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 ...

Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

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.

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 ...

Determinação do nível de lisina na fase inicial-II do crescimento de suínos, através da composição química e deposição de tecidos e efeitos na terminação

Boletim de Indústria Animal, 2013
Trinta suínos híbridos comerciais, machos castrados e fêmeas foram amostrados de um experimento de desempenho e abatidos para determinar a composição química das frações corporais e taxas de deposição protéica e lipídica na carcaça e corpo vazio.

Enhancing Sensitivity across Scales with Highly Sensitive Hall Effect‐Based Auxetic Tactile Sensors

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Herein, a tactile sensor based on hall‐effect sensors with an auxetic structure, called Hall effect‐based auxetic tactile sensor (HEATS), is proposed. The change in magnetism resulting from the deformation of the auxetic structure is utilized for sensing.

Stereospecific Assembly of Triply Chiral Pseudopeptidic Cages Through Dynamic Dual Chirality Transfer

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 ...

<b>Caracterização físico-química e composição de barras de cereais fortiï¬cadas com ferro<br>Physico-chemical and nutritional characterization of cereal bars fortiï¬ed with iron</b>

Alimentos e Nutrição, 2011
<p align="justify"> A deï¬ciência de ferro é a carência nutricional mais comum no mundo. Para preveni-la, a fortiï¬ cação de alimentos com ferro tem sido recomendada. Contudo, é preciso conhecer as características dos ingredientes que compõem o alimento, veriï¬ car a presença de inibidores da absorção de ferro e as propriedades dos ...

Elektrochemischer Schutz von Cyanobakterienzellen vor molekularem Sauerstoff ermöglicht nachhaltige PhotoH2‐Produktion

Angewandte Chemie, EarlyView.
Photosynthetische Mikroorganismen können zur lichtgetriebenen H2‐Entwicklung genutzt werden. Eine Einschränkung ist jedoch die damit verbundene Bildung von molekularem Sauerstoff als Nebenprodukt der Photosynthese, der die Aktivität des Biokatalysators für die H2‐Produktion, d. h. die Hydrogenase, inhibiert.
