  • In this work, the formation of DNA supramolecular hydrogels was controlled by tuning rigidity of building blocks. The strand displacement reaction was used to in situ tuning the rigidity of the molecular network of the DNA supramolecular hydrogel. Our experiments revealed that the rigidity plays an important role in the formation and mechanical properties of hydrogels.

  • Tuning of the oscillations within a single nanodevice is a vital factor for harnessing them to neuromorphic computing. Herein, tuning of the oscillation properties of spin structures within a single permalloy circular disk achieved by manipulating the dimensionality of spin structures is directly observed by the time-resolved X-ray microscopy.

  • The wafer-scale homogeneous growth of WS2xSe2(1-x) monolayer alloys with full-range composition and bandgap modulation is demonstrated using metal–organic chemical vapor deposition. In these 2D TMD alloys, the bowing effect is substantially alleviated, enabling systematic bandgap modulation with the linear relationship between optical bandgap and alloying composition.

  • We developed all-solution-processed broadband photodetectors based on the wafer-scale perovskite quantum dots (PQDs)/MoS2 through light management via the monochromatization effect of the PQDs. The rational nanohybrid-based photodetectors exhibited broadband photodetection behavior that retained high photocurrents over a wide spectral range and also show superb air stability and exceptional bending durability.

  • In this study, we prepared OKPP hydrogel constructed from, OKGM, ε-PL, and γ-PGA modified by dopamine and l-cysteine. OKPP hydrogel has the ability of injectable and self-healing through the thiol-aldehyde addition and schiff-base reactions, which can solve the problem of long time use and gel breaking. OKPP hydrogel has antioxidant properties and can scavenge free radicals. This hydrogel has good antibacterial effect on Pseudomonas aeruginosa and Staphylococcus aureus, and also has strong adhesion. In the burn wound infection model, OKPP hydrogel can promote wound healing and reduce the production of inflammatory factors. It is proved that this hydrogel has good clinical potential as a wound dressing for burn wound infection.

  • A facile chemical vapor method is developed for large-scale synthesis of CsPbX3-ZSM-5 composites. Owing to the effective confinement and encapsulation of CsPbBr3 QDs by ZSM-5, the composites possess excellent photophysical properties and ultrahigh stability. The prepared composites are applied in white light-emitting diodes (WLEDs) and multicolor-coded anti-counterfeiting inks. This technique provides the probability for commercial production of these perovskite composites with robust stability.

  • A magnetic superhydrophobic tubular actuator for water transport has been designed and successfully demonstrated. Under the control of an externally applied magnetic field, the actuator could deform correspondingly and propel the water droplet in the tube to move forward with a high speed up to 16.1 cm/s, which is the highest velocity measured for water transport in a closed actuator system. Several representative liquids (i.e., phosphate buffer solution, artificial urine, and sweat) widely used in biomedical engineering have also been achieved to transport in the tubular actuator with negligible liquid loss under an applied magnetic field.

  • A very active research area in superconductivity is the performance improvementofthe current carrying capability (Jc). Here, we show that the depairing current (Jd) can beincreased by controlling the penetration depth (λ) and coherence length (ξ) in the two most representative materials: in REBa2Cu3Oy we increased the carrier density to decrease λ and ξ, and in BaFe2(As1-xPx)2 we tuned the chemical pressure. The combination ofthese thermodynamic and flux-pinning optimization routes leads to a dramatic increase of Jc to Jc ~150 MA/cm2 at 4.2 K (32.4% of Jd) for REBa2Cu3Oy, the highest value ever reported for any superconductor.

Special issue on Hydrogels and Hydrogel-related Healing Materials

Hydrogels are of great interests from the viewpoints of their diverse applications such as disposal water adsorbent, tissue engineering, drug delivery, etc. New synthetic techniques as well as analytical methods have opened new gates to intelligent and advanced hydrogel-related materials. In combination with the broad term “healing”, the hydrogel-related materials have also been experiencing remarkable innovations. Some of the healing materials are designed for their own repair, others to assist the healing of the damaged bio-organisms. This special issue of NPG Asia Materials is focusing on the recent innovations related to hydrogels and hydrogel-related healing material, and presents state-of-the-art original articles as well as comprehensive reviews in this fast-growing field.
