-dependent surface charge.

Summary: The study investigates and classifies possible analytical solutions for a simplified foam bubble population model by varying injection conditions and kinetic foam generation parameter. The behavior of analytical solutions changes at the transition between two regions, with one region exhibiting traveling waves and the other region showing a sequence of waves: one spreading wave and one traveling wave. These findings differ from previous experiments.

Summary: Capillary forces trap oil in porous media even after flushing, but using polymer formulations can extract residual oil efficiently. However, the large quantity of chemicals used poses an environmental threat. This study demonstrates that using gases instead of polymers achieves equally efficient oil extraction with less chemical usage.

Summary: This study investigates the propagation and transport dynamics of nano-sized particles in subsurface water injection. Experimental and modeling approaches are used to explore the dispersion of silica nanoparticles and their agglomeration under different conditions. The results show that nanoparticles remain dispersed at low salinity and within a specific pH range, but agglomeration occurs at higher salinity, pH outside the range, or in the presence of iron ions. Core flood experiments demonstrate stable injectivity with proper pH and salinity of the injected fluid, but injectivity decline still happens and can be explained by a mechanistic model. This study contributes to a better understanding of nanoparticle transport dynamics and modeling prediction in subsurface applications.

Summary: Enhancing the recovery from existing oilfields is crucial due to increased energy demand. Polymer flooding, the most frequently used chemical enhanced oil recovery (cEOR) method, has gained growing interest in recent years. This is attributed to the improved properties of polymers at high-salinity and high-temperature conditions and an increased understanding of their transport mechanisms in porous media. Advanced water-soluble polymers and the viscoelastic behavior of polymers in porous media have shown promising results in cEOR applications.

Summary: This study aims to investigate the conditions for the formation of free gas bubbles in CO2-water mixtures and determine the bubble point pressure and rate of bubble formation through experiments and image analysis. The results show that there is a decent agreement between experimental results and theoretical predictions for CO2 in its gaseous state at moderate temperatures, but significant deviations are observed at elevated temperatures. More pronounced differences in bubble point are observed for mixtures starting out at high pressures where CO2 is a supercritical fluid.

Summary: One of the main objectives of foam flooding enhanced oil recovery (EOR) is to mobilize remaining oil in the reservoir after primary recovery and water flooding. This study investigates the impact of Newtonian and non-Newtonian viscosifying agents on foam flooding, and explores the potential use of glycerol as an economically and ecologically viable alternative to polymers. The experiments reveal that glycerol can achieve similar levels of mobility reduction as polymer solutions, and even reaches maximum mobility reduction faster.
