Grazing incidence wide angle X-ray scattering measurements on aligned titanium oxide nanowires displaying anisotropic optical-electronic properties are carried out. Elemental and thermal analyses provide a chemical composition corresponding to HTiO·HO with ≈ 1 while the crystallographic data indicate a monoclinic cell with a lamellar substructure. Cell parameters are close to those of HTiO notwithstanding a doubling of the lattice in the layer plane. A comparison of the band gap energy values and the electronic transition modes between the two polymorphs displays differences that could be ascribed to the structural variation.

Despite the importance of the effect of subnanoscale roughness on contact line behavior, it is difficult to directly observe the local behavior of contact lines at the micro- and nanoscale, leaving significant gaps in our current understanding. In this research, we investigate contact line motions and their relationship with nanoscale surface topography using coherence scanning interferometry. Our experiments were conducted on the substrates with different wettability without changing nanoscale surface topography.

Glucose-dependent insulin delivery systems have been recognized as a promising approach for controlling blood sugar levels in individuals with diabetes mellitus (DM). Recently, titanium dioxide nanoparticles have garnered huge attention in scientific research for their small size and effective drug delivery capabilities. In this study, we developed alizarin (AL)-capped phenylboronic acid (PBA)-functionalized titanium dioxide nanoparticles (TiO) for glucose-sensitive insulin delivery (TiO-PBA-INS-AL) aiming to manage both blood sugar levels and its associated organ pathology in DM.

Protein phosphorylation is an important post-translational modification that regulates almost all cellular processes, such as cellular metabolism, growth, differentiation, signal transduction, and gene regulation. Mass spectrometry, which acts as an automated and sensitive method, enables global analysis of protein phosphorylation. However, several technical challenges need to be addressed when analyzing protein phosphorylation in a global manner.

The fungus Candida albicans is a prominent cariogenic fungal agent that works in association with Streptococcus mutans to accelerate the formation of oral cancer and tooth decay. This study evaluates caffeine-encapsulated titanium oxide nanoparticles (CF-TiO2 NPs) for their potential to prevent biofilm formation on teeth and enhance oral anticancer treatment by influencing apoptotic gene regulation. The synthesized CF-TiO2 NPs were characterized using UV, SEM, EDAX, and FTIR analyses, and their antioxidant activity was confirmed through free radical quenching studies.

Exposure to high temperatures during indoor and outdoor activities increases the risk of heat-related illness such as cramps, rashes, and heatstroke (HS). Fatal cases of HS are ten times more common than serious cardiac episodes in sporting scenarios, with untreated cases leading to mortality rates as high as 80%. Enhancing thermal comfort can be achieved through heat loss in enclosed spaces and the human body, utilizing heat transfer mechanisms such as radiation, conduction, convection, and evaporation, which do not require initial energy input.
