Octahedral,cuboctahedral,branched and ‘rice-like’Pt NPs were synthesised using a seed-mediated growth route. Pt NPs (3 nm) were prepared and dispersed in oleyl amine to form a seed solution and then Pt(acac)2 was added. By adjusting the molar ratio of Pt from Pt(acac)2 and seed NPs, the seed diameter and the addition route of Pt(acac)2, the NPs growth could be controlled to fall into in a kinet...
The prognosis of metastatic breast cancer is always very poor. Thus, it is urgent to develop novel drugs with less toxicity against metastatic breast cancer. A new drug (XC-591) derived from benzothiazole-2-thiol was designed and synthesized in our lab. In this study, we tried to assess effects of XC-591 treatment on primary breast cancer and pulmonary metastasis in 4T1 mice model. Furthermore,...
The development of highly efficient and low-cost electrocatalysts for hydrogen production through water splitting is extremely crucial challenging. introduction transition metals to precious form alloy has been considered an effective strategy regulating the electronic structure catalytic properties. Moreover, particle size reduction also a method achieving electrocatalysts. In this study, we d...
Continuous steady-state gasification tests were performed, in which mixtures of lignite and solid recovered fuel (SRF) fed to a bench-scale facility at atmospheric pressure, loaded with the bottom product high-temperature Winkler gasifier as fluidized bed material. The O2/fuel steam/fuel ratios varied from 0.3 0.4 0.25 0.35, respectively, effects temperature examined different levels (700, 750,...
This work consisted in the preparation of platinum-based catalysts supported on carbon (Vulcan XC-72) and investigation of their physicochemical and electrochemical properties. Catalysts of the C/Pt-Ni-Sn-Me (Me = Ru or Ir) type were prepared by the Pechini method at temperature of 350°C. Four different compositions were homemade: C/Pt(60)Sn(10)Ni(30), C/Pt(60)Sn(10)Ni(20)Ru(10), C/Pt(60)Sn(10)...
We report the full reconstruction of Xc-mesons through the decay chain xc -+ Jlh, Jltl, + p+p-, usmg data obtained at the Collider Detector at Fermilab in 2.6f0.2 pb-’ of Isp collisions at fi = 1.8 TeV. This exclusive xc sample, the fust observed at a hadron collider, is used to measure the xcmeson production cross section times branching fractions. We obtain cr. Br = 3.2zt0.4(stat)f:::(syst) n...
This paper is consisted in the synthesis of platinum-based electrocatalysts supported on carbon (Vulcan XC-72) and investigation of the addition of gallium in their physicochemical and electrochemical properties toward ethanol oxidation reaction (EOR). PtGa/C electrocatalysts were prepared through thermal decomposition of polymeric precursor method at a temperature of 350°C. Six different compo...
Anthogranulomatous cystitis (XC) is an inflammatory condition of the urinary bladder that is benign and rarely seen. XC is a unique disease in which there have been only 26 cases described in the literature, including our case. Patients with XC often present with lower urinary tract symptoms, hematuria, abdominal pain, or abdominal mass. We present the unusual case of an 81 year old female who ...
In this article, sulfonic acid-grafted reduced graphene oxide (S-rGO) were synthesized using a one-pot method under mild conditions, and used as Pt catalyst supports to prepare Pt/S-rGO electrocatalysts through a self-assembly route. The structure, morphologies and physicochemical properties of S-rGO were examined in detail by techniques such as atomic force microscope (AFM), transmission elect...
