A new theranostic platform is developed based on biocompatible polyacrylic acid (PAA)-Co9Se8 nanoplates. PAA-Co9Se8 nanoplates are successfully utilized for photoacoustic imaging (PAI)/MRI dual-modal imaging. Moreover, the PAA-Co9Se8-DOX showed pH-responsive chemotherapy and enabled the combination of photothermal therapy and chemotherapy to receive superior antitumor efficacy. This work promises further exploration of the 2D nanoplatforms for theranostic applications.
- Microfluidic Printheads for Multimaterial 3D Printing of Viscoelastic Inks

Article first published online: 17 APR 2015 | DOI: 10.1002/adma.201500222
Multimaterial 3D printing using microfluidic printheads specifically designed for seamless switching between two viscoelastic materials “on-the-fly” during fabrication is demonstrated. This approach opens new avenues for digital assembly of functional matter with controlled compositional and property gradients at the microscale.
- From “Smaller is Stronger” to “Size-Independent Strength Plateau”: Towards Measuring the Ideal Strength of Iron

The trend from “smaller is stronger” to “size-independent strength plateau” is observed in the compression of spherical iron nanoparticles. When the diameter of iron nanospheres is less than a critical value, the maximum contact pressure saturates at 10.7 GPa, corresponds to a local shear stress of ≈9.4 GPa, which is comparable to the theoretical shear strength of iron.
- Highly Transparent and Stretchable Field-Effect Transistor Sensors Using Graphene-Nanowire Hybrid Nanostructures

Transparent and stretchable electronics with remarkable bendability, conformability, and lightness are the key attributes for sensing or wearable devices. Transparent and stretchable field-effect transistor sensor using graphene-metal nanowire hybrid nanostructures have high mobility (≈3000 cm2 V−1 s−1) with low contact resistance, and they are transferrable onto a variety of substrates. The integration of these sensors for RLC circuits enables for wireless monitoring.
- Direct Observation of Reversible Magnesium Ion Intercalation into a Spinel Oxide Host
Chunjoong Kim, Patrick J. Phillips, Baris Key, Tanghong Yi, Dennis Nordlund, Young-Sang Yu, Ryan D. Bayliss, Sang-Don Han, Meinan He, Zhengcheng Zhang, Anthony K. Burrell, Robert F. Klie and Jordi Cabana

Direct evidence of Mg2+ intercalation into a spinel-type Mn2O4 is provided. By combining tools with different sensitivities, from atomic resolution X-ray spectroscopy to bulk X-ray diffraction, it is demonstrated that Mg2+ reversibly occupies the tetrahedral sites of the spinel structure through the reduction of Mn when the electrochemical reaction is performed.
