It mirrors the effects of Double Tap.ĭouble Tap Root Beer costs 2000 points. It also allows the player to lay down equipment such as Claymores faster and makes players operate bolt-action rifles, pump-action shotguns (as well as re-chambering them), and Wonder Weapons such as the Wrath of the Ancients noticeably quicker, as well as raising the firecap for semi-automatic weapons. Double Tap increases the rate of fire (and effectively increasing recoil by the same amount, due to the weapons having less time to settle between shots) of all weapons by 33% and doubles bullet damage (2.0 version only). Who doesn't like the root beer?" - Edward Richtofen, after purchasing Double Tap Root Beerĭouble Tap Root Beer is a Perk-a-Cola featured in Call of Duty: World at War, Call of Duty: Black Ops, Call of Duty: Black Ops II and Call of Duty: Black Ops III in the Zombies game mode. Eui-Sang Yu (common lead author) at KIST, who performed this research, reported that “the findings of this research are meaningful in that ultrahigh-sensitivity detection of microplastics in real-time has become possible, and the proposed approach can be extended to the measurement of the microplastic concentration in various water resources and applied as a water resource securement technology."

What does this mean for future microplastic detection and capture? And thus shortening a previously day-long detection process to several seconds. The team revealed that through their new method, they were able to easily separate particles from their samples through the dielectrophoresis phenomenon. The highest on-site detection performance so far How will this research change current methods of microplastic detection? A step further, synergetic combination with plasmonic nanorods, accomplishes the highest on-site detection performance so far.” “This enables the field-induced active collection of nanoplastics toward the optical sensing area from remote areas in a rapid manner, integrating conventional technical skills of preconcentration, separation, and identification in a single process. The method of tracking microplasticsĪccording to their research, the team obtained “effective Raman signals in real-time from underwater nanoplastics with ultralow concentrations via AC electro-osmotic flows and dielectrophoretic tweezing.” Researchers used an Electro-Photonic Tweezer to capture and detect trace amounts of microplastics through surface-enhanced Raman scattering, an application in safe water resource management technology. Following their research, the team reported developing a real-time detection system for nanoplastics using light.Ī real-time detection system for nanoplastics using light Yong-sang Ryu at the Brain Research Institute of the Korea Institute of Science and Technology (KIST) used an electro-photonic tweezer and metal nanoparticles to concentrate ultrafine nanoplastics within a short period. Protecting the planet from microplastics using light technologyĪ research team of Dr. Current detection processes require a few hours or even days to reach completion and present significant costs. With the detection of microplastics so limited due to their size and concentration, the removal process seems impossible. With news about the prevalence of microplastics in our water, many wonder about their impact on the human body and our environment.
Reports show that the major rivers in South Korea have the highest levels of microplastic concentrations globally. Scientists have revealed that we ingest around 2000 microplastics a week – the equivalent of the weight of a credit card. Microplastics continue to be discarded from our daily lives and enter ecosystems at a size between one and 1000 nanometres.
