Summary: The daily life of people in the intelligent age is inseparable from electronic devices, but the presence of bacteria on touch screens poses a threat to users' health. By synthesizing a photocatalytic TiO2/Ag thin film, the growth of bacteria can be effectively inhibited, and the film also exhibits excellent biocompatibility. This research not only provides a more convenient choice for traditional antibacterial methods, but also has great potential for application in the field of billions of touch screens.

Summary: Molybdenum oxide thin films were synthesized using plasma-enhanced atomic layer deposition, and the effect of plasma power on film structure was investigated. The film structure changed from orthorhombic phase to metastable monoclinic phase as the plasma power increased. Different grain morphologies were observed at different power levels, and the interfacial layer thickness was thinner at low powers. X-ray diffraction confirmed the presence of only +6 oxidation state of Mo in the films.

Summary: This work demonstrates controlled area-selective deposition of aluminum oxide phosphate (AlPO) at room temperature and near atmospheric pressure using a potentially zero-waste aerosol jet fog (ajFOG) deposition system. The process involves coating Octyl-trichlorosilane (OTS-8) self-assembled monolayers (SAMs) on SiO2/Si substrates, forming hydrophobic and hydrophilic regions through ultraviolet/ozone exposure, and selectively depositing AlPO onto the hydrophilic regions. Smooth films with sharp boundaries are achieved, with investigation into features and defects as a function of various parameters.

Summary: In this study, a corrosion-resistant microwave absorber was successfully prepared using an atomic layer deposition method. The composite material, consisting of 3D NiAl-layered double hydroxide/carbon nanofibers (NiAl-LDH/CNFs), demonstrated excellent microwave absorbing properties and strong corrosion resistance. The optimized NiAl-LDH/CNFs showed the strongest reflection loss and the widest effective absorption bandwidth, thanks to the cooperative effect of interfacial polarization loss, conduction loss, and three-dimensional porous structure. This work provides guidance for designing microwave absorbers that satisfy corrosion resistance.

Summary: The increasing demand for miniaturized devices has led to high importance and requirements for nanofabrication technologies that are of high-quality, low temperatures, and low cost. In recent years, the development of atomic layer deposition (ALD) processes has sparked interest in their use in advanced electronic and nano/microelectromechanical systems (NEMS/MEMS) device manufacturing. Non-thermal plasma (NTP) technology has emerged as a significant technique that expands the process window of ALD and allows the fabrication of various nanomaterials at lower temperatures, enabling the coverage of thermosensitive substrates with good formability and uniformity. This review article comprehensively describes the impact of NTP on the ALD universe and its applications in device fabrication. It also presents the integration of NTP and ALD technologies to form the plasma-assisted ALD (PA-ALD) technique, which has been successfully used in nanofabrication and surface modification. The advantages and limitations of this technique are discussed, along with the introduction of atomic layer etching (ALE) technique, another development of the NTP and ALD junction that has gained attention for plasma-assisted nanofabrication.

Summary: The global plastic waste is increasing due to the mass production and extensive use of surgical face masks during the COVID-19 outbreak. In order to address the environmental concerns, alternative face coverings are needed. This study developed electrospun nanofibrous mats (NM) using a renewable biopolymer, pullulan, and a naturally occurring essential oil compound, trans-cinnamaldehyde (CAH), in γ-cyclodextrin inclusion complexes (γ-CD-IC). These NM can be easily inserted into cloth masks and have higher loading efficiency compared to other mats. They also demonstrated good antibacterial activity, storage stability, thermal stability, and desirable properties such as pore size and water vapor permeability.
