Joint detection of tumor markers with imaging ellipsometry biosensor

open access: yes, 2014
Tumor marker detection contributes to the early diagnosis of cancers. However due to the lack of detection specificity its results cannot act as a direct evidence to confirm cancer occurrence in clinic.

Ultra‐High‐Throughput Discovery of Multifunctional Polyphenolic Coatings on Droplet Microarrays

open access: yesAdvanced Materials, EarlyView.
An ultra‐high‐throughput (UHT) combinatorial strategy enables the miniaturized synthesis and screening of ≈30 000 polyamine‐polyphenolic (PaPp) coatings using droplet microarrays (DMA). This approach reveals hundreds of previously unknown fluorescent, redox‐active, and antibacterial materials, including multifunctional, cell‐compatible surfaces ...

Transient dielectric function dynamics driven by coherent phonons in Bismuth crystal

open access: yesJournal of the European Optical Society-Rapid Publications
In this study, we investigate the ultrafast transient dynamics of the dielectric function in bismuth crystal, excited by femtosecond laser pulses and modulated by coherent phonons. The primary aim is to understand the influence of the coherent A1g phonon

Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum

open access: yesAdvanced Materials, EarlyView.
Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...

Atomic Layer Deposition of Metallic Molybdenum Dioxide Thin Films Enabling High‐k Rutile Capacitors

open access: yesAdvanced Materials Interfaces, EarlyView.
The first direct atomic layer deposition (ALD) process of molybdenum dioxide (MoO2) thin films is reported using molybdenum(II) acetate dimer (Mo2(OAc)4) and oxygen (O2) as precursors at 235°C–275°C. The films are crystalline, exceptionally pure, and conductive.

Layered Nanoporous Platforms for SERS Sensing

open access: yesAdvanced Materials Interfaces, EarlyView.
Here, we present a detailed investigation of the SERS performance of layered nanoporous metals. The controlled deposition of well‐defined, stacked porous layers enabled a systematic analysis of the effects of multimetallic systems in SERS experiments. Numerical models are also used to support the experimental findings.

Vertical-Objective-Based Ellipsometric Microscope for Real-Time Observation of nm-Thick Lubricant Films

open access: yesTribology Online, 2012
The vertical-objective-based ellipsometric microscope (VEM) is expected to be a useful method for clarifying the lubrication phenomena that uses thin liquid lubricants, especially the lubricant for hard disk drives (HDDs). Although the feasibility of VEM

Organic LEDs Based on Bis(8-hydroxyquinoline) Zinc Derivatives with a Styryl Group

open access: yesMolecules, 2023
For the first time, organic light-emitting diodes (OLEDs) based on bis(8-hydroxyquinoline) zinc with a styryl group (ZnStq) dispersed in poly(N-vinylcarbazole) matrix (ZnStq_R:PVK, where R = H, Cl, OCH3) were fabricated.
