Particleboard is not entirely a wood replacement but a particular material with its properties, making it more effective at different times than heavy or solid wood. The world’s biggest concern is environmental problems with formaldehyde as a particulate board binder that can lead to human carcinogenic agents. A cradle-to-gate life cycle assessment (LCA) of particleboard production was performed using openLCA software. The impact assessment was carried out according to the software’s features. This preliminary investigation aims to analyze the chemical composition of particleboard and identify its environmental impact. The Fourier-transform infrared spectroscopy (FTIR) system was used to track the functional group of aliphatic hydrocarbons, inorganic phosphates, and main aliphatic alcohols found in particleboards made in Malaysia. Based on the FTIR results, aliphatic groups were found in numerous aggravates that the spectroscopic infrared was likely to experience. The most important vibrational modes were C–H, at approximately 3000 cm−1, and –CH deformations around 1460 cm−1 and 1380 cm−1. Eight effect groups demonstrated that 100% of the input and all analyses produced the same relative outcome. The life cycle of a product is determined by pollution of the air, water, and soil. Thus, particleboard has a minimal impact on the environment, except for global warming.

Carbon fibre-reinforced polymer (CFRP) composite materials play an increasingly important role in modern manufacturing, and they are among the more prominent materials used in aircraft manufacturing today. However, CFRP is highly prone to delamination and other damage when drilled due to it being extremely strong with a good strength-to-weight ratio and high thermal conductivity. Because of this problem and CFRP’s growing importance in aircraft manufacture, research has focused on the entry and exit holes as indicators of damage occurrence during drilling of screws, rivets, and other types of holes. The inside of the hole was neglected in past research and a proper way to quantify the internal side of a hole by combining the entry and exit hole should be included. To fill this gap and improve the use of CFRP, this paper reports a novel technique to measure the holes by using the extension of the adjusted delamination factor (SFDSR) for drilling thick CFRP composites in order to establish the influence of machining input variables on key output measures, i.e., delamination and other damages. The experimental results showed a significant difference in interpretation of the damage during the analysis. Improvement was made by providing better perspectives of identifying hole defects.

The demand of a long life battery unit to supply the power for wireless application devices show significant grows. The radio frequency is one of the sources that can harvest the surrounding energy to a desired voltage due to availability to find everywhere with free cost. This paper presents a design of RF to DC conversion circuit for energy harvesting. The proposed circuit consists of rectifier, ring oscillator, charge pump and regulator is implemented in 0.13 μm CMOS technology. The rectifier is rectified the RF input signal to a DC voltage. The combination of charge pump and the ring oscillator act as a DC to DC converter to boost a low input voltage to higher output voltage. Finally the DC output voltage will be regulated to a desired 1.2 V DC. The simulations result shows that the RF signal of 900 MHz to 2400 MHz, -16.48 dBm is converted to DC regulated voltage of 1.25 V DC at 50 kΩ load.

In the present study, we synthesized nanometer-sized composite of silicon (Si) and chromium manganese disilicide ((Cr,Mn)Si2) with the eutectic composition. The appropriate Cr/Mn ratio and correct eutectic composition were examined. The n-type nanostructured phosphorous (P)-doped Si-Cr0.80Mn0.20Si2 eutectic alloy was successfully fabricated by melt-spinning. The ribbon-like samples were obtained with lamellar spacing range of 20–40 nm. The ribbons were then pulverized and sintered by spark plasma sintering with the size of the morphology change to about 100-200 nm. The thermal conductivity of sintered sample was reduced by 20-30% at room temperature, which results in increase of the dimensionless figure-of-merit value by 50%. The self-organizing structure refinement process, based on liquid quenching at the eutectic reaction, is considered to be an effective method to enhance the thermoelectric performance.

