Article Abstract

Understanding NO chemistry at titania nanoparticle surfaces is important for photocatalytic environmental remediation processes. We focus on this problem and put forward an experimental-computational approach based on vibrational spectroscopy grounds. Temperature-dependent IR experiments of NO adsorption on shape-engineered nanoparticle (101) anatase surfaces are paired with power spectra obtained from Born-Oppenheimer trajectories. Then, the harmonic versus anharmonic vibrational frequencies of several adsorption scenarios are directly compared with the IR experiments. We conclude that molecules are adsorbed mainly by the N-end side and both the intermolecular interactions between adsorbed molecules and (NO) dimer formation are responsible for the main NO adsorption spectroscopic features. We also investigate the spectroscopy and the mechanism of formation on defective anatase surfaces of the long-lived greenhouse gas NO.

Residual antibiotics in the environment may pose threats to both ecological system and public health, necessitating the development of efficient analytical strategy for monitoring and control. This study proposes a photoelectrochemical extended-gate field-effect transistor (PEGFET) sensor for specific and sensitive detection of kanamycin. The sensor utilizes ITO glass as the extended gate electrode (photoelectrode) and titanium dioxide as the photosensitive material.

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.

Hydrogen sulfide (HS), carbonyl sulfide (COS), and dimethyl sulfide (DMS) are the primary sulfur compounds found in seawater, which cause pitting corrosion on the oxide passivation film of titanium, known as "the marine metals". In this study, density functional theory (DFT) was used to analyze the adsorption and surface electronic properties of these three small molecules on the anatase TiO(101) surface. The analysis was conducted through adsorption energy, work function, Mulliken charge population, and density of states (DOS).

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.
