Multi‐Scaled Cellulosic Nanonetworks from Tunicates

Advanced Functional Materials, EarlyView.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

Economic Analysis of CO2 DEA-MDEA Removal System [PDF]

, 2012
Removal of CO2 using aqueous amine systems is one of the popular methods in treating flue gas. Aqueous amines are organic solvents that selectively remove CO2 gas from waste stream. Various types of amines are often used together in a blend of mixture to

The Role of Fluorine‐Functionalized Organic Spacers for Defect Passivation and Low‐Dimensional Phase Formation in 3D MAPI Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
Fluorine‐functionalized organic spacers (2F, 3F, 5F) are investigated to identify as optimal passivation agents for 3D MAPI perovskite solar cells (PSCs). The study highlights how altering fluorine positioning affects defect passivation, low‐dimensional phase (LDP) formation, and stability, emphasizing its role in molecular interactions and offering ...

A Koopman-based framework for forecasting the spatiotemporal evolution of chaotic dynamics with nonlinearities modeled as exogenous forcings [PDF]

arXiv, 2019
We introduce a data-driven method and shows its skills for spatiotemporal prediction of high-dimensional chaotic dynamics and turbulence. The method is based on a finite-dimensional approximation of the Koopman operator where the observables are vector-valued and delay-embedded, and the nonlinearities are treated as external forcings.

Quark matter as dark matter in modeling galactic halo [PDF]

, 2012
Considering the flat rotation curves as input and treating the matter content in the galactic halo region as quark matter, we have found out a background spacetime metric for the region of the galactic halo. We obtain fairly general conditions that ensure that gravity in the halo region is attractive.

Facile synthesis of cooperative acid-base catalysts by clicking cysteine and cysteamine on an ethylene-bridged periodic mesoporous organosilica [PDF]

, 2016
A periodic mesoporous organosilica (PMO) that contains ethylene bridges was functionalized to obtain a series of cooperative acid-base catalysts. A straightforward, single-step procedure was devised to immobilize cysteine and cysteamine on the support ...

Optimizing Angiopep‐2 Density on Polymeric Nanoparticles for Enhanced Blood–Brain Barrier Penetration and Glioblastoma Targeting: Insights From In Vitro and In Vivo Experiments

Advanced Functional Materials, EarlyView.
The Angiopep‐2 peptide density on polymeric nanoparticles significantly impacts blood–brain barrier (BBB) penetration. This study explores this nuanced relationship using various in vitro models and in vivo assays, revealing that dynamic models better predict BBB penetration.
