Carbon sequestration in deep underground saline aquifers holds significant promise for reducing atmospheric carbon dioxide emissions (CO2). However, challenges remain predicting the long term migration of injected CO2. Addressing these requires an understanding pore-scale transport CO2 within existing brine-filled geological reservoirs. Studies on fluids through porous media have predominantly focused oil-bearing formations such as sandstone. few studies considered limestone and other...
Single-walled carbon nanotubes (SWCNTs) are ideal channel material candidates for energy-efficient nanoscale transistors; however, it is challenging to achieve uniform alignment of semiconducting SWCNTs with homogeneous chirality. Here, we report the proof-of-concept using organized chirality-sorted via relay technique (ART), where iptycene molecules order through π–π interactions. Top-gated field-effect transistors (FETs) were fabricated aligned (10,3) chirality as channels show an ION 3.8...
Many remote communities struggle to provide a reliable source of clean drinking water.Solar photovoltaic reverse osmosis (PVRO) systems are stand-alone water purification technology that can help alleviate this need.A challenge associated with these is the variation in available energy, and as result, typically designed operate intermittently which cause premature membrane fouling.During design PVRO systems, basic approximations used evaluate performance economic impact fouling caused by...
A model was developed to predict the onset of inertial cavitation within a spiral-wound reverse osmosis module sonicated along its axis from pressure vessel. The aim investigate scalability ultrasonic antifouling for applications. employs one-dimensional discretization represent feed channel, calculating each element's pressure, flow rate, permeate flux, and sonication intensity. Blake threshold assesses whether amplitude at element is sufficient produce cavitation. When applied with...
Many remote communities rely on diesel generators as their primary power source, which is expensive and harmful to the environment. Renewable energy systems, based photovoltaics wind turbines, present a more sustainable potentially cost-effective option for with abundant sun wind. Designing implementing community-owned operated renewable generation alternatives critical infrastructure such hospitals, water sanitation, schools one approach towards community autonomy resiliency. However,...
In this paper, we characterized the microstructure of Indiana Limestone rock samples using X-ray micro-computed tomography (microCT) measurements. Our preliminary results include porosity, and three-dimensional pore reconstructions for each sample. The resulting porosity values are consistent with experimental permeability tests.

Eutrophication, characterized by the excessive accumulation of nutrients, notably nitrogen and phosphorus, in aquatic environments, represents a growing concern contemporary environmental science. Specifically, eutrophication is intricately associated with proliferation algae, giving rise to development dense populations known as algal blooms. Harmful Algal Blooms (HABs), primarily composed cyanobacteria green pose threat ecosystems diminishing water clarity, depleting oxygen levels, and,...
Abstract Escalators have been recommended instead of elevators during the COVID-19 pandemic since it allows transportation for a large number people without being enclosed in small indoor space. tremendous capacity to move numbers and are commonly used various public facilities such as shopping centers, supermarkets, airports, subways. This current study focused on investigating transmission cough droplets from an infected source person traveling Upward Moving Escalator (UME) using ANSYS...
As carbon dioxide (CO 2 ) emissions continue to rise, direct air capture (DAC) has emerged as an important technology for removing CO from ambient combat climate change. The contactor design is a critical factor impacting DAC system performance and costs. This research describes strategy improving the of single unit increase flux while minimizing costs using optimization techniques grounded in experimental data . focuses on 100 m slab modeled utilizing cooling tower scrubber principles....
We investigated the effectiveness of TiO2 cenospheres in reducing concentrations three common harmful compounds, ammonium, nitrate, and nitrite, fish aquariums. These can contribute to more sustainable eco-friendly aquarium filtration systems while also improving health fish. designed a 30-day experiment with treatment groups based on filter type: (1) control group conventional filter, (2) cenosphere (3) dark filter. The water quality was same baseline all groups, each tank monitored daily...
