The Chemistry of Paints and Painting. [PDF]

open access: yesNature, 1892
CONSIDERING the widespread interest which attaches to all matters connected with pictures and painting, it is perhaps somewhat surprising that up to within quite recent times no attempt has been made to discuss and review in a comprehensive and efficient manner the materials and methods of painting from a strictly chemical point of view.

Methods for the detection and characterization of boat paint microplastics in the marine environment

open access: yesFrontiers in Environmental Chemistry, 2023
Microplastics in the marine environment have been the focus of intense research recently, however little attention has been given to boat paint sources, despite its direct influence on the marine ecosystem.

Case Report: Two Cases of Salivary Duct Carcinoma in Workers With a History of Chromate Exposure

open access: yesFrontiers in Medicine, 2021
Background: Salivary duct carcinoma (SDC), one subtype of the 22 different salivary gland cancers, is a rare malignancy. Risk factors for the development of salivary gland cancer and SDC are largely unknown, although pollution has been described as one ...

Inactivation and spike protein denaturation of novel coronavirus variants by Cu x O/TiO2 nano-photocatalysts

open access: yesScientific Reports, 2023
In order to reduce infection risk of novel coronavirus (SARS-CoV-2), we developed nano-photocatalysts with nanoscale rutile TiO2 (4–8 nm) and Cu x O (1–2 nm or less). Their extraordinarily small size leads to high dispersity and good optical transparency,

Single- and Multi-Element Quantification and Characterization of TiO2 Nanoparticles Released From Outdoor Stains and Paints

open access: yesFrontiers in Environmental Science, 2020
With growing applications of TiO2 nanoparticles (NPs) in outdoor surface coatings, notably in paints and stains, their release into the environment is inevitable.

High-Speed Super-Resolution Imaging Using Protein-Assisted DNA-PAINT

open access: yes, 2020
Super-resolution imaging allows for the visualization of cellular structures on a nanoscale level. DNA-PAINT (DNA point accumulation in nanoscale topology) is a super-resolution method that depends on the binding and unbinding of DNA imager strands.

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures

open access: yesAdvanced Engineering Materials, EarlyView.
We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

open access: yesAdvanced Engineering Materials, EarlyView.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Multiplexed and Millimeter-Scale Fluorescence Nanoscopy of Cells and Tissue Sections via Prism-Illumination and Microfluidics-Enhanced DNA-PAINT

open access: yes, 2023
Fluorescence nanoscopy has become increasingly powerful for biomedical research, but it has historically afforded a small field-of-view (FOV) of around 50 μm × 50 μm at once and more recently up to ∼200 μm × 200 μm. Efforts to further increase the FOV in
