Machine learning-driven low-velocity impact response prediction and multi-objective optimization of origami metamaterial sandwich

Baozha yu Chongji
Inspired by the hybrid topology design that integrates Miura origami and star-shaped honeycomb, this study proposes a novel origami metamaterial sandwich and employs machine learning to predict low-velocity impact response and perform multi-objective ...

Roll‐to‐Roll Processable EC/TC Hybrid Smart Windows Driven by a Bidirectional Dual‐Chromic Polymer Electrolyte

Advanced Functional Materials, EarlyView.
We present a scalable EC/TC hybrid smart window using a DCPE that enables tunable solar modulation (ΔTsol:15–43%), fast electrochromic switching (<90 s), and strong thermal blocking (10–14°C reduction). HPMC improves thermal stability, while an optimized ISL enhances EC performance.

Mechanical Programming of PEGDA‐β‐CD Polyrotaxane‐Based Hydrogels via Host–Guest Molecular Recognition

Advanced Functional Materials, EarlyView.
A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...

Load Distributing Metamaterials Via Discrete Optimization

Advanced Functional Materials, EarlyView.
Mechanical metamaterials are computationally optimized to homogenize transmitted forces by minimizing the spread of reaction forces. The resulting architectures transform localized loading into broader, more uniform force distributions and experimentally demonstrate robust load spreading under quasi‐static and impact loading.

Presented in Qom city and the antibiotic resistance Investigation of the prevalence of Arcobacter, Pseudomonas, Campylobacter and Bacillus cereus in sandwiches of the isolates

Bihdāsht-i Mavādd-i Ghaz̠āyī
Nowadays, due to the existence of different occupations, it is not possible to cook food for all the people of a society, and most of the people have turned to using ready-made foods, which, in addition to all its advantages, can be a source of They are ...

Programmable Soft Actuator with Multi‐Responsiveness Based on Conductive MOF‐Liquid Crystal Polymer Composite

Advanced Functional Materials, EarlyView.
A sequential dual‐alignment strategy independently programs the orientation of conductive metal‐organic framework (c‐MOF) microrods and liquid crystals within a composite film. This approach creates an asymmetric bilayer structure that enables precise, multi‐responsive actuation.

Prevalence of contamination of sandwiches with pathogenic microorganisms and antibiotic resistance of isolates in Kermanshah city, Iran.

Bihdāsht-i Mavādd-i Ghaz̠āyī
Meat products are one of the suppliers of human food needs, and like other food products, they have special nutritional values. If these products are contaminated with pathogenic microorganisms, they cause gastroenteritis in humans.

Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly

Advanced Functional Materials, EarlyView.
Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...

Modal Analysis of Light Propagation, Polarization and Diffraction by Cholesteric Liquid Crystal Layers

Advanced Functional Materials, EarlyView.
The analysis of optical eigenmodes in chiral liquid crystal with perpendicular or tilted helical axis, and their correspondence with the external medium, leads to an intuitive understanding of the angle and wavelength dependency of transmissive and reflective diffraction.

Indirect comparisons of tucatinib in combination with trastuzumab for patients with previously treated HER2–positive metastatic colorectal cancer

Journal of Comparative Effectiveness Research
Aim: In the single-arm MOUNTAINEER trial (NCT03043313) tucatinib in combination with trastuzumab showed an objective response rate (ORR) of 39.3% in patients with previously treated, HER2+unresectable or metastatic colorectal cancer (mCRC).
