A Close Look at the Local Structure of Functional Polymers: The Example of Poly(Vinylidene Fluoride)

open access: yesAdvanced Functional Materials, EarlyView.
To accurately develop structure‐property relationships in functional macromolecules, it is increasingly important to consider the local chain arrangement in addition to long‐range order. It is demonstrated in the case of poly(vinylidene fluoride) that solid‐state nuclear magnetic resonance (NMR) spectroscopy can provide detailed insights into the local

Investigation of the Mechanical and Electrical Properties of Elastic Textile/Polymer Composites for Stretchable Electronics at Quasi-Static or Cyclic Mechanical Loads [PDF]

open access: yes, 2019
In the last decade, interest in stretchable electronic systems that can be bent or shaped three-dimensionally has increased. The application of these systems is that they differentiate between two states and derive there from the requirements for the ...

Polar Pore Surface of Polyamide Membranes Enabling Efficient Solvent Mixture Separation

open access: yesAdvanced Functional Materials, EarlyView.
A polyamide membrane with polar pore surfaces and relatively large pore is fabricated through interfacial polymerization between polyethyleneimine and trimesoyl chloride. Rapid separation of solvents with polarity differences is achieved by the synergistic effects of pore polarity and size sieving.

Experimental study on properties of mechanical resistance of polyamide in clay soil

open access: yesIteckne, 2021
The presence of clay soil causes problems at the base of the structure: it swells when wet and shrinks when dry, which provides a reduction in the resistance to cutting of the soil.

Development of electrospun photocatalytic TiO2-polyamide-12 nanocomposites [PDF]

open access: yesMaterials Chemistry and Physics, 2015
Abstract Titanium dioxide (TiO 2 ) in different forms such as films, fibers or particles are being extensively studied for removal of contaminants from aquatic environments due to its outstanding photocatalytic activity. This work reports the development of TiO 2 -polyamide 12 electrospun fiber mats. A systematic study on the influence of electrospun

Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

open access: yesAdvanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Allosteric modulation of DNA by small molecules [PDF]

open access: yes, 2009
Many human diseases are caused by dysregulated gene expression. The oversupply of transcription factors may be required for the growth and metastatic behavior of human cancers.

Crystallization Kinetics of Polyamide 12 during Selective Laser Sintering [PDF]

open access: yesPolymers, 2018
Selective laser sintering (SLS) of thermoplastic materials is an additive manufacturing process that overcomes the boundary between prototype construction and functional components. This technique also meets the requirements of traditional and established production processes.
