“…Energy dispersive X‐ray spectrometry (EDXRF) and Raman spectroscopy are two analytical techniques that offer several advantages in studies regarding dentistry application . Both are non‐destructive analytical techniques, which allow the analysis of the same sample before and after bleaching ( self‐control measurements) . Moreover, analysis can be performed in short periods of time and are highly sensitive and require minimal preparation of the samples .…”

“…Both are non‐destructive analytical techniques, which allow the analysis of the same sample before and after bleaching ( self‐control measurements) . Moreover, analysis can be performed in short periods of time and are highly sensitive and require minimal preparation of the samples . This way, it is possible to study changes in elemental and molecular content, either in the hydroxyapatite matrix or in trace elements present in the teeth, after successive applications of bleaching product, exceeding the recommendations of the manufacturer …”

The purpose of this in vitro study was to assess whether the mineralization degree and elemental content in tooth enamel are altered when bleaching the teeth with two different over-the-counter bleaching gels, exceeding the recommendations of the manufacturer. In order to perform this evaluation, 12 healthy teeth were used, six samples were treated with Teeth Whitening Home Kit, and the other six samples were treated with WHITE! (Bingo-UK) bought in online shopping sites, for the period of 39 days. The pH of each product and the elemental content of each sample, before and after, were obtained by energy dispersive X-ray spectrometry and phosphate (PO 4 3-) profile was evaluated with Raman spectroscopy. Data was analyzed accordingly to a preestablished plan with a mixed-model ANOVA for repeated measures, significance was set at 5%. Both products were markedly acidic and below enamel critical level of 5.5. Moreover, seven days after treatment, demineralization was significant, wherein at the end of the study the degree of demineralization seems to be permanent.

“…The power source for electric engines is the main difference between these technologies. In this context, HEB employs both an internal combustion engine (ICE) and an electric motor (EM) to provide wheels with traction power [18]. The EM of FCEB is powered by a fuel cell technology that converts hydrogen and oxygen by applying a pair of redox reactions into electricity, water, and heat [19][20][21].…”

Electric Buses in Malaysia: Policies, Innovations, Technologies and Life Cycle Evaluations

et al. 2021

View full text Add to dashboard Cite

A large-scale adoption of electric buses (EBs) is a promising solution to mitigate greenhouse gas emissions from the transportation sector. In the upcoming decades, the development of EB technologies will be initiated worldwide, including in Malaysia. Government policies to support EB deployments have been widely established. Therefore, Malaysia’s National Automotive Policy has stated a roadmap of policies to promote a national groundwork accordingly. Following the elaboration of Malaysia’s goals for EBs deployments by 2014 and 2020, there are crucial associated topics for EBs implementation, including EB innovations and technologies adoption. This study presents a deep discussion about the groundwork of EB innovations that have been initiated in Malaysia to meet the roadmap targets. This paper also comprehensively reviews the technical specifications of EB innovation technologies, including Electric Bus Innovation Malaysia, Malaysia Automotive Institute, and Go Auto prototypes. In addition, this study outlines the EB technologies that have been launched in three states in Malaysia, known as Putrajaya, Melaka, and Sarawak. Furthermore, a generic framework for life cycle assessments of EB is presented, focusing on the economic and environmental impacts. This framework provides the necessary groundwork for further studies on charging infrastructure requirements.

“…In this work, we will focus on the comparison of the inorganic content and trace element determination before–after bleaching using commercially available products accordingly to manufacturer's instructions. To perform this analysis, we relied on the capabilities of energy dispersive X‐ray fluorescence technique to quantify trace element changes in tooth composition …”

Assessment of teeth elemental content usingμ-EDXRF: effects by in-office and at-home bleaching products

et al. 2014

The purpose of this in vitro study is to assess whether the elemental content of tooth enamel is altered when bleaching the teeth with bleaching gel. Because of tooth bleaching growing popularity and to match the public demands, manufacturers increased the range of bleaching products available, changing its presentation, techniques and concentration of active principles. This way, two different bleaching products were compared, one for in‐office and another for domestic use. In order to perform this evaluation, sound vestibular surfaces of anterior healthy teeth, extracted for periodontal or orthodontic reasons, were treated with the bleaching products accordingly to manufacturer instructions. Spectra were acquired using the M4 Tornado μ‐XRF setup, and quantitative calculations were performed using fundamental parameter method to determine the elemental composition of the analyzed samples before and after treatment. No significant statistical differences in the mineral content of the analyzed teeth were obtained. Copyright © 2014 John Wiley & Sons, Ltd.
