Advanced Engineering Materials, EarlyView.Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

An ultra low frequency bridge for dielectric measurements
Annual Report 1960 Conference on Electrical Insulation, 1960 In 1955 Mr. I. R. Weingarten1 presented before this conference a paper in which he described a bridge capable of measuring dielectric properties down to the very low frequency of 0.01 cps. The paper, which I am privileged to present today, summarizes the effort made in the Dielectrics Section of the National Bureau of Standards to improve and test this

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring
Advanced Engineering Materials, EarlyView.Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which
