Intramolecular Down‐ and Up‐Conversion in Dimeric Tetracene Complexes Centered via Platinum(II) and Palladium(II)

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐tetracene dimeric complexes are synthesized through the pyridyl coordination to either Pt(II) or Pd(II). Photophysical properties are systematically compared as a function of the metal using steady‐state and time‐resolved spectroscopy. The Pt(II) dimer exhibits efficient intramolecular singlet fission and subsequent intramolecular up‐conversion ...

Hydraulic conductivity of a dense prehydrated geosynthetic clay liner [PDF]

open access: yes, 2015
Dense prehydrated geosynthetic clay liners (DPH-GCLs) are a particular type of GCL which, unlike conventional GCLs manufactured with dry bentonite, contain bentonite prehydrated during manufacturing.

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

open access: yesAdvanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

Adsorption and Permeation Events in Molecular Diffusion

open access: yesMolecules
How many times can a diffusing molecule permeate across a membrane or be adsorbed on a substrate? We employ an encounter-based approach to find the statistics of adsorption or permeation events for molecular diffusion in a general confining medium ...

Gliadin Peptide Facilitates FITC Dextran Transport across the Non Everted Gut Sac of Rat Small Intestine

open access: yesScientia Pharmaceutica, 2018
Superoxide dismutase (SOD) is an antioxidant protein. When administered orally, it has low bioavailability due to its low permeation. In a previous study we fused gliadin peptide P51 (LGQQQPFPPQQPYPQPQPF) and gliadin peptide P61 (QQPYPQPQPF) with SOD ...
