Hierarchical Porous Monoliths of Steel with Self‐Reinforcing Adaptive Properties

Porous steel structures combining ultralow weight and high mechanical efficiency are manufactured by printing, reducing, and sintering wet foams containing iron oxide precursor particles. By forming new load-bearing struts when compressed, the porous structures are able to reversibly stiffen in response to nonuniform stresses, a behavior that conceptually...

A Dual‐Locked Tandem Fluorescent Probe for Imaging of Pyroptosis in Cancer Chemo‐Immunotherapy

A dual-locked and tandem activatable probe (DTAP) is presented for real-time near-infrared fluorescence (NIRF) imaging of intratumoral pyroptosis during cancer chemo-immunotherapy in living mice. It provides a non-invasive tool to study the regulatory mechanism of pyroptosis during cancer therapy and predict cancer therapeutic efficacy, hence capable...

Understanding Self‐Assembly of Silica‐Precipitating Peptides to Control Silica Particle Morphology

Biomimetic silaffin-based peptides give rise to different template structures depending on stereochemistry and connectivity of the central residue. NMR experiments help to decipher the peptidic template structures. The resulting structure–activity relationship provides a key to rationally control the assembly of such peptides and thereby the resulting...

Recent Progress in Strain Engineering on Van der Waals 2D Materials: Tunable Electrical, Electrochemical, Magnetic, and Optical Properties

Recently reported new methods to induce strain are summarized and discussed, and the latest developments on the modification of electrical, magnetic, and optical properties of 2D materials are updated by strain engineering (in particular properties such as the electrochemical, magnetic and superconducting characteristics, and their strain tuning have...

Intracellular Glucose‐Depriving Polymer Micelles for Antiglycolytic Cancer Treatment

A glucose-responsive polymer is designed, considering the unique metabolism of cancer cells. The polymer exhibits micellar-structure stability during blood circulation and accumulates in tumor tissues. Specific binding between the polymer and intracellular glucose induces glucose deprivation in tumor cells. Glucose metabolism is particularly inhibited;...

3D Printing of Self‐Assembling Nanofibrous Multidomain Peptide Hydrogels

Multidomain peptides (MDPs), a class of self-assembling peptides, are used to 3D print complex, 3D structures. Multiple MDPs are demonstrated as printable, and oppositely charged MDPs are printed together into layered, porous constructs. MDPs are found to support high cell viability regardless of charge, while charge is shown to influence cellular behavior...

Picoperovskites: The Smallest Conceivable Isolated Halide Perovskite Structures Formed within Carbon Nanotubes

Halide perovskites CsPbBr3 and lead-free CsSnI3 form “picoperovskites” in 1.2–1.6 nm-diameter single-walled carbon nanotubes with cross-sectional unit-cell or sub-unit-cell dimensions. The smallest of these are bilayer inorganic polymers retaining ABX3 stoichiometry while intermediate-scale Cs3PbBr3 preserves Pb2+ by forming ordered vacancies. The largest...

Encapsulating High‐Temperature Superconducting Twisted van der Waals Heterostructures Blocks Detrimental Effects of Disorder

Abstract High-temperature cuprate superconductors (HTS)-based van der Waals (vdW) heterostructures hold high technological promise. One of the obstacles hindering the progress is the detrimental effect of disorder on the properties of the vdW devices-based Josephson junctions (JJ). Here we report the new method of fabricating twisted vdW heterostructures...

Upcycling of Waste Plastic into Hybrid Carbon Nanomaterials

Abstract Graphitic one-dimensional (1D) and hybrid nanomaterials represent a powerful solution in composite and electronic applications due to exceptional properties, but large-scale synthesis of hybrid materials has yet to be realized. Here, we report a rapid, scalable method to produce graphitic 1D materials from polymers using flash Joule heating...
