  1. BackgroundA common feature in photovoltaic (PV) systems is that their power output is unpredictable and unstable in nature (intermittent). Various storage technologies can smooth the stochastic power output levels but are neither cost-effective nor efficient. In addition, many PV systems are typically connected to the power grid, letting users feed...

  2. Current implantable electrodes face many challenges in performance and biocompatibility since rigidity and flexibility cannot be satisfied at the same time. Specifically, for long-term biocompatibility and performance, implanted probes need to further reduce their size and mechanical stiffness to match that of the surrounding cells. However, this m...

  3. Aeronautics has grown exponentially within the past century and innovations within the have propelled an assortment of industries forward. Unfortunately, even though flight is the safest form of travel, there are still present dangers. Snow, ice, and frost formation on aircraft exteriors are known to have caused numerous aviation accidents. This pr...

  4. Orthopedic infection of prosthetic implants can be an expensive and serious medical condition. Bone cement (poly(methyl methacrylate), PMMA) is sometimes used in orthopedic surgery as a carrier for antibiotics and antifungal agents to reduce the risk of infection. However, its effectiveness is limited because only a small fraction of the total ...

  5. Electromagnetic Band-Gaps (EBGs) have been extensively used in low-profile antenna designs because of their in-phase reflection characteristics in certain frequency band(s). EBGs have also been used as attractive ground planes and in checkerboard surface variations. The incident waves on checkerboard patches induce current densities whose amplitud...

  6. In the most recent decades, material characterization has evolved into the microscopic scanning field. Modern sensors are capable of applying electromagnetic radiation to obtain characterization data on set materials. However, current technologies require rotating sensors or sample adjustments. This causes problems in measurements because it risks ...

  7. Due to the ease of application and their desirable properties, epoxies are one of the most commonly used thermoset polymers. They can be used in dental fillings, wind turbines, adhesives, corrosion protectants, and so much more. The reason why epoxy resins are available for such a large range of applications is due to the nature of epoxy structure ...

  8. The CDC estimates that 6.5 million people use some sort of mobility aid, such as canes, walkers, rollators or crutches. Mobility aids can be of great assistance for elderly and disabled patients. However, patients often use their mobility aids incorrectly because they cannot tell how much weight they are putting onto them and lean on them too much....

  9. Shoulder Overuse Syndrome (SOS) occurs from repetitive motion and excessive load put on a shoulder. SOS can affect anyone, from athletes to blue collar laborers, however, wheelchair users make up a significant portion of the affected population. SOS results in swelling, stiffness, instability or inability to complete shoulder movements. In severe c...

  10. With an aging population that continues to grow, more people are undergoing spinal surgeries and may need to wear a brace to stabilize their spine for a period of time afterwards. Additionally, certain spinal injuries, most notably, lumbar spondylosis, require orthoses or braces to prevent worsening of the injury. Conventional braces utilize hard p...
