A Digital Hydraulic Valve, Actuated Using a Piezoelectric Linear Motor
, 2011 Proportional control in hydraulics is widely utilized. The most widely used current types of proportional valves utilize solenoid technology. While this technology has been around for decades and has been proven an effective means of control, there is ...

Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum
Advanced Materials, EarlyView.Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...

Temperature dependence bending rigidity of 2D membranes: Graphene as an example
AIP Advances, 2018 Bending rigidity plays an important role in graphene from mechanical behavior to magnetic and electrical properties. However, it is still in a theoretical debate whether the bending rigidity of graphene increase or decrease with increasing temperature ...

Thick-film Piezoceramic Microgenerators [PDF]
, 2008 Piezoelectric materials have many desirable characteristics for use in vibration energy harvesting applications. They can produce relatively high output voltages (from a few to several tens of volts) for modest levels of vibration.

Advanced Materials, EarlyView.This project developed a smart bandage‐like patch (a microneedle array) for repairing diabetic bone damage. It intelligently senses signals from infection and inflammation, then releases its medicines in a specific, timed sequence: first an antibacterial agent, then an anti‐inflammatory agent, and finally growth factors.

Advanced Materials Interfaces, EarlyView.Schematic illustration of a sustainable nanofabrication process: chitosan derived from natural sources is used as a biodegradable thin film resist, patterned via Constant Pulse‐Assisted Force Lithography (CP‐AFL) to create tunable nanogrooves. These grooves template gold nanowire formation, enabling high‐resolution nanopatterning under ambient ...

The Development of a PiezoelectricI Fan System for the Flapping Wing Micro-Air-Vehicle Application [PDF]
, 2008 A micro air vehicle (MAV) is a semiautonomous airborne vehicle which measures less than 15 cm in any dimension. It can be used to access situations too dangerous for direct human intervention, e.g., explosive devices planted in buildings and video ...
