In order to understand the electro-mechanical behavior of piezoelectric electro active paper (EAPap), the converse and direct piezoelectric characterization of cellulose EAPap was studied and compared. A delay between the electrical field and the induced strain of EAPap was observed due to the inner nano-voids or the localized amorphous regions in layer-by-layered structure to capture or hold the electrical charges and remnant ions. The linear relation between electric field and induced strain is also observed. The electro-mechanical performance of EAPap is discussed in detail in this paper.

The adoption of carbon capture, utilization, and storage (CCUS) technology is increasingly prevalent, driven by the global initiative to conserve energy and reduce emissions. Nevertheless, CCUS has the potential to induce corrosion in equipment, particularly in high-pressure environments containing carbon dioxide (CO). Therefore, anti-corrosion protection is necessary for the metal utilized for CO production and storage equipment.

Alien species can influence populations of native species through individual-level effects such as predation, competition, and poisoning. For alien species that possess strong defensive chemicals, poisoning is one of the most powerful mechanisms of individual-level effects on native biota. Although toxic alien species could potentially negatively affect survival (lethal effects) or life history traits (sub-lethal effects) of native predators via poisoning, previous studies have mainly focused on acute lethal effects.

Dielectric-based energy storage capacitors characterized with fast charging and discharging speed and reliability play a vital role in cutting-edge electrical and electronic equipment. In pursuit of capacitor miniaturization and integration, dielectrics must offer high energy density and efficiency. Antiferroelectrics with antiparallel dipole configurations have been of significant interest for high-performance energy storage due to their negligible remanent polarization and high maximum polarization in the field-induced ferroelectric state.

Fasciola-induced fascioliasis is a zoonotic disease with significant health and economic impacts on humans and livestock. Freshwater Lymnaea snails serve as intermediate hosts, contributing to the increasing prevalence of fascioliasis in cattle in coastal areas. The salinity tolerance of Lymnaea snails was investigated along with their distribution and Fasciola infection rates in both snails and grazing cattle in Ben Tre, Tra Vinh, and Soc Trang provinces in Mekong Delta, Vietnam, where seawater reversely enters into the paddy field during the dry season.

The obstetrics and mental health care fields have significant crossover. Women with unintended, undesired, or medically complex pregnancies are at greater risk of adverse mental health outcomes, which have the capacity to create long-lasting and intergenerational ripple effects within their larger family unit. Given the frequency with which women seek pregnancy terminations, the numerous factors that influence care accessibility, and the serious repercussions that stem from insufficient use of evidence-based care surrounding pregnancy termination, women are at risk of experiencing a range of mental health outcomes based on their experiences around pregnancy termination.
