Preparation of Few-Layer Graphene Dispersions from Hydrothermally Expanded Graphite

Applied Sciences, 2019
In this study, we propose a novel approach to prepare few-layer graphene (FLG) dispersions, which is realized by exfoliating natural graphite flakes in a surfactant aqueous solution under hydrothermal treatment and liquid-phase exfoliation.

Structures of Aqueous Dispersions of Phosphatidylserine

Journal of Biological Chemistry, 1973
Abstract Dilute (g10% w/v) unsonicated phosphatidylserine dispersions in H2O contain spherical particles of a wide size distribution (0.1 to 15 µm). The majority have diameters between 0.1 to 2 µm and lack the multilamellar arrangement of bilayers typical of unsonicated lecithin dispersions. Sonication produces small thermodynamically unstable vesicles

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
