Javier De Riba Spray Paints the Floors of Derelict Buildings With Geometric, Tile-Like Patterns

by Kate Sierzputowski

DCIM100GOPRO

Javier de Riba spray paints abandoned buildings, but not in the way you might imagine. Instead of working on the interior or exterior walls of the buildings he finds, de Riba spray paints the floors, mapping out bright geometric patterns both large and small. The patterns de Riba creates look exactly like tiled floors, making it seem like an element of the building’s past has been elegantly restored.

Like a screen printer, de Riba works layer by layer, first painting the entirety of the space he plans to cover, then working one colored stencil at a time to build up the tile-like effect. The end result is a trick to the eyes both with materials and placement, one never expecting that spray paint formed the intricate patterns on the dusty floors.

The artist and creative designer was born in Barcelona and has worked as an art director in various agencies and studios. His current job is at Reskate Arts & Crafts Collective, a company that develops graphics and communication projects with a focus on sustainability and humane treatment. (via Junk Culture)

Ligand-Free Copper-Catalyzed Negishi Coupling of Alkyl-, Aryl-, and Alkynylzinc Reagents with Heteroaryl Iodides

by Surendra Thapa, Arjun Kafle, Santosh K. Gurung, Adam Montoya, Patrick Riedel, Ramesh Giri

Abstract

Reported herein is an unprecedented ligand-free copper-catalyzed cross-coupling of alkyl-, aryl-, and alkynylzinc reagents with heteroaryl iodides. The reaction proceeds at room temperature for the coupling of primary, secondary, and tertiary alkylzinc reagents with heteroaryl iodides without rearrangement. An elevated temperature (100 °C) is required for aryl–heteroaryl and alkynyl–heteroaryl couplings.

Simply copper: Primary, secondary, and tertiary alkylzinc reagents couple with heteroaryl iodides in the presence of ligand-free CuI without complications arising from β-hydride elimination and rearrangement. The reactions can be extended to the couplings of aryl- and alkynylzinc reagents as well. DMF=N,N-dimethylformamide.

Organocatalytic Activation of the Leaving Group in the Intramolecular Asymmetric SN2′ Reaction

by Yusuke Kuroda, Shingo Harada, Akinori Oonishi, Yousuke Yamaoka, Ken-ichi Yamada, Kiyosei Takasu

Abstract

A Brønsted-acid-catalyzed intramolecular enantioselective SN2′ reaction was developed utilizing trichloroacetimidate as a leaving group. The findings indicated that dual activation of the substrates is operative. This metal-free allylic alkylation allows highly enantioselective access to 2-vinylpyrrolidines bearing various substituents.

Radically Diverse Australian Fungi Photographed by Steve Axford

by Christopher Jobson

mush-1

Photographer Steve Axford (previously) continues his quest to document some of the world’s most obscure fungi found in locations around Australia. Axford lives and works in the Northern Rivers area of New South Wales in Australia where he often has to travel no further than his own back yard to make some of the discoveries you see here. The forms of fungi, slime molds, and lichens he prefers to document seem to have no limit in their diverse characteristics. Axford explained when we first featured his work last year that he suspects many of the tropical species he stumbles onto are often completely undocumented. You can follow more of Axford’s discoveries on Flickr and SmugMug.

NOTHING MAKES ME ANGRIER THAN SOCIALIZED MALE DOMINANCE IN CONVERSATIONS SO LADIES PLEASE LEARN THESE THREE PHRASES AND NEVER BE AFRAID TO USE THEM

  • “Stop interrupting me.”
  • “I just said that.”
  • “DID THE MIDDLE OF MY SENTENCE INTERRUPT THE BEGINNING OF YOURS?”

ALSO WHEN YOU SEE FEMALES IN YOUR LIFE BEING DISMISSED IN CONVERSATION:

  • [Name] was speaking, how about we let her finish?
  • [Name] just said that.
  • [Name] was in the middle of saying something, can you please let her finish?

every fucking day I do this for myself and other women its a constant struggle to be heard

Nichelle Nichols (Uhura on the original series):”Whoopi Goldberg, she’s just marvellous. I had no way of knowing that she was a Star Trek fan. When I finally met her it was her first year on the Next Generation.

