Recyclable Printed Liquid Metal Composite for Underwater Stretchable Electronics

open access: yesSmall Science, Volume 5, Issue 5, May 2025.
This work presents a multifunctional liquid metal (LM) microdroplet‐based composite with a custom‐designed block copolymer as the matrix, optimized for printing. The composite exhibits high conductivity, stretchability, durability in dry and aqueous environments, and recyclability of LM using green solvents. These properties highlight its potential for

Altitude performance of a low-noise-technology fan in a turbofan engine with and without a sound suppressing nacelle [PDF]

open access: yes
Test variables were inlet Reynolds number index (0.2 to 0.5), flight Mach number (0.2 to 0.8), and flow distortion (tip radial and combined circumferential - tip radial patterns). Results are limited to fan bypass and overall engine performance.

Nanoarchitecturing of Bimetallic Metal‒Organic Frameworks for Emerging Applications in Quartz Crystal Microbalance Gas Sensors

open access: yesSmall Methods, EarlyView.
This review summarizes recent progress in the design and nanoarchitectural control of bimetallic metal–organic frameworks (MOFs) and their applications in quartz crystal microbalance (QCM) sensors for the detection of various gases. It also discusses the underlying sensing mechanisms of bimetallic MOFs and concludes with challenges and future ...

The NASA Langley Laminar-Flow-Control Experiment on a Swept Supercritical Airfoil: Basic Results for Slotted Configuration [PDF]

open access: yes
The effects of Mach number and Reynolds number on the experimental surface pressure distributions and transition patterns for a large chord, swept supercritical airfoil incorporating an active Laminar Flow Control suction system with spanwise slots are ...

Cellular concrete: A viable low‐carbon alternative for developing countries in seismic regions?

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the potential of cellular concrete as an environmentally friendly alternative for shear walls based structural systems in seismic‐prone areas. The construction industry significantly contributes to global energy consumption and carbon emissions, mainly through the use of conventional materials like concrete and steel ...

The Trajectory of an Agreement: Tracing Objectivated Knowledge Across a Series of Mundane Encounters

open access: yesSymbolic Interaction, EarlyView.
This article adds to the sociological study of time and temporality in everyday life by building on recent longitudinal developments within conversation analysis. It investigates members' methods to bring about change within their shared (life) world. It examines how, as part of an extended project of action, one agreement made early on is continually ...

Hunting, but not outdoor recreation, modulates behavioural tolerance to human disturbance in Alpine marmots Marmota marmota

open access: yesWildlife Biology, EarlyView.
Humans are often perceived as predators by free‐living animals, and thus, even non‐consumptive human activities such as outdoor recreation may trigger behavioural and physiological responses, often with negative consequences on individual fitness and population persistence.

Periodic vortex shedding in the supersonic wake of a planar plate [PDF]

open access: yes
Vortex sheets in the wake have been mainly studied in incompressible flows and in the transonic region. Heinemann et al. (1976) have shown that for the subsonic region the Strouhal number is nearly independent of the Mach number.
