AI Article Synopsis
- Polymer freestanding membranes with permanent bipolar patterns are created using a process called "pyroelectrification," which involves heating periodically poled lithium niobate (PPLN) crystals.
- This thermal stimulation triggers a combination of effects, including the pyroelectric effect and the glass transition of the polymer, allowing for periodic electric poling of the material.
- The membranes have shown reliable performance in both dry and wet environments, making them suitable for applications like cell patterning.
Article Abstract
Polymer freestanding membranes with permanent bipolar patterns are fabricated by "pyroelectrification". The thermal stimulation of periodically poled lithium niobate (PPLN) crystals simultaneously generates the pyroelectric effect, the glass transition of the polymer, and therefore the periodic electric poling of the polymer. The reliability of these membranes is demonstrated for applications under both dry and wet conditions, including cell patterning.

In the tissue regeneration field, stem cell transplantation represents a promising therapeutic strategy. To favor their implantation, proliferation and differentiation need to be controlled. Several studies have demonstrated that stem cell fate can be controlled by applying continuous electric field stimulation.

Background: Individuals, who suffer from severe mental illnesses (SMI), such as bipolar disorder (BD), schizophrenia (SCZ), and major depressive disorder (MDD), are more likely to engage in risky sexual behavior. A severe mental illness can lead to a decrease in impulse control, a reduction in cognitive function and memory, and a psychosocial impairment that increases risky sexual behavior. Risky sexual behavior (RSB) can lead to health problems such as sexually transmitted infections, including HIV/AIDS, early pregnancy, and unplanned pregnancies.

Detecting transitions in bipolar disorder (BD) is essential for implementing early interventions. Our aim was to identify the earliest indicator(s) of the onset of a hypomanic episode in BD. We hypothesized that objective changes in sleep would be the earliest indicator of a new hypomanic or manic episode.

Bipolar disorder (BD) is a significant neuropsychiatric condition characterized by marked psychological mood disturbances. Despite extensive research on the symptomatology of BD, the mechanisms underlying its development and presentation remain unknown. Consequently, potential treatments are limited, and existing medications often cause significant side effects, leading to treatment discontinuation.
