Dual‐Mode Magnetic Elastomer for On‐Demand Motion and Degradation

open access: yesAdvanced Functional Materials, EarlyView.
A dual‐mode magnetic elastomer is introduced, enabling DC field‐driven programmable actuation and AC field‐driven magnetothermal degradation. GHz‐range magnetic fields generate ultrafast heating of magnetic nanoparticles that activates cleavage of the silicone elastomer matrix.

Fire Resistance of Composite Beams with Restrained Superposed Slabs

open access: yesAdvances in Materials Science and Engineering, 2020
To investigate the fire resistance of composite beams with restrained superposed slabs, three specimens were tested under uniformly distributed loads in a furnace. The effects of the thickness of the postcast top layer in superposed slabs and the spacing

Effective Width of Floor Systems for Application in Seismic Analysis [PDF]

open access: yes, 1980
Effective width coefficients for floor systems have been developed for use in the analysis of frames subjected to lateral seismic loads. The results cover a wide range of the governing nondimensional parameters, and are applicable to floor slabs with ...

Transmission properties of left-handed band-gap structures

open access: yes, 2004
We analyze transmission of electromagnetic waves through a periodic band-gap structure consisting of slabs of a left-handed metamaterial and air. Using the effective parameters of the metamaterial derived from its microscopic structure, we study, with ...

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

open access: yesAdvanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Opinion: Gavage Administration of MXene as a Route‐Specific Alternative to Intravenous Injection into the Bloodstream of Laboratory Animals for Reducing Systemic Nanotoxicity Risks in Immunosuppression and Post‐Transplantation Models with Bile Acid Modification

open access: yesAdvanced Healthcare Materials, EarlyView.
Recent studies reported immunosuppressive properties of specific MXene nanomaterials. Their intravenous injection into the bloodstream of laboratory animals has been a common delivery method to suppress systemic inflammation and prevent transplant rejection.
