Advances in Magnesium‐Based Thermoelectrics: A Critical Review

open access: yesAdvanced Materials, EarlyView.
Magnesium‐based thermoelectric materials have emerged as promising candidates for low‐to‐mid‐temperature energy conversion due to their abundance, low cost, and competitive performance. This review summarizes recent advances in Mg3X2, MgAgSb, and Mg2X systems, covering transport mechanisms, fabrication strategies, stability challenges, and device ...

Label-free real-time acoustic sensing of microvesicle release from prostate cancer (PC3) cells using a Quartz Crystal Microbalance

open access: yes, 2014
Using a Quartz Crystal Microbalance with dissipation monitoring, QCM-D (label-free system) measuring changes in resonant frequency (Δf) that equate to mass deposited on a sensor, we showed the attachment, over a 60 min period, of a monolayer of PC3 cells

Second‐Harmonic Hyper‐Mie Optical Activity Enables Closed‐Loop Chiral Photochemistry

open access: yesAdvanced Materials, EarlyView.
Nonlinear chiral photochemistry is demonstrated in CdTe/CdO nanohelices, where circularly polarized infrared light both drives and tracks photo‐oxidation via second‐harmonic scattering. This closed‐loop process reveals real‐time structural evolution, including shell fracturing and core exposure, accompanied by a transition from hyper‐Mie to hyper ...

Co1/Ru Single‐Atom Alloy Catalyst for Sustainable Polypropylene Hydrogenolysis to Long‐Chain Liquid Products

open access: yesAdvanced Materials, EarlyView.
A titania‐supported Co1/Ru single‐atom alloy catalyst enables efficient polypropylene hydrogenolysis. Ru─Co─Ru motifs maintain Ru activity while suppressing excessive chain scission to gaseous products. Both virgin and waste plastics achieve high, environmentally and economically optimal C11+ liquid yields, supporting sustainable chemical recycling ...

The ice-nucleating ability of quartz immersed in water and its atmospheric importance compared to K-feldspar [PDF]

open access: yes, 2019
Mineral dust particles are thought to be an important type of ice-nucleating particle (INP) in the mixedphase cloud regime around the globe. While K-rich feldspar (K-feldspar) has been identified as being a particularly important component of mineral ...

Mass Spectrometric Investigation of the Influence of Water Vapour and Oxygen on Gas‐Phase Reactions of Aluminium Acetylacetonate

open access: yesAdvanced Materials Interfaces, EarlyView.
The gas‐phase decomposition of Al(acac)3 is investigated under inert, oxygen, and water‐containing conditions. Water is found to promote selective ligand removal and suppress hydrocarbon formation, while oxygen induces faster, less selective decomposition pathways.

Using titanium-in-quartz geothermometry and geospeedometry to recover temperatures in the aureole of the ballachulish igneous complex, NW Scotland

open access: yes, 2014
'Titanium-in-Quartz' geothermometry suggests quartzites could yield reliable temperature estimates. We here apply four calibrations of the titanium-in-quartz geothermometer to contact-metamorphosed quartzites surrounding the Ballachulish Igneous Complex,
