Summary: Liquid crystals (LCs) are promising materials for the fabrication of reconfigurable arrays of 2D nanomaterials. However, achieving stable dispersions of nanomaterials in LCs is challenging. In this study, good dispersions of pristine CdSe nanoplatelets (NPLs) in LCs were achieved, and their alignment and associated photoluminescence could be controlled by a magnetic field. The dispersion stability was greatly enhanced using polymeric LCs, and the stability was higher in the smectic phases compared to the nematic phases. The aligned composites exhibited highly polarized emission that could be manipulated by field-realignment, which can have applications in programmable materials for photonics.

Summary: In this study, Multi-walled carbon nanotubes (MWCNTs) were decorated with bile juice-mediated copper nanoparticles synthesized using a green method. The antimicrobial activity of BJ-Cu@MWCNT was evaluated against S. aureus and P. aeruginosa, with minimum inhibitory concentration (MIC) values of 24 and 16 mu g/mL, respectively. Extensive experiments were conducted to explore the mechanism of bacterial death. The synthesized nanomaterial also showed excellent antibiofilm properties against the same bacterial strains. The findings suggest that the synthesized nanomaterial could be a potent antibacterial and antibiofilm agent against pathogenic Gram-negative and Gram-positive bacteria.

Summary: The non-covalent biomolecular functionalization of fluorescent single-walled carbon nanotubes (SWCNTs) has led to their extensive use in in vitro and in vivo sensing and imaging applications. However, it has been observed that these SWCNTs tend to aggregate in protein-containing environments before interacting with cells at the nanobiointerface. This study shows that initially aggregated SWCNTs do not further accumulate within subcellular locations and that SWCNTs with a low degree of aggregation can induce significant deleterious effects on cells.

Summary: Hydrophobic functionalized carbon nanotubes (fCNTs) and silica nanoparticles (fSiO(2)NPs) were added to polyvinylidene fluoride (PVDF) flat-sheet membranes to improve their performance in membrane distillation (MD). The incorporation of fCNTS and fSiO(2)NPs improved the water contact angle (WCA) and liquid entry pressure (LEP) of the PVDF membrane, as well as the membrane surface roughness. This resulted in high salt rejection and stable fluxes in the MD process.

Summary: This study experimentally determined the viscosity and electrical conductivity of MWCNT-Fe2O3 nanofluids based on DIW, and found that hybrid nanofluids have superior performance compared to conventional fluids. High volume concentrations significantly increased the electrical conductivity and viscosity of the hybrid nanofluids, while also exhibiting high stability. The lower viscosity of the hybrid nanofluid compared to mono-particle nanofluids of Fe2O3/water is advantageous for engineering applications as it reduces pumping power.

Summary: We investigated the electromigration forces for weakly bonded adsorbates on graphene using density-functional based calculations. The results showed that the nature of electromigration forces depends critically on the energy level alignment between the adsorbate state and the Fermi level of the graphene. For resonant adsorbates, the electromigration force is dominated by the electron wind force, while for nonresonant adsorbates, it is essentially the direct force dependent on the adsorbate charge. Moreover, we demonstrated that the magnitude of electromigration forces can be continuously adjusted through electrostatic gating for resonant adsorbates.

Summary: This paper introduces a method to control the orientation of polymer nanocomposites using dynamic covalent bonds and nanorods as fillers. Through simulation studies, it is found that the main factors affecting nanorod orientation are network rearrangement and interfacial interaction strength.

Summary: Above a critical diameter, carbon nanotubes collapse into flattened forms, leading to unique Raman spectra changes. The presence of edge cavities and curvature changes near the edges activate a D band despite overall continuity in the structure. The differing perspectives of chemists and physicists on defects in carbon structures may lead to confusion for researchers in nanotechnologies.

Summary: A new method called ultraviolet-triggered surface catalytically initiated radical polymerization (UV-SCIRP) from a sticky initiation layer (SIL) has been proposed for growing hydrogel coatings on substrates/medical devices. This method allows for the modification of virtually any substrate's surface with controllable thickness and diverse compositions of hydrogel coatings. The hydrogel coatings exhibit good interface bonding with the substrates and enable easy changes in their wettability and lubrication performances. Importantly, this method facilitates the smooth growth of uniform hydrogel lubrication coatings on the surface of a range of medical devices with complex geometries.

Summary: In this study, the hygroscopicity of polyurethane foams with different compositions was investigated. The experimental results showed that the moisture absorption of the foams followed Fick's law, and the mechanical properties of the foams were slightly reduced after moisture absorption. PU-4 was identified as the optimal foam system based on its dimensional and mechanical property changes. Additionally, it was found that moisture absorption increased significantly with higher temperature and humidity. Two-dimensional infrared and NMR techniques revealed the moisture absorption mechanism at the molecular scale, which was validated by molecular dynamics simulations.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
