A first coordination [2.2.2]cryptand(K+)2FeII(TI˙-)(TI2-)2·2C6H4Cl2 (1) complex of iron(ii) containing radical anions and dianions of thioindigo (TI) was obtained. The complex has two high-spin FeII centers bound by two oxygen atoms, and the TI˙- radical anions are coordinated to each FeII. As a result, the 4-spin system consisting of TI˙- (S = 1/2)-FeII (S = 2)-FeII (S = 2)-TI˙- (S = 1/2) coupled spins is formed within a dimer with strong FeII-FeII (J = -51.1 cm-1) and weaker FeII-TI˙- interactions of (J = -35.4 cm-1).We describe the functionalisation of the previously reported uranium(iii) β-diketiminate complex (BDI)UI2(THF)2 (1) with one and two equivalents of a sterically demanding 2,6-diisopropylphenolate ligand (ODipp) leading to the formation of two heteroleptic complexes [(BDI)UI(ODipp)]2 (2) and (BDI)U(ODipp)2 (3). The latter is a rare example of a tetrahedral uranium(iii) complex, and it shows single-molecule magnet behaviour.Surface modification effects of graphite and organic solvents on Ti were investigated by thermogravimetry (TG), Raman spectroscopy, and transmission electron microscopy (TEM) observations to improve its hydrogen absorption properties. As a result, Ti ball-milled with graphite showed high reactivity and selectivity for hydrogen with high durability.A 3D-printed microfluidic fuel cell is presented. Fused deposition modeling is used to build a microchannel with a 0.015 cm2 cross-sectional area for stable colaminar flow conditions. A new 3D-Printed cell fed by glycerol displays a power density of 175 mW cm-2 at 0.9 V and 1.8 V of open-circuit voltage.Four heteroleptic Ir(iii) complexes (Ir-1-Ir-4) with varied π-conjugated diimine ligands were synthesized. Their optical properties were investigated systematically via spectroscopic methods, in order to elucidate the influence of the extended π-conjugation on the singlet and triplet states of the molecules. All these Ir(iii) complexes exhibit ligand localized 1π,π* transitions below 370 nm, and broad metal-to-ligand and ligand-to-ligand charge transfer (MLCT/LLCT) absorption bands in the visible region. Extending the π-conjugation in diimine ligands influences the electron distribution of the triplet state. The 3π,π* dominated Ir(iii) complexes (Ir-3 and Ir-4) exhibit long-lived triplet states and low phosphorescence quantum yields, compared with the charge transfer dominated Ir(iii) complexes (Ir-1 and Ir-2). Complexes Ir-3 and Ir-4 exhibit broadband transient absorption spectra from 420 to 750 nm, between which the nonlinear absorption could be observed by virtue of reverse saturable absorption. The results of nonlinear transmission measurements using 532 nm laser pulses further elucidate that selected complexes Ir-3 and Ir-4 are promising candidates for optical limiting applications.This work shows that highly uniform worm micelles formed by polymerisation induced self-assembly can be obtained via simple post-synthesis sonication. Importantly, this straightforward and versatile strategy yields exceptionally monodisperse worms with tunable aspect ratios ranging from 7.2 to 17.6 by simply changing the sonication time.We report multi-modal-control over the assembly behaviour of a first-generation molecular motor bola-amphiphile in water by light, pH and the choice of counter-ions. These findings open up opportunities for the development of materials that reconfigurate enabling complex functions in response to different stimuli.The high yielding CuI-mediated click reaction is an effective procedure for the preparation of oligoporphyrinoid conjugates. However, the CuI catalyst leads to the adventitious and usually undesirable insertion of Cu ions into any non-metalated porphyrinoid centers during reaction. Here we report a "sacrificial rotaxane" strategy for the multifunctionalization of porphyrins with free base corroles without incidental copper insertion. This strategy can be considered a general method for implementing CuI-mediated click reactions with metal cation sequestration to avoid detrimental effects caused by the presence of copper cations.We suggest epoxycyclopentane (ECP) as a novel guest compound for hydrate-based energy storage. All of the key properties of the ECP hydrate, including the thermodynamic stability, storage capacity, and formation condition, are notably superior to those of hydrates containing tetrahydrofuran (THF) and cyclopentane (CP), currently considered to be the most powerful promoters.Herein, a smart competitive-type photoelectrochemical (PEC) sensor based on an antigen-down (Ag-down) format for procalcitonin (PCT) detection is proposed.  https://www.selleckchem.com/products/buloxibutid.html  A fullerene sensitized flower-like Sn3O4 nano-structure is used as the photoactive platform, and FeS2 is labeled on the secondary antibody as a signal adjusting element. The sensor exhibits excellent sensitivity and great stability.Attenuated bacteria-mediated tumor targeting diagnosis will provide a novel strategy for further cancer treatments owing to the intrinsic facultative anaerobic characteristic of bacteria and rapid proliferation in the tumor sites. In this work, we firstly investigate the in vivo behaviour of the attenuated Salmonella typhimurium (S. typhimuriumΔppGpp/lux) after intravenous injection. S. typhimurium exhibits rapid proliferation in tumor sites after three days of injection through bioluminescence imaging, the Luria-Bertani plate and the Gram-staining assay. In contrast, S. typhimurium does not proliferate in the normal tissues and could be excreted from the body of mice. Afterwards, a targeting peptide ubiquicidin (UBI) labeled with fluorescent dye Cy5.5 or radionuclide 125I was intravenously injected into the mice with or without S. typhimurium treatments for in vivo fluorescence imaging and single-photon emission computed tomography (SPECT/CT) imaging, respectively. The results show that the peptide UBI could specifically target the two independent bacteria-infected tumor models, the 4T1 murine breast cancer model and the CT26 mouse colon cancer model, realizing the sensitive multimodal imaging of tumors. Such a strategy (bacteria-mediated tumor targeting) may further improve the sensitivity to early diagnosis of tumors. We hope that our developed strategy could further be extended to cancer theranostics in the future, bringing good news for cancer patients.
