Vibration suppression of scaled-down towers in offshore wind power based on pendulum tuned particle damper.

PLoS ONE
This paper presents a method for suppressing vibrations in a scaled wind turbine tower subjected to wind loads. The proposed approach employs a composite damping system-the Pendulum Tuned Particle Damper (PTPD). A mathematical model of the damping system

High‐Modulus Skeleton‐Reinforced PDMS Microstamps for Precision Transfer Printing of Microscale Devices

Advanced Functional Materials, EarlyView.
Elastomeric micropillars bend under contact loading, sliding microscale devices out of alignment during transfer printing. A hybrid PDMS stamp embeds a high‐modulus skeleton within each pillar while retaining a compliant contact surface. The reinforcement confines pillar deformation, suppressing interfacial sliding and preserving array registration on ...

Wave Generation by a Finite Baffle Array in Application to Beam-Forming Analysis

Archives of Acoustics, 2013
Directional excitation of sound in an aperiodic finite baffle system is analyzed using a method developed earlier in electrostatics. The solution to the corresponding boundary value problem is obtained in the spatial-frequency domain.

Thermally Robust Room‐Temperature Interlayer Excitons in a Hybrid van der Waals Heterostructure

Advanced Functional Materials, EarlyView.
We report an optically active interlayer exciton in a hybrid van der Waals (PEA)2PbBr4/MoS2 heterostructure that remains thermally stable up to 400 K. The emission exhibits polarization anisotropy consistent with an out‐of‐plane optical transition‐dipole component and shows lifetime extension indicative of electron–hole separation.

Envelope of Collapse in Gypseous Sandy Soils using Finite Element Method and Particle Image Velocimetry

Journal of Engineering
Water level rise as well as inundation to gypseous soil medium can lead to a substantial loss of volume of the soil, with or without adding load. Macromechanical behavior of gypseous sandy soils using particle image velocimetry (PIV) is yet to be ...

Hemocompatible Glycogen‐Tissue Plasminogen Activator Complexes for Enhanced Blood Clot Dissolution

Advanced Healthcare Materials, EarlyView.
Glycogen–heparin‐cRGD nanoparticles enable targeted delivery of tissue plasminogen activator (tPA) to thrombi through activated platelet recognition. The hemocompatible hybrids minimize interactions with blood and immune cells while retaining enzymatic biodegradability.
