Home to Sunlite Water Adventure theme park - an ideal getaway for a toasty summer day - visitors can choose from swimming in the world’s largest recirculating pool, racing down one of the adrenaline-pumping 130-foot waterslides, getting soaked at Typhoon Tower, tackling the Ninja Warrior-esque course, or simply relaxing on a cabana with a refreshing drink in hand! ![]() Not to be confused with the famous Brooklyn Coney Island, Cincinnati’s Coney Island Park holds a special place in the hearts of locals and is an absolute must-visit for out-of-towners. Say hello to the Fiona, the world-famous hippo feed the lanky giraffes catch a live feeding learn all about the wildlife on show through the trainer-led educational talks, walk around with white tigers and say “G’day” to the kangaroos!įor something interactive, swing through the Jungle Trails’ interactive elements, jump on the Safari Train, take a spin on the Conservation Carousel, or sit front row in the 4-D Theater! 2 – Zoom down waterslides at Coney Island Park Home to over 500 friendly creatures of all shapes and sizes, not to mention more than 3000 different varieties of local and imported plants, the family-friendly Cincinnati Zoo and Botanical Garden boasts a reputation that precedes it – as both the second-oldest American zoo and one of the top-rated. So, without further ado, let’s get stuck into it! 1 – Spend the day at the Cincinnati Zoo & Botanical Garden Whether you’re a sports nut, diehard foodie, culture vulture, or nature lover, the list of things to do in Cincinnati is overflowing with activities that will get your adrenaline pumping, heart racing, and taste buds tingling. Moreover, the cross bridged-bowtie nanohole array allows the tunability of the position of the hotspot with the rotation of the direction of the polarization of incident field.Straddling the Ohio River and the northern Kentucky border, vibrant and underrated Cincinnati boasts an eclectic mix of people and places dishing up a diverse selection of fascinating museums, historical sites, sprawling green-soaked parks, and a melting-pot of restaurants and bars that (make sure to sample the Cincy Chilli) have propelled the so-called Queen City to stand out among its Midwestern counterparts. The bridged-bowtie nanohole arrays and cross bridged-bowtie nanohole arrays exhibit very high electric field enhancement factors (EFs) at more than one wavelength, and can therefore be used to obtain a multi-wavelength SERS response. The effects of varying the gold film thickness and the diameter of the bridged-bowtie nanoholes forming the arrays were also analyzed. The resonance wavelength of these arrays of nanoholes can be tuned by altering the size of the nanoholes. It was observed that the bridged-bowtie nanohole arrays and the cross bridged-bowtie nanohole arrays can be employed as effective SERS substrates in both the transmission mode and the reflection mode. In addition, it was observed that an electromagnetic SERS enhancement factor of at least 10 8 is spread over a large area (500 nm 2 in each periodic unit of the array), thus increasing the average enhancement factor. ![]() This electromagnetic SERS EF (of ~10 9) is spread over a hotspot region of ~100 nm 2 (in each periodic unit of the array), which is larger than the case of nanopillar arrays. ![]() It was observed that bridged-bowtie nanohole arrays and cross bridge-bowtie nanohole arrays exhibit a highest electromagnetic SERS enhancement factor (EF) of ~10 9, which is orders of magnitude higher than what has been previously reported for nanohole arrays as SERS substrates. Numerical simulations based on the finite difference time domain (FDTD) method are employed to determine electric field enhancement factors (EFs) and therefore the electromagnetic SERS enhancement factor for these SERS substrates. These SERS substrates not only exhibit large electromagnetic enhancement of SERS but also have the SERS enhancement spread over a much larger area than what could be present in SERS substrates consisting of nanopillar arrays or nanopillar plasmonic nanoantennas. In this paper, we present bridged-bowtie nanohole arrays and cross bridged-bowtie nanohole arrays in a gold thin film as surface enhanced Raman scattering (SERS) substrates.
