Manufacturing Approaches of Nanorobotics

on 23/06/2023

Given that nano-robots will be minuscule, doing microscopic and macroscopic activities would likely require a very large number of them to collaborate. These nano-robot swarms include both those that can replicate freely in the natural environment and those that cannot (such as utility fog). Some supporters of nanorobotics believe that self-replicating nanorobots do not necessarily make up purportedly productive nanotechnology and that the process of self-replication if it were ever developed, could be made inherently safe. This position is in response to the grey goo scenarios that they earlier helped to spread. In the context of nanomedicine, Robert Freitas has provided a thorough theoretical study of nanorobotics, addressing particular design challenges including sensing, power communication, navigation, manipulation, locomotion, and onboard processing. These talks sometimes don’t even reach the level of specific engineering and remain at the level of unbuildable generality.
The construction of nanomachines from molecular parts is an extremely difficult process. Because of how challenging it is, many engineers and scientists are still collaborating across disciplines to make advancements in this new field of development. It follows that the significance of the various ways now used to create nanorobots is pretty clear: A competition for nanorobots is currently underway, much like how technological research and development fueled the space race and nuclear arms race. Nanorobots have a lot of room to grow and belong in the category of developing technologies. The recent work on nanorobot development and research by major corporations like General Electric, Hewlett-Packard, Synopsys, Northrop Grumman, and Siemens is one of the reasons; additionally, surgeons are becoming involved and are beginning to suggest ways to use nanorobots for routine medical procedures.
A potential method for producing nanorobots for typical medical applications, such as surgical instrumentation, diagnosis, and medication distribution, involves combining nanoelectronics, photolithography, and novel biomaterials. The electronics sector has been using this technique for nanoscale production since 2008. Therefore, it is necessary to incorporate useful nanorobots into nanoelectronics devices, enabling teleoperation and increased capabilities for medical instruments.
Several papers have shown how artificial molecular motors may adhere to surfaces. It has been demonstrated that these simple nanomachines can behave like machines when placed on the surface of a macroscopic substance. The surface-anchored motors may be used to position and move nanoscale materials on a surface in a conveyor belt-like way. The mission of the Robert Freitas and Ralph Merkle-founded Nanofactory Collaboration, which consists of 23 researchers from 10 organizations and 4 countries, is to create a practical research agenda that is focused on creating positionally-controlled diamond mechanosynthesis and a diamondoid nano factory that can produce diamondoid medical nanorobots.
Bio-hybrid systems, an emerging field, combine biological and artificial structural components for biomedical or robotic purposes. Nanoscale materials such as DNA, proteins, and nanostructured mechanical components are examples of the components that make up bio-nanoelectromechanical systems (BioNEMS). Direct nanoscale feature writing is possible with thiol-ene e-beam resist, and the surface of the naturally reactive resist can then be functionalized with biomolecules. Other methods guide magnetic particles about the body by attaching a biodegradable substance to them.

Vietnam’s journey of becoming carbon-neutral by midcentury US$135 bn power plan for 2030; wind energy to touch 17.6% and solar power 13.0%

on 23/06/2023

Vietnam’s prime minister approved a long-awaited power plan for this decade that needs $134.7 billion of funding for new power plants and grids, the government said late this week, in a move that may help unlock billions of dollars of foreign investment.
The plan, known as PDP8, is aimed at ensuring energy security for the Southeast Asian country while it begins the transition from its current heavy reliance on coal to becoming carbon-neutral by midcentury.
Amid internal squabbles and work on complex reforms, the plan has been delayed for more than two years, and has seen a dozen of draft versions before the approval by Prime Minister Pham Minh Chinh, which now needs the formal green light from the rubber-stamp parliament, possibly this month, before its final adoption.
The plan is important to unlock an initial investment of $15.5 billion in green-transition funds pledged to Vietnam in December by the Group of 7 (G-7) nations and other wealthier countries. Half the funds will come from the public sector and the rest from private investors.
After the deal, negotiators have struggled for months to progress on preliminary work to allocate the funding, multiple officials told Reuters, as Vietnam officials maintained their reticence to accept loans, which are by far the biggest component of the promised public funds.
One diplomat from the G-7 donors’ group told Reuters on Tuesday the approval was an important step, necessary to unlock funding for renewable projects, especially offshore wind. It was however not completely in line with G-7 goals, the diplomat added, as the country will still heavily rely on coal this decade.
To complete its transition to carbon neutrality with total phase-out of coal by 2050, the government estimates it needs a whopping $658 billion, of which one-fifth would have to be disbursed this decade.
The industry ministry, which prepared the document, said in a statement late on Monday that, under the plan, half of office buildings and homes in Vietnam would be powered by rooftop solar panels by 2030. The country would also aim to generate green energy for exports, with a target of 5-10 gigawatts (GW) by 2030.
The statement did not provide full details of the plan.
A draft of the PDP8, dated May 10 and seen by Reuters, showed the plan would more than double the country’s power generation capacity to 158 GW by 2030 from 69 GW at the end of 2020.
Power plants using domestic gas and imported liquefied natural gas (LNG) would be the main source of the country’s power generation mix by 2030, accounting for 37.33 GW, or 23.6%, according to the draft, with LNG accounting for the lion’s share.
Coal would still account for 19% of the mix by 2030, followed by hydropower with 18.5%, wind energy with 17.6% and solar power 13.0%, according to the draft.
The ministry did not respond to a request for comment about the draft.
