Characterization of Nitinol Produced by Laser Powder Bed Fusion for Mechanical Metamaterial Applications

open access: yesAdvanced Engineering Materials, EarlyView.
Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Public Policy and the Economic Wellbeing of Elderly Immigrants [PDF]

open access: yes
In this paper we document the economic outcomes of elderly immigrants to Canada. Our objective is to describe the extent to which elderly immigrants may have low income (are “in povertyâ€) and their interactions with the Canadian income transfer system.

Application of Raman and Photoluminescence Spectroscopy to MgO‐C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
Visible to near infrared luminescence of MgO is studied on MgO‐C bricks and nominally pure MgO powder, with focus on two similar sharp high‐intensity signals, at 699 and 871 nm, each surrounded by symmetrical sidebands. The nature of these sidebands is investigated by temperature‐dependent spectroscopic measurements, confirming phonon involvement by ...

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

open access: yesAdvanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Co-residence with children as a mediator between widowhood and loneliness in older adults

open access: yesBMC Geriatrics
Background Loneliness in older adults, exacerbated by widowhood, is a significant public health concern. While widowhood can lead to changes in living arrangements, its impact on loneliness may vary across cultural contexts.

Boomerang kids: labor market dynamics and moving back home [PDF]

open access: yes
This paper examines the relationship between the dynamics of parent-youth living arrangements and labor market outcomes for youths who do not go to college in the United States. The data come from a newly constructed panel data set based on retrospective

Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

open access: yesAdvanced Engineering Materials, EarlyView.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.
