The document discusses the EvoGrid, a worldwide computational effort to simulate the chemical origins of life on Earth. The EvoGrid uses a large network of computers to simulate a primordial soup and model the emergence of increasingly complex structures and reaction sequences from simple starting conditions. The goal is to gain insights into how life may have first emerged on our planet through a bottom-up, chemistry-first approach rather than assuming the prior existence of biological functions or mechanisms.
Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale. A nanometer is one-billionth of a meter. A sheet of paper is about 100,000 nanometers thick; a single gold atom is about a third of a nanometer in diameter.
Nanotechnology involves manipulating materials at the nanoscale, which is less than 100 nanometers. It has been used for over 2000 years to dye hair and create stained glass but the term was coined in 1974. Nanotechnology has applications in medicine by using nanoparticles to target drug delivery to diseased cells, electronics by improving displays and memory density, food by altering taste and safety, space by enabling lightweight spacecraft, water by removing contaminants, and fabrics by improving properties without added weight. It offers powerful new products through intertwining with other technologies to create new possibilities.
The document discusses the origins and definitions of nanotechnology. It traces the concept back to physicist Richard Feynman in 1959 and his vision of manipulating materials at the atomic scale. K. Eric Drexler further popularized the idea in 1986 by proposing self-replicating nanomachines that could build other machines. The document defines nanotechnology as engineering and technology conducted at the 1-100 nanometer scale, about 1 million times smaller than the width of a human hair. It provides examples of potential nanorobots and their applications in areas like cancer treatment, drug delivery, and medical imaging.

Title: Gravitational wave detection with orbital motion of Moon and artificial
Abstract:
In this talk I will describe some recent ideas to find gravitational waves from supermassive black holes or of primordial origin by studying their secular effect on the orbital motion of the Moon or satellites that are laser ranged.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Basically a heat-exchange engine, its single-atom acts as
both fuel and power plant and is heated by electrical noise
and cooled by laser beam.
The Scientists who are behind the invention don’t have a
particular use in mind for the engine.
But it’s a good illustration of how we are increasingly able to
replicate the everyday machines we rely on at a tiny scale.

organs to target specific sites precisely.
