Polymorphic Superparaelectric Engineering Boosting Energy Storage Capacity in BaTiO3‐Based Ceramics

Advanced Science, EarlyView.
Herein, Ca2+ incorporation promotes the coexistence of CaTiO3‐/BaTiO3‐derived paraferroelectric states, stabilizing cubic‐orthorhombic‐tetragonal polymorphic superparaelectric phases. This minimizes polarization energy barriers, facilitating full polarization saturation without compromising efficiency.

First principles based atomistic modeling of phase stability in PMN-xPT

, 2011
We have performed molecular dynamics simulations using a shell model potential developed by fitting first principles results to describe the behavior of the relaxor-ferroelectric (1-x)PbMg1/3Nb2/3O3-xPbTiO3 (PMN-xPT) as function of concentration and ...

Can Machine Learning Reduce Unnecessary Surgeries? A Retrospective Analysis Using Threshold Optimization to Prevent Negative Appendectomies in Adults

Annals of Gastroenterological Surgery, EarlyView.
Threshold‐optimized machine learning models using routine clinical and laboratory data in 623 adults undergoing appendectomy. Logistic regression (AUC = 0.765) and random forest (AUC = 0.785) were the best‐performing models for appendicitis detection and complicated appendicitis prediction, respectively.

Structural and Biological Insights Into Copper(I) Phosphane Complexes With Boron‐Phenylated Poly(3‐(CF3)Pyrazolyl)‐ and Poly(6‐(CF3)‐2‐pyridyl)‐Borates

Chemistry – A European Journal, EarlyView.
This study reports six new copper(I) complexes with unusual coordination and strong anticancer activity against a panel of human cancer cell lines derived from different solid tumors. The most active compounds outperform cisplatin, even in resistant cells, by inhibiting protein disulfide isomerase and inducing redox stress that triggers non‐apoptotic ...
