Beyond Thin Film Limits—Superhard and Hydrogen‐Free Amorphous Carbon Coatings With Over 100 µm Thickness

open access: yesAdvanced Functional Materials, EarlyView.
For the first time, an extreme‐thick laser‐arc PVD ta‐C (DLC) coating exceeding 100 µm is demonstrated, opening up new possibilities for ultra‐high load bearing capacity. This superhard amorphous carbon architecture combines >50% sp3 bonding, robust adhesion and self‐supporting performance, shielding substrates from plastic flow under extreme contact ...

Dynamic Observation of Lacy Pattern Formation in a Bone Tissue Model Using Liquid Phase Scanning Transmission Electron Microscopy

open access: yesAdvanced Functional Materials, EarlyView.
Here, we establish a low‐dose liquid‐phase electron microscopy workflow for real‐time observation of biological processes in hydrated conditions. Beam damage is reduced by imaging only 20% of the pixels and reconstructing the complete image using an inpainting algorithm.

Multidimensional‐Encoded High‐Fidelity Spectrometers With a Floating‐Base Bipolar Junction

open access: yesAdvanced Functional Materials, EarlyView.
A floating‐base bipolar junction photodetector enables multidimensional spectral encoding through synergistic gate‐ and drain‐bias modulation of interfacial barrier matching. The resulting complementary spectral responses form a diverse, weakly correlated response matrix, enabling robust and high‐fidelity spectral reconstruction even at sub‐nanoampere ...

The effects of leaf size and varied calcium nitrate levels on gloxinia leaf-disk explants [PDF]

open access: yes, 1980
Uniform disks cut from three leaf sizes of florist\u27s gloxinia (Sinningia speciosa \u27Cherry Bell\u27) were placed on Knop\u27s media containing five concentrations of calcium nitrate. After 10 weeks of growth on the culture medium, dry weights of the

Endosomal Escape of siRNA Polyplexes: A Molecular Dynamics Perspective on Underlying Mechanisms

open access: yesAdvanced Functional Materials, EarlyView.
Molecular dynamics simulations reveal distinct endosomal escape mechanisms of siRNA nanoparticles, ranging from electrostatic membrane attachment to hydrophobic membrane fusion. Hydrophobic residues and anionic endosomal lipids emerge as key determinants of membrane disruption, linking molecular interactions to experimental delivery performance and ...

Constant leaf-size hierarchy of three-dimensional alternating turing machines [PDF]

open access: yes, 1999
‘Leaf -size ’(or‘branching ’) is the minimum number of leaves of some accepting computation trees of alternating devices. For example, one leaf corresponds to nondeterministic computation.

Programming Neuromorphic Plasticity Through Ionic and Electronic Coupling in Organic Electrochemical Transistors

open access: yesAdvanced Functional Materials, EarlyView.
Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Hydrogel‐Based Method for High‐Resolution Measurements of Contact Mechanics in Rapid Biological Adhesives: A Case Study in Cuttlefish Tentacle Strikes

open access: yesAdvanced Functional Materials, EarlyView.
Cuttlefish and squid can catch their prey within milliseconds using specialized tentacles and suckers. The physics of how the suckers can attach so quickly has remained a mystery given the technical challenges of studying them in vivo. In this publication, we develop a hydrogel that retains imprints of the suckers in order to estimate the forces they ...

On the estimation of leaf size and crown geometry for tree canopies from hotspot observations

open access: yes, 1997
A computer-graphic based model for radiation interception in vegetation canopies is used to investigate the feasibility of estimating leaf size and crown size,for deciduous and coniferous trees,from canopy reflectance in the hotspot region.For deciduous ...
