“…Recently, we fi rst proposed a self-powered electrical process using the energy directly harvested from the environment for splitting water, [ 12 ] desalinating seawater, [ 13 ] and cleaning air pollutants. [ 14 ] Herein, we fabricated a self-powered multi-functional system, which not only electrochemically removes rhodamine B (RhB) and copper ions in wastewater but also simultaneously accomplishes metal electrodeposition by using the energy harvested from the fl owing kinetic energy of wastewater through an R-TENG. [ 15 ] When the R-TENG rotates at a speed of 600 rpm, the system could remove almost 100% of the RhB just within 15 min By harvesting the fl owing kinetic energy of water using a rotating triboelectric nanogenerator (R-TENG), this study demonstrates a self-powered wastewater treatment system that simultaneously removes rhodamine B (RhB) and copper ions through an advanced electrochemical unit.…”

By harvesting the flowing kinetic energy of water using a rotating triboelectric nanogenerator (R‐TENG), this study demonstrates a self‐powered wastewater treatment system that simultaneously removes rhodamine B (RhB) and copper ions through an advanced electrochemical unit. With the electricity generated by R‐TENG, the removal efficiency (RE) of RhB can reach the vicinity of 100% within just 15 min when the initial concentration of RhB is around 100 ppm at optimized conditions. The removal efficiency of copper ions can reach 97.3% after 3 h within an initial concentration of 150 ppm at an optimized condition. Importantly, a better performance and higher treating efficiency are found by using the pulsed output of R‐TENG than those using direct current (DC) supply for pollutant removal when consuming equal amount of energy. The recovered copper layer on the cathode through R‐TENG is much denser, more uniform, and with smaller grain size (d = 20 nm) than those produced by DC process, which also hints at very promising applications of the R‐TENG in electroplating industry. In light of the merits such as easy portability, low cost, and effectiveness, this R‐TENG‐based self‐powered electrochemical system holds great potential in wastewater treatment and electroplating industry.

“…[12] The major challenge of TENGs is still their low output of short-circuit current (I sc ), which hinders their application and therefore motivates researchers to improve the relatively low output current but a high voltage output through modifying the friction materials or optimizing the configuration. [13] Very recently, integrated TENGs through structurally multiplied unit cells connected in parallel have been reported to enhance the current output, which can be successfully applied in sensors, [14] electronics, [15] anticorrosion, [16] SO 2 removing, [17] and water splitting. [18] But the exploration on the application of TENGs is just in its infancy, e.g., to self-power the important synthesis of organic radicals or polymers and organic pollutants treatment have not developed.…”

ÖZET: Nüfusun büyük bir çoğunluğunun kentlerde yaşamaya başlaması ile artan çevre sorunları da hız kesmeden devam etmektedir. Doğal alanlar tahrip edilmekte ve yaşam konforu azalmaktadır. Özellikle kış aylarında yaşanan hava kirliliği tüm canlıların sağlıklı yaşam kalitesini azaltmaktadır. Kentsel mekân içinde yer alan kitle yeşil alanların ise bu durumu iyileştirme yönünde öneli katkıları olduğu bilinmektedir.Canlıların daha konforlu ve sağlıklı ortamlarda yaşam sürebilmesi için bozulan hava kalitesinin teknik ve idari yöntemlerle iyileştirilmesi gerekmektedir. Kent üzerinde yoğunlaşan hava kirliliğinin deşarzı veya azaltılması ile ilgili çalışmalar bu soruna olumlu katkı sağlayacaktır. Bu amaçla; çalışmada Erzurum Kenti'ne ait olan hava kirletici etmenlerden kükürt di oksit (SO2) koordinatları belli olan 20 adet gezici istasyondan alanmıştır. Çevre ve Şehircilik Bakanlığından temin edilen bu değerler kullanılarak, Arc-GIS paket programında geoistatiksel yöntemle hava kalitesi haritası elde edilmiştir. Sonuçlara göre elde edilen kitle yeşil alanlar ile hava kirliliği haritası örtüştürülmüştür. Hava kalitesi haritası bazında çözüm önerilerini sunmak için, iklim ve kirletici parametreleriyle birlikte hipotezler gerçekleştirilmiştir. Kitle yeşil alanların hava kalitesine etkisi belirlenmeye çalışılmıştır.Anahtar Kelimeler: Arc-GIS, hava kalitesi, ,hava kirliliği, kitle yeşil alan ABSTRACT: Enviromental problems continue to increase after most of population started to live in urban. Natural areas are damaged and so life confort decreases. Especially, air polution in winter decreases the healthy life quality of all living things. It is known that large green areas in urban space have important contribution to recovery this case.It is needed that deteriorating air quality should be improved by technical and administrative methods to live in more confort and healthy environment. Studies on the discharge or reduction of air pollution concentrated on urban will have contribute positively on this problem. For this aim, in this study, data for sulfur dioxide (SO2) as factors of air pollutants belong to urban space of Erzurum are taken from 20 of mobile stations which coordinates are known. Air quality map are obtained by using these values on geo statistical method of ArcGIS software. According to results, large green areas and air pollution map are overlaped. Hypotheses are developed by climate and parameters of pollutants to provide the solutions on the basis of air quality maps. It is studied to determine the effect of large green areas on air quality.
