Thermal stability of piezoelectricity in polylactide polymers and related piezoelectric minimotor application

open access: yesIET Nanodielectrics, Volume 5, Issue 3-4, Page 132-138, September-December 2022., 2022
In this investigation, we fabricated the PLLA (poly(L–lactic Acid)–based bimorph structures for piezoelectric minimotor applications. The PLLA bimorph minimotor showed the maximum load of 1.2 g and the maximum torque of 0.019 cN·m. Abstract Piezoelectric polymers have been widely used in a variety of applications, including tactile sensors, energy ...

Stochastic Quantum Mechanics in Curved Spaces: Application to Schwarzschild Black Holes

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT In this work, we start from the hypothesis that the universe lives in a Gravitational Wave Background (GWB). From this hypothesis, it follows that space–time is not locally flat because we have to take into account the fluctuations of the GWB in space–time. This implies that sufficiently small particles will feel these oscillations, preventing

Comparative Analysis of Phenotypic and Genotypic Differences Between Individuals Affected by Regressive and Non‐Regressive Autism: A Cross‐Sectional Study

open access: yesAutism Research, EarlyView.
ABSTRACT Development among autistic youth varies widely. A subgroup of children experiences regression, defined as the loss of previously acquired developmental skills. Various genetic and environmental factors have been suggested as potential contributors.

Listening to Hong Kong children's perspectives through pretend play

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) has become an increasing concern in recent years. The issue has been regularly discussed by different stakeholders. However, the rising concern regarding quality in ECEC has not seriously taken into account children's perspectives.

Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.
