Smart‐Release Ion‐Exchanged Ca‐Montmorillonite for Corrosion Protection of AA2024 Aluminium Alloy

Advanced Materials Interfaces, EarlyView.
Smart‐release anticorrosion pigments based on Zn‐ and Mn‐modified montmorillonite were developed by ion exchange of Ca‐montmorillonite and evaluated for the protection of AA2024 aluminium alloy in artificial acid rain. Both modified pigments provided effective corrosion inhibition, with Zn‐modified montmorillonite (Zn‐MMT) achieving an inhibition ...

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

Advanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Successful Endoscopic Retrograde Cholangiopancreatography for Management of Choledocholithiasis in a Patient With Situs Inversus Totalis: A Case Report and Literature Review

Gastro Hep Advances
Situs inversus totalis is a rare congenital disorder defined by the transposition of all viscera to the opposite side of the body. Because of this anatomical alteration, endoscopic retrograde cholangiopancreatography (ERCP) in such a population is ...

Microfluidic Droplet Plate Preserving Single Human Induced Pluripotent Stem Cell‐Derived Cardiomyocytes Morphology and Function

Advanced Materials Technologies, EarlyView.
We introduce a novel method combining microfluidics, optogenetics, and human induced pluripotent stem cell (iPSC) technology to encapsulate single iPSC‐derived cardiomyocytes (iPSC‐CMs) in an optimal environment for functional characterization. This method enables direct genotype‐phenotype correlation for genetic studies and high‐throughput screening ...

Self‐Sealing Microneedles Improve Precision and Reduce Reflux in Subretinal Cell Transplantation

Advanced Materials Technologies, EarlyView.
Ultrafine 49G microneedles enable subretinal delivery of induced pluripotent stem cell‐derived retinal pigment epithelial cells through a 50 µm outer diameter tip. Compared with conventional 38G microcannulas, these microneedles reduce cell suspension reflux in a rabbit model, highlighting the potential of microinvasive delivery instruments to improve ...

Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

Advanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.
