Molecular Cages as Probes in Indicator Displacement Assays: The Case of Scopolamine Detection
Angewandte Chemie, EarlyView.In this research, we show the concept of molecular cages as probes in indicator displacement assays, focusing on scopolamine detection, a drug often used in drug‐facilitated sexual assaults. Drug sensing occurs via the drug‐induced transformation of non‐emissive [Fluorescein2⊂Cage] complex into [Scopolamine⊂Catenane] and highly emissive free ...

, 2018 O presente trabalho buscou identificar e discutir alguns aspectos explorados nas aulas de Libras e suas implicações para o ensino e a aprendizagem de Química haja vista o material digital produzido por Benassi e Duarte (2016). Assim optou-se pela abordagem qualitativa, alinhada à técnica de Análise de Conteúdo, tendo como base os estudos de Silveira ...

Experimental Observation of a Calcium Silicon Double Carbonate
Angewandte Chemie, EarlyView.High‐pressure and ‐temperature reactions between Ca5(Si2O7)(CO3)2 tilleyite and CO2 carbon dioxide yield the first experimental evidence of the double carbonate Ca2Si(CO3)4 and a new Ca2(C4O10) phase containing tetrahedral [CO4] units. These findings reveal unexpected carbonate chemistry and highlight pathways for carbon incorporation under mantle ...

Advanced Energy and Sustainability Research, EarlyView.This study explores Cs2PtX6 (X = Cl, Br) lead‐free perovskites as sustainable photocatalysts for solar‐driven water splitting. Cs2PtBr6 outperforms Cs2PtCl6 in oxygen evolution due to its narrower bandgap and efficient charge carrier dynamics, enabling enhanced light absorption and charge separation.

Angewandte Chemie, EarlyView.The spontaneous assembly of triply chiral (L, Δ, P or D, Λ, M) cages has been achieved from a simple tripodal chiral effector based on phenylalanine tris(amidoamine), non‐chiral bipyridine dialdehyde, and a metal ion. Orthogonal imine bond and iron (II) coordination generate a single combination of chiral elements, while configurationally stable ...

The force of gravity in Schwarzschild and Gullstrand-Painlev\'e coordinates
, 2009 We derive the exact equations of motion (in Newtonian, F=ma, form) for test masses in Schwarzschild and Gullstrand-Painlev\'e coordinates. These equations of motion are simpler than the usual geodesic equations obtained from Christoffel tensors in that ...

Advanced Intelligent Discovery, EarlyView.Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.
