Measurement of Nonplanar Dielectric Samples Using an Open Resonator [PDF]

open access: yes, 1987
Conventional microwave methods for measuring permittivity often utilize samples in flat sheet form. In practice, however, it is sometimes desirable to measure samples having curved surfaces, for example, parts of lenses or small radomes.

Utilization of Poly(methyl Methacrylate) Rejection Blended with Acrylonitrile Butadiene Styrene Resins and the Effect on Product Properties [PDF]

open access: yes, 2016
PMMA is one of the main raw materials for the injection molding process in the lens industries. Since this process requires extremely careful techniques to obtain lens with the best quality, it leads to a high rate of product rejection.

Biofilm Control by Active Topography with Mucin Coating

open access: yesAdvanced Functional Materials, EarlyView.
This study reports a new antifouling strategy based on a bioinspired design. Mucin coating enhances biofilm control by active topography with beating micron‐sized pillars. Besides the mechanical force of beating pillars, the antibiofilm activities also involve biological factors since mucin coating inhibits swarming motility and c‐di‐GMP synthesis in ...

Multi‐Pathway Upconversion Emission in Symmetry‐Broken Nanocavities: Broadband Multiresonant Enhancement and Anti‐Correlated Interfacial Sensitivity

open access: yesAdvanced Functional Materials, EarlyView.
Symmetry‐broken plasmonic nanoantenna arrays achieve broadband multiresonant enhancement of second harmonic generation (SHG), third harmonic generation (THG), and upconversion photoluminescence (UCPL), under femtosecond laser excitation across the near‐infrared range (1000–1600 nm).

H2O2‐Generating Advanced Nanomaterials for Cancer Treatment

open access: yesAdvanced Functional Materials, EarlyView.
H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

Cement cardiac embolism following kyphoplasty noted on thoracic imaging

open access: yesRadiology Case Reports, 2018
Asymptomatic polymethyl methacrylate cardiac embolism is an uncommon complication of kyphoplasty. We report a case of a 56-year-old female with an incidentally noted radiopaque foreign body in the right ventricular cavity on chest x-ray following ...
