Multifunction Force Sensor with Hollow Structure

2020 IEEE International Conference on Flexible and Printable Sensors and Systems (FLEPS), 2020
In this study, the material of the dielectric layer was changed to reduce the structural rigidity of a capacitive tactile sensor, achieving the result of increasing the detection sensitivity without affecting the spatial resolution. Simulation and experimental results showed that the sensitivity of the sensor can be greatly improved by changing the ...

Mesoporous Organosilica Hollow Microspheres with Hierarchical Structures on the Shell

Journal of Nanoscience and Nanotechnology, 2013
Hierarchical mesoporous organosilicas with hollow structures have been readily synthesized from one template approach by using Pluronic P123 as a surfactant and 1,2-bis(trimethoxysilyl)ethane as precursor in mild HAc-NaAc (pH = 4.4) buffer solution. The obtained hierarchical mesoporous organosilica hollow spheres with raspberry-like morphology have at ...

Structural Characterisation of Diffusion-Bonded Hollow Sphere Structures

Defect and Diffusion Forum, 2008
This paper investigates the structural properties of sintered hollow sphere struc- tures. First of all, the packing density is analysed using three different methods: namely, liquid infiltration, Archimedes' principle, and image processing of micrographs. In addition, the pore fraction in the metallic sphere shells is characterised based on micrographs

Plastic Behavior of Hollow Structural Sections

Journal of the Structural Division, 1972
A series of tests on beams of hollow structural sections was conducted to determine their adequacy in plastic design. A minimum plastic rotation requirement of law times the elastic limit rotation prior to unloading below the fully plastic moment was used to separate sections into categories of plastic and allowable stress design. Local buckling caused

Laser drilling of hollow sphere structures

Materialwissenschaft und Werkstofftechnik, 2014
A special composite and cellular material – the metallic hollow sphere structure (MHSS) – represents an advanced material. The core element of the structure is a hollow sphere with a wall out of porous steel. This shell allows a high geometric reproducibility. It is an interesting base material for lightweight design.

Hybrid hollow structures for hydrogen storage

International Journal of Hydrogen Energy, 2020
Abstract Nanohybrids have shown considerable promise for hydrogen storage due to their enhanced capacity and fast kinetics. Hollow nanostructures have attracted considerable attention in diverse contexts and recently have been envisaged as nanocontainers for hydrogen storage.

Structure borne sound in metallic hollow sphere structures

Materialwissenschaft und Werkstofftechnik, 2011
AbstractMetallic hollow sphere structures (MHSS) form a relatively new group of advanced composite materials characterised by high geometry reproduction leading to stable mechanical and physical properties. The MHSS combine the well‐known advantages of cellular metals in terms of their high ability for energy adsorption, good damping behaviour ...

Modelling of hollow structural section trusses

Canadian Journal of Civil Engineering, 1992
It has been recently advocated that a practical static design of hollow structural section (HSS) Warren and Pratt trusses, having either gapped or overlapped connections, can be performed on the basis of a force distribution obtained from an elastic analysis of the truss with either all the members pin-jointed or the web members pin-jointed to ...

Local Buckling of Hollow Structural Sections

Journal of Structural Engineering, 1985
An analytical technique for predicting the local buckling behavior of thin-walled sections was used to predict elastic and inelastic local buckling capacities of axially loaded hollow structural sections. The technique, similar to a finite strip method, is based on the principle of virtual work and uses a Rayleigh-Ritz solution procedure.

Problems in the Identification of Application Areas of Hollow Spheres and Hollow Sphere Structures

2009
Victor Hugo (1802-1865) is attributed the verifiably false quotation that nothing is as powerful as an idea, whose time has come. Be that as it may, this quotation is at first a causality statement, which combines the presence of a certain idea in connection with specific basic conditions (time) as almost inevitable for a certain successful development.
