    Boron-doped carbon nanotube (CNT) 3D sponges are compared with the undoped CNT sponges in terms of the plastic, elastic, viscoelastic, and dynamic viscoelastic mechanical properties. The boron-doped CNT sponge shows more predictable and stable mechanical properties than the undoped sponge. The superior properties of boron-doped CNT sponges are related to the “elbow-like” junctions on the doped carbon nanotubes.

    Polymer multilayer capsules are used by P. Rivera_Gil, W. J. Parak, and co-workers for concomitant pH-sensing and enzyme delivery to lysosomes in the framework of enzyme-replacement therapy in lysosomal-storage disorders, as described on page 991. The capsules act as local reporters of the pH by changing the fluorescence of the carried sensor from red (alkaline) to yellow (acidic) upon endocytosis and organelle acidification. In the acidic lysosomes, the capsules deliver the enzyme to substitute the defective one.

  5. Ultrasensitive PbS-Quantum-Dot Photodetectors for Visible–Near-Infrared Light Through Surface Atomic-Ligand Exchange

    Photodetectors based on PbS quantum dots are first constructed by using an atomic-ligand exchange method. They yield high device performances, i.e., responsivity up to 7.5 × 103 A W−1, relatively fast response time/recovery time of ≈4/40 μs and higher stability to 100 kHz pulsed light.
