Laboratory studies of silicon vapor deposition, phase A [PDF]

open access: yes
A system is described capable of carrying out silicon vapor deposition experiments in the low 10 to the minus 10th power torr vacuum range. The system was assembled and tested for use in a program aimed at exploration of vacuum heteroepitaxy of silicon ...

Electrothermally Controlled 3D‐Printed Shape Memory Polymers for Near‐Ambient Temperature Soft Robotic Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
In this article, we develop bespoke resins for stereolithography 3D‐printing of soft‐robotic grippers that are controlled remotely by electrothermal stimulus near ambient temperatures. Turning on the electrical control, each finger can be actuated separately.

Worm‐Inspired Soft Robots With Modular Outfit‐Changing for Intelligent Multienvironment Adaptation

open access: yesAdvanced Intelligent Systems, EarlyView.
This study proposes a worm‐inspired soft robot capable of locomotion across multiple environments through a modular “outfit‐changing” strategy. The robot integrates pneumatically actuated peristaltic segments with interchangeable external modules, enabling efficient motion on ground surfaces, within pipelines, through granular media, and underwater ...

Scalable High‐Force Zipping Electrostatic Actuators

open access: yesAdvanced Intelligent Systems, EarlyView.
An electrostatic actuator architecture is presented that combines high energy density with forces and strokes suited for wearable soft robotics. By folding patterned thin films into a scalable honeycomb of zipping units, performance becomes tunable through series–parallel design, achieving over 40 N and 28 J/kg.

Resource allocation and growth strategies in a multi‐plant firm: Kanegafuchi Spinners in the early 20th century

open access: yesStrategic Management Journal, EarlyView., 2023
Abstract Research Summary Using detailed plant‐ and individual‐level data from a major Japanese cotton spinning company in the early 20th century, we examine the within‐firm allocation of skilled human capital in conjunction with investment in physical capital, accompanying the firm's evolving strategic priorities.

Visualization of toxin gene expression patterns in ribbon worm tissue sections by spatial transcriptomics

open access: yes, 2021
Ribbon worms (Nemertea) are active predators that use a proboscis to inject toxins into prey and defend themselves with toxic epidermal mucus. Nemerteans do not have distinct multi-cellular venom glands, instead toxins are secreted by cells lining the body wall and proboscis epithelia.

Structural problems without structural solutions? Youth leaders' perceptions of their community

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract As young people explore and reflect on the conditions of their neighborhoods and communities, they can forge a critical consciousness—merging their perspectives and analysis to direct both individual and collective actions. Photovoice is a methodological tool that allows participants to document their perspectives and analysis and discuss with

A Dithio Vinylthio C2 Synthon Enabling Crystalline and Luminescent Sulfur‐Decorated Polymers

open access: yesAngewandte Chemie International Edition, EarlyView.
Transforming CaC2 into a modular C2 building block enables the synthesis of α,ω‐bis(vinylthio) monomer and its conversion into crystalline, sequence‐defined sulfur‐decorated polymers. Their dense thioether clustering induces nonconventional luminescence and provides structure–function control in a more‐sustainable polymer platform.
