Experimental constraints on amphibole stability in primitive alkaline and calc-alkaline magmas [PDF]

open access: yes, 2017
Equilibrium crystallization experiments were carried out on two primitive basaltic rocks (APR16: Na2O+K2O=4.40 wt%; CM42: Na2O+K2O=2.59 wt%) with the aim to investigate the amphibole stability in the differentiation processes at deep crustal level, of

Enhanced Photocatalytic CO2 Reduction Performance by External Electric Field‐Driven Charge Separation on Interdigitated Micro‐Spacing Structure

open access: yesAdvanced Science, EarlyView.
An external electric field‐enhanced photocatalytic system is developed using interdigitated electrodes with 100 µm spacing to overcome the liquid‐phase limitations of traditional PEC. The induced high‐intensity electric field effectively drives the directional migration of charge carriers under low voltage. This strategy significantly suppresses charge

Bioinspired Engineering of Streamlined Skeletal Interoception: Neural Bioprinted Piezoelectric Scaffolds for Neuro‐Vascularized Bone Regeneration

open access: yesAdvanced Science, EarlyView.
This study develops neural bioprinted piezoelectric scaffolds which construct local “sensor‐effector” circuit, inspired by the skeletal interoception system. Upon US stimulation sensing and mechanoelectrical coupling by PLLA nanofibers, the incorporated DRG neurons effect through Ca2+ influx‐induced enhanced secretion and expression of CGRP.

Dual Band Optimization and Defect Engineering Enable Ultrahigh Thermoelectric Performance in Filled Skutterudites

open access: yesAdvanced Energy Materials, EarlyView.
A synergistic dual‐modulation strategy is employed in Yb‐filled skutterudites through concurrent indium filling and tellurium doping to optimize electronic band structure and phonon scattering. Cooperative band convergence and nanoprecipitate‐induced lattice distortions yield a high zT of 1.72 and enable an ultra‐efficient thermoelectric device with 8 ...

DETERMINATION OF PERIOD OF THE FURNACE HEAPING BY MEANS OF AMPLITUDE OF ODD HARMONICS OF THE ARC PRESSURE

open access: yesЛитьë и металлургия, 2006
The harmonic components of the arc pressure are investigated on blast steel furnace-1,2. The period of the furnace heaping by means of amplitude of odd harmonics of the arc pressure is determined.
