Microgravity Polymers [PDF]

open access: yes
A one-day, interactive workshop considering the effects of gravity on polymer materials science was held in Cleveland, Ohio, on May 9, 1985. Selected programmatic and technical issues were reviewed to introduce the field to workshop participants ...

Herbal Formula Yi‐Fei‐Jie‐Du‐Tang Regulates Epithelial‐Mesenchymal Transition and Vasculogenic Mimicry in Lung Cancer via HIF1A‐Mediated Ferroptosis

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Yi‐Fei‐Jie‐Du‐Tang (YFJDT), a traditional Chinese medicine, has shown potential in lung cancer treatment by targeting key pathways. This study explores the mechanisms of YFJDT using bioinformatics, xenograft models, and A549 cells, demonstrating that YFJDT downregulates HIF1A, promotes ferroptosis, and inhibits epithelial‐mesenchymal transition (EMT ...

A thermostable trilayer resist for niobium lift-off

open access: yes, 1999
We have developped a novel lift-off process for fabrication of high quality superconducting submicron niobium structures. The process makes use of a thermostable polymer with a high transition temperature T_{g}= 235 C and an excellent chemical stability.

A review on the progress of polymer nanostructures with modulated morphologies and properties, using nonporous AAO templates [PDF]

open access: yesarXiv, 2017
Polymers with the same chemical composition can provide different properties by reducing the dimension or simply by altering their nanostructure. Recent literature works report hundreds of examples of advances methods in the fabrication of polymer nanostructures accomplished following different approaches, soft lithography, self-assembly routes ...

Thermal conductivity of polymers and polymer nanocomposites [PDF]

open access: yesarXiv, 2018
Polymers are widely used in industry and in our daily life because of their diverse functionality, light weight, low cost and excellent chemical stability. However, on some applications such as heat exchangers and electronic packaging, the low thermal conductivity of polymers is one of the major technological barriers.

Ground state properties of ferromagnetic metal/conjugated polymer interfaces [PDF]

open access: yes, 2002
We theoretically investigate the ground state properties of ferromagnetic metal/conjugated polymer interfaces. The work is partially motivated by recent experiments in which injection of spin polarized electrons from ferromagnetic contacts into thin films of conjugated polymers was reported.
