Multiple‐Repeated Plasma Surface Treatments for Significantly Improving Bonding Performance of Metal‐Carbon‐Fiber‐Reinforced Thermoplastic Polymer Dissimilar Adhesive Joints

open access: yesAdvanced Engineering Materials, EarlyView.
Multiple plasma surface treatments improved the Mode I fracture energy of metal‐carbon‐fiber‐reinforced thermoplastic polymer (CFRTP) joints by ≈240% compared to single treatments and nearly 2000% over untreated joints. This significant enhancement, achieved without modifying CFRTP surface roughness, is attributed to improved chemical bonding at the ...

On the Formulation of Basal Debris Drag for the Case of Sparse Debris [PDF]

open access: yesJournal of Glaciology, 1988
AbstractTwo models are presented for the formulation of abrasion and basal drag due to rock–rock friction (debris drag) for the case of sparse debris entrained in the basal layers of a temperate glacier resting on a bedrock bed. The first model is formulated in terms of average basal melting rate, va, and the concentration, C, of basal debris fragments

A Study on Thermal Expansion and Thermomechanical Behavior of Composite Metal Foams

open access: yesAdvanced Engineering Materials, EarlyView.
The coefficient of thermal expansion of steel–steel composite metal foam (S‐S CMF) is shown to be lower than that of bulk stainless steel while its performance under compression demonstrate excellent mechanical stability and strength at all temperatures with gradualsoftening from 400 to 600 °C.

Remnants of the city

open access: yesMateria Arquitectura, 2017
Contrary to what has historically happened with earthquakes that have repeatedly destroyed several cities in Chile, the 2010 earthquake was followed by an unprecedented and fruitful reflection that, from various disciplines, has tried to understand ...

A Concept For Elimination Of Small Orbital Debris [PDF]

open access: yesarXiv, 2011
A concept for forced reentry of small orbital debris with characteristic dimension ~ 10 cm from the highly populated sun synchronous orbit by injecting micron scale dust grains to artificially enhance drag is discussed. The drag enhancement is most effective when dust grains counter rotate with respect to the debris resulting in hypervelocity dust ...

Low‐Velocity Penetration Impact Behavior of Triply Periodic Minimal Surface Strut‐Based Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS)‐based lattices are gaining attention for their multifunctional properties in applications as aeronautics and automotive, which involve low‐velocity impact loading. This work evaluates the low‐velocity penetration impact behavior of five distinct TPMS architectures.

Amplification‐Free, Sequencing‐Free, Detection of Viral RNAs with Variant Specification by Discrete Nanocounting

open access: yesAdvanced Functional Materials, EarlyView.
Integrating selective RNA shortcut, targeted gene isolation, and micro‐arrayed nanoimaging, the NanoPick‐array platform excels in detecting severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) at just 60 copies µL−1 and accurately differentiating variants at the single‐nucleotide level. It ensures 100% accuracy for samples with cycle threshold (
