Highly Efficient 3D‐Printed PVDF‐Based Triboelectric Nanogenerators Featuring Polymorphic Perovskite Nanofillers

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates the use of a low‐cost 3D printing technique to prepare a large‐area PVDF‐FAPbI3 composite dielectric film for flexible TENG application. The δ→α phase transformation of the FAPbI3 nanofillers has significantly improved the β‐phase content, morphology, and dielectric properties of the PVDF film.

Experimental and Theoretical Confirmation of Covalent Bonding in α‐Pu

open access: yesAdvanced Functional Materials, EarlyView.
From a combination of Reverse Monte Carlo dynamic rigid body fitting to the pair distribution functional and novel density functional approaches, the existence of covalent bonding is confirmed in α‐plutonium alongside other bonding types (i.e. mixed bonding schemes).

Vanadium Doped Magnetic MoS2 Monolayers of Improved Electrical Conductivity as Spin‐Orbit Torque Layer

open access: yesAdvanced Functional Materials, EarlyView.
Electrically conductive and room temperature magnetic atomically thin (≈0.8 nm) vanadium doped MoS2 (V‐MoS2) is demonstrated for its spintronic applications. Here, the spin transport at the interface of permalloy (Py) and high spin‐orbit coupling V‐MoS2 magnetic monolayers is shown.

LATE PRE-HISPANIC AND EARLY COLONIAL SILVER PRODUCTION IN THE QUEBRADA DE TARAPACÁ, NORTHERN CHILE LA PRODUCCIÓN DE PLATA EN LOS PERÍODOS PREHISPÁNICO TARDÍO Y COLONIAL TEMPRANO EN LA QUEBRADA DE TARAPACÁ, NORTE DE CHILE

open access: yesBoletín del Museo Chileno de Arte Precolombino, 2010
Drawing on a survey of the Quebrada de Tarapacá in northern Chile and excavations at the Inka and Colonial administrative site of Tarapacá Viejo, we present archaeological evidence of small-scale purification of silver using lead.

Substrate Engineering for Durable Omniphobic Liquid‐Like Surfaces

open access: yesAdvanced Functional Materials, EarlyView.
The significant yet less investigated role of substrates in determining the liquid‐repellency and mechanical durability of liquid‐like surfaces (LLSs) is explored. Thick and crack‐free sol–gel silica intermediary layers are developed that can smoothen substrate asperity roughness even at the micron scale, enabling omniphobic polydimethylsiloxane‐based ...

Process safety in metallurgical producion

open access: yesMetalurgija, 2020
As a consequence of technological accidents regular conditions of metallurgical processes can change into operational discontinuity. For that reason the main aim of the paper is to present a concept of the risk based process safety assurance.
