Abstract A new method is presented using electrochemically generated ferrate to degrade the technically relevant bio‐based side‐stream products, lignin and lignosulfonate. An exclusive degradation vanillic acid found, which was previously a reported by‐product. As natural resource, can be utilized substitute fossil‐based chemicals in industry reduce greenhouse gas emissions positively impact cl...

We present a novel micromachining procedure employing the noble gas halide, xenon difluoride (XeF2), to rapidly undercut a sacrificial layer comprised of low-temperature deposited amorphous germanium (α-Ge). As a proof of concept, this process is utilized to fabricate electrostatically-actuated suspended Bragg mirrors applicable to wavelength-tunable surface-normal photonic devices. Exploiting ...

BACKGROUND The practice of sacrifice has occurred in several cultures and religions throughout history and still exists today. Candomblé, a syncretical Afro-Brazilian religion, practices the sacrificial ritual called "Orô" by its adherents. The present work aims to document the use of animal species in these sacrificial practices in the cities of Caruaru (PE) and Campina Grande (PB) in Norteast...

Abstract Increasing awareness for sustainability has led to the development of smart self-healing materials, which can extend service life and improve safety without human intervention. Vascular networks are observed in biological systems, such as leaf venation blood vascular provide inspiration mechanisms engineered systems. Embedding a network host material advantage addressing varying magnit...

This paper describes a feature-based approach to automated design of multi-piece sacrificial molds. We use multi-piece sacrificial molds to create complex 3D polymer/ceramic parts. Multipiece molds refer to molds that contain more than two mold components or subassemblies. Our methodology has the following three benefits over the state-of-the-art. First, by using multi-piece molds we can create...
