Abstract The intense light–matter interaction of plasmonic metasurfaces provides an appealing platform for optical sensing. To date, most metasurface sensors are not spectrally tuned. Moreover, they operate in a total reflection mode, which complicates the setup. Transmissive tunable filters therefore desirable. A mid‐infrared (M‐IR) is described that operates transmission mode. resonant frequency filter tuned by nonvolatile phase transitions to dielectric properties chalcogenide material Ge...
Abstract Antiferromagnetic insulators are a ubiquitous class of magnetic materials, holding the promise low-dissipation spin-based computing devices that can display ultra-fast switching and robust against stray fields. However, their imperviousness to fields also makes them difficult control in reversible scalable manner. Here we demonstrate novel proof-of-principle ionic approach spin reorientation (Morin) transition reversibly common antiferromagnetic insulator α-Fe 2 O 3 (haematite) –...
Fourier transform-infrared (FT-IR) spectroscopy has gained considerable attention among the forensic scientists because it shows high sensitivity and selectivity offers near real time detection of analyzed samples. However, amount obtained information due to complexity measured spectra forces use additional data processing. Application multivariate statistical techniques for analysis FT-IR seems be necessary in order enable feature extraction, proper evaluation, identification spectra. In...
Abstract Separating enantiomers is vital in chemical syntheses, life sciences, and physics. However, the usual processes are inefficient. Recently, plasmonic nanostructures have drawn considerable attention for manipulating nanoparticles; however, only a few approaches proposed to discriminate between entities that differ terms of their handedness. This because chiral polarizability much smaller than electric polarizability, therefore non‐chiral gradient force dominates over force. limit...
As we live under a constant threat of global terrorism, the effective detection highly energetic materials is one critical procedures needed at variety locations, including airports, border checkpoints, and entrances to high-security buildings. In this work, application optical-photothermal infrared (O-PTIR) spectromicroscopy for explosive within fingerprints described. High-explosive (HE) (e.g., PETN, RDX, C-4, or TNT) were used prepare contaminated fingerprints. These subsequently...
The causes of prostate cancer are still obscure but some evidence indicates that there is a close connection between several trace elements and processes which may lead to malignant cells. In our study the microbeam synchrotron radiation X-ray fluorescence emission (micro-SRIXE) technique was applied for quantitative analysis selected elements. For first time, we correlate concentrations Mn, Fe, Cu, Zn with clinical stage at time operation (described by Gleason grade). Serial sections...
Synchrotron radiation-based Fourier transform infra-red (SR-FTIR) micro-imaging has been developed as a rapid, direct and non-destructive technique. This method, taking advantage of the high brightness small effective source size synchrotron light, is capable exploring molecular chemistry within microstructures microscopic particles without their destruction at spatial resolutions. in contrast to traditional "wet" chemical methods, which, during processing for analysis, often caused original...
Malaria, caused by parasites of the species Plasmodium, is among major life-threatening diseases to afflict humanity. The infectious cycle Plasmodium very complex involving distinct life stages and transitions characterized cellular molecular alterations. Therefore, novel single-cell technologies are warranted extract details pertinent Plasmodium-host cell interactions underpinning biological transformations. Herein, we tested two emerging spectroscopic approaches: (a) Optical Photothermal...
Lightweight nanocomposites reinforced with carbon nanotube (CNT) assemblies raise the prospects for a range of high-tech engineering applications. However, correlation between their heterogeneous chemical structure and spatial organization nanotubes should be clearly understood to maximize performance. Here, we implement advanced imaging capabilities atomic force microscopy combined near-field infrared spectroscopy (AFM-IR) analyze intricate CNT fiber-reinforced thermoset nanocomposites. As...
Dissolved organic carbon (DOC) is important to microbial activity and nutrient cycling, its concentration sensitive pH.

A survey 33 paddocks from Eyre Peninsula mid-North regions South Australia north-western Victoria demonstrated significant variation pH, C DOC. Carbon stocks...
ATR-FTIR (attenuated total reflection-Fourier-transform infrared) microscopy with imaging is widely used in the heritage field to characterise complex compositions of paint cross-sections. However, some limitations include need for ATR crystal contact sample and inability resolve particle size below IR diffraction limit.
