Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

open access: yesAdvanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

open access: yesAdvanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

The collection of Tuvan stamps (1926–1943) in the National Museum of the Republic of Tuva and the prospects of philately in Tuva

open access: yesНовые исследования Тувы, 2016
Stamps of the People’s Republic of Tuva (PRT, 1921-1944) as indicia and as items of collectors’ interest, are universally renowned, and as such have been the subject of a good deal of research. These works contain more than a mere story of Tuvan stamps –

Postage Due: Stewardship, Stamps and a Watch Pocket [PDF]

open access: yes, 2014
Why do we forget that people are human? I\u27ve been asking myself that question more and more lately. Partially it\u27s driven by a laundry list of things happening in the world, vitriolic attacks on humanity, both strangers and friends.

Microporous Microgel Assemblies Facilitating the Recruitment and Osteogenic Differentiation of Progenitor Cells for Bone Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.
