Imagine being able to live on the moon based on habitable construction to build a permanent base on the moon and on the moon and eventually mars we could collect local resources on the surface and transform them into breathable air then water for drinking, hygiene, farming, rocket propellants and more. Now the data that was collected were articles based off of Geopolymer concrete, a review of some recent developments and how these were collected was using the city tech library portal. So far we used fly ash and wrapped it in aluminum which its heat treated to harden and the temperature is increased after each time. In conclusion, what was found from the findings is that ceramic-like materials prepared at low temperatures by reacting natural aluminosilicates (clays) or aluminosilicate wastes (fly ash and blast furnace slag) may be used for fire- and heat-resistant coatings.
The research goal was to use non-invasive technique to identify the species and gender of bird visitors to two parks in the city. DNA extracted from molted feathers was amplified using PCR and then prepared for sequencing. Sequenced DNA will be compared with genetic barcode for bird species to identify the bird species. The bird species have not been determined. Our Canarsie Pier 7 sample is male (ZZ) as it had a single DNA band, females being heterozygous (ZW) would have double band. Being non-invasive, using molted feathers is a reasonable way of determining presence of bird species. For next steps, we will rerun some samples, complete DNA sequencing, and identify species.
We researched radiation safety practices to reduce dose exposure to a parent or guardian of a minor, to see how we can reduce unnecessary exposure. We used a whole body and half-body phantom; Exposing the whole-body phantom to radiation and comparing how much radiation the half-body phantom was exposed to at various distances (1ft, 3ft, and 6ft). Using a dosimeter, we were able to gather the levels of radiation that the half-body received and assess the impact with or without proper shielding and collimation. We discovered that radiation dose decreases as distance increases and radiation dose further decreases with proper shielding and collimation. In Conclusion, higher radiation safety is achieved with lead shielding coupled with proper distance and collimation.
E.S.G. in electric battery technology is important to the impact of electric vehicles, and other green industries, on the environment, those that support it. We, in our research, collected data from multi-lateral organizations such as the World Economic Fund, International Energy Agency, as well as independent analysts such as GlobalData to both confirm statistics and to form a consistent narrative for our conclusions. We found significant consensus on the negative E.S.G. impacts of Cobalt mining, but great overall E.S.G. impacts of electric batteries. More research should be done into how we can explore for new cobalt reserves in countries closer or more E.S.G. friendly than the existing cobalt supply.
Global warming is a global concern. We are developing imaging techniques, using MRI and x-ray, to locate mineral metals in heterogenous organic tissue of apples. We then expose these apples to temperature stress and image these at different time intervals to model how these minerals might move in organic tissues as a result of temperature changes. The images obtained are further analyzed, using complex statistical and scientific methods to derive information about the nature of these minerals. Our xray method has shown positive results in mapping the movements of minerals that may result from global warming. Further fine-tuning of these methods may one day enable us to even track the movement of these minerals in brain tissue.
Green roof gardens have become an important aspect on urban areas which includes benefits to the environment. This research focuses on the lightweight engineered soil used for these gardens and the changes that can be made to its properties. Lightweight engineered soil was modified to change properties such as maximum media density, water permeability, and moisture content without compromising its weight due to load restrictions from existing buildings. This is done by adding a certain percentage of textile to the soil and the findings show a great significant change to moisture content. These findings conclude that a significant change can be made to lightweight engineered soil and further research can be done for other modifications that can increase the change in these properties.
This project centers on the birth, life, abandonment, destruction, and rebirth of a ca. 1911 dairy barn in the Catskill Mountains. New owners joyfully took to the barn, restoring and securing it for structural stability and future reuse. Then, a windstorm pulled the barn from its foundation and left the building tilting, teetering in the landscape. This project aims to repurpose the remains of the structure as part of a New Environmental Study Center. Managed and operated by City Tech students, alumni, faculty and staff, the center will also establish outreach to inspire the larger community. Progressive building technologies, renewable energy solutions, and sustainable agricultural practices will be explored and utilized.
According to Smart Home Statistics, the number of households using smart home devices in 2022 represents 44.4% of the total number of households. The existing smart automation system focuses more on the young adult audience. However, the target audience for our project will be elderly adults, children, and disabled people. Our project will be able to build a home automation system for our target audience with the help of IoT devices such as ultrasonic sensors, DC Motor, Servo Motor, and LEDs along with Arduino Uno to remotely control electronic devices in the home. Bluetooth module will be used to do Cell phone-based control of home appliances which will let the user control the automated home appliances. With the help of a home automation system, our target audience will get smart homes that will provide automatic lights, fans, and garage doors. Moreover, our research project will save time, provide energy-efficient solutions, and will be budget-friendly for all classes of people. Our future work will focus on having additional sensors to detect smoke and fire inside the house.
This research dives into the viability and financial implication of utilizing an eco-friendly material known as ECOncrete within the Living Breakwaters in Staten Island. ECOncrete was evaluated based on its benefits and logistical requirements for the project. Publicly available information, site visits, interviews, and computer software such as Primavera 6 and Microsoft Powerpoint used to generate the schedule and augment images. As such ECOncrete may enhance marine infrastructure projects by delivering long-term stability and superior structural strength. Further research into other eco-friendly building materials can assist to determine if alternative building materials are not just environmentally friendly but financially viable.
Hello, our names are Lin Mousa and Guitto Charles, this semester we reviewed and assessed research on Alzheimer’s disease (AD), which is an irreversible neurological disorder, that continuously decreases the individual’s memory and thinking skills, suddenly, the ability to carry out the simplest functions of daily living. This project involved X-ray at a low keV range (mammographic range) to exploit the photoelectric detection of minerals in model organic tissues like fruits. It was noted that CT resolution was far better than PET. CT and PET have similar processing but different potentials. We have searched both to explore complementary insights for AD. MRI imaging suffered the ability to give adequate resolution for AD. We have also experimented with a novel hypothesis to map iron in porous organic media as a model of the neurological medium since abnormal iron distribution is implicated in MS, AD, and several other neurodegenerative disorders. CT imaging is proven to be somewhat helpful in the detection of AD disease similar to MRI, multiple repeats CTs seems to show promise in part-reversing the loss (radiation Hormesis).
