The wrinkle dynamics (such as reversibility and stability) of human skin are affected by the external stimuli, well skin's structure mechanical properties. Inspired these tunable responses, three types moisture-responsive achieved, for first time, through a single film-substrate system. These include: (1) completely reversible wrinkles formation; (2) irreversible formation I: initially formed can be permanently erased never reappear; (3) II: once form, they no longer erased. key to success...
A cellulose based conductive composite hydrogel was prepared with a non-toxic crosslinking agent for application in biomedical materials.
Abstract A versatile wrinkle‐based micropatterned system with a film‐substrate structure is proposed, which contains hydrophilic film of polyvinyl alcohol or its composite laponite and hydrophobic substrate polydimethylsiloxane carbon black. The wrinkled features high design flexibility multistimuli responsiveness, can be activated by various mechanical methods, including vertical press scratch, gentle stretch‐and‐release, bend, analogous magneto‐mechanical electro‐mechanical modes....
A 3D tubular structure fabricated from the relaxation of pre-stretched 2D precursor is used to develop various stretchable electronics.
This work elucidates a route to mesoporous magnetic materials with co-continuous morphologies from block copolymer self-assembly. The structure impacts the behavior compared non-structured chemically-identical materials.
Abstract Art and materials innovation have always been intertwined, dating back to the earliest human creations. In modern times, however, increasing specialization of science often restricts artists' access cutting‐edge materials. Here, aspects an art‐science collaboration between artist Kimsooja Wiesner Lab at Cornell University, are detailed. The project involves development a custom‐made iridescent block copolymer coating by means self‐assembly, originally applied transparent window...
Abstract Rice Husks (RHs) are one of the most abundant sources biomass in world due to rice consumption. Lignocellulose and silica two main components RHs, which allow RHs be applied different areas. can partially dissolved 1-butyl-3-methylimidazolium chloride (BMIMCl), is a simple way competing with traditional extraction methods that suffer from high chemical A lignocellulose freeze gel obtained via cyclic liquid nitrogen freeze-thaw (NFT) process. Multi-functional self-assembled aerogel...
In article number 1700828, Dianyun Zhang, Luyi Sun, and co-workers develop a series of moisture-responsive wrinkled-surface devices made using poly(vinyl alcohol)–poly(dimethylsiloxane) bilayer system. These demonstrate reversible, temporary, or permanent wrinkles as moisturized, providing route to tune the optical properties wrinkled surface for various applications, such encryption devices, anticounterfeiting tabs, water indicators.
Carbon materials have found ubiquitous use in the fields of electrochemical energy storage (EES) and conversion, due to their electrical thermal transport properties, typically high specific surface areas, low densities, stability a variety systems. As demand particular for increasingly efficient EES devices grows, three-dimensionally (3D) continuous nanostructured electrode gained interest, as they present pathway interfacial areas between electrodes while overall device has areal...
Abstract Recent advances in the photocatalytic activation of dry reforming methane (DRM: CO 2 + CH 4 → 2CO 2H ) at low temperature and ambient pressure have generated considerable interest as a promising route to convert greenhouse gases into valuable synthetic gas (syngas). While detailed studies revealed mechanisms involved DRM metal-semiconductor interfaces, less attention has been devoted how high surface area semiconductor supports may enhance such conversions. Here we structure...
Self-assembled block copolymer (BCP) thin films and their nanocomposites provide nanostructures useful in myriad applications. While conventional characterization techniques an understanding of film surface internal structures, optical super-resolution microscopy (OSRM) has recently emerged as alternative way to characterize nanoscopic polymer morphology. This work describes self-assembled poly(isoprene)-block-poly(styrene)-block-poly(N,N-dimethylaminoethyl methacrylate) (PI-b-PS-b-PDMAEMA...
Solution-based soft matter self-assembly (SA) promises unique materials properties from approaches including additive manufacturing/three-dimensional (3D) printing. We report direct ink writing derived, hierarchically porous transition metal nitride superconductors (SCs) and precursor oxides, structure-directed by Pluronics-family block copolymer (BCP) SA heat treated in various environments. SCs with periodic lattices on three length scales show record nanoconfinement-induced upper critical...
Soft-Matter Quantum Materials In article number 2203908, Ulrich Wiesner and co-workers describe the academic technological promise associated with soft-matter-directed quantum materials. This is achieved by reviewing existing studies as well providing future perspectives on various classes of materials, particular focus effects soft-matter self-assembly-directed mesoscale structure properties.
