Large single crystals of lanthanide-doped LiYF4 are well-known solid-state laser materials. A new method to grow a shell of LiYF4 allows the synthesis of ~ 40 nm LiYF4:Yb/LiYF4 and LiYF4:Yb,Er/ LiYF4 core/shell nanocrystals with luminescence decay times of the Yb3+ and Er3+ ions similar to those of the corresponding laser crystals. Core/shell particles doped with 18% Yb3+ and 2% Er3+ display upconversion luminescence (UCL) with an excitation power density (P)-dependent quantum yield of up to 1.25% at P of 180 W·cm−2.

Selective conversion of CO2 can be enabled by periodicities in the Au8n + 4(TBBT)4n + 8 (n = 3–6, TBBT = 4-tert-butyl-benzenethiolate) nanoclusters: Methanol, formic acid, ethanol, and ethanol can be respectively obtained on the Au28(TBBT)20, Au36(TBBT)24, Au44(TBBT)28, and Au52(TBBT)32.

Four LiV3O8 (LVO) nanosheets with different V4+ and oxygen vacancy contents and positions were synthesized. Based on the analysis of the effects of V4+ and oxygen vacancies on the electrochemical properties of LVO, the reasons why oxygen-deficient LVO nanosheets as cathode material of lithium ion batteries have high stability and rate capability were proposed.

We investigate the heat dissipation characteristics of graphene foam devices. While their convective areas are comparable to that of bulk materials, their coefficient of convection is several orders of magnitude higher than that of metals. In addition, due to negligible temperature-induced morphological changes, these devices exhibited reproducible thermal behavior.

We present in this manuscript a quantitative description of what we call “nanoscaled Vasarely surfaces” appearing after self-ordering of sapphire vicinal surfaces. Such two-dimensional (2D)-periodic surface organizations are obtained through a very simple way.

A self-targeting hyaluronate nanogel (CDDPHANG/DOX) is developed to reverse drug resistance through the synchronizing pharmacokinetics, enhancing intratumoral accumulation, and intracellular release of topoisomerase II inhibitor doxorubicin (DOX) and DNA-crosslinking agent cisplatin (CDDP), which demonstrates improved antitumor efficacy towards drug-resistant MCF-7/ADR breast cancer along with the visualization of fluorescence imaging of DOX and micro-computed tomography (micro-CT) imaging of CDDP.
