The Coupling of Ferroelectric Polarization and Oxygen Vacancy Migration Enables Electrically Controlled Thermal Memories

Advanced Materials, EarlyView.
Ferroelectric Hf0.5Zr0.5O2 epitaxial thin films exhibit a non‐volatile, electrically controlled thermal conductivity enabled by the coupling between oxygen vacancy migration, acting as phonon scatterers, and ferroelectric polarization, acting as ion migration valve.

Poly(Hydroxybutyrate‐Co‐Hydroxyvalerate)/Thermoplastic Starch Blends for Application in Biodegradable Mulch Films

Polymer Engineering &Science, EarlyView.
Poly(hydroxybutyrate‐co‐hydroxyvalerate)/thermoplastic starch blends, produced by melt processing, showed improvements in mechanical properties and water vapor transmission barrier performance, which can help control excessive water evaporation from the soil, thus contributing to pH and moisture regulation.

Granules morphology and rheological behavior of green banana (Musa cavendishii) and corn (Zea mays) starch gels Morfologia dos grânulos e comportamento reológico dos géis de amido de banana verde (Musa cavendishii) e milho (Zea mays)

Ciência e Agrotecnologia, 2007
In this work, it was used starch obtained from green banana (Musa cavendishii) and commercial corn (Zea mays) starch in order to compare the granule morphology and the rheological behavior of these gel-starches.

Chemically‐Linked Heterostructures of Palladium Nanosheets and 2H‐MoS2

Small, EarlyView.
The photoresponse of MoS2 devices is extended to the near‐infrared region (up to 1700 nm) through chemical connection to Pd nanosheets (PdNS). A maleimide is used for covalent connection to MoS2, and a phenyl bromide moiety for linkage to the PdNS. In the absence of the chemical linker, van der Waals heterostructures show poorer enhancement of the ...

Acúmulo de ácido oxálico e cristais de cálcio em ectomicorrizas de eucalipto.: II- formação de cristais de oxalato de cálcio induzida por fungos ectomicorrízicos em raízes laterais finas Accumulation of oxalic acid and calcium crystals in ectomycorrhizas of eucalypt.: II- calcium oxalate crystal formation induced by ectomicorrhizal fungi in fine lateral roots

Revista Brasileira de Ciência do Solo, 2009
O eucalipto é eficiente na aquisição de Ca do solo, mas pouco se sabe sobre a participação das ectomicorrizas e dos ácidos orgânicos nesse processo em campo. O acúmulo de cristais de Ca (CaOx) foi avaliado em, aproximadamente, 2.100 raízes laterais finas

Changes in the anatomical structure of eucalyptus grandis wood chips in three conditions wood chip refining for production of MDF panel [PDF]

, 2008
A utilização da madeira de eucalipto na confecção de painéis MDF é recente, tornando-se necessário entender as modificações em sua estrutura anatômica durante as etapas do processo industrial, notadamente no desfibramento dos cavacos.

Suspendable and Scalable Ultrasound‐Actuated ZnO‐Nanosheet‐Based Piezoelectric Microdevices for Wireless Electrical Stimulation of Cells

Small, EarlyView.
Silicon microtechnology enables the scalable fabrication of cytocompatible microdevices for wireless electrical stimulation. Microdevices smaller than a cell allow accurate interaction with single cells. By integrating piezoelectric nanostructures that can be actuated by ultrasound within the biomedical range, remote electrical cell stimulation is ...
