Scattering theory and cancellation of gravity-flexural waves of floating plates

, 2019
We combine theories of scattering for linearized water waves and flexural waves in thin plates to characterize and achieve control of water wave scattering using floating plates. This requires manipulating a sixth-order partial differential equation with

Hybrid Magnetoactive Soft Elastomers: Material Development Toward Application in Diaphragm Pumps

Advanced Materials Technologies, EarlyView.
Hybrid magnetoactive soft elastomeric membranes are developed by combining two different types of magnetic particles. The membranes exhibit distinct mechanical, magnetic and thermal properties owing to the unique characteristics of the two magnetic particles.

Direct Formation of Structural Components Using a Martian Soil Simulant. [PDF]

, 2017
Martian habitats are ideally constructed using only locally available soils; extant attempts to process structural materials on Mars, however, generally require additives or calcination.

The Improvement of Modified Rice Straw Fiber/Polyvinyl Alcohol Thermoplastic Polymer Composite Using Cold Plasma Technology

Indonesian Journal of Chemistry
The use of natural rice straw as a filler for composite materials has not been optimally utilized; only around 7–16% of the grain is used in the industry. Various developments have been carried out, including its use as a filler or reinforcement for wood

Flexural Horns [PDF]

The Journal of the Acoustical Society of America, 1964
Tapered solid elastic rods have previously been used as horns or velocity transformers for longitudinal and torsional vibrations. Such structures may also be employed as velocity transformers when vibrating in flexure. An approximate 1-dimensional wave equation describing the vibration of such “flexural horns” has been derived from thin-bar theory. The

Micropillar‐Engineered Hybrid Adhesive Patch for Surface‐Conformable and Directional Adhesion

Advanced Materials Technologies, EarlyView.
This work presents a surface‐conformable hybrid adhesive integrating height‐optimized hexagonal micropillars with open‐rectangular cuts. The micropillars enhance rough‐surface contact and microscale crack arrest, while the cuts guide and reverse interfacial cracks for strong and directional adhesion. The multiscale architecture achieves robust pull‐off
