Undoped nickel-based catalysts supported on depleted uranium oxide allow one to carry out CO_(2)methanation process under extremely low reaction temperature under atmospheric pressure and powered by a contactless induction heating.By adjusting the reaction conditions,the catalyst is able to perform CO_(2)methanation reaction under autothermal process operated inside a non-adiabatic reactor,without any external energy supply.Such autothermal process is possible thanks to the high apparent density of the UO_x which allows one to confine the reaction heat in a small catalyst volume in order to confine the exothermicity of the reaction inside the catalyst and to operate the reaction at equilibrium heat in-heat out.Such autothermal operation mode allows one to significantly reduce the complexity of the process compared to that operated using adiabatic reactor,where complete insulation is required to prevent heat disequilibrium,in order to reduce as much as possible,the heat exchange with the external medium.The catalyst displays an extremely high stability as a function of time on stream as no apparent deactivation.It is expected that such new catalyst with unprecedented catalytic performance could open new era in the field of heterogeneous catalysis where traditional supports show their limitations to operate catalytic processes under severe reaction conditions.

近年来,负载型金催化剂被视为多相催化工业化进程中的机遇和挑战,因而广受研究.载体的选取可以有效调控纳米金催化剂的化学结构及催化活性.针对载体本身对反应是否具有活性,可将其分为活性载体与惰性载体.活性载体主要为具有还原性的金属氧化物;而惰性载体,诸如碳基材料、氧化硅、氧化铝等,多为反应条件下不具备还原性或不可进行还原处理的材料,不释放活性氧物种,通常不具备显著催化活性.一般情况下,活性载体负载的金纳米粒子(Au NPs)在CO氧化反应、醇类选择性氧化反应、水煤气变换等多相催化反应中均展现出优越的催化活性及目标产物的选择性;而以传统不可还原性材料负载Au NPs时,若非采用特殊的优化手段,该类金催化剂的活性及稳定性通常差强人意.尽管如此,不可还原材料作为惰性载体,亦展现出无与伦比的独特优势,例如其多具有易于调控的表面性能、可调变的多样化微观结构,丰富的地壳储量和易于大规模产业化的优势等.因此,针对不可还原材料负载的纳米金催化剂,探讨创新性的改性手段及其对金催化剂活性与稳定性的理性调控,成为近年来纳米金催化领域中最引人关注的研究课题之一.然而到目前为止,基于惰性载体负载金催化剂的系统性总结工作仍未见报道.作者及其所在团队围绕Au-载体/助剂表界面性质的精准调控及理性验证,以CO氧化与醇类选择氧化等反应为探针,对基于不可还原材料的纳米金催化剂的设计理念和改性手段进行了多尺度的探索.基于本组研究工作及近十年相关文献报道,本综述将以几种典型的不可还原材料为例,针对负载型金催化剂的研究进展进行详尽的阐述.从催化剂设计的理论设想和实践方案入手,对特殊结构材料的独创性研制手段、二元金属掺杂及表面功能化手段、特殊氛围处理等备受关注的改性手段进行归纳.并进一步对改性手段影响表面化学结构、电子结构、Au-载体/助剂间的相互/协同作用、催化剂形貌的实例以及水物种参与对反应的影响等方面展开对比讨论.本综述旨在为致力于金催化研究工作及有志在该领域一展抱负的研究者拓展新的方向,全面诠释不可还原材料作为惰性载体在金催化领域的巨大应用前景,进一步激发不可还原载体负载金催化剂开发的新思路,推动纳米金催化的工业化进程.

Gold nanoparticles have been increasingly used in catalysis, biomedical imaging, biological and chemical sensing, drug delivery, etc. In this study, a straightforward method that allows one to monitor the synthesis of gold sols and their aging, before their fine characterization by sophisticated techniques and before their use is described. Indeed, the “Colloid Thin-Layer Chromatography” method allows one to check the quality of gold colloidal sols during the synthesis. It is also well adapted for monitoring the aging of the sol before the visual observation of its degradation.

