Summary: Understanding the relationship between cellulose fiber morphology and the rheological behavior of its dispersions is important for optimizing their applications. Sugarcane bagasse-sourced cellulose dispersions with different numbers of high-pressure homogenization cycles were produced. Microfluidization produced cellulose nanofibers with similar surface charge densities and crystallinities. The rheological properties of the dispersions could be tuned by adjusting the length of the nanofibers, allowing for targeted applications.

Summary: Cellulose aerogels have the potential to be alternatives to silica aerogels with advantages in cost, sustainability, and mechanical properties. However, the density dependence of thermal conductivity for cellulose aerogels remains controversial. Experimental results show that the density of cellulose aerogels affects the thermal conductivity, with compressed aerogels having lower thermal conductivity due to the alignment of nanofibers.

Summary: Cellulose nanofiber (CNF) nanopapers from garlic skin were impregnated in various concentrations of polyimide (PI) solution. The resulting CNF/PI composite nanopapers showed lower Young's modulus and tensile strength, but higher toughness and elongation compared to the original CNF nanopapers. The impregnation of nanopapers in PI solution not only led to the formation of smaller pores and limited pore size distribution, but also increased the BET-specific surface area, resulting in superior filtration capacity and a higher quality factor (QF). Composite materials prepared by impregnation with 5% wt PI showed the most promising potential to be developed as air filters, with flexibility, superior filtration efficiency (99%), and a higher QF than commercial filters.

Summary: The magnetization of Zn1-xCoxO (0.0055 <= x <= 0.073) nanoparticles was measured as a function of temperature and magnetic field. The magnetic properties were found to be derived from the antiferromagnetic spin clustering of Co2+ nearest-neighbors. The magnetization curves showed a deviation from the expected behavior below 6 K, which was successfully explained by a model based on single-ion anisotropy and randomly oriented nanoparticles.

Summary: This study characterized the ultrastructure and morphology of TiO2 nanotubes and investigated their physicochemical impact on high-viscosity conventional glass-ionomer cement (GIC). The results showed that TiO2 nanotubes were present in the GIC matrix, leading to changes in radiopacity, solubility, and color. However, the setting time of GIC was not affected by the presence of TiO2 nanotubes. These findings provide important information on the potential benefits of using TiO2 nanotubes in dental materials.

Summary: The purpose of this study was to analyze the physical-chemical properties of hydrogen peroxide (HP) agents at different concentrations and the association with or without TiO2 nanotubes. The study also aimed to evaluate dental bleaching effectiveness by using the HP agents together with or without TiO2 nanotubes, and applied with or without violet LED (VL). The results showed that the incorporation of TiO2 to the bleaching gel showed good stability with minimal variations in physical-chemical properties. HP35 had a more effective color change compared to HP7, and VL boosted the bleaching effectiveness of HP7, whereas TiO2 did not increase bleaching effectiveness.

Summary: This study aims to evaluate the transport properties and CBZ adsorption capacities of PES/mesoparticles-based MMMs in aqueous solutions with different physicochemical characteristics. The results show that PES/SH-MCM-41-based MMMs have the highest potential for CBZ adsorption. The multivariate design results indicate that contact time, initial CBZ concentration, and the amount of SH-MCM-41 incorporated in MMM significantly influence the adsorption capacity, while pH does not affect it. Water permeability tests show a correlation between the H2O permeability and the porosity of the synthesized membranes. PES/SH-MCM-41-based MMMs exhibit high porosity and good ability to remove CBZ from water, regardless of the pH of the aqueous solutions.

Summary: An experimental setup was designed and assembled to evaluate the permeation of gaseous species and collect electrochemical impedance spectroscopy data in disk-shaped ceramic membranes. The setup consisted of an alumina sample holder with thermocouple tips and platinum electrodes located close to both sides of the sample. Gas permeation through a ceramic membrane was monitored using mass flow controllers, a mass spectrometer, and an electrochemical impedance analyzer. Ceramic composite membranes were prepared with the infiltration of molten eutectic compositions of alkali salts into porous gadolinia-doped ceria for testing and data validation. Values of the alkali salt melting points and the permeation rates of carbon dioxide, in agreement with reported data, were successfully collected.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
