Tailoring the Properties of Functional Materials With N‐Oxides

open access: yesAdvanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Synthetic Amphoteric Polypeptide. III. A Water-Soluble Amphoteric Polypeptide [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1958
Abstract 1. Preparation of four copoly-(l-glutamic acid, Dl-serine), the molar ratios of the two amino acid residues were 4:1, 3:2, 2:3 and 1:4, by debenzylation of the corresponding four copoly-(γ-benzyl l-glutamate, O-benzyl Dl-serine), was attempted. 2. The inter- and/or intra-molecular ester-linkages, formed during the

Durable Physically Mixed Microporous and Mesoporous MOFs/Nanofiber Aerogel 3D Composites for Effective Toxic Gas Capture and Organophosphonate Detoxification

open access: yesAdvanced Functional Materials, EarlyView.
Ultralight 3D nanofibrous aerogels embedded with metal‐organic frameworks effectively capture and neutralize toxic gases and organophosphonates. Incorporating mesoporous UiO‐66‐NH2 and HKUST‐1 into PAN/PVP fibers enables high MOF loading while maintaining mechanical strength and structural stability.
