Small, EarlyView.Screen‐printed mesoporous carbon perovskite solar cells offer an accessible route to scalable green energy. This study investigates the impact of dust particle contamination during the manufacture of this type of solar cell. Results suggest clean rooms may be unnecessary if strict cleanliness is maintained during storage and printing processes in ...

Treatment of saline produced water through photocatalysis using rGO-TiO 2 nanocomposites [PDF]
, 2018 Graphene like-TiO2 nanocomposites (rGO-TiO2) are prepared via hydrothermal route by following different synthetic protocols. The as-prepared nanostructured materials exhibit higher photocatalytic activity than bare TiO2 in the treatment of synthetic ...

Low‐Cost Ambient Pressure Drying Approach for Highly Porous Nanomaterial Structures
Small Methods, EarlyView.We propose a simple, low‐cost method to dry highly porous nanomaterial structures at ambient temperature and pressure. Using low surface tension solvents, this technique minimizes capillary forces, preventing pore collapse and material shrinkage. This bypasses the need for expensive and size‐limiting critical point drying, enabling scalable production ...

Electronic structures and optical spectra of thin anatase TiO2 nanowires through hybrid density functional and quasiparticle calculations [PDF]
, 2014 The electronic properties of quasi-one-dimensional anatase TiO2 nanostructures, in the form of thin nanowires having (101) and (001) facets, have been systematically investigated using the standard, hybrid density functional and quasiparticle ...

Environmental Toxicology, EarlyView.ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have

OPTICAL PROPERTIES OF ANODIC TITANIA AND IT'S APPLICATION IN MAXILLOFACIAL SURGERY
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019 Studying of anodic titania formation has showen that anodization forming factor at low anodic voltages is 3,3 nm/V, while at high anodic voltages it’s value decreases till 1,5 nm/V. The investigation of optical properties of anodic titania has showed the

Catalytic coatings on steel for low-temperature propane prereforming to solid oxide fuel cell (SOFC) application [PDF]
, 2009 Catalyst layers (4–20 lm) of rhodium (1 wt%) supported on alumina, titania, and ceria–zirconia (Ce0.5Zr0.5O2) were coated on stainless-steel corrugated sheets by dip-coating in very stable colloidal dispersions of nanoparticles in water.

Engineered surface strategies to manage dental implant‐related infections
Periodontology 2000, EarlyView.Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.
