Copper-Catalyzed C(sp3)–H Methylation via Radical Relay

open access: yes
The methyl moiety is a key functional group that can result in major improvements in the potency and selectivity of pharmaceutical agents. We present a radical relay C–H methylation methodology that employs a β-diketiminate copper catalyst capable of ...

Suppression of Copper Thin Film Loss during Graphene Synthesis

open access: yes, 2016
Thin metal films can be used to catalyze the growth of nanomaterials in place of the bulk metal, while greatly reducing the amount of material used. A big drawback of copper thin films (0.5–1.5 μm thick) is that, under high temperature/vacuum synthesis ...

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

open access: yesAdvanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Incorporation of Selenium into Sol–Gel‐Derived Bioactive Glass: Influence on Glass Structure, Bioactivity, and its Selective Cytotoxicity

open access: yesAdvanced Engineering Materials, EarlyView.
Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

Copper and zinc ligands of pisum sativum and expression of psMT(_A) [PDF]

open access: yes, 1995
The gene, PsMT(_A) is highly expressed in the roots of the garden pea, Pisum sativum. The predicted primary structures of homologues of the PsMT(_A) gene from a range of plant species were compared. Common features are amino and carboxyl terminal domains
