Pd–Pb Alloy Nanocrystals with Tailored Composition for Semihydrogenation: Taking Advantage of Catalyst Poisoning

by Wenxin Niu, Yongjun Gao, Weiqing Zhang, Ning Yan, Xianmao Lu

Abstract

Metallic nanocrystals (NCs) with well-defined sizes and shapes represent a new family of model systems for establishing structure–function relationships in heterogeneous catalysis. Here in this study, we show that catalyst poisoning can be utilized as an efficient strategy for nanocrystals shape and composition control, as well as a way to tune the catalytic activity of catalysts. Lead species, a well-known poison for noble-metal catalysts, was investigated in the growth of Pd NCs. We discovered that Pb atoms can be incorporated into the lattice of Pd NCs and form Pd–Pb alloy NCs with tunable composition and crystal facets. As model catalysts, the alloy NCs with different compositions showed different selectivity in the semihydrogenation of phenylacetylene. Pd–Pb alloy NCs with better selectivity than that of the commercial Lindlar catalyst were discovered. This study exemplified that the poisoning effect in catalysis can be explored as efficient shape-directing reagents in NC growth, and more importantly, as a strategy to tailor the performance of catalysts with high selectivity.

Taking advantage of poisons: The poisoning effect of lead(II) ions can alter the shapes of Pd–Pb alloy nanocrystals. It endows the alloy nanocrystals with superior selectivity for the semihydrogenation of alkynes.

Copper-Catalyzed Oxy-Alkenylation of Homoallylic Alcohols to Generate Functional syn-1,3-Diol Derivatives

by Dean Holt, Matthew J. Gaunt

Abstract

A novel method for the synthesis of a wide range of functionalized 1,3-diol derivatives is reported. Employing a copper-catalyzed oxy-alkenylation strategy, a range of readily available, substituted homoallylic alcohol derivatives and alkenyl(aryl) iodonium salts combine to form syn-1,3-carbonates in excellent yield and with high selectivity. Furthermore, the products formed are amenable to an iterative reaction sequence, thus affording highly complex polyketide-like fragments.

Rick Satava’s Luminous Glass Blown Jellyfish Appear Suspended in Motion

by Kate Sierzputowski

Satava_05

The jellyfish tank is the first environment I always run to when visiting an aquarium. I’m drawn to the luminous quality of the underwater creatures’ bodies, as well as their inclusion in a scene that appears to need no sources of artificial light. Glass artist Rick Satava was also captivated by these creatures in the late 80s, and after a trip to the Monterey Bay Aquarium he began to experiment with sculptures that mimicked the experience of a jellyfish’s elegant glide through the water.

Satava began selling these sculptures in 1990, and by 2002 he was crafting about 300 pieces of work a month. The bright jellyfishes he creates are suspended in the glass that surround them, yet each still appears as if their tentacles are rippling through the water. The glass blown approach works perfectly when translated to the round bell-like shape of the jellyfish’s body, as their natural appearance looks like brightly blown glass.

The California-based artist uses a technique in his sculptures called “glass-in-glass,” which consists of a glass sculpture being dipped into a second, molten glass layer. You can find Sativa’s sculptures within dozens of galleries nationally as well as a few locations internationally including Japan, Spain, Sweden, Switzerland. (via My Modern Met)

From Commercial Sponge Toward 3D Graphene–Silicon Networks for Superior Lithium Storage

by Bin Li, Shubin Yang, Songmei Li, Bo Wang, Jianhua Liu
Thumbnail image of graphical abstract

3D graphene–silicon (G–Si) network is successfully achieved by employing commercial sponge as a template and graphene oxide as a building block, and subsequent magnesium thermal reduction. The unique textural features of the 3D G–Si network including porous structure, good flexibility, high electrical conductivity, and ultrathin hybrid walls lead to the superior electrochemical performances for lithium storage.

Highly efficient, ITO-free and flexible organic photovoltaic cells are demonstrated with 10.4% power conversion efficiency (PCE) through the innovative integration of ultrathin metal film electrode, conductive fullerene interfacial layer, and efficient active blend into a microcavity-embedded device. In addition, a high PCE of 7.21% is achieved for the upsized devices with an active area of 1 cm2.

edens-blog:

i remember in 6th grade public school one of my friends in the class used the word “bungalow” as often as possible and every time he needed to say “house” or “home” he swapped it for “bungalow” and me and the rest of the class thought it was so fucking funny.

so everyone in the class started using it too like saying “I brought my lunch from the bungalow today” or whatever and the teachers HATED IT.

it started getting out of hand when we were learning about the presidents and we often needed to say “the White House” so of course we would say “the White Bungalow” and the teacher was so furious and then there was a ban on the word and if anyone said it they were sent to the office and I remember the kid who started all the bullshit one time got in trouble for something petty like sharing his homework and the teacher said that she was going to call home to him mom and he just stood up and cried out “No, ms_____! Please don’t call home!”

and there was this huge silence because he just raised his voice at the teacher

and then a huge smile spread across his face and he said

“call bungalow instead.”

and I swear the whole class rioted it was amazing
