3D‐Printed Architected Anisotropic Channels for Ultrafast Solar‐Driven Interfacial Evaporation via Localized Thermal Management and Water Layer Structuring

open access: yesAdvanced Science, EarlyView.
A 3D‐printed anisotropic channel evaporator integrates directional geometry with aligned titanium oxide, boron nitride, and chitosan networks to coordinate photon absorption, heat localization, and water transport. Phonon‐guided thermal pathways and interfacial water structuring enable ultrahigh evaporation rates and long‐term salt‐resistant solar ...

Preparation of strontium hexaferrite magnets from celestite and blue dust by mechanochemical route [PDF]

open access: yes, 2008
In the present investigation celestite (natural ore of strontium) and blue dust (iron ore fines) have been used for the preparation of strontium hexaferrite powder. The mechanical alloying process has been adopted to prepare strontium hexaferrite powder.

Mechanical alloying in a planetary ball mill : kinematic description

open access: yesLe Journal de Physique IV, 1994
Based on a kinematic modeling of the planetary ball mill, the kinematic equations giving the velocity and the acceleration of a ball in a planetary ball mill apparatus are given. The kinetic energy transferred at the collision event and the shock frequency are also calculated.

Synergistic Effects of Solid Electrolyte Mild Sintering and Lithium Surface Passivation for Enhanced Lithium Metal Cycling in All‐Solid‐State Batteries

open access: yesAdvanced Science, EarlyView.
This study proposes a synergistic strategy combining mild sintering of solid electrolyte pellets with lithium metal surface passivation, effectively suppressing dendrite growth, and enhancing interfacial stability. This approach doubles the critical current density of symmetric cells (1.1 to 2.2 mA cm−2) and extends full cells cycle life at 1 mA cm−2 ...

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

open access: yesAdvanced Science, EarlyView.
ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

Rosuvastatin calcium nanoparticles: Improving bioavailability by formulation and stabilization codesign. [PDF]

open access: yesPLoS ONE, 2018
PURPOSE:Rosuvastatin calcium (ROSCa) is a poorly soluble drug with bioavailability not exceeding 20%. Decreasing the particle size may enhance its solubility, dissolution rate and bioavailability.

Mechanism of Solid Solution‐Driven Texture Induced by Ag Doping in YBCO Superconductor

open access: yesAdvanced Science, EarlyView.
Ag‐doped YBCO with a designed concentration gradient is produced by dual‐material co‐extrusion and freeze‐drying. During annealing, Ag+ ions diffuse into Y123, substituting for Cu(1) and inducing c‐axis relaxation. This leads to the formation of [001]‐oriented YBCAO, creating a coherent interface that templates the textured growth of Y123. Consequently,
