A Tellurium Oxide Microcavity Resonator Sensor Integrated On-Chip with a Silicon Waveguide

open access: yesSensors, 2018
We report on thermal and evanescent field sensing from a tellurium oxide optical microcavity resonator on a silicon photonics platform. The on-chip resonator structure is fabricated using silicon-photonics-compatible processing steps and consists of a ...

Borosulfates Hosting Se42+ Ions—Crystal Structures, Chemical Bonding, Optical Spectroscopy, and Magnetism

open access: yesAngewandte Chemie, EarlyView.
Apart from (transition) metal (oxo)halides only few hosts stabilize chalcogenide cations in purely oxoanionic coordination environment. Herein, we report on five borosulfates containing the Se42+ ion and characterize the compounds using X‐ray diffraction, diffuse reflectance spectroscopy, density functional theory (DFT) calculations along with magnetic

Pressure‐Tuned Superconducting Dome and Persistent Charge‐Density‐Wave Order in NdSeTe2

open access: yesAdvanced Science, EarlyView.
NdSeTe2 exhibits an unusual pressure‐tuned phase diagram in which charge‐density‐wave order does not disappear at optimal superconductivity. Instead, Raman spectroscopy reveals a transformation from long‐range to short‐range correlations that remain invisible to resistivity and persist across the entire superconducting dome.

Fast Programming of in‐Plane Hyperbolic Phonon Polariton Optics through Van der Waals Crystals Using the Phase‐Change Material In3SbTe2

open access: yesAdvanced Science, EarlyView.
Launching structures for in‐plane hyperbolic polaritons in α‐MoO3 are optically programmed through already deposited flakes into the phase‐change material In3SbTe2. Precise alignment with the flake's crystal axes, focusing of polaritons by an optically programmed disk, and a first experimental realization toward a nanocavity for in‐plane hyperbolic ...

Supramolecular Chiral Assemblies from Benzoselenadiazole‐Alanine‐Acylhydrazone Conjugates Enable Cardioprotection

open access: yesAdvanced Science, EarlyView.
The C3‐symmetric conjugate TASe, which integrates benzoselenadiazole, alanine, and acylhydrazone modules, self‐assembles into a chalcogen‐/hydrogen‐bonded porous framework in the solid state and uniform chiral nanospheres in aqueous media. These assemblies protect cardiomyocytes from doxorubicin‐induced oxidative injury by scavenging intracellular ...

Spatially Confined/Ligand‐Directed Ultrabright NIR‐AIE Nanoprobe for In Vitro Rapid Detection and In Situ Imaging of Bacterial Septic Arthritis

open access: yesAdvanced Science, EarlyView.
Inorganic PbS quantum dots spatially confine AIEgens and enable cooperative luminescence within a ligand‐directed core–shell–shell nanoassembly, generating ultrabright NIR PPANPs with enhanced fluorescence and photothermal performance. The platform enables 10‐min S.

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

open access: yesAdvanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Tellurum-bismuth mineralization in ores of the Maleevskoe pyrite deposit (Eastern Kazakhstan)

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов
As it is known, Rudny Altai is a classic province of sulfide deposits, most of which were formed in paleo-island-arc geodynamic settings. Pyrite ores have a complex and diverse chemical composition, including a wide range of impurity elements, among ...
