We are experiencing an explosion in the amount of digital content that is being generated every minute and the need to store this content has seen the demand for data storage reach unprecedented levels. This has led to the emergence of the “Cloud” as the pre-eminent paradigm for data storage and represents a marked shift from how data used to be stored just a few years ago.

Graphene, emerging as a true 2-dimensional material, has received increasing attention due to its unique physicochemical properties (high surface area, excellent conductivity, high mechanical strength, and ease of functionalization and synthesis). Printed Electronic also is a new wave of large-area electronics and flexible electronics manufactured by printing technology. The fusion of these...

This research was focused in two parts, experimental results and regression model. First, the research was studied on the proportion of cylindrical length that affected to the separation efficiency using a 40 mm hydrocyclone. The effects of cylindrical lengths of 60, 80 and 100 mm were investigated. The tested suspension was the mixed of silica and water. The silica particles have an average...
Thailand is currently in the stage of moving forward in the area of humane science by reduce, refine and replacement of animals, knowing as the 3Rs principle, in research and development of consumer products. With this regard, the Thai Food and Drug Administration (FDA), Ministry of Public Health, has adopted ASEAN cosmetic directive for non-animal testing of cosmetics. Meanwhile, the use of...
With the increase of nano-consumer using nanomaterials, the potential exposure to nanomaterials have been raised. Therefore recently the human and environmental impacts of nanomaterials have emerged as an issue. However, there are no suitable methods to evaluate the cytotoxicity of nanoparticles based on high-throughput screening method. High-throughput approaches allow the bulk of the...
Nano information is crucial for nano safety along the life cycle of nanomaterials. Transparency on nano content offers advantages for producers, downstream users and consumers of nanoparticles. There are differences is the nano perception between different continents. Consumers in Asian countries like to buy nano products with nano particles because they appreciate the advantages of nano...
Nanomaterials have enormous economic potential for technical and medical applications due to their new properties acquired on the nanoscale. However, given multiple exposure pathways from the raw material production to the final product and its disposal, it is necessary to understand where and how nanomaterials can be released, and how this release can lead to exposure of workers, consumers...
A survey of 512 students from two local universities revealed that perception of nanotechnology regarding its importance to Thailand's economy and personal welfare was overall positive. Students especially 'agreed' or 'strongly agreed' with survey questions that focused on government support and regulation of nanomaterials and nano-labelling and were overwhelmingly in favor of developing a...
Taiwan Nanotechnology Program has been launched from 2003 up to now in which nano-EHS program remains one of the main projects collaborated by many different agencies, including Taiwan MOST, EPA, ILOSH, MOHW, BSMI, universities and research institutes (ITRI, NHRI etc.). Through inter-agency efforts, progress has been made in core facility establishment for nanomaterial characterization,...
Nanotechnology has been implemented in the construction industry and one application is the use of photocatalytic cement which is Portland cement containing titanium dioxide (TiO2) nanoparticles. Photocatalytic cement makes the surface white without the need of paint. TiO2 acts as a biocide making the surface selfcleaning.
However, TiO2 is a human carcinogen (Group 2B; IARC) and construction...
The National Nanotechnology Centre under the Ministry of Science, Technology and Innovation Malaysia is embarking a 5-year project on benchmarking studies for risk assessment of nano-based products. Four major activities have been outlined. First activity will look into the distribution of nano-based products in the local market and the nanomaterials involved. Data will be used to develop an...
A good form of teaching and learning approach for nanosafety related topics is the mse of games and entertainment values activities. According to experts much of the way we learn today is through the use of higher order skills. Games naturally support the form of education that requires ability to think through and solve complex problems, or interact critically through language or media. Game...
How we learn from occupational diseases induced by exposure to conventional particles and how we prevent diseases from new materials by bridging the above with human studies and experimental studies? Many studies focus on specific effects of particles to obtain the knowledge on safe by design, but also we should understand non-specific effects of particles. The idea of mixed-dust...
Abstract
Self-healing materials are a class of materials that can repair themselves. This feature is very interesting because it allows for saving resources to build new materials, saving energy need to make new materials, and finally reducing the amount of waste that can contaminate the environment.
In our research, we use the power of nanotechnology to tailor new materials that are useful...
Generally, Organic LEDs can be fabricated using either vacuum deposition or wet processes. It is well known that vacuum deposition can produce high efficiency Organic LEDs. Solution processable organic light emitting diode offers simpler, cheaper method of fabrication which is compatible with the roll-to-roll and inkjeting process. However, generally solution processable LED suffers from...
Self-assembly nanoparticle films from convective deposition using assistance of vibrated substrate can show optical diffraction in reflected mode, due to uniform high order surface structure. In this work, we investigated the optical diffraction from binary-nanoparticle films which were coated by two types of nanoparticle with different diameter i.e. 100 and 1000 nm of polystyrene and silicon...
Multiferroic materials, which exhibit both electrical and magnetic ferroic orders, have attracted much attention due to its potential application in electronics. Normally, the relation of both phenomena have to be analysed by several instruments. Here, optical-Kerr-effect properties of bismuth ferrite (100) thin film has been investigated. The Kerr rotation of light reflected from the...
Nanoparticles-based drug/gene delivery have been reported for potential therapeutic management of various ocular surface and corneal disorders [Kompella UB, et al., Nanomedicines for back of the eye drug delivery, gene delivery, and imaging. Prog Retin Eye Res. 2013;36:172-98]. In this study, we have examined penetration of mono-dispersed silica nanoparticles stained with Rhodamine B (RhB) and...
ABSTRACT
Surface modification methods are used in several industries as biomedical, textiles, microelectronics, bioprocessing, and food packaging. Most commercial polymers surface are inert and hydrophobic in nature, they must be modified or treated prior to covalent attachment with desired compounds on their surface. Surface modification technology as UV irradiation has been used to...
