OcuPair, a Novel Photo‐crosslinkable PAMAM Dendrimer‐Hyaluronic Acid Hydrogel Bandage/Bioadhesive for Corneal Injuries and Temporary Corneal Repair

open access: yesAdvanced Science, EarlyView.
A schematic diagram showing the OcuPair adhesive hydrogel formulation loaded into the final delivery device and applied over the full‐thickness corneal wound in an in vivo rabbit model of corneal injury followed by in situ crosslinking to form a transparent hydrogel bandage sealing the wound.

Flexocatalytic Hydrogen Generation and Organics Degradation by Nano SrTiO3

open access: yesAdvanced Science, EarlyView.
Flexocatalysis, driven by non‐uniform strain‐induced electric polarization, overcomes piezocatalysis limitations, enabling versatile mechano‐catalytic applications. This study highlights the flexocatalytic activity of STO nanopowders, achieving significant hydrogen evolution (1289.53 µmol g−1 h−1) and ≈94% dye degradation.

Natural Toolbox–Chemical Engineering Aspect and High‐Value Applications of Janus Cellulose Nanomaterials

open access: yesAdvanced Science, EarlyView.
The Tai Ji symbol from China represents the co‐existence of two opposite substances, similar to quantum entanglement. The term Janus comes from ancient Roman religion and mythology. Janus, the god of beginnings, transitions, etc., has two faces, symbolizing duality. Janus cellulose nanomaterials show structural duality.

De novo assembly and characterization of bark transcriptome using Illumina sequencing and development of EST-SSR markers in rubber tree (Hevea brasiliensis Muell. Arg.)

open access: yesBMC Genomics, 2012
Background In rubber tree, bark is one of important agricultural and biological organs. However, the molecular mechanism involved in the bark formation and development in rubber tree remains largely unknown, which is at least partially due to lack of ...

Production of natural rubber from Para rubber tree

open access: yesPlant Biotechnology, 2009
Natural rubber is one of the most important polymers produced by plants because it is a strategic raw material used in more than 40,000 products. It has unique properties as a polymer owing to its specific structure, its high molecular weight and yet-to-be-defined contributions of minor components in the latex.

Secondary Electron Hyperspectral Imaging of Carbons: New Insights and Good Practice Guide

open access: yesAdvanced Science, EarlyView.
Secondary hyperspectral imaging of carbon surfaces is assessed with reference materials and in comparison to standard spectroscopies. Characterization of functional carbon materials from battery research reveals otherwise inaccessible information about the distribution of sp2 and amorphous carbon, as shown in graphite anode and carbon coated lithium ...

Transcriptome analysis reveals the molecular mechanisms of rubber biosynthesis and laticifer differentiation during rubber seed germination

open access: yesFrontiers in Plant Science
The molecular mechanisms underlying the initiation of natural rubber synthesis and laticifer differentiation have not been fully elucidated. In this study, we conducted a time-series transcriptome analysis of five rubber tree tissues at four stages of ...

Symmetry Breaking in Meniscus Splitting: Effects of Boundary Conditions and Polymeric Membrane Growth

open access: yesAdvanced Science, EarlyView.
Meniscus splitting in the drying of a viscous polymer dispersion is investigated by focusing on nucleation of multiple nuclei with symmetry breaking and asynchronous nucleus formation. Controlled by spatial boundaries, the first nucleus is generated at a position shifted away from the space center and strongly facilitates the asynchronous second ...

Photo‐Thermal Approaches on Polyimide Film for Demonstration of Sub‐50 µm Polymer Stencil Mask

open access: yesAdvanced Electronic Materials, EarlyView.
A photo‑thermal approach enables precise control of polyimide film properties during UV laser processing, achieving stencil mask fabrication with feature dimensions <50 µm—with the smallest features measuring 42.4 µm. This method maintains the polymer in its glassy state during processing, resulting in exceptional pattern stability and reproducibility.
