Summary: A study was conducted to investigate the complexation ability between polyethylene oxide-polypropylene oxide triblock polymers and gold nanoparticles. It was found that linear block polymer pluronics had stronger association with gold nanoparticles compared to star shaped tetronics. The difference was attributed to the molecular structures and adsorption modes of pluronics and tetronics on the solid-liquid interface of gold nanoparticles. This research highlights the importance of the complexation ability of biologically active water soluble polymers with nanoparticles in various biological applications where gold nanoparticles are commonly used as markers or drug delivery vehicles.

Summary: Contrast variation in SANS was applied to localize anionic azo dye Blue in co-assemblies with cationic surfactant DTAB. Contrast matching eliminated the scattering contrast between DTAB and solvent, leaving only the signal from Blue. Results were confirmed by NOESY NMR-spectroscopy, showing interactions between Blue and DTAB and explaining the growth of DTAB micelles. The complementary use of SANS contrast matching and NMR-spectroscopy allows for the unambiguous localization of anionic dye in DTAB micelles.

Summary: Nanoparticles are commonly added to polymer electrolytes to enhance their mechanical and ion transport properties. This work carefully controls the dispersion state of silica nanoparticles in a model polymer electrolyte system and finds that controlling the dispersion leads to improved mechanical properties while reducing the ionic conductivity. These results suggest that achieving increases in bulk, ionic conductivity requires percolating aggregates of ceramic surfaces.

Summary: Polymerization-induced self-assembly (PISA) is a powerful method to produce polymeric nano-objects in (aqueous) solution. The mechanisms involved in morphological transitions during PISA are still not well understood. Through a systematic study, it is found that unimer exchange is not necessary for the formation of higher order morphologies in PISA, and the monomer present in the polymerization medium is responsible for the morphological transitions.

Summary: The behavior of microgels depends on particle concentration, which is different from hard particles. The presence of charged groups on microgels and the associated counterion cloud are responsible for the spontaneous deswelling of microgels in concentrated suspensions. However, there is no direct measurement of this counterion cloud.

Summary: Chain exchange in amphiphilic block polymer micelles can be measured using time-resolved small-angle neutron scattering (TR-SANS). However, analyzing chain mixing during micelle transformations on short time scales is challenging due to low data statistics. A new approach called shifting references relaxation (SRR(t)) is proposed, which enables the calculation of mixed states regardless of short acquisition times by acquiring reference patterns at each time point. SRR(t) is compatible with arbitrary levels of complexity and can accurately assess the mixed state, supporting future model analysis.

Summary: In an attempt to address the limitations of the currently available marketed formulation of exemestane, a study was conducted using a lamellar liquid crystal based formulation for topical application. Results showed that the formulation exhibited gel-like properties at low shear rate, transitioning to a flowing liquid at higher shear rate. This alternative route of drug delivery may offer improved bioavailability of exemestane due to enhanced solubility, permeability, and absorption.

Summary: By grafting malic acid onto the surface of Fe3O4, we designed highly water-dispersible Fe3O4 magnetic nanoparticles with good aqueous colloidal stability, pH-dependent surface charge characteristics, and superparamagnetic behavior. The optimized electrostatic conjugation of drug onto MMNCs surface achieved a maximum loading efficiency of 72%, resulting in pH-dependent controlled release characteristics and dose-dependent cellular uptake of DOX-MMNCs, showing considerable toxicity towards breast cancer cells. Additionally, our magnetic hyperthermia studies demonstrated the excellent heating efficiency of the MMNCs for safe application in hyperthermia therapy.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
