Characterization of a Recyclate‐Based MgO‐Steel Composite As‐Sintered Inert Anode Candidate After Exposure to Cryolite Electrolysis

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...

On‐Demand Activation of Thin Alginate Shell Encapsulated Volatile Liquid for Untethered Pneumatic Soft Actuation

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐changing liquids enable untethered pneumatic actuation in soft robotics but suffer from volatility and storage challenges. This work reports a simple method to encapsulate Novec 7000 within micron‐thin alginate shells via in situ injection and ionic crosslinking.

High magnification self-imaging

Applied Optics, 1982
Strongly magnified images of a periodic object can be obtained by using the Talbot effect. Two particular advantages are simplicity and compactness of the setup even for a high magnification ratio. First we recall the principle of self-imaging and the basic results derived by Rayleigh.

Electromagnetically induced self-imaging

Optics Letters, 2007
We study the self-imaging and image-transforming properties of a probe field in a cold atomic medium with electromagnetically induced transparency (EIT). Due to the similarities between the gradient-index medium and the inhomogeneous index distribution of an EIT medium under the conditions of a negative probe detuning and a Gaussian control field, we ...

Self-Image of Nurses

Psychological Reports, 1976
163 female graduate nurses described themselves using Gough and Heilbrun's Adjective Check List. The nurses scored higher on Dominance, Self-control, Achievement, Order, Self-confidence, Counseling, Readiness and Nurturance, among other variables and lower on Succorance, Change, Abasement, Lability and Number of Unfavorable Items Checked than the ...

Self-Image of Social Workers

Psychological Reports, 1976
105 female social workers described themselves using Gough and Heilbrun's Adjective Check List. They scored higher on Achievement, Endurance, Dominance, Self-control, Order, Self-confidence, Defensiveness, Personal Adjustment, and Aggression among other variables and lower on Number of Unfavorable Adjectives Checked, Affiliation, and Succorance than ...

Differentiation of Adolescent Self-Images

Archives of General Psychiatry, 1973
Multiple self-images held by 58 adolescents were studied using a specially developed Q-sort technique. A perceptual-cognitive process, psychological differentiation, was also followed. Results suggest that "realms" of self-image are selectively influenced by psychopathology, age, and sex.
