Advanced Materials, EarlyView.Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Acoustic Simulation of Underwater Sounds [PDF]
The Journal of the Acoustical Society of America, 1964 Training of sonar personnel in the recognition of underwater sounds can be greatly facilitated by electronic simulation of target-radiated noises. For simulation purposes, radiated noise from a vessel is composed of a shaped broad-band noise-spectra and line-spectra components.

Underwater Acoustic simulations with a time variable acoustic propagation model [PDF]
, 2010 The Time Variable Acoustic Propagation Model (TV-APM) was developed to simulate underwater acoustic propagation in time-variable environments. Such environment variability induces a strong Doppler channel spread, which is an important factor to test and ...

Validating acoustical simulations in the Bell Labs Box
IEEE Computer Graphics and Applications, 2002 Computer simulated sound propagation through 3D environments is important in many applications, including computer-aided de-sign, training, and virtual reality. In many cases, the accuracy of the acoustical simulation is critical to the success of the application.

Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics
Advanced Materials, EarlyView.Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...

Broadband reflected wavefronts manipulation using structured phase gradient metasurfaces
AIP Advances, 2016 Acoustic metasurface (AMS) is a good candidate to manipulate acoustic waves due to special acoustic performs that cannot be realized by traditional materials. In this paper, we design the AMS by using circular-holed cubic arrays.
