Critical Exponents for Granular Phase Transitions

, 1997
The solid--fluid phase transition of a granular material shaken horizontally is investigated numerically. We find that it is a second-order phase transition and propose two order parameters, namely the averaged kinetic energy and the averaged granular ...

Additive Manufacturing of Hot Work Tool Steel by Laser Powder Bed Fusion Utilizing Powder Mixtures Including Grinding Chips: Assessing Chemical Homogeneity and Achievable Hardness

Advanced Engineering Materials, EarlyView.
Grinding chips of high‐alloyed steel are prepared to be admixed to a starting powder mixture for laser powder bed fusion. A three‐stage preparation is performed, including washing in acetone, magnetic separation, and ball milling. The addition of 30% of grinding chips to the powder mixture allows the fabrication of dense samples.

Variational finite-difference representation of the kinetic energy operator

, 2001
A potential disadvantage of real-space-grid electronic structure methods is the lack of a variational principle and the concomitant increase of total energy with grid refinement.

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

Advanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

In‐Situ Growth of 2D MOFs as a Molecular Sieving Layer on SnS2 Nanoflakes for Realizing Ultraselective H2S Detection

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The ultraselective H2S detection of the ZIF‐L/SnS2 heterostructure is demonstrated. The introduction of 2‐dimensional (2D) breathable ZIF‐L results in a substantial increase in H2S selectivity attributable to the molecular sieving effect, which impedes the permeation of gases with large kinetic diameters and high polarity.
