C-saturated Pd nanoparticles with an extended phase boundary to ZrO evolve from a Pd Zr precatalyst under CH dry reforming conditions. This highly active catalyst state fosters bifunctional action: CO is efficiently activated at oxidic phase boundary sites and Pd C provides fast supply of C-atoms toward the latter.

The aim of this study was to analyse the effect of breathing parameters, age, gender and disease status on the lung doses of the two ICS + LABA fixed combination dry powder drugs. Breathing parameters of 113 COPD patients were measured while inhaling through emptied NEXThaler® and Ellipta® inhalers and the corresponding lung doses were calculated. Lung dose of Foster® NEXThaler® was superior to the lung dose of Relvar® Ellipta® in around 85 % of the patients.

Understanding of the structure and interfacial merits that reactive metal-organic frameworks (MOFs) undergo is critical for constructing efficient catalysts for non-thermal plasma-assisted conversion of greenhouse gases. Herein, we proposed a free-standing bimetallic (Co/Ni) MOFs supported on bacterial cellulose (BC) foams (Co/Ni-MOF@BC) toward the coaxial dielectric barrier discharge (DBD) plasma-catalytic system, of which the Co/Ni ions coordination demonstrated an intriguing textual uplifting of the malleable BC nanofiber network with abundant pores up to micrometer-scale, which could impart a more intensive predominant filamentary microdischarge current to 180 mA with stronger plasma-catalytic interaction. Remarkably, compared to the monometallic MOF@BC foams, this bimetallic Co/Ni-MOF@BC also delivered a substantially improved alkaline absorption ability as further confirmed by the CO- temperature-programmed desorption (TPD) result.

Article Synopsis
- The study uses density functional theory (DFT) to examine how low oxygen vacancy formation energy affects the catalytic performance of chemical looping dry reforming of methane (CL-DRM) when metal ions Zn and Nd are co-substituted on CeO(111) surfaces.
- Results show that the co-substituted surfaces have a very low oxygen vacancy formation energy (-2.05 eV), enhancing the CH conversion process compared to pristine surfaces, with the rate-limiting step being the dehydrogenation of CH.
- However, while the co-substituted surfaces promote better reaction performance, high energy is required for syngas desorption and CO selectivity is reduced, indicating a balance is needed to prevent excessive

The presence of abundant hydroxyl groups on the surface of AlO can promote the dispersion of Ni species but produce an inactive NiAlO phase at high temperatures. Moreover, the catalysts prepared by the conventional incipient wetness impregnation method lack the sites for the activation of CO, which leads to coke deposition and thus affects the catalyst activity. The above restricts the utilization of Ni in conventional Ni/AlO catalysts.
