Nanotechnology in waste water treatment
This document discusses how nanotechnology can be used for waste water treatment. It explains that nanoparticles are effective at removing pollutants from water due to their high surface area. Various nanomaterials like metal nanoparticles, carbon nanomaterials, and zeolites can be used. Specifically, nano sorbents can sorbe a wide variety of organic and inorganic contaminants, nano catalysts can increase reaction rates to degrade contaminants, and biomimetic membranes allow for efficient desalination using reverse osmosis. Molecularly imprinted polymers also selectively remove pollutants even at low concentrations. Overall, nanotechnology provides effective, efficient, and eco-friendly approaches to water treatment.
Material tissue interaction
The document discusses material interactions with oral tissues. Local effects depend on a material's ability to distribute and its concentration/exposure time at sites like the pulp, periodontium, root apex or oral mucosa. Systemic effects depend on how substances from materials distribute after ingestion, inhalation, release at tooth apex or oral mucosa absorption. Cytotoxicity tests assess cell death from material exposure. The dentin disk barrier test method places a material on one side of a dentin disk to measure diffusion through dentin and its effect on cells in collection fluid on the other side. Materials can cause inflammation, necrosis, reduced fertility, diabetes, or neurotoxic effects depending on their properties.
The scope of nanotechnology
Nanotechnology involves manipulating matter at the atomic and molecular scale (1-100 nm) to create new materials and devices with fundamentally different properties than their normal-scale counterparts. It has applications in fields like materials science, electronics, medicine, and energy. For example, carbon nanotubes are exceptionally strong and conductive and have potential uses in batteries, solar cells, and composites. While nanotechnology promises many benefits, research is still needed to fully realize its potential and ensure human and environmental safety.

This study aimed to molecularly engineer the extracellular matrix of damaged skin using novel biomimetic proteoglycans (BPGs). The objectives were to determine if BPGs increase skin compliance and evaluate their diffusion behavior in skin. Piezoelectric finger testing showed BPGs exceeded the target of reducing skin's elastic modulus by 25%, increasing compliance. Confocal microscopy imaging revealed BPGs diffused away from injection sites over 24 hours as they integrated into the existing extracellular matrix. In conclusion, BPGs demonstrated molecular engineering of porcine skin's extracellular matrix for the first time, offering potential treatment for aged, diseased skin against tearing and infection at a fraction of the cost of natural proteoglycan injections.

Biodegradation of Polystyrene foam by the Microorganism from Landfill
This document summarizes a research project on biodegrading polystyrene foam. The project aimed to identify microbes from a landfill that can use polystyrene as a sole carbon source. Microbes were sampled from styrofoam and soil in the landfill. Community analysis identified several bacterial species growing on polystyrene, including Caulobacter segnis, Massilia aerilata, and Herbaspirillum seropedicae. Scanning electron microscopy showed signs of polystyrene degradation by microbes from styrofoam and soil. The research suggests certain landfill microbes are capable of biodegrading polystyrene.
Mission impossible
This document appears to be a presentation about isolating bacteria from contaminated soil that can degrade polystyrene foam. It describes collecting soil samples, growing bacteria in a mineral medium with polystyrene foam as the sole carbon source, and isolating 24 gram-positive bacterial isolates, 19 of which were rod-shaped and 5 round-shaped. Traces of degradation were seen on the polystyrene foam in the experimental flasks compared to the controls. Further study is needed to confirm these bacteria can degrade polystyrene foam.
Hacks Health Humanity
The document describes a 48-hour hackathon called HumanityX that brings together technology experts to develop innovations for improving mental health and suicide prevention.

Mission impossible II
This document discusses an experiment to isolate bacteria from soil and foam samples that are able to degrade polystyrene foam. The key steps involved growing bacteria from the samples in a nutrient broth containing polystyrene foam. Bacterial DNA was extracted weekly and analyzed using PCR and gel electrophoresis to identify dominant bacterial species over time. Scanning electron microscopy images show signs of degradation on polystyrene exposed to bacteria from soil and foam samples, but not the control. This suggests bacteria isolated from these environmental samples have the ability to break down polystyrene foam.
Pattern
Pat presented several of their projects including The Bioremediation Game and computer vision and idea development projects. The Bioremediation Game teaches kids about detoxifying chemicals and was well-received. Pat also discussed their mentor Prof. Savaporn Supaphol and encouraged attendees that inspiration can come from many places and that perfect projects are not the most important thing. Breaking problems down and finding the right tools are important for success in creating projects.
