Ultrafine Sm-Fe-N Particles Prepared by Planetary Ball Milling

open access: yesEPJ Web of Conferences, 2013
Ultrafine magnetically hard particles are needed for the bottom­up fabrication of anisotropic exchanged­coupled permanent magnets. In this study we have chosen Sm2Fe17Nx because of its high anisotropy field and large saturation magnetization.

Modular Generation of Alkyl Selenyl Radicals for the Synthesis of Alkyl Selenides via a Mechanochemical Approach

open access: yesAdvanced Science, EarlyView.
We present a mechanochemical, radical‐mediated hydroselenation of alkenes under ambient conditions. This method modularly generates alkyl selenyl radicals from elemental selenium and alkyl (pseudo)halides, utilizing PhSiH3 and H2O as hydrogen atom donors, with the water likely originating from the air and/or trace water present in the reagents ...

Nitrogen‐doped graphene catalysts: High energy wet ball milling synthesis and characterizations of functional groups and particle size variation with time and speed

open access: yes, 2017
Nitrogen‐doped graphene (N‐G) catalyst emerges as one of the promising non‐platinum group metal (non‐PGM) catalysts with the advantages of low cost, high oxygen reduction reaction (ORR) activity, stability, and selectivity to replace expensive PGM ...

In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque

open access: yesAdvanced Science, EarlyView.
In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...

Wet chemistry-synthesized Fe/mixed ferrite soft magnetic composites for high-frequency power conversion

open access: yesAIP Advances
State-of-the-art soft magnetic (SM) alloy systems such as electrical steels and permalloys exhibit large eddy current losses at high-frequency (kHz range and above), limiting their application in fast switching devices. Eddy current losses can be reduced

Exfoliation of graphene sheets via high energy wet milling of graphite in 2-ethylhexanol and kerosene

open access: yesJournal of Advanced Research, 2017
Graphene sheets have been exfoliated from bulk graphite using high energy wet milling in two different solvents that were 2-ethylhexanol and kerosene. The milling process was performed for 60 h using a planetary ball mill.

Polyelectrolyte Mediated Interaction of Alumina in Wet Jet Milled Slurry/Ball Milled Slurry Supernatants

open access: yesJournal of the Ceramic Society of Japan, 2006
In a recent paper by Omura et al.,1) wet jet milled α-alumina slurries exhibited distinctly different stability behavior compared to ball milled ones in terms of re-flocculation efficiency, rheological properties and packing density. The distinction was attributed to the different behavior of the same NH4 + salt of poly(acrylic acid) in the two milling
