Advanced Engineering Materials, EarlyView.This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Advanced Engineering Materials, EarlyView.Additive manufacturing technologies like laser powder‐bed fusion offer great design freedom and individualization of products down to a batch size of one. However, parts fabricated with this technology suffer from poor quality. Acoustic assistance during the build process can minimize these drawbacks.

Advanced Engineering Materials, EarlyView.Prestraining the substrate influences coating formation process. Higher prestraining force leads to higher coating thickness and lower hardness. Increase in prestraining force enhances preliminary damage in hard anodic coating. Fatigue damage mechanisms change for hard anodized prestrained samples.

Blur point versus indistinguishable point in assessment of accommodation: objective and subjective findings in early presbyopes [PDF]
, 2003 Aim: To measure the distance from the eye and the refraction of the eye at the point at which print blurs and the point at which it becomes unreadable. Methods: Subjective accommodation in 7 early presbyopic subjects (mean age 45 years), with no

Advanced Engineering Materials, EarlyView.This study uses real‐time laser diffraction image analysis to quantify fiber diameter changes and whipping behavior from the nozzle to the collector under varying electric field conditions. By capturing diffraction (scattering) intensity changes and bending angles, melt jet and whipping behavior are accurately assessed, supporting melt electrospinning ...

African Vision and Eye Health, 2019 Background: Guidelines for predicting the amplitude of accommodation (AA) sometimes are based on measurements for the subjective push-up-to-blur method. However, the push-up-to-blur method often overestimates the accommodative response.

Mesoporous Silica Microspheres by Super‐Fast Alkaline Etching of Micrometer‐Sized Stöber Particles
Advanced Engineering Materials, EarlyView.Microscale silica particles are prepared along with a modified, scalable Stöber synthesis using the continuous addition of tetraethoxy silane to an ethanolic solution of ammonia with KCl. Etching with hydroxide ions at 95 °C gave porous analogs within minutes. Monodisperse particles are isolable in high yield after precipitation in ethanol.

Vision and Reading Difficulties Part 4: Coloured filters - how do they work? [PDF]
, 2009 This article is the fourth in a series of five about vision and reading difficulties. The first article provided a general overview and the second covered conventional optometric correlates of reading difficulties (e.g. binocular vision problems).
