İşitsel peyzaj kavramı; mimari tasarım sürecinde, stüdyo tasarım sürecinin yapı sökümüyle yapılan deneyler ve yenilikçi tasarım çözümleri için yeni olanaklar yaratabilir. Algı önceliklerini değiştirmek (ses algısını görsel algıya tercih etmek) tasarım hakkında yeni düşünme ve bağ kurma biçimlerinin oluşması için yeni olasılıklar sağlayabilir. 2015 güz dönemi Anadolu Üniversitesi, Mimarlık Bölümü'nde, Mimari Tasarım Stüdyosu V dersimizde bu yaklaşım ve süreç deneyi gerçekleştirilmiştir. Yirmi üç kişilik öğrenci grubuna, önceden belirlenmiş kentsel alanların altı farklı, on beş dakikalık, binaural ses kayıtları, tek ve temel tasarım verisi olarak dağıtılmıştır. Öğrencilerden bu kayıtları dikkatli bir şekilde ve tekrar tekrar dinlemeleri; topoğrafya, yapı yoğunluğu, iklim koşulları, kullanıcıların demografik ve sosyo-ekonomik strüktürünü belirlemeleri, ve zaman alanına ait çıkarımlarda bulunmaları beklenilmiştir. Sonrasında, sadece duydukları ardından yarattıkları bu kendi kentsel alanlarına ait, ana tasarım problemini belirlemek üzere çalışmışlardır. Bu mimari tasarım stüdyo eğitimi denemesini önererek biz, temel maddesiz mimari elemanlardan olan sesin, yeni stüdyo ve tasarım süreçlerindeki etki ve olanaklarını araştırmaktayız.

“…Although Pd is a good electrocatalyst for EOR [31], its performance can be further enhanced by changing its size, morphology and the supporting substrate [31][32][33][34]. Carbon materials have long been used to support metal catalysts because of their inertness to chemical reactions, resistance to corrosion, large surface area and cost-effectiveness [35][36][37]. Various carbon-based nano-or micro-materials, such as carbon nanotube (CNT) [29,38], graphene or graphene oxide [39][40][41][42][43], carbon microspheres [44] and helical carbon nanofibers [45], have been used as Pd-based catalyst supports to increase its catalytic activity and efficiency.…”

“…Interestingly, the removal of the organic contaminants may increase hydrophilicity of the electrode surface and allow the easy access of metal ions. Adding oxygen species to the surface of carbon-based electrodes can further enhance the surface adsorption of metal ions [35,36], leading to the enhancement of chemical deposition and loading of Pt-Ru on the graphite nanofibers [63], and the improvement of electrodeposition and even distribution of gold nanoparticles on CFP [64]. Based on these observations, the development of a highly efficient electrode for DEFC by direct electrodeposition of Pd on the oxygen plasma-treated CFP was proposed.…”

In this study, a highly efficient carbon-supported Pd catalyst for the direct ethanol fuel cell was developed by electrodepositing nanostructured Pd on oxygen plasma-treated carbon fiber paper (Pd/pCFP). The oxygen plasma treatment has been shown to effectively remove the surface organic contaminants and add oxygen species onto the CFP to facilitate the deposition of nano-structured Pd on the surface of carbon fibers. Under the optimized and controllable electrodeposition method, nanostructured Pd of ~10 nm can be easily and evenly deposited onto the CFP. The prepared Pd/pCFP electrode exhibited an extraordinarily high electrocatalytic activity towards ethanol oxidation, with a current density of 222.8 mA mg−1 Pd. Interestingly, the electrode also exhibited a high tolerance to poisoning species and long-term stability, with a high ratio of the forward anodic peak current density to the backward anodic peak current density. These results suggest that the Pd/pCFP catalyst may be a promising anodic material for the development of highly efficient direct alcohol fuel cells.

“…Palladium on carbon is an important class of catalyst, which can be used in several industrial chemical processes including hydrogenation, dehydrogenation, hydrogenolysis, hydro-dechlorination, nitroarenes reduction, and C-C coupling [4][5][6]. It is well known that the activity and selectivity of the Pd-based catalysts supported on carbons, either Pd/C or Pd(OH) 2 /C, strongly depend on the preparation methods, the physicochemical properties of Pd particles, such as size, morphology, and dispersion of Pd species, and the nature and structure of carbon supports, involving porous structures and surface properties [2,[7][8][9]. There are two main general routes for the preparation of Pd-based catalysts on carbons: the ion exchange and the deposition-precipitation methods.…”

The influence of the surface chemical properties of the carbon support on the Pd dispersion, activity and stability of Pd(OH)2/C catalyst for the hydrogenolytic debenzylation of tetraacetyldibenzylhexaazaisowurtzitane (TADB) was studied in detail. The flowerlike nanosheet carbon material (NSC) was chosen as the pristine support, meanwhile chemical oxidation with nitric acid and physical calcination at 600 °C treatments were used to modify its surface properties, which were denoted as NSCox-2 (treated with 20 wt% HNO3) and NSC-600, respectively. The three carbon supports and the corresponding catalysts of Pd/NSC, Pd/NSC-600, and Pd/NSCox-2 were characterized by scanning electron microscope (SEM), transmission electron microscopy (TEM), nitrogen sorption isotherm measurement (BET), powder X-ray diffraction (XRD), Raman spectra, X-ray photoelectron spectra (XPS), temperature-programmed desorption (TPD), temperature-programmed reduction (H2-TPR), thermogravimetric analysis (TG), and element analysis. The debenzylation activities of Pd/NSC, Pd/NSC-600, and Pd/NSCox-2, as well as the three catalysts after pre-reduction treatment were also evaluated. It was found that the activity and stability of the Pd(OH)2/C catalysts in the debenzylation reaction highly depended on the content of surface oxygen-containing groups of the carbon support.
