Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Lúcia Nagib: Realist Cinema as World Cinema Non-cinema, Intermedial Passages, Total Cinema.

open access: yes, 2021
Der Realismus im Film war seit den 1920er- bis in die 1960er-Jahre ein beliebtes Thema von Filmtheoretiker*innen und -kritiker*innen, vom sowjetischen Filmemacher Dziga Vertov bis hin zum deutschen Filmhistoriker Siegfried Kracauer, aber auch etwa für die einflussreiche Filmzeitschrift Cahiers du Cinema und ihren Mitbegründer André Bazin.

Engineered Mycelial Scaffolds With Tunable Ultraviolet Protection, Wettability, Thermal Stability, and Spatial Mechanics

open access: yesAdvanced Engineering Materials, EarlyView.
Fungal mycelia grown into biodegradable scaffolds and infused with titania nanoparticles show enhanced ultraviolet shielding, thermal protection, and surface nonwettability. Properties were tuned by drying methods, revealing structure–function relationships.

A Technician's Dream? The Critical Reception of 3-D Films in Britain [PDF]

open access: yes, 2012
Recent debates about the role of 3-D within cinema (and other media) have contained the traces of a largely anti-stereoscopic agenda that can be traced back to critical responses to 3-D in the 1950s.

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Investigation of Oxygen‐Free Wetting Behavior of Aluminum on Copper via Molecular Dynamics Simulations and Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.

Resistance Rapid Heating of Aluminum Coatings in an Extreme High Vacuum–Adequate Atmosphere for Hot Stamping

open access: yesAdvanced Engineering Materials, EarlyView.
The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.

Kino für Historiker

open access: yesÖsterreichische Zeitschrift für Geschichtswissenschaften, 1997
The article sets out with a methodological founding for a semio-historical analysis of the film La Marseillaise by Jean Renoir. This argument for a combination of the approaches of film-history and film-analysis favours a certain type of research, which ...
