Programmable Metamaterials with Perforated Shell Group Supporting Versatile Information Processing

Advanced Science, EarlyView.
This study proposes a novel mechanical metamaterial with high‐density memory based on multi‐stable perforated shells to realize multi‐layer information encoding, storage, decoding, and reading. The metamaterial can perform more application‐oriented tasks to process information, such as encryption and dynamic behavior regulation, which hopefully enables

An Unusual Case of Perforation Peritonitis: A Diagnostic DilemmaBacterial or Parasitic? [PDF]

National Journal of Laboratory Medicine, 2018
Large intestinal perforation due to mixed parasitic and bacterial aetiology is a rare entity. We report the case of a 63 years old man, who underwent a therapeutic paracentesis for ascites, which revealed eggs of hookworm, along with E.coli.

Mathematical Modeling of Transport and Degradation of Feedstuffs in the Small Intestine [PDF]

Journal of Theoretical Biology 294 (2012) 114-121, 2011
We describe a mathematical modeling of the digestion in the small intestine. The main interest of our work is to consider, at the same time, different aspects of the digestion i.e. the transport of the bolus all along the intestine, feedstuffs degradation according to the enzymes and local physical conditions, and nutrients absorption.

Ti3C2Tx MXene‐Zirconium Diboride Based Ultra‐High Temperature Ceramics

Advanced Science, EarlyView.
This study demonstrates the effectiveness of Ti3C2Tx MXenes as additives in ultra‐high‐temperature ceramics (ZrB₂), enhancing densification, reducing oxygen content, and improving mechanical properties. Through surfactant‐free electrostatic self‐assembly and spark plasma sintering, MXenes enabled the formation of a core–shell microstructure, resulting ...

Cartilage‐Penetrating Framework Nucleic Acid Nanoparticles Ameliorate Osteoarthritis by Promoting Drug Delivery and Chondrocyte Uptake

Advanced Science, EarlyView.
Based on the poor cartilage penetration of tFNA, a novel tFNA‐2WL with excellent cartilage permeability and perfect chondrocyte endocytosis properties is designed and fabricated. As a result, tFNA‐2WL has a nearly seven‐fold increase in the penetration depth into the cartilage, with the same excellent cell entry properties as tFNA.
