Two techniques enable sampling of filtered and unfiltered molten metals [PDF]

open access: yes, 1967
Filtered samples of molten metals are obtained by filtering through a plug of porous material fitted in the end of a sample tube, and unfiltered samples are obtained by using a capillary-tube extension rod with a perforated bucket.

Solution‐Shearing of Highly Smooth Ion‐Gel Thin Films: Facilitating the Deposition of Organic Semiconductors for Ion‐Gated Organic Field Effect Transistors

open access: yesAdvanced Electronic Materials, Volume 11, Issue 6, May 2025.
A straightforward method is introduced to produce ion‐gel films with very low surface roughness by employing a solution‐shearing coating process. These ion‐gel films permit the growth of crystalline thin films of various small molecule organic semiconductor molecules directly on top of the ion‐gel layer, thereby enabling “inverted” small molecule ...

Pressure‐Induced Structural and Magnetic Evolution in Layered Antiferromagnet YbMn2Sb2

open access: yesAdvanced Electronic Materials, EarlyView.
Pressure tunes the delicate balance between structure, magnetism, and electronic states in quantum materials. In YbMn2Sb2, high‐pressure X‐ray and neutron diffraction reveal a trigonal‐to‐monoclinic transition near 3.5 GPa, accompanied by unconventional magnetic ordering.

Det religiøse nulpunkt

open access: yesReligionsvidenskabeligt Tidsskrift, 2001
Taking its point of departure in Frits Staal’s theory of ritual as a pure, meaningless activity, this paper identifies and further develops a somewhat similar, but more sophisticated Andamanese theory of ritual as an activity formally situated in point ...

Light Stability of Laser‐Assisted Glass Encapsulated Perovskite Solar Cells under Different Atmospheres

open access: yesAdvanced Energy Materials, EarlyView.
This study presents a laser‐assisted glass‐frit encapsulation method for perovskite solar cells, comparing air‐, nitrogen‐, and CO2‐filled cavities. Results show that excluding oxygen and moisture significantly improves stability under illumination. The findings reveal the critical role of trapped gases in degradation, providing a pathway to durable ...

Comparative Investigation of Three Mg Doping Strategies in NMC811 Cathodes for High‐Energy Density Lithium‐Ion Batteries

open access: yesBatteries &Supercaps, EarlyView.
Magnesium (Mg) doping is explored as a stabilization strategy for high‐capacity LiNi0.8Mn0.1Co0.1O2 (NMC811) cathodes. Three doping routes are compared, revealing that solid‐state lithiation delivers the best cycling stability. Operando X‐ray diffraction and electrochemical dilatometry link reduced cation mixing and lattice stabilization to improved ...

REUSE OF GLASS FIBER WASTE IN THE CIRCULAR ECONOMY

open access: yesNonconventional Technologies Review, 2020
Due to the high B2O3 content of E-type fibres, as well as the beneficial qualities of basaltic fibres, make this waste an effective alternative use in frits and glazes without PbO (considered toxic).

Cosimo’s Genius and Ammannati’s Ingenium: The Wax Model for the Genio Mediceo

open access: yesThe Rijksmuseum Bulletin, 2020
In 2018 the Rijksmuseum acquired the wax modello for the Genio Mediceo (‘Genius of the Medici’), a bronze fountain statue that was made around 1557 in Florence by Bartolomeo Ammannati for the Duke of Tuscany, Cosimo I de’ Medici.

Understanding Degradation Mechanisms in Water‐In‐Salt Electrolyte. Part 2: Impact of the Electrochemical Parameters on the Cycling Behavior of LiFePO4 versus TiS2

open access: yesBatteries &Supercaps, EarlyView.
Cycling water‐in‐salt batteries involves complex degradation processes that require multiprobe analysis. Using online electrochemical mass spectrometry (OEMS), postmortem X‐ray photoemission spectroscopy (XPS) (including hard‐XPS), and scanning electron microscopy (SEM), the degradation mechanisms are examined in composite electrodes (TiS2 and LiFePO4)
