Activation of mixed lineage kinase 3 by fine particulate matter induces skin inflammation in human keratinocytes.

Fine particulate matter (PM) induces a range of diseases, including skin disorders, through inflammatory responses. In this study, we investigated the novel mechanisms by which PM causes skin inflammation in human keratinocytes HaCaT. We observed increased protein expression of cyclooxygenase-2 (COX-2) and the production of prostaglandin E2 (PGE2) in PM-treated HaCaT cells.

A Post-Treatment Method to Enhance the Property of Aerosol Jet Printed Electric Circuit on 3D Printed Substrate.

Aerosol jet printing of electronic devices is increasingly attracting interest in recent years. However, low capability and high resistance are still limitations of the printed electronic devices. In this paper, we introduce a novel post-treatment method to achieve a high-performance electric circuit.

Nanoscale-Dewetting-Based Direct Interconnection of Microelectronics for a Deterministic Assembly of Transfer Printing.

As electronics dramatically advance, their components should be fabricated for miniaturized scale, and integrated on limited-size substrates with extremely high density. Current technologies for the integration and interconnection of electronics show some critical limitations in the application of microscale electronics. To address these problems, herein, a new direct and vertical interconnection driven by selective dewetting of a polymer adhesive is introduced.

Laser-Induced Graphene on Additive Manufacturing Parts.

Additive manufacturing (AM) has become more prominent in leading industries. Recently, there have been intense efforts to achieve a fully functional 3D structural electronic device by integrating conductive structures into AM parts. Here, we introduce a simple approach to creating a conductive layer on a polymer AM part by CO₂ laser processing.