Dye sensitized solar cell (DSSC) is a third generation solar cell that is well known for its low cost, simple fabrication process and promised reasonable energy conversion efficiency. Basic structure of DSSC is composed of photoanode, dye sensitizer, electrolyte that is sandwiched together in between two transparent conductive oxide (TCO) glasses. Each of the components in the DSSC contributes important role that affect the energy conversion efficiency. In this research, the commonly used titanium dioxide (TiO2) photoanode has previously reported to have high recombination rate and low electron mobility which caused efficiency loss had been compared with the zinc oxide (ZnO) photoanode with high electron mobility (155 cm2V-1s-1). Both of these photoanodes had been deposited through doctor blade technique. The electrical performance of the laboratory based DSSCs were tested using solar cell simulator and demonstrated that ZnO is a better photoanode compared to TiO2 with the energy conversion efficiency of 0.34% and 0.29% respectively. Nanorods shape morphology was observed in ZnO photoanode with average particle size of 41.60 nm and average crystallite size of 19.13 nm. This research proved that the energy conversion efficiency of conventional TiO2 based photoanode can be improved using ZnO material.

Dye sensitized solar cell (DSSC) is a well-known photovoltaic device that is used for low power application. One of the main components for DSSC is semiconductor material photoanode which will provide the pathway for electron transportation and thus determine the energy conversion efficiency of the DSSC. The most commonly used material for the semiconductor photoanode is titanium dioxide (TiO2).TiO2is a semiconductor material with wide bandgap material that is existed in three crystalline phase; rutile, anatase and brookite. This paper emphasizes the best annealing temperature for commercialized TiO2, 98% anatase powder where the temperature varies from 300 oC – 600 oC. Through this research, the best annealing temperature for anatase TiO2photoanode is at 420 °C (0.094%) with the crystallite size of 18.76 nm and particle size of 19 nm that is favorable for the dye attached and thus enhances the energy conversion efficiency of the DSSC.

Nanostructuring is known to be an effective method to improve thermoelectric performance but, generally, it requires complex procedures and much labor. In the present study, self-assembled nanometer-sized composite structures of silicon (Si) and chromium disilicide (CrSi2) were easily fabricated by the rapid solidification of a melt with a eutectic composition. Ribbon-like samples were obtained with a dominant nanostructure of fine aligned lamellae with a spacing range of 20–35 nm. The thermoelectric power factor of the ribbon was observed to be 1.2 mW/mK2 at room temperature and reached 3.0 mW/mK2 at 773 K. The thermal conductivity was 65% lower than that of a bulk eutectic sample. The results suggest that this method is promising for fabricating an effective nanostructure for thermoelectric performance.

Dye sensitized solar cell (DSSC) is the third generation solar cell that consists of semiconductor electrode, dye, electrolyte and counter electrode. Among all of the components, dyes perform a primary role in absorbing solar energy and converting it to electrical energy. Therefore, the DSSC performance is absolutely depends on the type of dye sensitizer used. The traditional DSSC used Ruthenium (Ru) complexes as the sensitizer. However, Ru has several limitations due to high cost, rarity and complexity to be synthesized. Thus, in exchange to metal complex Ru dyes, current researches are focusing on natural dyes that are extracted from plants. This paper emphasizes on various researches which involved natural dye pigments; anthocyanin, chlorophyll and betalain. Based on the data comparisons, betalain pigments extracted from purple wild sicilian prickly pear dye has recorded the highest energy conversion efficiency of 2.06%. This has made the betalain pigments as a promising candidate for the best natural dye sensitizer, followed by anthocyanin and chlorophyll.

Dye sensitized solar cell (DSSC) is a promising candidate for a low cost solar harvesting technology as it promised a low manufacturing cost, ease of fabrication and reasonable conversion efficiency. Basic structure of DSSC consists of photoanode, dye, electrolyte and counter electrode. Photoanode plays an important role for a DSSC as it supports the dye molecules and helps in the electron transfer that will determine the energy conversion efficiency. This paper emphasizes the various improvements that had been done on the TiO2 and ZnO photoanode nanostructures synthesized through thermal method. For overall comparisons, ZnO nanoflowers photoanode had achieved the highest energy conversion efficiency of 4.7% due to its ability of internal light scattering that had increased the electron transportation rate. This has made ZnO as a potential candidate to replace TiO2 as a photoanode material in DSSC.

