UCR is where you want to go if you're going for Geology or Ag/Hort, you aren't really trying to go there for SWE or EE, it isn't exactly known for those sorts of programs.
Source: I live right next to their citrus and asparagus test fields and often visit their geology building to use their XRD and XRF systems.
The sad part about declaring it's about oil is that Venezuela's oil is complete and absolute garbage that is littered with heavies. They need to import naptha to mix into the super-heavy crude in order to make it into a state pumpable through pipelines. To boot, the USA doesn't have a whole lot of heavy crude refining capability, as a huge chunk of our reserves is light oil, and as such the majority of our refineries (like the ones on the Gulf Coast) are set up for processing that type of crude. A fat chunk of the heavy crude processing capability for North America lies in Canada for their tar and oil sands.
Reality - Roughly 2/3 - ~67% - of known hydrocarbon reserves are located in the North American continent. Venezuela is a modest ~17-18%.
If anyone should be invaded for world oil security - it's us.
Not present and ultimately-cursed - using LEDs not only as bridge rectifier but also as the voltage drop for power conditioning before going into a processing IC.
Nothing new, Applied Diamond has made this stuff for several years and it is incredible. Imagine putting a 15w LED on a typical 20mm star board made of diamond - you do not need a heat sink. Just minor air flow over the package is enough.
A little unlike IEEE to be nearly half a decade out of the loop.
I think what they have grown diamond on the transistor which then bonds to the substrate through a SIC interlayer.
From what I understand their idea seems to be that since most heating occurs at channels they act like hotspots and therefore it would be much better to drain away heat from them directly.
This is different from creating transistors on a diamond substrate.
naturally, graphite has similarly high thermal conductivity along the layer direction (which is basically graphene), and one would think that there should be some way to put such a thin layer of graphite/graphene on top (or inside) the chip to achieve similar results.
There are many places on earth where people live no different from what we lived like 10,000s of years ago. You can just go there, you know, you can just do things. You are an adult.
"Amazing hematite crystals mixed with copper with strong assay signs of gold underneath."
Did you actually assay out anomalous gold concentrations or are you seeing the sulfides and oxides that are associated with gold? If the former, what sort of concentration are you getting?
I have only assayed samples from the iron cap. You would not expect to find much in that part of the formation but it still came in at 1-2g/ton. There is a large area of visually striking bornite[0] that I have not yet been able to properly sample which is roughly the area you would expect the gold to concentrate. It is in the walls of a narrow, deep canyon at high elevation. The region was mined for gold/copper a century ago, so the existence is not surprising.
The location makes access extremely challenging. It requires 3 hours of hiking, assuming you are fit, and borderline technical mountaineering once you get close to the site. The lower parts of the canyon are also under tens of meters of ice most of the year, which creates a separate set of safety issues. When these mountains were prospected in the 1920s, it would have been underneath a deep permanent snow field. I've visited some of the old gold mines in the area for calibration and this deposit appears substantially larger than those.
The discovery was accidental. I was looking for a waterfall I had seen on satellite imagery in the backcountry and came across an enormous chunk of molybdenite[1] while climbing across granite scree. I made several trips to find the source of the molybdenite higher up the mountains, which I never did, but while searching for that I localized a bunch of other beautiful sulfide/oxide mineral specimens to the above canyon. It gives me a great excuse to explore parts of the mountains no one has been into before.
Honesty I know a bunch of people who are burntout climbers and burntout geologists - sounds like a blast. Fun mineralogy with climbing that’s not…super exotic but still fun? I’d pay for it.
Some of those climbs are dangerous though. The Chambless Skarn has a vertical wall of solid epidote you have to scale to reach a massive pocket of world-class hedenbergite, at the top of the mountain. That wall is a few stories tall, and your only grip is the side walls of the rock around you.
With Japan's artificial womb technology, sure! We can also create sperm or egg cells from just about anything and implant that into the womb.
ICE is gestapo. And I'll keep beating them down every chance I get. Can't screw with someone that mines nuclear materials very easily.
