Substrate Engineering for Durable Omniphobic Liquid‐Like Surfaces

open access: yesAdvanced Functional Materials, EarlyView.
The significant yet less investigated role of substrates in determining the liquid‐repellency and mechanical durability of liquid‐like surfaces (LLSs) is explored. Thick and crack‐free sol–gel silica intermediary layers are developed that can smoothen substrate asperity roughness even at the micron scale, enabling omniphobic polydimethylsiloxane‐based ...

Prospects of Electric Field Control in Perpendicular Magnetic Tunnel Junctions and Emerging 2D Spintronics for Ultralow Energy Memory and Logic Devices

open access: yesAdvanced Functional Materials, EarlyView.
Electric control of magnetic tunnel junctions offers a path to drastically reduce the energy requirements of the device. Electric field control of magnetization can be realized in a multitude of ways. These mechanisms can be integrated into existing spintronic devices to further reduce the operational energy.

Transducer Materials Mediated Deep Brain Stimulation in Neurological Disorders

open access: yesAdvanced Functional Materials, EarlyView.
This review discusses advanced transducer materials for improving deep brain stimulation (DBS) in neurological disorders. These materials respond to light, ultrasound, or magnetic fields, enabling precise, less invasive neuromodulation. Their stimulus‐responsive properties enhance neural control and adaptive therapy, paving the way for next‐generation ...

Stress as a social problem.

American Journal of Orthopsychiatry, 1964
This article attempts to penetrate the difficult problem of children with severe character disorders who show what appears to be an acquired immunity to stress. It discusses how the staff of a residential treatment center tries to work with these children. A hypothesis of treatment is posed that needs further study and experimentation.

Ageing and social problems

1981
The study of ageing and problems associated with it are now recognized as important. This is not surprising, for older people have become the major clients of the health and social services. They also have a lot of free time at their disposal. If there is to be an expansion in adult education and opportunities for creative leisure activities, the ...

Social Character and Social Problems

Social Problems, 1955
is in process of change in response to the changing social situation of this class. The latter is losing the crusading spirit that formerly encouraged its members to study social problems. Inasmuch as the sociologist has been recruited largely from this class, the ideology of this class has been reflected in the professional interests of sociologists ...
