Selective Separation of the Rare Earth Elements Dysprosium and Neodymium via Tailoring Nanocellulose Chemical Structure

open access: yesAdvanced Functional Materials, EarlyView.
Dicarboxylate‐modified anionic hairy cellulose nanocrystals exhibit a high selectivity for dysprosium(III) over neodymium(III). This selectivity arises from disordered dicarboxylate cellulose “hairs” that enable cooperative ionic coordination, hydrogen bonding, and strain‐induced conformational shrinkage.

Ecology and management of cottontail rabbits in Missouri (2014) [PDF]

open access: yes, 2014
Cottontail rabbits (Sylvilagus floridanus) have long been one of the most popular game species across rural Missouri (Figure 1). Cottontails are also common in urban and suburban areas. They have the capacity to produce several litters of young in a year,

Dense Nanofibrillar Collagen–Silica Hybrids with High Strength and ECM‐Mimetic Tissue Integration

open access: yesAdvanced Functional Materials, EarlyView.
Dense nanofibrillar collagen–silica hybrids are engineered by synchronizing collagen fibrillogenesis with silica condensation, producing printable scaffolds that unexpectedly approach native extracellular matrix organization and strength. These cell‐free constructs guide endogenous cell‐infiltration, enable localized matrix remodeling, and integrate ...

Forage Brassica Variety Trial [PDF]

open access: yes, 2013
Forage brassica can provide a near-concentrate type diet late in the grazing season. This allows for an extra grazing opportunity after annual row crops are harvested, and establishes forage to fill a gap in feed quality and supply.

Weak reducing disks and disk surgery [PDF]

open access: yesJournal of Knot Theory and Its Ramifications, 2018
Let [Formula: see text] be an unknot in [Formula: see text]-bridge position in the [Formula: see text]-sphere. We give an example of a pair of weak reducing disks [Formula: see text] and [Formula: see text] for [Formula: see text] such that both disks obtained from [Formula: see text] ([Formula: see text]) by a surgery along any outermost disk in ...

3D‐Printed Porous Hydroxyapatite Formed via Enzymatic Mineralization

open access: yesAdvanced Functional Materials, EarlyView.
Bone combines lightness, strength, and the ability to heal, inspiring new materials design. This work introduces a room‐temperature, enzyme‐mediated 3D printing method to create porous hydroxyapatite scaffolds. The process avoids energy‐intensive sintering, preserves bioactivity, and allows control over porosity and mineralization.

Dual‐Interface‐Dominant Cathode Architectures Enabling Fast Sulfur Redox and Stable Interfaces in All‐Solid‐State Li‐S Batteries

open access: yesAdvanced Functional Materials, EarlyView.
An optimized carbon host nanostructure enables a dual‐interface‐dominant architecture in sulfur cathodes of solid‐state Li‐S batteries by selectively forming sulfur|carbon and sulfur|solid electrolyte interfaces. This tailored interfacial configuration accelerates sulfur redox kinetics by establishing enriched Li+/e– transport networks, while ...
