Dendritic Copper Current Collectors as a Capacity Boosting Material for Polymer-Templated Si/Ge/C Anodes in Li-Ion Batteries.

ACS Applied Materials and Interfaces
Dendritic copper offers a highly effective method for synthesizing porous copper anodes due to its intricate branching structure. This morphology results in an elevated surface area-to-volume ratio, facilitating shortened electron pathways during aqueous

Harnessing Imine Diversity To Tune Hyperbranched Polymer Degradation

, 2018
Dynamic-covalent chemistry has enabled the facile synthesis of a new generation of degradable materials, but controlling the rate at which these materials degrade remains elusive.

Glycopolymers with secondary binding motifs mimic glycan branching and display bacterial lectin selectivity in addition to affinity

, 2014
The application of synthetic glycopolymers to anti-adhesive therapies has so far been limited by their lack of lectin specificity. Here we employ a macromolecular engineering approach to mimic glycan architecture. A new, 3-step tandem post-polymerisation

Patchy polymer colloids with tunable anisotropy dimensions.

Journal of Physical Chemistry B, 2011
We present the synthesis of polymer colloids with continuously tunable anisotropy dimensions: patchiness, roughness, and branching. Our method makes use of controlled fusion of multiple protrusions on highly cross-linked polymer particles produced by ...

Stimuli-responsive hydrogels prepared by simultaneous “click chemistry” and metal–ligand coordination

, 2015
A novel strategy to synthesize stimuli-responsive metal-coordinated polymeric gels (MCPGs) via one-pot CuAAC and non-covalent metal coordination chemistry was demonstrated.

Effect of degree of branching on the thermoresponsive phase transition behaviors of hyperbranched multiarm copolymers: comparison of systems with LCST transition based on coil-to-globule transition or hydrophilic-hydrophobic balance.

Journal of Physical Chemistry B, 2010
This work reports for the first time the influence of degree of branching (DB) on the thermoresponsive phase transition behaviors of hyperbranched multiarm copolymers.

Hydrosoluble dendritic poly(ethylene oxide)s with zinc tetraphenylporphyrin branching points as photosensitizers

, 2013
Synthesis of dendrimer-like star-branched poly(ethylene oxide)s (PEOs) with two and three generations having Zn(II) tetraphenylporphyrin (ZnTPP) moieties at the core and at each branching point has been successfully achieved through an iterative ...

Role of branching architecture on the glass transition of hyperbranched polyethers.

Journal of Physical Chemistry B, 2009
The influence of branching architecture on the glass transition of hyperbranched polyethers has been investigated. For amorphous samples, the glass transition temperature (T(g)) first increases with the degree of branching (DB), passes through a maximum,
