Entropy and Information Approaches to Genetic Diversity and its Expression: Genomic Geography

open access: yesEntropy, 2010
This article highlights advantages of entropy-based genetic diversity measures, at levels from gene expression to landscapes. Shannon’s entropy-based diversity is the standard for ecological communities.

Double‐Interpenetrating Composite Bioink for Multi‐Component 3D Bioprinting and Biofabrication

open access: yesAdvanced Functional Materials, EarlyView.
Marine‐polysaccharides‐derived double interpenetrating network hydrogel‐based bioink, combining the attributes of physical and ionic crosslinking, enables room‐temperature bioprinting of mechanically defined structures that can be handled and are cytocompatible.

Atomic Layer Deposition Processes: Versatile Platforms for Engineering ZnO‐Chitosan Biointerfaces

open access: yesAdvanced Healthcare Materials, EarlyView.
Vapour phase metalation (VPM), multiplied pulsed vapour phase infiltration (MPI), and O2 plasma‑enhanced atomic layer deposition (PEALD) tailor Zn–chitosan (Zn‑CS) films. PEALD improves wettability and biocompatibility. MPI enhances semiconductor behavior. Antiseptic selectivity: VPM → E. coli; MPI → H. pylori.

Natural Biomaterials for Osteochondral Repair: From Source to Strategy

open access: yesAdvanced Healthcare Materials, EarlyView.
Biological origin‐guided overview of natural biomaterials and therapeutic strategies for osteochondral tissue engineering. The circular diagram categorizes representative materials and strategies into plant/algae‐derived, microbial‐derived, animal‐derived, and human‐derived sources, centered on an osteochondral defect repair model.

Subdivisions and Chromatic Roots

open access: yesJournal of Combinatorial Theory, Series B, 1999
In this short paper, the author proves that for any graph \(G\) and any \(\varepsilon>0\), there is a subdivision of \(G\) all of whose chromatic roots lie in \(|z-1|< 1+\varepsilon\). An interesting corollary follows from this result, viz. for any fixed positive \(\varepsilon\), there are large subdivisions of any graph for which the roots all lie in \

Soft, Degradable, and Magnetic Microcarriers for Encapsulation and Guided Transport of Drugs and 3D Spheroids

open access: yesAdvanced Materials, EarlyView.
This work presents soft, degradable hydrogel microcarriers that combine magnetic responsiveness with the ability to host multiple therapeutic and cellular components. Produced by droplet microfluidics, the carriers maintain structural integrity during manipulation, permit controlled breakdown under physiological conditions, and enable guided motion for

Sensitive and Spatially‐Resolved Electrochemiluminescence via Micropatterning

open access: yesAdvanced Materials Interfaces, EarlyView.
The use of a simple silica nanoparticle surface coating and patterning process can transform ordinary gold electrodes into multiplexed ECL sensing electrodes. Through spatially confined droplet formation and local ECL emission, it is possible to perform multiple analyses simultaneously from individual locations as well as intensify the ECL signal by as

Tunable 3D‐Printed Static Mixers for Gradient Bioprinting With High Cell Viability

open access: yesAdvanced Materials Technologies, EarlyView.
ABSTRACT The fabrication of native tissue‐like structures with gradual transitions in material properties, cell types, and growth factors remains a major challenge in biofabrication due to the lack of suitable methods. Mimicking the hierarchical organization of living tissues is essential for functional models, yet creating gradient, multimaterial ...

Tunable Extraordinary Optical Transmission in the Long‐Wavelength Infrared Range Using Electrostatic MEMS Actuation

open access: yesAdvanced Materials Technologies, EarlyView.
A MEMS‐integrated metamaterial filter enables continuous, low‐voltage spectral tuning in the long‐wavelength infrared (LWIR). The device employs extraordinary optical transmission in a dual suspended metasurface stack, where electrostatic actuation precisely controls the intermembrane air gap.
