The kinetics of several fast heterogeneous electron-transfer reactions were investigated by steady-state voltammetry at nanoelectrodes and scanning electrochemical microscopy (SECM). disk-type, polished Pt (3.7-400-nm radius) characterized a combination voltammetry, electron microscopy, SECM. A number experimental curves obtained the same nanoelectrode to attain accuracy reproducibility similar those reported previously for micrometer-sized probes. new analytical approximation was developed...
There is a significant current interest in development of new techniques for direct characterization the intracellular redox state and high-resolution imaging living cells. We used nanometer-sized amperometric probes combination with scanning electrochemical microscope (SECM) to carry out spatially resolved experiments cultured human breast With tip radius approximately 1,000 times smaller than that cell, an probe can penetrate cell travel inside it without apparent damage membrane. The data...
Electrochemical experiments were carried out in a nanometer-sized cylindrical thin layer cell (TLC) formed by etching the surface of disk-type platinum nanoelectrode (5- to 150-nm radius). Using high frequency ac voltage, such an electrode was etched remove very (> or = 1-nm-thick) Pt. The resulting zeptoliter-scale cavity inside glass sheath filled with aqueous solution containing redox species, and immersed dry (no external solution) pool mercury produce TLC. Several approaches based on...
Exposure to mercury ions, even at very low levels, is known cause a wide variety of diseases in the brain, kidney, and central nervous system, which an increasing serious problem for human beings environment. Accordingly, great efforts have been devoted development colorimetric sensors, can selectively conveniently detect Hg2+. In this feature article, present readers better understanding specific methods their mechanisms, we will highlight sensors according receptors into several...
In this study, a novel magnetic biochar-MnFe2O4 nanocomposite (BC/FM) was prepared using low-cost corn straw and MnFe2O4 by sol-gel/pyrolyzing route egg white, which has abundant functional groups (-NH2 -COOH). Following that, its composition, morphology structure characterized various techniques including SEM-EDX, BET, XRD, VSM. Batch experiment of the adsorption for Pb(ii) Cd(ii) influence pH, kinetics, isotherm thermodynamics also studied. The results demonstrated that biochar could...
The disk-type, polished Au nanoelectrodes were prepared, characterized, and used as tips in the scanning electrochemical microscope (SECM). Kinetic parameters measured for several rapid heterogeneous electron transfer (ET) reactions compared to those obtained previously at Pt nanoelectrodes. kinetics of most investigated ET processes found be independent electrode material. In contrast reported results, rate constant hexaammineruthenium(III) reduction was somewhat higher than electrodes...
Abstract Catalyst deactivation caused by the aggregation of active metal species in reaction process poses great challenges for practical applications supported catalysts solid-liquid catalysis. Herein, we develop a hypercrosslinked polymer integrated with N-heterocyclic carbene (NHC) as bifunctional support to stabilize palladium heterogeneous C-C bond formations. This catalyst exhibits excellent stability one-pot fluorocarbonylation indoles four kinds valuable indole-derived carbonyl...
Magnetic resonance angiography (MRA) contrast agents are extensively utilized in clinical practice due to their capability of improving the image resolution and sensitivity. However, clinically approved MRA have disadvantages a limited acquisition time window high dose administration for effective imaging. Herein, albumin-coated gadolinium-based nanoparticles (BSA-Gd) were meticulously developed vivo ultrahigh-resolution MRA. Compared Gd-DTPA, BSA-Gd exhibits significantly higher...
A powerful ring-closure method was developed for the formation of cyclic polymers by combining reversible addition–fragmentation chain transfer polymerization (RAFT) and light-induced Diels–Alder click reaction. The outstanding features this novel were demonstrated from following four aspects. This convenient efficient technique could produce in air at room temperature without any other catalyst or stimulus requirements than a mild UV irradiation. universality successfully producing five...
Human Y-box binding protein 1 (YB-1) is a multifunctional and overexpressed in many types of cancer. It specifically recognizes DNA/RNA through cold shock domain (CSD) regulates nucleic acid metabolism. The C-terminal extension CSD the phosphorylation S102 are indispensable for YB-1 function. Until now, roles gene transcription translation still largely unknown. Here, we solved structure human with sequence (CSDex). reveals that interacts several residues conventional adopts rigid instead...
Cadmium (Cd2+) and mercury ions (Hg2+) are essential for the quality control of food samples because their serious toxicity to human health, but effective simple strategy parallel detection remains challenging. In this paper, a rapid method Cd2+ Hg2+ was developed using carbon dots (CDs) as fluorescent sensors. A one-step hydrothermal with single precursor l-arginine both nitrogen sources employed prepare nitrogen-doped CDs (N-CDs). N-CDs exhibited uniform particle size...
Background and purpose Executive function impairment, a slight but noticeable cognitive deficit in mild impairment (MCI) patients, is influenced by gamma-aminobutyric acid (GABA) levels. Reduced accompanied thinning of the cerebral cortex, which has higher GABA levels than white matter. However, relationships among levels, cortical thickness, executive MCI patients have not yet been elucidated. We investigated patients. Methods In this study, total 36 sex-, age-, education-matched healthy...
In hypertrophic cardiomyopathy, myocardial microstructural alterations could be detected by in vivo cardiac diffusion-tensor imaging even before the appearance of MRI findings hypertrophy or fibrosis.
Olefin hydroformylation is one of the most important industrial processes for aldehyde synthesis. Heterogeneous catalysts are easy to separate compared with homogenous catalysts, yet limited success in activity and regioselectivity control. In present work, a zeolite-encapsulated rhodium carbide species (RhCx@S-1) catalyst was developed, demonstrating not only relatively high catalytic but also good stability heterogeneous propylene hydroformylation. The unique microenvironment formed situ...
