Tailoring π-conjugation and vibrational modes to steer on-surface synthesis of pentalene-bridged ladder polymers

open access: yesNature Communications, 2020
Development of strategies for the synthesis of pi-conjugated polymers is hampered by limited solubility. Here, the authors report a synthetic protocol based on the search for specific vibrational modes through an appropriate tailoring of the p ...

Gravitational Faraday holonomy

open access: yesThe European Physical Journal C
Abstract Closed optical trajectories in Kerr spacetime are engineered to exhibit a marked lack of symmetry. The eccentricity manifests as a holonomy in gravitational Faraday rotation that can be made arbitrarily large by radial translation of the common location of source and receiver. All trajectories are non-equatorial and include a passage

Tri‐Modal Anticancer Strategies with Doxorubicin‐Loaded Iron Oxide Nanoparticles Integrating Chemo and Magneto‐Photothermal Therapeutic Effects

open access: yesAdvanced NanoBiomed Research
In this study, the potential of maghemite (γ‐Fe2O3) nanoparticles (MNPs) functionalized with doxorubicin (DOX) is explored for chemo‐magneto‐photothermal therapy in cancer treatment. MNPs are functionalized through electrostatic interactions or disulfide

Phase Boundary Engineering of Co2P‐CoP Branched Nanoparticles Enhances Cobalt Oxidation for Oxygen Evolution Electrocatalysis

open access: yesAdvanced Materials, EarlyView.
Phase boundaries between Co2P and CoP are constructed through a controlled transformation of Co to Co2P‐CoP branched nanoparticles. The polycrystalline mixed‐phase Co2P‐CoP branches are enriched with phase boundaries that stabilize Co active sites for OER. This work highlights phase boundary engineering as a powerful approach to tailor active sites and
