Surgical resection of pediatric skull base meningiomas [PDF]

open access: yes, 2018
Purpose: Meningiomas in children are rare, especially those located at the skull base. In this study, we report our experience of meningioma surgery in the pediatric population and compare our findings of skull base (SB) versus non-skull base (NSB ...

Flexible Production of Spherical Powders of Ti‐V‐Zr‐Nb‐Mo‐Hf‐Ta‐W Refractory High‐Entropy Alloys by Plasma‐Assisted Centrifugal Atomization

open access: yesAdvanced Materials Technologies, EarlyView.
In this work, spherical powders of refractory Ti‐V‐Zr‐Nb‐Mo‐Hf‐Ta‐W high‐entropy alloys (R‐HEAs) have been fabricated in a single step by plasma‐assisted centrifugal atomization. Loss of the heaviest elements in the composition is observed only at rotational speeds higher than 13 000 rpm due to solid‐solid centrifugal separation.

Zero‐Power, Optical Toxic Gas and Vapor Sensors Utilizing Printed Nematic Liquid Crystal Patterns on Selectively Reactive Substrates

open access: yesAdvanced Sensor Research, EarlyView.
Fast response, zero‐power, text or image sensors utilizing light transmission or reflection, and no unfavorable color change judgments, are fabricated using printed nematic liquid crystals patterned on reactive alignment layers, permit ppt‐ to ppb‐level sensitivity, and were field‐tested with active firefighters.
