Publication Metadata only Investigation of industrial tea-leaf-fibre waste material for its sound absorption properties(ELSEVIER SCI LTD, 2009) KÜÇÜK, HALUK; Ersoy, Sezgln; Kucuk, HalukThe sound absorption of an industrial waste, developed during the processing of tea leaves has been investigated. Three different layers of tea-leaf-fibre waste materials with and without backing provided by a single layer of woven textile cloth were tested for their sound absorption properties. The experimental data indicate that a 1cm thick tea-leaf-fibre waste material with backing, provides sound absorption which is almost equivalent to that provided by six layers of woven textile cloth. Twenty millimeters thick layers of rigidly backed tea-leaf-fibres and non-woven fibre materials exhibit almost equivalent sound absorption in the frequency range between 500 and 3200 Hz.

Its sound absorbing characteristic was investigated in the impedance tube, according to transfer function method. Measurements show that HIPS ratios have effect on the absorption performance of the blend because of their microstructures and features. The structure and properties of the blend is characterized using a scanning electron microscopy (SEM). Furthermore, styrene ethylene butadiene styrene and high impact polystyrene polymer blend was subjected to examinations to obtain their hardness and Izod impact strength. When the sound absorption characteristics of the materials are examined, a unsteady behaviour is observed up to the level of 1600 Hz. It is determined that sound absorption characteristics of all materials increase after this point. A high and steady behaviour is observed, particularly after 4800 Hz.Publication Metadata only The fundamentals of metal-matrix composites(NOVA Science Publishers Inc., 2022-01-01) ERSOY, SEZGİN; Ersoy S. (Editör)Developing production technology tries to respond to human needs. Meeting these needs requires the development of new products or an increase in the supply of raw materials. Although polymer-based, recycled, and natural resources are used as raw materials, it does not reduce the importance of metal-based structures. However, there is a need to use these metal-based materials at lower costs or to improve their existing properties. This book offers relational studies to these issues.Publication Metadata only Advances in tannic acid-incorporated biomaterials: Infection treatment, regenerative medicine, cancer therapy, and biosensing(Elsevier B.V., 2022) ERSOY, SEZGİN; Bigham A., Rahimkhoei V., Abasian P., Delfi M., Naderi J., Ghomi M., Dabbagh Moghaddam F., Waqar T., Nuri Ertas Y., Sharifi S., Rabiee N., Ersoy S., Maleki A., Nazarzadeh Zare E., Sharifi E., Jabbari E., Makvandi P., Akbari A.Polyphenol-based materials have attracted wide-spread interest from academic and industrial communities because of their unique structure and physicochemical properties. Tannic acid (TA), as a polyphenolic phytochemical with high level of galloyl groups, interacts with various substances (proteins, polysaccharides, and metals) through several modes including hydrogen bonding, hydrophobic and electrostatic interactions. Such hybrid or hybrid-like systems allow the preparation of various advanced materials with promising applications in medicine. In this review, we highlight the recent advances of TA-incorporated materials in medical applications including drug delivery, tissue engineering, treatment of infections, cancer therapy and biosensing. We believe that this review provides further investigation and development of TA as a promising natural compound to design new versatile architectures in the field of materials science. © 2021 Elsevier B.V.Publication Metadata only Deep learning and object detection practices in agriculture(Lambert Publishing, 2022-01-01) ERSOY, SEZGİN; Ersoy S., Güllü A., Öztürk N.Publication Metadata only Investigation of Sound Absorption and Impedance Ratio of SBR/HIPS Polymer Blends(TAYLOR & FRANCIS INC, 2012) TAŞDEMİR, MÜNİR; Ulug, Ebru; Tasdemir, Munir; Ersoy, SezginA sound absorption material composed of styrene butadiene rubber and high impact polystyrene blend has been developed. With the increased amount of HIPS in SBR/HIPS polymer blends, hardness and Izod impact strength values of the resultant material increased. Sound-absorbing characteristics of SBR/HIPS polymer blends were investigated in the impedance tube, according to transfer function method. The sound absorption coefficients are generally above 0.2 with the maximum of 0.5. It reveals that soft blends have good sound absorption ability in 4000 Hz frequency range. For all groups the least sound absorption rate was seen in the area of 315 Hz at the rate of 0.01. With the increase of frequency for all groups impedance ratio decreased. With addition of SBR rubber to the HIPS, the adhesion and distribution of the present phases were considerably enhanced as well.Publication Metadata only Metal screw design for additive manufacturing techniques(NOVA Science Publishers Inc., 2022-08-01) ERSOY, SEZGİN; Ersoy S., Ekinci B.Publication Metadata only Investigation of new education methods using applied mechatronics(Nova Publisher, 2011-01-01) ERSOY, SEZGİN; ERSOY S.Explores the broad spectrum of science education with a focus on such topics as mechatronics, a multidisciplinary field combining mechanical engineering, electronics and computer technology; science education through research, science and technology museums as places for critical thinking.