She loved the show so much and she told her agent she wants a role on Star Trek. Well agents go ‘Big screen, little screen, no, you can’t do that’. Well you can’t tell Whoopi ‘You can’t do that’.

And so they finally asked, and they had the same reaction at Star Trek office, specifically Gene. And she said, ‘I want to meet him and I want him to tell me to my face. If he tells me he doesn’t want me and why, I’ll be fine.’

Knowing Gene he had to take that challenge, and so he met with her. She said, ‘I just wanted you to tell me why you don’t want me in Star Trek.’

Gene said, ‘Well, I’ll just ask you one question and I’ll make my decision on that. You’re a big screen star, why do you want to be on a little screen, why do you want to be in Star Trek?’

And she looked at him and she said, ‘Well, it’s all Nichelle Nichols’ fault.’

That threw him, he said, ‘What do you mean?’

She said, ‘Well when I was nine years old Star Trek came on,’ and she said, ‘I looked at it and I went screaming through the house, “Come here, mum, everybody, come quick, come quick, there’s a black lady on television and she ain’t no maid!”’ And she said, ‘I knew right then and there I could be anything I wanted to be, and I want to be on Star Trek.’

And he said, ‘I’ll write you a role.’

I know I’ve reblogged this before, and I will undoubtedly do it again.

It matters. And no amount of saying that we’re post-racial or that racism isn’t a thing or that “they just chose the best actor for the role” or otherwise trying to cover up for it will make it okay to keep relegating actors of color to secondary roles, villain roles, stereotyped roles, or no roles at all, and it sure as hell won’t make it okay to keep whitewashing CHARACTERS of color out of the story by casting white actors to play then.

Remember how Martin Luther King Jr. convinced Nichelle Nichols to stay on the show? 

I said “Dr. King, thank you so much. I really am going to miss my co-stars.” He said, dead serious, “What are you talking about?” I said, “I’m leaving Star Trek,” He said, “You cannot. You cannot!”

I was taken aback. He said, “Don’t you understand what this man has achieved? For the first time on television we will be seen as we should be seen every day – as intelligent, quality, beautiful people who can sing, dance, but who can also go into space, who can be lawyers, who can be teachers, who can be professors, and yet you don’t see it on television – until now….”

I could say nothing, I just stood there realizing every word that he was saying was the truth. He said, “Gene Roddenberry has opened a door for the world to see us. If you leave, that door can be closed because, you see, your role is not a Black role, and it’s not a female role, he can fill it with anything, including an alien.”

At that moment, the world tilted for me. I knew then that I was something else and that the world was not the same. That’s all I could think of, everything that Dr. King had said:  The world sees us for the first time as we should be seen.

It matters, man. It honestly does. It mattered then and it still matters.

Some great anecdotes which bear much repeating.

That moment when someone reblogs your reblog and you’re all like “I’M REBLOGGIN’ THIS AGAIN”

Butterflies Have an Extra Stomach Attached to Their Vaginas

One thing you won't find in the story of the Very Hungry Caterpillar is the part where after transforming into a butterfly, he mates with a female who has a Very Hungry Reproductive Tract waiting to devour his sperm. She has a special digestive organ just for this purpose. It's so powerful that it could even compete with the gut that let the caterpillar, in his more innocent days, chew through those five oranges. This sperm-hungry organ is called the bursa copulatrix.

The Effect of Processing Additives on Energetic Disorder in Highly Efficient Organic Photovoltaics: A Case Study on PBDTTT-C-T:PC71BM

by Feng Gao, Scott Himmelberger, Mattias Andersson, David Hanifi, Yuxin Xia, Shaoqing Zhang, Jianpu Wang, Jianhui Hou, Alberto Salleo, Olle Inganäs
Thumbnail image of graphical abstract

Energetic disorder, an important parameter affecting the performance of organic photovoltaics, is significantly decreased upon the addition of processing additives in a highly efficient benzodithiophene-based copolymer blend (PBDTTT-C-T:PC71BM). Wide-angle and small-angle X-ray scattering measurements suggest that the origin of this reduced energetic disorder is due to increased aggregation and a larger average fullerene domain size together with purer phases.
