Structure and Aggregation of a Helix-Forming Polymer [PDF]

open access: yesarXiv, 2007
We have studied the competition between helix formation and aggregation for a simple polymer model. We present simulation results for a system of two such polymers, examining the potential of mean force, the balance between inter and intramolecular interactions, and the promotion or disruption of secondary structure brought on by the proximity of the ...

Hydrogel‐Impregnated Robust Interlocking Nano Connector (HiRINC) for Noninvasive Anti‐Migration of Esophageal Stent

open access: yesAdvanced Materials, EarlyView.
The development of hydrogel‐impregnated robust interlocking nano connector (HiRINC) aims to address stent migration by improving tissue adhesion and reducing mechanical mismatch in self‐expandable metallic stents (SEMSs). The network‐like porous layer of HiRINC enhances adhesion and energy dissipation, demonstrates through ex vivo and in vivo tests ...

Parameters influencing high-efficiency transfection of bacterial artificial chromosomes into cultured mammalian cells

open access: yesBioTechniques, 2003
Although bacterial artificial chromosomes (BACs) provide a well-characterized resource for the analysis of large chromosomal domains, low transfection rates have proven a significant limitation for their use in cell culture models.

Advancements in Understanding the Physicochemical Properties of Reticular Materials: An In Situ and Operando Spectroscopic Perspective

open access: yesAdvanced Materials, EarlyView.
This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

Pioneering the Future: Principles, Advances, and Challenges in Organic Electrodes for Aqueous Ammonium‐Ion Batteries

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Leveraging the numerous advantages of ammonium‐ion (NH₄⁺)—including cost‐effectiveness, low corrosiveness, preferential orientation, and rapid diffusion kinetics—aqueous NH₄⁺ batteries (AAIBs) have gained significant attention. This review highlights and evaluates the progress of AAIBs utilizing organic electrode materials such as small molecules ...

Solvation Dynamics of CO2(g) by Monoethanolamine at the Gas–Liquid Interface: A Molecular Mechanics Approach

open access: yesMolecules, 2016
A classical force field approach was used to characterize the solvation dynamics of high-density CO2(g) by monoethanolamine (MEA) at the air–liquid interface. Intra- and intermolecular CO2 and MEA potentials were parameterized according to the energetics

Moisture‐Dependent Vibrational Dynamics and Phonon Transport in Nanocellulose Materials

open access: yesAdvanced Materials, EarlyView.
Uptake of water in cellulose play an important role in modulating the structure and phonon transport. This study reports how moisture‐dependent structural modification relates to the vibrational dynamics and phonon transport and scattering of nanocellulose using inelastic neutron scattering and wide angle X‐ray scattering.
