Recent progress in tracking the viability of transplanted stem cells in vivo

The viability of the transplanted stem cells is particularly crucial in determining the success of stem cell-based regenerative medicine. Therefore, the development of non-invasive imaging methods that can in situ monitor the viability of the transplanted stem cells is urgently needed. Now, researchers in Su’zhou summarize the recent progress in tracking the viability of the transplanted stem cells in vivo, including reporter-gene based methods, exogenous contrast label-based methods and multimodel imaging methods.

Precise synthesis of discrete and dispersible carbon-protected magnetic nanoparticles for efficient MRI imaging and photothermal therapy

We have developed a new synthesis of discrete, dispersible, uniform, carbon-protected magnetic nanoparticles, which possess excellent water-dispersibility, biocompatibility, a high T2 relaxivity coefficient (384 mM–1•s–1), and a high photothermal heating effect. They can be used as multifunctional core components suited for future extended investigation in early diagnosis, detection and therapy, catalysis, separation, and magnetism.

Superior electrocatalytic activity of mesoporous Au film templated from diblock copolymer micelles

Mesoporous Au films with pore sizes up to 25 nm were successfully fabricated by using a polymeric micelle approach. A superior catalytic activity of the mesoporous Au films towards methanol oxidation was confirmed, which was related to its unique atomic structures around the mesopores.

Multilayered electret films based triboelectric nanogenerator

This paper presented a novel electret film based TENG. The performances have been increased by 7 times as compared to those subjected to contact electrification. This work has proven that the injection of charges into electret films by corona charging is a simple, effective and cost-efficient approach to enhance the surface charge density and the output performances of TENG, which is quite beneficial to the applications of TENGs.

Preparation of magnetically recoverable nanocatalyst via cobalt-doped Fe3O4 nanoparticles and its application in the hydrogenation of nitroarenes

Innovative cobalt-doped Fe3O4 nanocrystalline particles were effectively prepared via chemical coprecipitation in an aqueous solution. Co0.2Fe2.8O4 demonstrates highly efficient and recyclable properties in the hydrogenation of nitroarenes at low temperatures, in absolute water and atmospheric pressure, resulting in almost 100% yield and selectivity.

Peptide recognition by functional supramolecular nanopores with complementary size and binding sites

It remains a challenge to fabricate controllable bioactive surfaces because of the conformation diversity of biomolecules. To break through this restriction, this study developed a 'nanopore-confined recognition' strategy to manipulate the adsorption of cyclic peptide at the single-molecule level through precise design of functionalized conjugated macrocycle supramolecular nanopores with complementary architectures and binding sites.

Topologically insulating and superconducting phase in silicon thin film

First-principles calculations show that the iodized Si(111) thin film can be tuned into a topological insulator and a BCS superconductor arising from strain and carrier effects. The nontrivial band gap of topological insulator can be 0.5 eV, while the transition temperature of BCS superconductor can be 9.2 K.

Achieving excellent bandwidth absorption by a mirror growth process of magnetic porous polyhedron structures

A symmetrical Fe2O3/BaCO3 hexagonal cone structure formed was by a mirror growth process. Focused ion beam (FIB) and HRTEM techniques revealed the α-Fe2O3 possessed the single crystal feature. Ba ion contributed to symmetrical structure. Subsequently, porous magnetic symmetric hexagonal cone structures were achieved. The maximum absorption frequency bandwidth covered 7.2 GHz under coating thickness d=1.5 mm. Special structure and absence of BaCO3 probably played an vital role on the excellent electromagnetic absorption properties.

Pd-Ag alloy hollow nanostructures with interatomic charge polarization for enhanced electrocatalytic formic acid oxidation

Reducing the usage of expensive Pd and achieving high performance are ultimate goals for formic acid oxidation, an important electrocatalytic reaction for proton-exchange membrane (PEM) fuel cells. In this work, both goals are simultaneously achieved by fabricating hollow structures to increase the number of active sites as well as utilizing interatomic interactions to tune the species adsorption and activation.
