Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.

A few words of delight [PDF]

open access: yesJužnoslovenski Filolog, 2005
Lith. lokšniis "tender, etc" is traced back, by way of dissimilation, to *losk-snii-, derived with the adjectival suffix -snii-, productive in Baltic, from the I.-E. stem of Slavic laska, Lat. lasc-tvus, etc.

Characterization of an Injectable Poly(vinyl alcohol)‐gelatin Hydrogel for Growth Factor Delivery in an Orthopedic Application

open access: yesAdvanced Healthcare Materials, EarlyView.
This work introduces photo‐crosslinkable tyraminated poly(vinyl alcohol)‐gelatin (PVA‐GT) hydrogels as tunable injectable platforms for tissue engineering and growth factor delivery applications. This schematic illustrates the two developed hydrogel formulations and the experimental workflow used to evaluate their physico‐chemical properties in vitro ...

A two-stage, two-organism process for biohydrogen from glucose [PDF]

open access: yes, 2006
H2 can potentially be produced in a two-stage biological process: the fermentation of glucose by Escherichia coli HD701 and the photofermentation of the residual medium by Rhodobacter sphaeroides O.U. 001. In a typical batch fermentation, E.

Diels‐Alder Click Chemistry as a Dynamic‐Covalent Crosslinking Method in Spheroid‐Encapsulating Hydrogels for Cartilage Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This research shows the development of hydrogels with Diels‐Alder click chemistry for engineering cartilage‐like tissue. The hydrogels support cartilage spheroids which could be cultured for at least 28 days. Furthermore, the spheroids showed a tendency to fuse together into a more consistent construct, and produced important components needed for ...

Complejidad semántica y contexto

open access: yesEstudios de Lingüística, 1993
Linguistics has neglected the variety of systems at work in every text. These systems can be described according to four orders: syntagmatic, paradigmatic, referential, and hermeneutic.

Microbial carbon use efficiency: accounting for population, community, and ecosystem-scale controls over the fate of metabolized organic matter [PDF]

open access: yes, 2016
Microbial carbon use efficiency (CUE) is a critical regulator of soil organic matter dynamics and terrestrial carbon fluxes, with strong implications for soil biogeochemistry models.

Supramolecular Engineering of Fluid Pressure in Filamentous Hybrid Double Network Hydrogels for 3D Chondrocyte Culture

open access: yesAdvanced Healthcare Materials, EarlyView.
Inspired by the water‐rich and interconnected biopolymer networks of native load‐bearing tissues, we disclose a connectable design for a hybrid filamentous supramolecular and covalent double network hydrogel generated through in situ photopolymerization.

A Type of Reduplication in Turkish

open access: yesKansas Working Papers in Linguistics, 1990
This is an attempt to describe one of several types of reduplication in Turkish, based on a piece of data elicited from 32 native speakers.* What was known as irregular case revealed itself as a complicated pattern of dissimilation.

Varying Means of Grammatical Parallelism in the Church Slavonic Translations of Psalms of the 11 th –16 th Centuries

open access: yesВестник Волгоградского государственного университета: Серия 2. Языкознание, 2020
As a metrically organized poetic text, the Psalter is built on the principle of substantive and formal parallelism of verses and stanzas in the Hebrew text as well as in Greek and Church Slavonic translations.
