Virus‐Mediated Self‐Assembly of Functional Cyclodextrins for Antiviral Inhibition
Angewandte Chemie, EarlyView.A sialic acid (SA)‐functionalized cyclodextrin (CD) self‐assembles on SARS‐CoV‐2 through ligand–receptor recognition, nucleating cooperative supramolecular polymer growth that blocks infection. The adaptive assembly requires both ligand binding and host–guest polymerization, remains active across variants, and can be tuned by coassembly, establishing ...

Reminiscências da primeira mestra de d. Pedro II: Mariana Carlota de Verna
Revista Educação em Questão, 2022 O estudo aborda a trajetória de Mariana Carlota de Verna como primeira mestra de d. Pedro II, e o que a levou, posteriormente, a receber o título de condessa de Belmonte. O objetivo central é evidenciar as circunstâncias em que assumiu o cargo de preceptora do herdeiro do trono do Brasil e algumas das dificuldades que enfrentou para se manter nele até ...

Continuous‐Flow Microfluidic Synthesis Enhances C2+ Selectivity for Cu2O Catalysts
Advanced Science, EarlyView.Microfluidic devices are used to prepare Cu2O nanoparticles under laminar flow conditions, which exhibit enhanced selectivity in the CO2‐to‐C2+ reaction due to their nanoporosity and high defect concentration. Cu2O prepared using standard solution methods displays decreased CO2‐to‐C2+ selectivity due to the absence of similar properties. Altogether, we

Angewandte Chemie, EarlyView.Outstanding catalytic results for NH3 decomposition for H2 production were obtained with metallic Ru, Rh, and RuRh nanoparticle‐exsolved CeO2‐based catalysts. Significant lower amounts of available superficial metallic fractions were needed in comparison to conventional Ru‐impregnated materials.

Engineering a Correlated Narrow‐Gap Semiconductor: Effects of Ga Substitution in EuZn2P2
Advanced Electronic Materials, EarlyView.ABSTRACT The effect of Ga substitution on the electronic, magnetic, and low‐energy responses of the Zintl phase EuZn2P2${\rm EuZn}_2 {\rm P}_2$ is investigated by electrical transport, electron spin resonance (ESR), and terahertz time‐domain spectroscopy (THz‐TDS). Incorporating Ga into EuZn2P2${\rm EuZn}_2 {\rm P}_2$ (EuZn1.8Ga0.2P2${\rm EuZn}_{1.8} {\

São Pedro, uma Igreja do Brasil no Egito
Revista de História, 1966 O Brasil e o Egito, dois países tão distantes, mas que, em virtude do interêsse de D. Pedro II, pela terra dos Faraós, tornaram-se espiritualmente próximos no que diz às tradições é ao seu passado. Estão em hemisférios opostos, mas em latitudes idênticas,

Large‐Scale Machine Learning to Screen for Small‐Molecule Senolytics
Advanced Intelligent Discovery, EarlyView.A consistent workflow underpins all experiments in this study. A dedicated model‐selection dataset first identifies optimal hyperparameters for each algorithm. Models are then trained and rigorously evaluated on independent sets of molecules using the senolytic ratio SR. Comprehensive hyperparameter exploration across SMILES representations, task types,
