glycerol mono-oleate (gmo) was produced by direct esterification reaction with amberlyst 16 resin catalysts with the efficiency of 86% and was used as a surfactant for synthesis of cofe2o4 nano-particles by surfactant-assisted microwave method. fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd) and scanning electron microscopy (sem) were used to consider the structural and...

Traditionally the machine-learning community has viewed the No Free Lunch (NFL) theorems for search and optimization as a limitation. We review, analyze, and unify the NFL theorem with the perspectives of ``blind"" search and meta-learning to arrive at necessary conditions for improving black-box optimization. We survey meta-learning literature to determine when and how meta-learning can benefi...

In the present work, it is shown that anodic TiO2 nanotubes (NTs) can be decorated with Pt, Pd, Rh, and Au single atoms (SAs) by a simple “dark deposition” approach. Such NTs surface trapped noble metal SAs provide high activity for photocatalytic H2 generation from pure water, i.e., in absence of sacrificial agent. However, metals also act as active centers undesired hydrogen back-oxidation (H...

A growing body of research has focused on so-called 'utilitarian' judgments in moral dilemmas in which participants have to choose whether to sacrifice one person in order to save the lives of a greater number. However, the relation between such 'utilitarian' judgments and genuine utilitarian impartial concern for the greater good remains unclear. Across four studies, we investigated the relati...

Current industrial production of ammonia from the Haber-Bosch process and its transport concomitantly produces a large quantity CO2. Herein, we successfully synthesize inorganic-structure-based catalysts with [Fe-S2-Mo] motifs connecting structure similar to that FeMoco (a cofactor nitrogenase) by placing iron atoms on single molecular layer MoS2 at various loadings. This type new catalytic mat...