Solar cell is expanding as green renewable alternative to conventional fossil fuel electricity generation, but compared to other land-used electrical generators, it is a comparative beginner. Many applications covered by solar cells starting from low power mobile devices, terrestrial, satellites and many more. To date, the highest efficiency solar cell is given by GaAs based multilayer solar cell. However, this material is very expensive in fabrication and material costs compared to silicon which is cheaper due to the abundance of supply. Thus, this research is devoted to develop multilayer solar cell by combining two different layers of P-I-N structures with silicon carbide and silicon germanium. This research focused on optimising the intrinsic layer thickness, p-doped layer thickness and concentration, n-doped layer thickness and concentration in achieving the highest efficiency. As a result, both single layer a-SiC and a-SiGe showed positive efficiency improvement with the record of 27.19% and 9.07% respectively via parametric optimization. The optimized parameters is then applied on both SiC and SiGe P-I-N layers and resulted the convincing efficiency of 33.80%.

Ga1-xInxP composition has been applied to the top cell of multi-junction GaInP/GaAs based solar cell and currently have achieving a conversion efficiency of more than 46%, however its capability is unclear. We performed an analysis using Silvaco simulation method to evaluate the effect of In and the substitution was made to the Ga1-xInxP for the range of x from 0 to 1. We found that the highest efficiency recorded was 17.66% when the composition of Indium was x=1. The efficiency has been increasing about 11.71% from x=0 to x=1 In content. As the composition of In raised, the value of efficiency and short circuit current density, Jsc also become higher (13.60 mA/cm2) by having a greater photon absorption in a wider band gap energy. In addition to that, Voc, Pmax, Vmax, Imax and fill factor was measured to be 2.15 V, 2.44 mW/cm2, 2.0 V, 1.22 mA/cm2 and 83.34 respectively. In conclusion, this study confirms that the existence of In in Ga1-xInxP improves the solar cell efficiency by gaining a higher energy gap and producing more electrons for best achievement in multilayer solar cell applications.

Dye sensitized solar cell has been emerged as one of the most promising candidates for photovoltaics applications in good quality of their low manufacturing cost and impressive conversion energy. Titanium dioxide (TiO2) which is used as photoanode in the market has the advantage of wide bandgap energy but low in electron mobility (~10 cm2/(V.s)). Ruthenium in the other hand, as the dye sensitizer is a rare noble metal and harmful to human health. Thus, this article reveals the performance of photo-to-electric conversion efficiency with the usage of Zinc Oxide as photoanode with higher electron mobility (155 cm2/(V.s)) compared to TiO2 utilizing three natural fruit dyes of Prunus domestica, Magnifera indica and Citrus limon. ZnO and TiO2 photoanodes were fabricated using sol gel and dr blade method respectively. The morphology of the photoanodes were characterized using Scanning Electron Microscope and the efficiency of the complete DSSC with all different fruit dyes were characterized using Semiconductor Parametric Analyzer. The different property of electron mobility photoanodes effect in DSSC proved to give better performance with the photoconversion efficiency of 3.082% using ZnO with Prunus domestica dye. This article also reveals that pH indicator does not affect the selection and the performance of DSSC.

Wireless power transfer (WPT) is a device that transmits electrical energy from a power unit to an electrical load through the air wirelessly or without the interconnection of any conductors. The designs of current WPT are quite large and inappropriate for many applications, especially for electronic devices. The small scale (mid-range WPT) with 1 meter distance was investigated to develop a wirelessly transmitted energy for the use of electronic devices, particularly to charge portable devices. The distance of a mid-range WPT can be increased by placing the resonators between the transmitter and receiver to achieve the 1-meter distance of the WPT. The power transfer efficiency (PTE) was significantly enhanced when the resonators was placed. The high efficiency was maintained due to the increasing distance of the WPT. As a result, more power can be transmitted from transmitter to the receiver respectively.
