Electrically Conductive and Recyclable Biocomposite Coatings for Robotic Grippers and Touch Sensors

open access: yesAdvanced Intelligent Systems, EarlyView.
Sustainable robotics can reduce robot environmental impact by optimizing wear‐prone components, such as grippers and touch sensors, with recyclable materials and low‐energy manufacturing. Electrically conductive biocomposite coatings, made from biopolymers and carbon fillers, enable robust piezoresistive and piezocapacitive feedback.

Engineering Peripheral Metal‐Oxide Catalysis: Interparticle Spacing in Cu/ZrO2 Catalysts for Methanol Synthesis by CO2 Hydrogenation

open access: yesAngewandte Chemie, EarlyView.
The catalytically active periphery around oxide‐supported metal nanoparticles is key in reactions featuring marked metal‐oxide promotional effects. For Cu/ZrO2 CO2 hydrogenation catalysts, a Cu interparticle spacing of ∼15 nm optimizes methanol production rate and selectivity.

Quality of Life of Families Who Have Children With Cornelia de Lange Syndrome in Brazil: Opportunities for Improvement

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT This exploratory cross‐sectional study aimed to estimate the family quality of life (FQoL) among 70 Brazilian families with children with Cornelia de Lange syndrome (CdLS). Data were collected using sociodemographic and clinical data forms, the Barthel index for activities of daily living, and the Beach Center FQoL Scale, a 5‐point Likert tool

Spatially Engineered Ternary Schottky/S‐Scheme Heterojunctions for Artificial Photosynthesis

open access: yesAngewandte Chemie, EarlyView.
A spatially integrated Nb2C/Nb2O5/ZnO heterostructure couples Schottky and S‐scheme interfaces to promote directional charge separation and photothermal‐assisted CO2 activation, enabling efficient photoreduction without molecular cocatalysts or sacrificial agents through synergistic interfacial engineering and carrier dynamic control.

Synthesis of Crosslinked Biopolyesters Catalyzed by Natural Amino Acids

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Highly crosslinked bio‐polyesters were synthesized via the ROCOP reaction between epoxidized sunflower oil and biobased cyclic anhydrides. The resulting materials were comprehensively characterized by FT‐IR, TGA, and DSC. A cross‐linked network in the bio‐based polymers has been confirmed by dynamic mechanical analysis.

A Homobimetallic Frustrated Lewis Pair Cobalt Catalyst for the Methanolysis of Hydrosilanes

open access: yesAngewandte Chemie, EarlyView.
The bimetallic Co(I)/Co(–I) complex [Co(CO)2(κ3‐P,N,P‐PNHP)][Co(CO)4] shows excellent activities in the methanolysis of hydrosilanes, reaching TOF values of ca. 50 000 h−1. This behavior can be ascribed to the presence of the [Co(CO)4]– anion, which allows for a frustrated Lewis pair mechanism, resulting in a low energy pathway for the heterolytic ...

Nanostructured Biomaterial‐Based Approaches to Support Induced Pluripotent Stem Cell Differentiation

open access: yesAdvanced NanoBiomed Research, EarlyView.
Induced pluripotent stem cells (iPSCs), reprogrammed from adult somatic cells, represent an innovative approach for regenerative medicine and biomedical applications. This review highlights the importance of nanostructured biomaterials, utilized as delivery systems or scaffolds, in supporting iPSC differentiation and fate through structural and ...

Analytical Solutions of the Driven Time‐Dependent Jaynes–Cummings Model

open access: yesAnnalen der Physik, EarlyView.
Following the great strides made in the last decade towards the control and tunability of physical parameters in cavity quantum electrodynamics, this study presents new solutions to the dynamics of the time‐dependent Jaynes–Cummings model with variable external classical fields acting on the two‐level system and the quantized field mode.

Chitosan Hydrogels Crosslinked With Glutaraldehyde for Potential Toxic Elements Removal: Batch and Purification Device Analysis

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT The presence of toxic metal ions in contaminated wastewater raises significant concerns for human health. Three‐dimensional porous systems like hydrogels are being explored for contaminant removal. Still, there is a lack of understanding of their production parameters and performance.
