In the present study, a model drug, with its low permeable and low aqueous soluble properties, was selected to produce microparticles using an anti-solvent precipitation technique with two different drugs: polymer (0.5, 1.0, w/v %) ratios. The characterization…

Exhaust gas distribution in street canyons is one of the important research subjects in urban air quality studies. Vehicle emissions are an important group of pollutants in urban areas. In this study, the dispersion of exhaust emissions from vehicles in canyon…

Dünyada enerji üretimi yapılan her yerde havayı kirleten maddeler atmosfere atılmaktadır. Özellikle yakma sistemlerinin baca ve egzozlarından çevreye yayılan bu kirleticiler insan sağlığını ve canlıların hayat şartlarını olumsuz yönde etkilemektedir. Yapılan b…

The purpose of the study is to investigate the effect of motor vehicle taxes on the amount of exhaust emissions (emissions) in EU and Turkey. Firstly the taxes on motor vehicles in EU and Turkey was explained in terms of the subject, the taxpayer and the ap…

A serial hybrid optical amplifier composing of two amplification stages of erbium-doped fiber (EDF) amplifier covered C-band window and Raman fiber amplifier (RFA) covered L band window demonstrated. In this paper, the optimizations were done to obtain the opt…

A universally applicable “optimal photobioreactor” design has yet to be established, as the success of such systems varies depending on the algal species used, environmental conditions, and intended applications. Meanwhile, the accelerating pace of climate cha…

Many well-known material structures, such as metals, ceramics or polymers, cannot meet all the technological demands. For this reason, there is ongoing research into new materials with advanced features. A composite material is consisting of at least two phase…

Current study is related with numerical simulation of a centrifugal pump impeller with the specific speed of nq=13. By the help of computational fluid dynamics (CFD) at different operating points, pump performance rsults (Head-Discharge graph) are obtained. Si…

Gelişen teknoloji ve artan nüfusun etkisiyle enerji tüketimi giderek artmaktadır ve bu durum tüm dünyada olduğu gibi ülkemizde de önemli bir problem olarak karşımıza çıkmaktadır. Fosil enerji kaynakları gün geçtikçe azalmaktadır ve bu nedenle araştırmacılar …

Evolution of EU road transport emission standards indicates that the limits have been reduced more than 90% in the last decades. However, nowadays, the urban populations in many developed countries are still suffering from urban transport sourced emissions. On…

Microalgae are recognized as environmentally sustainable and biologically renewable resources for the production of high-value products such as biomass, biofuels, dietary supplements, and pharmaceuticals. However, their large-scale cultivation is highly sensit…

Nanotechnology is the science of controlling materials at the atomic and molecular levels. With the use of nanomaterials for diagnostic and therapeutic purposes, the field of molecular nanotechnology has emerged, enabling nanoelectronic biosensors and individu…

The design of experiments is a highly effective offline quality improvement method to optimize the existing and new processes or products. In the literature, standard experimental situations have been paid a lot of attention. In a number of non-standard experi…

In this study, 0-12wt.% of Si3N4 or 0-30wt.% of SiC was added to the aluminum matrix by powder metallurgy method. Hence, the effect of reinforcement elements’s (SiC or Si3N4) amount on the mechanical properties was examined. Micro structures and crystal struct…

This study proposes a climate-adaptive framework for modular micro-living units as a construction-based response to growing urban challenges related to climate resilience, densification, and housing affordability. The design integrates prefabricated cross-lami…

Throughout history, earth as one of the most basic building materials of architecture, has stood out as a culturally and environmentally sustainable resource thanks to its local availability, compatibility with natural cycles and renewability. Increasing envir…

The devices developed in the field of organic electronics in recent years are on the technological applications and development of organic electronic devices using organic semiconductor films. The main applications of the organic electronic revolution are; Ele…

This paper explores the possibilities of architectural design to benefit human condition, which encompasses physical environment of a safe life during the climate change era and predicted disasters. The first part deals with the problem of natural hazards and …

Dünyada çevre ve insan sağlığı bilinci ile doğal ve yenilenebilir enerji kaynaklarından yararlanarak, amaca uygun ve zararsız alternatif ürünler geliştirmenin önemi her geçen gün artmaktadır. İnsan sağlığının önemi ve özenle korunması her geçen gün daha çok zo…

TiO2 films have been deposited by sol gel spin coating technique onto glass and p-Si substrates. TiO2 films were prepared using two different sols. The physical properties of the TiO2 films were examined based on two different parameters. In the first study,…
