I got lot's of these things from portable usb batteries.
But you know, it is really fast! Just almost useless transconductance and no off state, but we can fix it later!
The band gap is not a function of the element alone, but mainly of the crystal structure. Different allotropes of carbon have vastly different band structures.
Diamond has a high band gap, as you mentioned. But Graphene has none, and that is one of the major obstacles of the material.
There isn't a single ARM instruction set, as it is with x86, for exmple. There are many different versions of it. Sometimes there are even significant variations within a family. e.g. Cortex M0 lacks many useful instructions that are only available in the M3/M4.
I have been hacking Assembler level on many different architectures. Cortex M0 is the first one where I actively try to avoid it. It's just no fun.
Such as? Getting new materials into manufacturing is only the last step. Before that there has to be a significant benefit of doing it. And yes, that is usually benchmarked against risks and capex.
The Memristor is actually the same as an RRAM element (Resistive Random Access Memory). Companies other than HP have started working on it long before and are significantly ahead. For example Micron recently presented a multi-gigabit prototype chip. But there is still a lot to be done. HP lacks the funds, manpower and manufacturing muscle to really get anywhere in this area.
I have not yet seen any estimate about the energy efficiency, but I doubt it is very good. This may be good as a emergency battery.

Of course, GE will try to establish its own standards, which are incompatible to those of their competitors (e.g. Siemens).
Also, cheese.
- Nordic VLSI: Wireless ICs like nRF24L01, Basically responsible for the Blue Tooth Low Energy standard.
- AVR: Well known 8-Bit microprocessors. Sold to Atmel
- Energy Micro: Low Power ARM Microcontrollers. Sold to Silicon Labs.
- Phalanx: GPU Cores. Sold to ARM.
Amazing concept anyways.
Saleae suffered a lot from chinese copycats. People copied their hardware for pennies, while saleae was fair enough to provide their software without copy protection.
I think it is only fair they release custom hardware now.
None of these apply to Berlin. Flamebait much?
There are a number of projects out there emulating an Amiga in a FPGA. That makes much more sense.
What won out in the end? Ultra-Low-Cost smartphones, basically offering the same functionality as the western counterparts but with cost drastically reduced by being based on completely domestic chinese designs and Android.
In this case, the problem is rather the education required to use the microscope and interpret the results. A professional will probably manage to finance a $50-$100 microscope, either second hand or as a knock-off, regardless of being in a third world country.
The paper microscope is a great toy or educational device though.
