Transformable liquid-metal nanomedicine
To date, numerous inorganic nanocarriers have been explored for drug delivery systems (DDSs). However, the clinical application of inorganic formulations has often been hindered by their toxicity and failure to biodegrade. We describe here a transformable liquid-metal nanomedicine, based on a core-shell nanosphere composed of a liquid-phase eutectic gallium-indium core and a thiolated polymeric...
متن کاملTransformable topological mechanical metamaterials
Mechanical metamaterials are engineered materials whose structures give them novel mechanical properties, including negative Poisson's ratios, negative compressibilities and phononic bandgaps. Of particular interest are systems near the point of mechanical instability, which recently have been shown to distribute force and motion in robust ways determined by a nontrivial topological state. Here...
متن کاملTransformable masks for colloidal nanosynthesis
Synthetic skills are the prerequisite and foundation for the modern chemical and pharmaceutical industry. The same is true for nanotechnology, whose development has been hindered by the sluggish advance of its synthetic toolbox, i.e., the emerging field of nanosynthesis. Unlike organic chemistry, where the variety of functional groups provides numerous handles for designing chemical selectivity...
متن کاملA transformable tensegrity-ring footbridge
Tensegrity structures are spatial reticulated structures composed of cables and struts. A tensioncompression equilibrium leads to lightweight systems that change shape through length changes in their members. Active members thus control several degrees of freedom simultaneously. Tensegrityring modules are transformable circuit-pattern modules. The linear combination of tensegrity rings has been...
متن کاملTransformable periodic mesoporous organosilica materials.
The synthesis of novel periodic mesoporous organosilica (PMO) materials incorporating a mixture of functional monomers (cis- and trans-stilbene-based) and structural monomers has been accomplished. EDX analysis of these materials in combination with HAADF imaging of OsO(4)-stained samples reveals a homogeneous distribution of trans-olefin within the co-condensed aromatic organosilica matrix. Oz...
