Kazakhstan’s Minister of Communications and Informatics has blocked the Tumblr site because it contained 60 sites of terrorism, extremism, and pornography in 2015.
Introduction
Biochar Cladding is a carbon-negative building material made from the pyrolysis of biomass. It can be used as cladding or insulation, offering improved thermal performance and reducing the building’s carbon footprint. Biochar can be utilized as a supplement for plaster or concrete blocks at a ratio of up to 80% when combined with mud, limestone, and cement mortar. This mixing…
Koenigsegg Jesko Attack, 2024. The Danish hypercar maker have delivered an Attack variant with raw carbon fibre bodywork and 24 K gold trim. Gold leaf has been used on front canards, the wing mirror arms, a central element on the front fascia, the aerodynamic flics on the side skirts, and the rear wing endplates.

are u gonna publish this in the algobox or wherever else? i need to have these goobers on my computer (others who have algodoo would probably love it too)
HI!
The Pilot Falcon (older generations were sold in the US as the Namiki Falcon for whatever reason) is a japanese fountain pen manufactured by Pilot!
it's often referred to as the best modern flex pen, or the best gold nib for a beginner! Tldr for people who aren't pen nerds, a flex pen is a pen that...well, flexes! Most pens have some sort of "flex" to them that results in some sort of line variation, but flex pens can handle a relatively higher amount of pressure. Think like a G nib used in a lot of manga. Old pens were the MASTERS at this, and a good bit of that is due to the nibs being made of gold, which naturally has a "bounce" to it that modern steel nibs have a really hard time living up to. Most people wax poetic about Waterman or other vintages like that because of it. Even modern gold nibs can't really keep up with the gold nibs of yore, but the Falcon is considered to be one that can. I do think legally it's considered a "soft" nib, meaning it's not truly a flex pen but has a lot of flex qualities to it, but some terms that get used are used interchangably so. idk. True flex nibs aren't really a thing in fountain pens these days outside of Noodler's Ahab and Konrad (which are their own nightmare and a half tbh).
The Falcon prized amongst artists for it's very fine nib, which Japanese pen manufacturers like Pilot and Platinum are known for. A Japanese Fine is comparable to a Western (Kaweco, Lamy) Extra fine, and a lot of these pens come in an EF, F, and M. It gets alot of nice line variation despite being so small, and is really an all-around great pen, if legend is to be believed :]
An alternative to buying the Pilot Falcon would be getting the Pilot 912 FA, which has something called the "Falcon Nib," not to be confused with the actual pen. They actually look pretty different. The FA nib (right) has these weird cuts on their side that help with flexing and allow it to mimic a full-flex nib, but again. According to legend, modern pens don't flex like vintage pens do, but it IS pretty close.

I've never used either myself, but I'm pretty picky about my pens and so I don't know if I'd ever pay upwards of $200 unless I got familiar with the nib first tbh....The falcon's nib isn't offputting to me like many feel about it, but I'm particular about aesthetics and the feedback on paper and I can't tell if I like them just from looks alone lol. Right now, I don't have much experience with pilot nibs, but if i were to get a pilot pen, tbh I'm looking at the Pilot Elite/e95s in a fine or medium, or a vintage platinum pocket pen.
Anyways that's that and this is also that. *twirls so elegantly and then collapses onto the ground in slapstick fashion*
Nickel-laden black gold converts CO2 to chemicals using solar energy and green hydrogen
CO2 hydrogenation with green hydrogen is one of the best processes to combat climate change and can provide a single solution to three challenging problems, 1) excessive CO2 levels, 2) the temporal mismatch between solar electricity production and demand, and 3) hydrogen gas storage. However, the CO2 hydrogenation reaction needs very high temperatures, causing quick deactivation of the catalyst.
In new work published in ACS Nano, researchers at Tata Institute of Fundamental Research (TIFR), Mumbai, asked the question of whether this high-temperature CO2 hydrogenation can be catalyzed at room to moderate temperature via plasmonic excitation of H2 and CO2 using plasmonic catalyst. They have demonstrated that plasmonic black gold-nickel efficiently catalyzes CO2 hydrogenation using visible light.
The reaction took place as low as 84 to 223°C without external heating. Researchers found a multifold increase in the catalytic activity as compared to DPC-C4 to the extent that measurable photoactivity was only observed with DPC-C4-Ni. It showed the best-reported CO production rate of 2464± 40 mmol gNi-1 h-1 and selectivity greater than 95% in the flow conditions. The catalyst showed extraordinary stability (100 h).
I can't tell if I've just hit a really good string of books / tv, or if I've just hit a reset button on my brain by cutting out 99% of social media, reality TV, and mindless youtube videos...
