Triboelectric Capacitance Supplementation in Energy Storage Composites with Functionalized Carbon Fiber Electrodes

Small, EarlyView.
Triboelectric contact electrification evaluation between structural supercapacitor layers using surface‐functionalized carbon fiber electrodes. Electrospun nanofiber separators can aid in capacitance augmentation by leveraging the contact electrification effect of dissimilar materials.

The Automated Threaded Fastening Based on On-line Identification

International Journal of Advanced Robotic Systems, 2008
The principle of the thread fastenings have been known and used for decades with the purpose of joining one component to another. Threaded fastenings are popular because they permit easy disassembly for maintenance, repair, relocation and recycling ...

In-plane stiffness of timber floors strengthened with CLT [PDF]

, 2015
Five full-scale timber floors were tested in order to analyse the in-plane behaviour of these structural systems. The main objective was an assessment of the effectiveness of in-plane strengthening using cross-laminated timber (CLT). To this end, one

Self-Drilling Versus Self-Tapping Screws: A 3D Finite Element Analysis

Craniomaxillofacial Trauma & Reconstruction, 2020
Study Design: Self-tapping and self-drilling screws are two modalities available for plate fixation. When compared to self-drilling, self-tapping screws have a few drawbacks like screw loosening, thermal osteolysis, equipment dependent, and time-consuming.

Analysis of flow rates in cracked reinforced concrete

Structural Concrete, EarlyView.
Abstract According to Eurocode 2, part 3, autogenous self‐healing of separation cracks with a width ≤0.20 mm can be considered under certain hydraulic conditions. However, practical experience shows that healing does not always reliably occur even when this crack width is maintained.

Withdrawal Capacity of a Novel Rigging Device for Prefabricated Wood I-Joist Floor Panels

Buildings
Prefabricated wood construction relies heavily on efficient material handling, yet rigging system design for floor panels remains understudied. This study introduces a novel rigging device that attaches to prefabricated wood I-joist floor panels using ...

Variability of the pullout strength of cancellous bone screws with cement augmentation [PDF]

, 2015
Background Orthopaedic surgeons often face clinical situations where improved screw holding power in cancellous bone is needed. Injectable calcium phosphate cements are one option to enhance fixation. Methods Paired screw pullout tests were undertaken in

The Interactional Pathways of Mass Killings: Toward a Novel Understanding of Rampage School Shootings

Symbolic Interaction, EarlyView.
Rampage school shootings, where students go to their own school to randomly kill classmates, teachers, friends, and strangers, are among the most drastic types of human behavior. While research increasingly points to interaction dynamics as being key for the emergence of crime and violence, scholars have not yet systematically studied interaction ...

Experimental study on the effect of the riveting process on the bending resistance of beams composed of galvanized Q235 steel

High Temperature Materials and Processes
In this article, a hollow flange beam (ARHFB) composed of self-piercing rivet (SPR) and galvanized steel sheet was proposed, and the process parameters and mechanical properties of SPR connection technology for Q235 galvanized steel sheet were studied ...
