MXene Wrapped Magnetic Mesocrystals for Durable Redox Catalytic Cancer Therapy and Responsive MRI

open access: yesAdvanced Functional Materials, EarlyView.
Conformal wrapping of ultrathin Ti3C2Tx MXene nanosheets on Fe3O4 mesocrystals creates topology‐stabilized Schottky junctions that direct photoinduced electron transfer under NIR irradiation. The unique architecture sustains Fenton catalysis, promotes continuous hydroxyl radical production, and provides photo‐responsive MRI contrast.

Toward Fast Proton Shuttling in Acidic Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
This review establishes proton transfer dynamics as a descriptor governing acidic OER activity, moving beyond the kinetic constraints derived from the proton coupled electron transfer. We discuss how deprotonation governs classical mechanisms, including adsorbate evolution mechanism (AEM), lattice oxygen mechanism (LOM) and oxide path mechanism (OPM ...

Application of Ibuprofen Sodium Dihydrate for Thermochemical Energy Storage

open access: yesAdvanced Functional Materials, EarlyView.
Ibuprofen sodium dihydrate is introduced as a durable organic salt hydrate for low‐temperature thermochemical energy storage, operating within 60°C–110°C with high energy density. At the material level, it delivers ∼99.9% cycling efficiency over 150 cycles without deliquescence, enabled by a dual energy‐storage mechanism coupling dehydration and phase ...

Absorption spectra of bone

Calcified Tissue Research, 1977
Absorption spectra of human bone and its two major constituents (collagen and apatite) were obtained in the wavelength region extending from 2000 to 12,000 A. In the last two cases a minimum transmission (maximum absorption) was uniformly observed in the ultraviolet region.

Absorption Spectra of RbCl:Tl

Physica Status Solidi (a), 1979
Kubelka's method is used to record absorption spectra of RbCl + TlCl mixed phosphor in the region 210 to 300 nm for various thallium concentrations at 300 K. The absorption spectra so recorded are presented and discussed. A single absorption band at very low thallium content (0.01 mol%) is obtained at 248.5 nm.

Absorption Spectra of the Sodium Peruranates

Nature, 1950
IT was shown by Scott1 that the presence of bicarbonate in solutions of sodium peruranate, formed by the addition of excess hydrogen peroxide to sodium uranyl tricarbonate solution, caused errors in the absorptiometric determination of uranium. Smales and Furby2 found the optical density to be dependent on both the pH and the carbonate content of the ...
