Layer-by-layer self-assembly of porphyrin heterogeneous metal-organic thin films on titanium oxide for photocurrent generation

, 2013
Dye-sensitized solar cells (DSSCs) are a class of solar cells of the third generation. DSSCs are cheap and simple to fabricate, exhibit flexible properties, and are not limited by the Shockley-Queisser limit of semiconductor junction solar cells.

pH-Triggered release from surface-modified poly(lactic-co-glycolic acid) nanoparticles

Beilstein Journal of Nanotechnology, 2015
Nanoparticles (NP) of poly(lactic-co-glycolic acid) (PLGA) represent a promising biodegradable drug delivery system. We suggest here a two-step release system of PLGA nanoparticles with a pH-tunable polymeric shell, providing an initial pH-triggered step,

Dye‐Initiated Chirped Cholesteric Polymer Networks Exhibiting Broadband Dissipative Chiral Photonic Bands

Advanced Functional Materials, EarlyView.
A dye‐based photoinitiator acting as a structure‐directing element, guides the formation of a cholesteric polymer network that behaves as a chirped photonic structure with dissipative chiral coupling. Photopolymerization freezes a depth‐dependent helical pitch, broadening the Bragg resonance spectrum.

Layer-by-Layer Assembly of High-Performance Electroactive Composites Using a Multiple Charged Small Molecule

, 2019
Layer-by-layer (LbL) assembly is a versatile tool for fabricating multilayers with tailorable nanostructures. LbL, however, generally relies on polyelectrolytes, which are mostly insulating and induce large interlayer distances.

MXene Wrapped Magnetic Mesocrystals for Durable Redox Catalytic Cancer Therapy and Responsive MRI

Advanced Functional Materials, EarlyView.
Conformal wrapping of ultrathin Ti3C2Tx MXene nanosheets on Fe3O4 mesocrystals creates topology‐stabilized Schottky junctions that direct photoinduced electron transfer under NIR irradiation. The unique architecture sustains Fenton catalysis, promotes continuous hydroxyl radical production, and provides photo‐responsive MRI contrast.

Layer-by-Layer Self-Assembly Marine Antifouling Coating of Phenol Absorbed by Polyvinylpyrrolidone Anchored on Stainless Steel Surfaces

Journal of Marine Science and Engineering
Marine biofouling is a major problem that contributes to the failure of man-made marine structures. Conventional marine antifouling coatings that release heavy metal ions for antimicrobial purposes are no longer in line with today’s environmental issues.
