Medical textiles have a need for repellency to body fluids such as blood, urine, or sweat that may contain infectious vectors contaminate surfaces and spread other individuals. Similarly, viral has yet be demonstrated long-term mechanical durability is major challenge. In this work, we demonstrate simple, durable, scalable coating on nonwoven polypropylene textile both superhemophobic antivirofouling. The treatment consists of polytetrafluoroethylene (PTFE) nanoparticles in solvent thermally...
This work demonstrates a coal-derived functionalized nano-graphene oxide coating applied to fabrics that exhibits antiviral properties even after mechanical abrasion or bleach washing. Nano-graphene is chemically exfoliated from low cost coal and with octadecylamine render repellency properties. The polyethylene terephthalate (PET) fabric wet etching which roughens the microfiber surface for better adhesion liquid repellency. An additional polydimethylsiloxane (PDMS) layer on top of further...
Polypropylene (PP) is used in a wide variety of medical components, but susceptible to bacteria surface colonization and biofilm formation, which lead infections inflammations. In this study, we report on the micro-/nanostructuring functionalization PP substrates through various oxygen fluorine reactive ion etching (RIE) treatments their effects wettability adhesion. We found that treatment creates hydrophilic reduces adhesion by 68.7% compared control, additional nanostructuring surface's...
In this paper, we demonstrate the stain-resistance and high pressure stability of superomniphobic flexible optical plastics.
There is a major need to manufacture highly electrically conductive fabrics with stretch- and wash-durability. In this work, we provide both modeling experiments of the mechanical failure silver ink coatings on knitted fabric. Large thickness metal films are needed for high conductance but tend debond from underlying fabric microfibers that lead cracking failure. Strong adhesion between film microfiber thus key achieving good robustness. The use reactive addresses due in situ reduction...
Transparent electromagnetic interference (EMI) shielding is needed in many optoelectronic applications to protect electronic devices from surrounding radiation while allowing for high visible light transmission. However, very transmission (over 92.5%), EMI efficiency 30 dB) structures have yet be achieved the literature. Bayesian optimization used optimize different nanophotonic (SE) and (T¯ vis ). Below 90% average transmission, sandwich consisting of index dielectric/silver/high dielectric...
Medical textiles are subject to particularly harsh disinfection procedures in healthcare settings where exposure risks high. This work demonstrates a fabric treatment consisting of reactive silver ink and low surface energy PDMS polymer that provides for superhydrophobicity antiviral properties against enveloped herpes simplex virus stocks even after extended ultrasonic bleach washing. The has not been previously reported or compared with nanoparticles. exhibits high static contact angles...
This study evaluates the impact of “Police Response to Uncrewed Aircraft Systems Operations” online training program officers from Daytona Beach Police Department (DBPD). By measuring effectiveness through pretest and posttest assessments considering variables such as educational background, length service, rank, this research underscores training’s potential enhance UAS response capabilities. Employing a self-selection sampling method, engaged 82 voluntary participants DBPD, revealing...
The Center for Homeland Defense and Security identified an increase of active threat events, such as mass shootings, annually since 1999. Literature suggests that 90% shootings were over before law enforcement arrived at the scene first responder response was limited to “surround contain” until Special Weapons Tactics Teams (SWAT) on scene. Using Unmanned Aircraft Systems (UAS) detect which individual type weapon used can provide useful information speed first-on-scene rather than waiting...
