Assessing the Microstructure of SnBiZn Alloys during Semisolid Treatment
The development of Sn‐based alloys for semisolid processing is crucial for Industry 4.0. This study investigates Sn40Bi and Sn40Bi2Zn alloys, revealing that Zn refines Sn‐rich globules by pinning dendrite boundaries. Bi saturation occurs at 60 min, while Zn enhances globule microhardness at 90 min through solid solution strengthening.

An asymmetric non‐fullerene acceptor BTP‐FT is developed by extending the end group of Y6‐BO with thiophene. The conformation of the molecule is determined by the noncovalent F···S interaction as demonstrated by 2D NMR and simulations. An efficiency of 18.39% is achieved in the resulting ternary solar cells processed from toluene.

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions
A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...

The Reverse Brazil Nut Problem: Competition between Percolation and Condensation [PDF]
In the Brazil nut problem (BNP), hard spheres with larger diameters rise to the top. There are various explanations (percolation, reorganization, convection), but a broad understanding or control of this effect is by no means acheived. A theory is presented for the crossover from the BNP to the reverse Brazil nut problem (RBNP) based on a competition ...

Colloidal brazil nut effect in sediments of binary charged suspensions [PDF]
Equilibrium sedimentation density profiles of charged binary colloidal suspensions are calculated by computer simulations and density functional theory. For deionized samples, we predict a colloidal ``brazil nut'' effect: heavy colloidal particles sediment on top of the lighter ones provided that their mass per charge is smaller than that of the ...

DO "CONHECE-TE A TI MESMO" AO "TORNA-TE QUEM TU ÉS": NIETZSCHE CONTRA SÓCRATES EM ECCE HOMO
A partir de uma passagem interessante da autobiografia do filósofo, trabalharemos dois imperativos gregos, o “Conhece-te a ti mesmo”, do oráculo de Delfos, e o “Torna-te o que tu és”, do poeta Píndaro.
