The Solar Photovoltaic Thermal (PVT) system generates both electricity and thermal energy in a single system resulting in significant rooftop space savings and can be used for various domestic and industrial applications. A Hybrid PVT system is a combination of Solar PV and Solar thermal system Generates hot water and electricity from a single system [...]

The use of solar Photovoltaic (PV) technology is increasing rapidly owing to the huge demand for energy especially in the urban areas. Solar PV installations require approximately 8-10 m2 of land per kW of installation. In order to meet the energy demands of the urban dwellings, there is a dire need for a solution with [...]

CSIR-CEERI has developed a mercury-free plasma UV (MFP-UV) lamp with novel structural design and optimized gas mixtures that produces strong spectral bands peaking at wavelengths 253 nm and 172 nm along with a weak band peaking at wavelength 265 nm, which is highly useful for water sterilization. The features of the MFP-UV lamp are mercury [...]

Over 50 percent of Indians suffer from tooth decay problems and nearly 25 percent of them visit the dentist. Dental tourism forms 10 percent of the total Indian medical tourism which is projected to grow at 30 per cent to Rs 9500 crore by 2018. Therefore there is huge demand for Dental oral examination medical [...]

An AC-based GaN blue light-emitting diodes (LEDs) with different designs (series and Wheatstone Bridge configurations) were successfully fabricated and demonstrated at wafer and chip level under CSIR network (R-Nano) programme. In the first design, 42 micro-LED chips were connected in a series for a high voltage operation, where the size of each chip was ~ 250 [...]

MEMS-based gas sensors being miniaturised have various advantages such as low power consumption, robust and stable electrical properties. These gas sensors have three main components namely micro-heater, interdigitated electrodes and sensing film. Micro-heater as the important part of the gas sensor device decides the power consumption of the gas sensor. Metal oxide based gas sensing platform [...]

A MEMS-based bulk micromachined piezoresistive accelerometer was designed and fabricated. The accelerometer is a quad-beam suspended structure, which is realised by a combination of wet and dry bulk micromachining techniques. The fabrication process of the accelerometer is CMOS compatible. Image of the fabricated accelerometer is shown in Fig. 1. The accelerometer has been designed for low-g [...]
