Enhanced Oxidation and Thermal Shock Resistance of N‐type Mg2Si0.89(Sn0.1,Sb0.01) Thermoelectric Material via Cr0.9Si0.1 Coating

open access: yesAdvanced Engineering Materials, EarlyView.
Cr0.9Si0.1 protective coatings are developed to enhance the thermal‐shock and oxidation resistance of Mg2Si0.89(Sn0.1,Sb0.01) thermoelectric (TE) materials. The coating forms a dense and adherent barrier that suppresses oxygen diffusion and mitigates mechanical degradation during cyclic oxidation, demonstrating its potential to improve the long‐term ...

Dissipative flow and vortex shedding in the Painlev\'e boundary layer of a Bose Einstein condensate

open access: yes, 2003
Raman et al. have found experimental evidence for a critical velocity under which there is no dissipation when a detuned laser beam is moved in a Bose-Einstein condensate. We analyze the origin of this critical velocity in the low density region close to

Can Ti‐Based MXenes Serve as Solid Lubricants for Brake Applications? A Tribological Study

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the first implementation of Ti‐based MXenes materials in brake pad friction composite material. The resulting composite material exhibits a 48% reduction in the wear rate; alongside significant improvements are observed for thermal and mechanical properties.

Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Is there a relationship between fingerprint donation and DNA shedding? [PDF]

open access: yes, 2009
This research investigates the possible relationship between fingerprint donation and DNA shedding. Volunteers were asked to provide a series of fingerprint depletions on glass. The level of fingerprint detail developed and DNA profiling results obtained

Intramolecular Down‐ and Up‐Conversion in Dimeric Tetracene Complexes Centered via Platinum(II) and Palladium(II)

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐tetracene dimeric complexes are synthesized through the pyridyl coordination to either Pt(II) or Pd(II). Photophysical properties are systematically compared as a function of the metal using steady‐state and time‐resolved spectroscopy. The Pt(II) dimer exhibits efficient intramolecular singlet fission and subsequent intramolecular up‐conversion ...
