Do landfills affect the environmental quality of nearby streams?

Biotemas, 2017
When inappropriately disposed, solid waste may contaminate the soil, water and air, leading to severe negative impacts on biodiversity. The Brazilian National Policy for Solid Waste (PNRS) requires municipalities to ensure the environmental quality of ...

Relaxor ferroelectric behavior: An approach considering both the dipolar and electrical conductivity contributions

Journal of Advanced Dielectrics, 2021
The relaxor behavior of PLZT ferroelectric ceramics has been analyzed in a wide frequency and temperature ranges, below and above the temperature for the formation of the so-called polar nano-regions (PNRs).

Relaxor Ferroelectricity Enables Enhanced Thermoelectric Performance in In₂Se₃-Alloyed GeTe. [PDF]

Adv Sci (Weinh)
A non‐equimolar In3+/Se2− alloying strategy creates Ge vacancies in GeTe, inducing relaxor ferroelectricity that broadens the low thermal conductivity window. Simultaneously, cubic phase stabilization broadens optimal electrical transport, achieving an average zT > 1.0 over 330–625 K.

Nanostructured Conductive Polypyrrole for Antibacterial Components in Flexible Wearable Devices

Research, 2023
The power generated by flexible wearable devices (FWDs) is normally insufficient to eradicate bacteria, and many conventional antibacterial strategies are also not suitable for flexible and wearable applications because of the strict mechanical and ...

Polymorphic Superparaelectric Engineering Boosting Energy Storage Capacity in BaTiO3‐Based Ceramics

Advanced Science, EarlyView.
Herein, Ca2+ incorporation promotes the coexistence of CaTiO3‐/BaTiO3‐derived paraferroelectric states, stabilizing cubic‐orthorhombic‐tetragonal polymorphic superparaelectric phases. This minimizes polarization energy barriers, facilitating full polarization saturation without compromising efficiency.

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Emergence of Unconventional Magnetic Order in Strain‐Engineered RuO2/TiO2 Superlattices

Advanced Science, EarlyView.
Epitaxial strain activates unconventional magnetism in rutile RuO2, absent in bulk or relaxed RuO2. Polarized neutron reflectometry with atomic‐layer resolution directly reveals finite magnetization confined to RuO2 layers in fully strained RuO2/TiO2 superlattices on TiO2 (110).
