Influence of Surface Finish on the Tribological Performance of AlTiBN Coatings Deposited on Forming Tools

open access: yesAdvanced Engineering Materials, EarlyView.
Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

open access: yesAdvanced Engineering Materials, EarlyView.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Anti-communism is All Around Us

open access: yesPraktyka Teoretyczna, 2019
The essay discusses four theses on contemporary anti-communism: 1) anti-communism is general and international; 2) anti-communism is an operator within capitalist ideology; 3) anti-communism is a politics of fear; 4) anti-communism is a lure that ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

open access: yesAdvanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

“Apolitics”, “Anti-politics”, “Non-political Politics” and “Sub-politics” as Threats and Challenges

open access: yesSociální studia, 2016
This paper focuses on explaining “the disappearance of politics” from public space roughly a quarter century after the Velvet Revolution. From the perspective of the history of ideas it clarifies several terms, such as “apolitics”, “anti-politics”, “non ...

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

open access: yesAdvanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

"I don’t give a shit where I spit my phlegm" (Tribe 8). Rejection and Anger in Queer-Feminist Punk Rock

open access: yesTransposition, 2013
This article focuses on queer-feminist punk, also known as queercore, homocore or dykecore. It presents some examples of punk rock performers and their cultural productions (Tribe 8, Agatha, Stag Bitten and others) to argue that these bands produce ...

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor

open access: yesAdvanced Functional Materials, EarlyView.
Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling
