Katherine Macpherson, 42, who previously modeled pictures of dresses on Ebay, has since discontinued her job due to relentlessly thirsty, and grossly insensitive pursuits on the part of Ebay's horny internet trolls. Macpherson says she'll receive up to 20 dirty messages a day; and we're talking dirty and explicit enough that they weren't appropriate for print.
"One person who sent me several unanswered messages and then became more insistent before sending me a picture of his penis was on my blocked bidder list and should not have been able to contact me but somehow still managed it.
"I reported him and was informed by eBay that if they received any more complaints from other users they may consider suspending his account. Via: The Sun
We're glad to hear that Ebay stepped up to support the woman just trying to do her job, and haven't heard yet on whether the issue's been resolved.
We're talking way back in August of 2014, Ariana Grande released her album, My Everything; and it came and went, and nobody thought too much of it. Yet, now here we are: years later, someone had to go and kick the hornet's nest of conspiracy theorists, hungry to debate something on Twitter. Naturally, this is the perfect opportunity: how in the hell is she sitting on that stool?
Herein we report the first examples for the use of redox-active guanidines as catalysts in the green oxidation of organic molecules with dioxygen. In one half-reaction, the oxidized state of the redox-active guanidine is converted to the reduced, protonated state, thereby enabling dehydrogenative oxidation of the substrate (3,5-ditertbutylcatechol o-benzoquinone, benzoin benzil, and 2,4-ditertbutylphenol biphenol). In the other half-reaction, efficient re-oxidation of the guanidine to the oxidized state is achieved with dioxygen in the presence of a copper catalyst. The results pave the way for a broader use of redox-active guanidines as oxidation catalysts.
Wearable Fabrics with Self-Branched Bimetallic Layered Double Hydroxide Coaxial Nanostructures for Hybrid Supercapacitors
Fabrication of hybrid MOF-on-MOF heteroarchitectures can create novel and multifunctional platforms to achieve desired properties. However, only MOFs with similar crystallographic parameters can be hybridized by the classical epitaxial growth method (EGM), which largely suppressed its applications. Herein, we demonstrated a general strategy called internal extended growth method (IEGM) for the feasible assembly of MOFs with distinct crystallographic parameters in an MOF matrix. Various MOFs with diverse functions could be introduced in a modular MOF matrix to form 3D core-satellite pluralistic hybrid system. Additionally, the number of different MOF crystals interspersed could be variable on demand. More importantly, the different MOF crystals distributed in individual domains could be used to further incorporate functional units or enhance target functions.
We have developed a catalytic method for hydroalkylation of allenes using alkyl triflates as electrophiles and silane as a hydride source. The reaction has an excellent substrate scope and is compatible with a wide range of functional groups, including esters, aryl halides, aryl boronic esters, sulfonamides, alkyl tosylates, and alkyl bromides. We found evidence for the reaction mechanism that involves unusual dinuclear copper ally complexes as catalytic intermediates. The unusual structure of these complexes provides rationale for their unexpected reactivity.

If this looks familiar it's because yesterday I uploaded it with a typo, in which the dad was offering to taste the kid's sore throat. That may literally be the creepiest typo in the history of typoes.
Hey New York! We're coming to you next week. The events are ticketed and relatively small, so grab one whilst available!
The development of base metal catalysts for the synthesis of pharmaceutically relevant compounds remains an important goal of chemical research. Here, we report that cobalt nanoparticles encapsulated by a graphitic shell are broadly effective reductive amination catalysts. Their convenient and practical preparation entailed template assembly of cobalt-diamine-dicarboxylic acid metal organic frameworks on carbon and subsequent pyrolysis under inert atmosphere. The resulting stable and reusable catalysts were active for synthesis of primary, secondary, tertiary, and N-methylamines (more than 140 examples). The reaction couples easily accessible carbonyl compounds (aldehydes and ketones) with ammonia, amines, or nitro compounds, and molecular hydrogen under industrially viable and scalable conditions, offering cost-effective access to numerous amines, amino acid derivatives, and more complex drug targets.