Thermal decomposition course of copper acetate monohydrate was monitored by combining diffuse reflectance infrared Fourier transform spectroscopy (DRIFT) coupled with μ gas chromatography-mass spectrometry (μGC-MS) with other analytical techniques (thermogravimetry analysis and in situ X-ray diffraction). Non-isothermal kinetic was examined in air and Ar. A complete analysis of the evolution of infrared spectra matched with crystalline phase transition data during the course of reaction allows access to significant and accurate information about molecular dynamics. While thermogravimetry gives broad conclusion about two steps reaction (dehydration and decarboxylation), in line approach (in situ X-ray and in situ DRIFT coupled to μGC-MS) is proposed as an example of a new robust and forward-looking analysis. While decomposition mechanism of copper acetate monohydrate is still not well elucidated yet previously, the present in-line characterization results lead to accurate data making the corresponding mechanism explicit.

Thirty-five fruits and seventeen vegetables from Martinique were evaluated for total phenol content (TPC), Vitamin C and carotenoid content. TPC, Vitamin C and carotenoid contents ranged from 11.7 to 978.6 mg/100g, 0.1 to 2853.8 mg/100g and 9.7 to 9269.7 μg/100g respectively. Fruits and vegetables from Martinique have equivalent or higher TPC, Vitamin C and carotenoid contents than fruits and vegetables from temperate climates. Cashew apple had high values for all three parameters (55.8 mg/100g of Vitamin C, 603 mg/100g of TPC and 924 μg/100g of carotenoids). Bassignac mango and mamey apple had the highest carotenoid contents, with 3800.3 and 3199.7 μg/100g respectively. Acerola had the highest Vitamin C and polyphenol contents with 2853.8 μg/100g and 727.4 mg/100g respectively. Pigeon peas had high values for all three parameters (569.2 mg/100g of Vitamin C, 978.6 mg/100g of TPC and 364.3 μg/100g of carotenoids). Pumpkin and watercress had the highest carotenoid content, with 9269.7 and 4339 μg/100g respectively. TPC, Vitamin C and carotenoid content were significantly impacted by processing techniques. TPC, Vitamin C and carotenoid contents decreased by up to 75.78%, 100% and 70.18% respectively, depending on the processing technique used.

Purpose: Although controversial, assessment of epidermal growth factor receptor (EGFR) expression is required for the approved indications of Cetuximab in metastatic colorectal cancer (mCRC). With the objective of improving patient selection, “ERBITUX-OUEST” study aimed at analyzing EGFR status in a large cohort of mCRC patients who received cetuximab without preliminary EGFR screening, and assessing the correlation between EGFR status and response to treatment retrospectively. Patients and methods: 332 patients treated with Irinotecan Cetuximab based regimen after progression on irinotecan or oxaliplatin therapy were included. EGFR status was assessed using three available immunohistochemistry (IHC) tests and in situ hybridization in case of negativity. Clinical outcomes of EGFR-positive and EGFR-non-detected (or considered as negative with at least one test) patients were compared. Results: Of the 332 samples centrally screened, 194 were classified as full-positive (i.e., EGFR-positive for all three tests), 86 as full-negative, and 52 as discordant. One third of the 131 negative samples with FDA approved test should be reclassified as positive with at least one of the two others tests. Regarding results from FDA approved test only, neither objective response rate (ORR), progression-free survival (PFS) nor overall survival (OS) differed significantly between EGFR-negative and EGFR-positive patients (P = 0.788, 0.326 and 0.888, respectively). Similarly, comparison of full-negative to other groups did not show any significant difference in terms of ORR (P = 0.507), PFS (P = 0.222) or OS (P = 0.686). Conclusion: These data strongly argue against mCRC patients selection for Cetuximab treatment based on EGFR expression as measured by currently available IHC technics.
