The ability of biofilms to form on a range of materials (cementious backfill (Nirex Reference Vault Backfill (NRVB)), graphite, and stainless steel) relevant to potential UK intermediate level radioactive waste (ILW) disposal concepts was investigated by exposing these surfaces to alkaliphilic flocs generated by mature biofilm communities. Flocs are aggregates of biofilm material that are able ...

Objective. The purpose of this study was to analyze the absorption of metal ions released from stainless steel crowns by root surface of primary molars. Study Design. Laboratory research: The study included 34 primary molars, exfoliated or extracted during routine dental treatment. 17 molars were covered with stainless-steel crowns for more than two years and compared to 17 intact primary molar...

The present work intends to evaluate the use of immediate loaded orthodontic screws in a growing model, and to study the specific bone response. Thirty-two screws (half of stainless steel and half of titanium) were inserted in the alveolar bone of 8 growing pigs. The devices were immediately loaded with a 100 g orthodontic force. Two loading periods were assessed: 4 and 12 weeks. Both systems o...

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...

S. Epidermidis is among the most frequently isolated microorganisms found in -infection related to implanted devices and the formation of biofilm will be more resistant compared to the planktonic form. This study was carried out to determine the effect of coating on stainless steel orthopaedic implants surfaces with cinnamon oil and chitosan as bioadhesive to prevent biofilms formation of S. Ep...

BACKGROUND Self-expanding metal and plastic esophageal stents (SEMS and SEPS, respectively) are used in conjunction with chemoradiation for palliation of malignant dysphagia. To date, the dosimetric effects of stents undergoing proton radiotherapy are not known. STUDY AIM To investigate the proton radiotherapy dose perturbations caused by esophageal stents of varying designs and materials und...

Article history: Received: 23.12.2013. Received in revised form: 15.01.2014. Accepted: 15.01.2014. Subcritical austenite reverse transformation quenching was used to improve the mechanical properties of 30CrMnSi steel, and the microstructure and mechanical properties of the samples were analyzed by subcritical austenite reverse transformation quenching. Experimental results show that subcritica...

The aim of this study was to evaluate the frictional force between orthodontic brackets and archwires. The differences in magnitude of the frictional forces generated by ceramic brackets, ceramic brackets with metal reinforced slot, and stainless steel brackets in combination with stainless steel, nickel-titanium, and beta-titanium orthodontic archwires were investigated. Brackets and wire were...

Understanding adsorption phenomena on stainless steel surfaces is of important because stainless steel is widely used from food and dairy to pharmaceutical industries. Protein adsorption and fouling undermines the efficiency of stainless steel process equipments and leads to an increase in operational costs due to regular cleaning. For this reason, adsorption of milk proteins on stainless steel...

Microelectrodes implanted in cortical tissue have been shown to effectively send and record electrical brain signals. The limitation encountered in the past is the robustness of these electrodes. New flexible electrodes are being developed to solve this problem, but electrochemical (EC) measurements are a required step in the characterization of these microelectrodes before they can be implante...
