Double Cross‐Linked Hydrogel for Intra‐articular Injection as Modality for Macrophages Metabolic Reprogramming and Therapy of Rheumatoid Arthritis

open access: yesAdvanced Functional Materials, EarlyView.
A hydrogel for intra‐articular injection for the treatment of rheumatoid arthritis (RA) is formulated and comprehensively studied. After administration, the hydrogel induces a metabolic reprogramming of immunometabolism of macrophages to trigger fatty acid oxidation subsequently inducing polarization of anti‐inflammatory M2 macrophages. This results in

Freedom of Expression in Wartime

open access: yesUniversity of Pennsylvania Law Review, 1968
War and preparation for war create serious strains on a system of freedom of expression. Emotions run high, lowering the degree of rationality which is required to make such a system viable. It becomes more difficult to hold the rough give-and-take of controlled controversy within constructive bounds.

Morphogenic Growth 3D Printing

open access: yesAdvanced Materials, EarlyView.
I additive manufacturing process exploits the spatial propagation of a polymerization reaction front to produce 3D polymer parts 10× faster and 1000× more energy efficient than the fastest stereolithography. In contrast with existing 3D printing, this morphogenic process is inspired by biological “growth and form” due to the self‐directed propagation ...
