Toward Fast Proton Shuttling in Acidic Oxygen Evolution Reaction

Advanced Functional Materials, EarlyView.
This review establishes proton transfer dynamics as a descriptor governing acidic OER activity, moving beyond the kinetic constraints derived from the proton coupled electron transfer. We discuss how deprotonation governs classical mechanisms, including adsorbate evolution mechanism (AEM), lattice oxygen mechanism (LOM) and oxide path mechanism (OPM ...

Genipin‐Crosslinked, Silane‐Anchored 3D Tumor–Stroma Microtissues for High‐Content On‐Chip Drug Testing

Advanced Healthcare Materials, EarlyView.
We describe a microfluidic tumor‐stroma co‐culture model, engineered to resist collagen‐hydrogel contraction driven by fibroblast activity. Surface silanization with APTES covalently anchors the matrix to the chip, while Genipin crosslinking progressively increases stiffness and elasticity without harming cells. This supports >10 days of co‐culture and

Prediction Power Propulsion of the Ship at the Stage of Preliminary Design Part II: Mathematical Model Ship Power Propulsion for Service Speed Useful in the Preliminary Design

Management Systems in Production Engineering, 2017
During the design of the ship the most important decisions are made at the stage of preliminary design. One of the most important design parameters assumed by the shipowner is its service speed in real weather conditions occurring in the shipping line ...

Potato contract farming and ‘privileged spaces’: preliminary insights from rural Maharashtra

DIE ERDE: Journal of the Geographical Society of Berlin, 2014
The emergence of modern value chain schemes such as contract farming in rural India are exposing households to new forms of agricultural production. Evidently, the spread of such schemes in India will have spatial implications for rural development. This

Natural Biomaterials for Osteochondral Repair: From Source to Strategy

Advanced Healthcare Materials, EarlyView.
Biological origin‐guided overview of natural biomaterials and therapeutic strategies for osteochondral tissue engineering. The circular diagram categorizes representative materials and strategies into plant/algae‐derived, microbial‐derived, animal‐derived, and human‐derived sources, centered on an osteochondral defect repair model.

Counterintuitive Fluorescence Blue Shift in Symmetry Breaking Dicationic Bis(indolium) with Two‐Photon Absorption Properties for NIR Living Cell Imaging

Advanced Materials, EarlyView.
Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.

Enhanced Contraction and (In)dependence Preliminary report

, 2007
We introduce a number of contraction operations that allow us to preserve more information in the process of belief contraction and revision of our epistemic states. One of them, choice contraction, will be argued to characterise basic (in)dependence relations among propositions belonging to the epistemic state.

The Legal Effect of the Preliminary Contract

Scientific Journal Of Humanities and Social Sciences
The legal effect of the preliminary contract should be based on the theory of contracting. Comparing to the theory of negotiation and the theory of content determination, the theory of contracting is more appropriate in terms of respecting for parties’ autonomy and meeting the purpose of concluding the preliminary contract.

Stable Protein‐Based G‐Quadruplex‐Derived Supramolecular Bioinks as Tunable ECM‐Mimetic Constructs Assembled by Combining Non‐Covalent and Covalent Strategies

Advanced Materials, EarlyView.
Harnessing the synergistic interplay of supramolecular self‐assembly, under macromolecular crowding conditions, and enzymatic‐mediated covalent crosslinking toward a stable protein‐based G‐quadruplex‐derived supramolecular bioink. This bioinspired strategy enables the biofabrication of complex and tunable ECM‐mimetic constructs, providing a platform ...
