Microfluidic Capillary Arrays for Pixelated Control of Multimaterial Flows

open access: yesSmall, EarlyView.
A 3D‐printed pixellated capillary array maps up to thousands of fluid inputs into arbitrary multimaterial flow cross‐sections. Automated manifold design and laminar scaling are used to amplify printing resolution orders of magnitude, generating microscale fluidic control from printed elements, enabling designed microflows for potential use in ...

Vibrational Exfoliation of 2D Materials

open access: yesSmall, EarlyView.
Vibrational energy folds, fractures and exfoliates atomically and molecularly thin materials. Combining experimentation and computational methods, this unique vibrational synthesis pathway is revealed. This process overcomes barriers of existing approaches by processing 1000 g/L dispersions without loss in yield.

Water Droplet Hammer: Piezoelectric Sensing of Ultrafast Mechanical Transients During Droplet Impact

open access: yesSmall, EarlyView.
Droplet impact on solid surfaces produces an ultrafast substrate‐coupled mechanical response that is resolved by PVDF piezoelectric sensing. An initial impulsive strain pulse is followed by interfacial oscillations before rebound. Weber‐number and timescale analyses reveal how droplet inertia, surface wettability, impact regime, and liquid viscosity ...

Experimental Study on Laminar Burning Velocity and Flame Instability of Liquefied Petroleum Gas/Dimethyl Ether Blended Gas: Effects of Equivalence Ratio and Blended Ratio

open access: yesSafety Science and Technology, EarlyView.
This study reveals the regulatory effect of LPG addition on laminar burning velocity of DME/air mixtures, and elucidates the governing mechanisms of flame instability under varying initial conditions. ABSTRACT Liquefied petroleum gas/dimethyl ether (LPG/DME) blended gas is a promising clean alternative fuel, characterized by high efficiency and clean ...

Linguistic Variation across Instructional Segments in International Teaching Assistants' Discourse: A Corpus‐Based Analysis

open access: yesTESOL Quarterly, EarlyView.
Abstract This study investigates internal linguistic variation in the instructional discourse of international teaching assistants (ITAs) by segmenting their mini‐lecture performances into four discourse types: introduction, lecture, conclusion, and audience interaction.
