Hollow microspheres of two bismuth oxychlorides, BiOCl and Bi24O31Cl10, with high visible light photocatalytic activity were selectively synthesized. The Bi24O31Cl10 hollow microsphere showed the highest catalytic activity because of the ideal combination of its suitable band structure and stable hollow nanostructure.

Spin injection into self-organized InAs/GaAs quantum-dot molecular structures (QMSs) is shown to originate from barrier layer regions immediately surrounding the QMSs that exhibit local potentials, which significantly deviate from the commonly believed 2D/3D nature of the wetting layer/GaAs barrier layer and lead to severe spin loss. QMSs with a high symmetry of a lateral arrangement are identified as the optimal structure for both spin detection and spin injection.

First-principle calculations indicate that the Th@Au14 cluster adopts a closed-shell superatomic 18-electron configuration comprising the 1S21P61D10 Jellium state. The superatomic orbitals involved in the excitations can induce a strong CT-SERS enhancement of ~104.

Highly uniform 3-D urchin-like W18O49 nanoarchitectures (U-WO), consisting of 1-D single-crystalline W18O49 nanowires with unique morphological and structural features, are demonstrated to be excellent supercapacitor electrode materials. The U-WO electrodes exhibit both high-rate capability as well as enhanced long-life cycle performance, as exemplified by a specific capacitance of ~176 F·g–1 even at an extremely high current density of 40 A·g–1 for up to 7,000 cycles.

The paper reports on a relevant example of a multifunctional nanomaterial that is able to synergically combine the high photoactivity and magnetic characteristics of binary nanocrystals (BNCs) composed of a photoactive TiO2 nanorod joined to a superparamagnetic γ-Fe2O3 spherical domain, with the molecular recognition properties of a peptide containing an RGD motif that targets the αvβ3 integrin receptor expressed on activated endothelial cells and several types of cancer cells. The prepared peptide/BNC conjugated nanomaterial has potential in theranostic applications, including targeted imaging and treatment of cancer.

Self-assembling peptides that form tissue specific hydrogel are further engineered with positively charged lysine groups to electrostatically immobilize viral vectors to provide localized delivery. Analysis in vivo confirms the highly localized delivery.

In this paper we describe how the unique properties of graphene can be exploited to control the properties of surface acoustic waves. In particular we demonstrate the ability to significantly change the wave velocity by applying a bias voltage to a hybrid graphene/lithium niobate device.
