Near‐Field Electrospinning Micro‐Printhead Achieves Precise Control of Nanofiber Deposition

open access: yesAdvanced Engineering Materials, EarlyView.
A micro‐printhead for near‐field electrospinning enables reproducible deposition of polymer nanofibers with diameters below 50 nm. Systematic parameter studies uncover the mechanisms linking operating conditions to fiber morphology, paving the way for precise and low‐cost nanoscale 3D manufacturing.As a high‐resolution, cost‐effective, and rapid ...

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Revisiting Informality: Evidence from Employment Characteristics and Job Satisfaction in Chile [PDF]

open access: yes
We use data from a unique, nationally representative survey to investigate the relationship between job satisfaction and employment characteristics in Chile. Consistent with the dualistic models, job protection appears to be a positive determinant of job

Returns to education and experience in self-employment: Evidence from Germany [PDF]

open access: yes
This paper compares the returns to human capital in the self-employed and wage-employed sectors of the economy. Using data from the former West German sample of the German Socioeconomic Panel survey for the 1984-1997 time period, we estimate returns to ...
