Hierarchical ZnSn(OH)6/Zn2SnO4 yolk–shell nonspherical structures that are composed of self-supported nanowire arrays have been conveniently prepared via a simple secondary growth method. The XRD and TEM results indicate that the composition of the outer nanowire shell is the Zn2SnO4 (ZTO) phase, while the inner cubic…
Dye-sensitized solar cells (DSSCs) have attracted extensive attention for serving as potential low-cost alternatives to silicon-based solar cells. As a vital role of a typical DSSC, the counter electrode (CE) is generally employed to collect electrons via the external circuit and speed up the reduction reaction of I3-…
In this work, we developed a dual-site two-photon (TP) fluorescent RSH probe ( CA-TPP ) for imaging mitochondrial RSH in living systems. In particular, probe CA-TPP was capable of using TP fluorescence to track mitochondrial RSH over a long period for the first time.
A vanadium based hydroxy-phosphate of the Tavorite-type structure LiVPO 4 OH was obtained for the first time, by a hydrothermal route. Li + and H + are extracted from the structure at the same equilibrium potential.
The development of drug delivery coating systems for local and long-term drug release is gaining increasing interest especially to functionalize bioinert implants with osseointegration and antibacterial properties. In this study, a biodegradable drug delivery coating platform consisting of drug-loaded PHBV microsphere…
Recent studies have indicated that graphene and its derivative graphene oxide (GO) engage in a wide range of antibacterial activities with limited toxicity to human cells. Here, we systematically evaluate the dependence of GO toxicity on the size of the nanoparticles used in treatments: we compare the cytotoxic effect…
Osteoporosis is a serious public health problem characterized by low bone density and deterioration of the bone microarchitecture. Current treatment options target either osteoclast resorption or osteoblast formation. It has been reported that berberine, a close structural analog of palmatine, inhibited bone loss in a…
Charge transfer and charge delocalisation processes play key roles in the functions of large biomolecular systems and organic/inorganic devices. Many of the short-lived transients involved in these processes can be sensitively detected by monitoring their low-energy electronic transitions in the near-IR region. Ultraf…
This study describes an eco-friendly synthesis for the production of zero-valent iron nanoparticles (nZVIs). Extracts of capuli (Prunus serotina) and mortino (Vaccinium floribundum) were used as reducing and stabilizer agents. Freshly prepared nanoparticles were characterized with Dynamic Light Scattering (DLS), Trans…
Many biological and technological complex fluids exhibit tight microstructural alignment that confers them nematic mechanical properties. Among these we count liquid crystals and biopolymer networks, which are often available in microscopic amounts. However, current microrheological methods cannot measure the directio…
The synthesis and exchange reaction of a rigid, isoindoline-functionalized tetraphenylmethane multi-spin system is described. The exchange reaction was followed using EPR spectroscopy.
A hybrid structure composed of CH 3 NH 3 PbBr 3 microwires and tapered fibers exhibits highly efficient light collection.
Voltammetric Observation of Transient Catalytic Behavior of SPS in Copper Electrodeposition—Its Interaction with Cuprous Ion from Comproportionation, Cho, Sung Ki, Kim, Hoe Chul, Kim, Myung Jun, Kim, Jae Jeong
Atomically detailed simulations were used to examine CO2/N2separation potential of metal organic framework- (MOF-) based mixed matrix membranes (MMMs) in this study. Gas permeability and selectivity of 700 new MMMs composed of 70 different MOFs and 10 different polymers were calculated for CO2/N2separation. This is th…
Considering that an electric-double-layer (EDL) structure may significantly impact on the mass transport and charge transfer kinetics at the interfaces of nanometer-sized electrodes, while EDL structures could be altered by the finite sizes of electrolyte and redox ions, the possible effects of ion sizes on EDL struct…
Nanosheet-assembled yolk–shell anatase TiO2 microspheres were synthesized utilizing the slow hydrolysis of K2TiO(C2O4)2 in a mixed solution of H2O2 and HNO3. Under a temperature near to the ambient one, microspheres assembled with nanoparticles were firstly obtained at the early reaction stage. Prolonging the reaction…
Well-defined polymers containing both fluorescent and protein-reactive groups at the chain end have been facilely synthesized by the one-pot combination of the four-component Ugi reaction and RAFT polymerization.
Outstanding activity of I-BiOBr/BiPO 4 was displayed due to the synergetic effects of doped I − ions in I-BiOBr and I-BiOBr/BiPO 4 interface.
The goal of this study was to investigate the effect of the Panax notoginseng ethanol extract (PNEE) on the regulation of human colorectal cancer (CRC) metastasis. The migratory, invasive, and adhesive abilities and the expression of metastasis-associated regulatory molecules in cultured human CRC cells (HCT-116) trea…
Upon salinity challenge, the Na(+)-K(+)-ATPase (NKA) of fish kidney plays a crucial role in maintaining ion and water balance. Moreover, the FXYD protein family was found to be a regulator of NKA. Our preliminary results revealed that fxyd12 was highly expressed in the kidneys of the two closely related euryhaline med…
