Summary: The study shows that external uniaxial strain can significantly reduce the energy barrier for water dissociation on the reduced rutile TiO2(110) surface, especially when the tensile strain is larger than 3%. Additionally, the mechanism of water dissociation changes under certain conditions, indicating the feasibility of engineering water dissociation on this surface using external strain.

Summary: This study investigates the photoinduced water dissociation and desorption on a R-TiO2(110) surface at different wavelengths, revealing significant increases in the relative yield of H2O oxidation and desorption as the laser wavelength decreases. The results suggest that the energy of charge carriers plays a crucial role in these processes and challenge the widely accepted photocatalysis model of TiO2.

Summary: We investigated the dynamics of charge transfer at the interface of water and anatase TiO2(101) using femtosecond time-resolved optical pump-soft x-ray probe photoemission study. Our observations, combined with molecular dynamics simulations, showed that ultrafast interfacial hole transfer from TiO2 to molecularly adsorbed water is completed within 285 fs. This is facilitated by the formation of a new hydrogen bond between an O2c site at the surface and a physisorbed water molecule. The efficient trapping of the hole at the TiO2 surface by hydroxyl species (-OH) before the hole transfer process was also suggested.

Summary: In this study, the crystal phase engineering of commercially available TiO2 catalyst was optimized to achieve high efficiency and selectivity in the oxidation of methane to formaldehyde under mild conditions. Experimental results and theoretical calculations revealed that crystal phase engineering prolonged the lifetime of photogenerated carriers and promoted the formation of intermediate methanol species, thus maximizing the efficiency and selectivity of formaldehyde production. Moreover, the feasibility of large-scale formaldehyde production was demonstrated by inventing a pause-flow reactor.

Summary: This study introduces a nanoetching technology to improve the photoelectrochemical (PEC) performance by exposing a large number of high-energy (101) crystal facets on rutile TiO2 nanorod films. The nanoetching technology significantly enhances charge separation and transfer efficiency, leading to improved PEC performance. The mechanism behind the enhancement is attributed to the reduced energy barrier for oxygen evolution reaction (OER) by shortening the distance between HO* intermediates on the rutile (101) facet and neighboring O-b. Additionally, the driving force for spatial charge separation between (110) and (101) facets promotes charge separation. This work offers a versatile nanotechnology for enhancing PEC performance.

Summary: This study investigated the effect of prolonged UV irradiation on the performance of superhydrophobized birch and acetylated birch wood. The results showed that the combination of surface modification using silicone nanofilaments and wood acetylation provided good wetting resistance even after prolonged UV exposure. Scanning electron microscopy images revealed that the silicone nanofilaments were still present on the wood samples after UV irradiation. Additionally, the surface-modified wood samples exhibited significant color change and degradation of lignin after UV exposure.

Summary: Small electron polarons were detected in rutile-TiO2 experiments, while only large ones were found in anatase. However, using an accurate hybrid functional, it was shown that the large polaron in anatase is actually of medium size and can be obtained in a static calculation. These states are two-dimensional in the (001) plane and can get trapped at the (101) surface, similar to the existence of small polarons. The calculated binding energy and the simulated scanning tunneling microscopic image matched well with experimental observations. The efficient separation of photoexcited carriers due to trapping of holes in small polaron states in the bulk and the presence of electrons only at the surface contribute to the excellent photocatalytic behavior of anatase.

Summary: A new deep hole-trapping site called 2Ti(6c)-O-br-O-Ti-5c on the rutile TiO2(110) surface has been discovered using many-body Green's function theory, potentially regulating the water photooxidation reaction. Introducing Ti vacancies into rutile to turn it into a p-type conductor may substantially increase the photooxidation efficiency by allowing direct dissociation of H2O at bridging oxygen vacancies.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
