We designed and built a combination of a scanning tunneling microscope ~STM! and a scanning electron microscope ~SEM! which is working under ultrahigh vacuum conditions ~base pressure typically 7 • 10 mbar!. The SEM is ideally used for surveying the sample and to control the STM tip positioning, while the STM extends the resolution range into the atomic scale. The design concept allows moving t...
introduction: the aim of this study was to evaluate the composite surface treated by different powers of erbium-doped yttrium aluminum garnet (er:yag) laser in comparison with bur preparation via scanning electron microscope. methods: fourteen composite resin blocks with 15× 10 × 10 mm dimensions were used in this study. the samples were divided to seven groups as follow: group 1 (power: 1 w, e...
Abbreviations: BOD: biochemical oxygen demand COD: chemical oxygen demand OD: optical density OW: optimized wastewater PNSB: purple non sulphur photosynthetic bacteria ROW:raw optimized wastewater RW: raw wastewater SCP: single cell protein SEM: scanning electron microscope SOW: sterile optimized wastewater SW: sterile wastewater TEM: transmission electron microscope TKN: total kjeldahl nitroge...
OBJECTIVES The aim of this study was to determine the apical surface characteristics and presence of dental cracks in single-rooted premolars, resected 3.0 mm from the root apex, using the Er: YAG laser, tungsten carbide bur, and diamond-coated tip, by scanning electron microscopy (SEM). EXPERIMENTAL DESIGN Thirty single-rooted premolar teeth were collected. The instrumented and obturated tee...
This study investigated the deformation effects of the interface between conventionally produced stainless steel X2crNi 19 11 and HIPed NiTI coating (Hot Isostatic Pressed). Near-equiatomic nickel-titanium alloy (NiTi) has many attractive material properties, such as pseudo-elasticity and shape memory effects, which result into beneficial engineering properties e.g. as cavitation resistant coat...
Laser Aided Manufacturing Process (LAMP) can be applied to repair steel die/molds which are currently repaired using traditional welding process in industry. In order to fully understand the advantages of laser deposition repair process over traditional welded-repair process, the mechanical properties such as tensile strength and hardness of H13 tool steel samples produced by these two processe...
STUDY ON VANADIUM CARBIDE COATING FORMATION ON AISI L2 STEEL BY THERMO-REACTIVE DEPOSITION TECHNIQUE
Abstract: The possibility of vanadium carbide coating formation on AISI L2 steel was studied in molten salt bath containing 33 wt% NaCl- 67 wt% CaCl2. In this research, the effects of time, temperature and bath composition on growing layer thickness were studied. The vanadium carbide coating treatment was performed in the NaCl-CaCl2 bath at 1173, 1273 and 1373 K temperatures for 3, 6, 9 hours a...
This paper contains data and supporting information of and complementary to the research article entitled "Effect of jar shape on high-energy planetary ball milling efficiency: simulations and experiments" (Broseghini et al.,) [1]. Calcium fluoride (CaF2) was ground using two jars of different shape (cylindrical and half-moon) installed on a planetary ball-mill, exploring different operating co...
In this research nanoparticles of Nickel (II) Chloride were synthesized and characterized using fourier transform infrared (FT-IR) spectra. Nanoparticles of Nickel (II) Chloride were prepared by using of ball mill device. A ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. In the researc...
background of the study: colorectal cancer (crc) which is the third most diagnosed cancer throughout the world is steadily rising in the asian countries with the incidence rates mimicking the western counterparts. the pre-neoplastic nature of the transitional mucosa (tm) adjoining crc lacks conclusive evidence so far. pertaining to this, the study of the mucus layer, the functional component of...
