Photothermally Powered 3D Microgels Mechanically Regulate Mesenchymal Stem Cells Under Anisotropic Force

open access: yesAdvanced Materials, EarlyView.
The photothermally powered microgel is designed to mechanically train mesenchymal stem cells using spatially patterned exogenous forces in three‐dimensional (3D) workspaces. When microgels are activated selectively via photothermal actuation, locally confined tens of nN forces are exerted on cells, triggering osteogenic differentiation in encapsulated ...

The resilience of post market infrastructures and payment systems Initiatives and perspectives. [PDF]

open access: yes
The use of non-cash payment schemes is particularly widespread in France where the number of non-cash transactions is in fact well above the European average. Though they have different features corresponding to users’ varying needs (payments may be face-

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

open access: yesAdvanced Materials, EarlyView.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

The Presumption of Payment

open access: yes, 2014
At Gettysburg College, students invest a considerable amount of money to make their experiences rewarding for future aspirations. Enrollment at this school, like others, I am sure, seems to breed a special type of student: the students who view ...

Zinc‐Coordinated Trienzyme Nanogel Cascade Therapy for Accelerated Post‐Pancreatectomy Cutaneous Wound Healing

open access: yesAdvanced Materials, EarlyView.
A zinc‐coordinated nanogel assembly is reported that co‐delivers three enzymes to regulate glucose, oxidative stress, and oxygen levels. This system mimics natural enzyme cascades to reprogram the wound environment after pancreatectomy. In a post‐pancreatectomy mouse model, it accelerates healing by reducing infection, promoting blood vessel growth ...
