Quite enough energy density and very good power density for stationary energy storage, with zero fire danger. Reasonably cheap, too.


It’s more like NiCd but better power and more cycles (and no memory effect).


Abstract
Downsizing metal nanoparticles into nanoclusters and single atoms represents a transformative approach to maximizing atom utilization efficiency for energy applications. Herein, a bovine serum albumin-templated synthetic strategy is developed to fabricate iron and nickel nanoclusters, which are subsequently hydrothermally composited with graphene oxide. Through KOH-catalyzed pyrolysis, the downsized metal nanoclusters and single atoms are embedded in a hierarchically porous protein/graphene-derived carbonaceous aerogel framework. The carbon-supported Fe subnanoclusters (FeSNC) as the negative electrode and Ni subnanoclusters (NiSNC) as the positive electrode exhibit remarkable specific capacitance (capacity) values of 373 F g−1 (93 mAh g−1) and 1125 F g−1 (101 mAh g−1) at 1.0 A g−1, respectively. Assembled into a supercapacitor-battery hybrid configuration, the device achieves an excellent specific energy (47 W h kg−1) and superior specific power (18 kW kg−1), while maintaining outstanding cycling stability of over 12 000 cycles. Moreover, FeSNCs displayed a significantly reduced oxygen evolution overpotential (η10 = 270 mV), outperforming the RuO2 benchmark (η10 = 328 mV). Molecular dynamics simulations, coupled with density functional theory calculations, offer insights into the dynamic behavior and electronic properties of these materials. This work underscores the immense potential of metallic subnanoclusters for advancing next-generation energy storage and conversion technologies.

My first interest was in running Unix for uucp Usenet, early 1980s. Never happened since I was poor, so it took DSL availability some 20+ years ago to run a Debian server at home. Around 1997 I ran my own Linux box on a university network, which ran a web server.


Precious few people bother with alternative ROMs. GOS users are a small subset of that. The impact on new Pixel device sales is very close to zero. In future, there is the promise of a new OEM. I wouldn’t sweat it.


I prefer secure systems. Buy used/refurbished for not supporting Google.
Nothing is more elitist than arguing semantics on a fringe de la fringe platform.
As a stinking elitist I live in a nice world where I don’t have to care about what other people do.


No, the Fairphone hardware platform doesn’t meet minimal security features of the GOS project. You could say they chose not to compromise on security rather.


No, currently only on Pixels. Plans to support another future platform exist.


So there are no good things about stock Pixels.


It isn’t. It is why Russia has launched their Max messenger, are throttling Telegram functions and is forcing patriotic channels which are already registered with Roskomnadsor over to Max.


I run Ubiquity AP (used to be flashed to OpenWRT but now stock) as well as Mikrotik, all local. Firewall is opnsense. NAS is FreeNAS, but not really use it at the moment. zfs is great. If you really need 48 port L3 switches, look into whitebox. I use used enterprise gear for lab, too much noise and power draw and no real use for terabit L3 at home.


Use opnsense instead.


Looks good to me. But without at least some borderline functional (e.g. Hetzner, StackIt) sovereign domestic cloud vendors you’ve still got all your eggs in one US-owned basket. Everybody knew that, but nobody cared until the rooster crowed.


I call that ”installing software” on devices I really own, those with free/libre OS.
What a curious article. The Russians have made mincemeat of all Abrams and Leopards delivered, yet the author extolls their virtues. They say they failed because Ukrainians are not using them properly. Yet in a recent combat simulation Ukrainians slaughtered NATO forces. Draw your own conclusions.
