This is a pilot project undertaken by the UG and PG students of the Department of Physics, St. Xavier’s College (Autonomous), Kolkata under the supervision of Dr. Suparna Roychowd- hury and Dr. Shibaji Banerjee and with the assistance of Mr. Bappaditya Manna, Technical Officerof Father Eugene Lafont Observatory (FELO) on building a low-cost high-frequency radiotelescope using Arduino.This paper presents the design of the smallArduino-based radio telescope recently developed by the group to observe radio emission at high frequencies (12-18GHz)and the initialobservations including detection of geostationary andnon-geostationary satellites.Preliminary results demonstrate the effectiveness of this Arduino-based radio telescope in the eraof large radio telescopes that are inaccessible to students. As the radio telescope operates in ahigh-frequency range, it is easier to observe in city areas where Radio Frequency Interference(RFI) is a significant issue. The system can be pointed either manually or using a computerized mount to any radio source and data can be collected from a satellite finder as well asfrom Arduino micro-controller. This system can be used for a basic understanding of radioastronomy and for training purposes for University and College students at a very lowcost. Further, we would also like to extend this to a two-element radio interferometer andundertake interferometric observations of astronomical radio sources in future.

In response to the growing demand for electronics, scientists are actively investigating alternative non- conventional, bio-compatible electronic materials suitable for electronic and optoelectronic device applications.This study focuses on enhancing the photoconductivity and photosensitivity of a beetroot (BR) dye-based Schottky device through the incorporation of Titanium dioxide (TiO2) nanoparticles. To achieve this, ITO(Indium tin oxide)/BR/Al (Aluminium) and ITO/BR+TiO2/Al devices were fabricated through the spin coating technique, and their light-induced charge transport properties were examined.The thin films were also characterized through UV-Vis and FESEM analyses. Initial measurements of photoconductivity, sensitivity, and photoresponsivity of the device yielded unsatisfactory results, indicating the need for improvement to enable effective device applications. To address this, we incorporated Titanium dioxide nanoparticles with the dye by making nano-composite, leading to a remarkable enhancement in photoconductivity, increasing from 2.78×10-8 S/m to 1.75×10-7 S/m, and a significant boost in photosensitivity, rising from 1131.03 to 2157.67.Furthermore, we estimated other light transport properties, including diffusion length, transit time, and effective mobility, for a comprehensive analysis of the device's performance. These additional parameters also exhibited notable enhancements in the presence of TiO2 nanoparticles.This research contributes valuable insights into the application of TiO2 nanoparticles in enhancing the performance of organic- based optoelectronic devices, and it offers potential avenues for further exploration and refinement of bio-compatible electronic materials in electronic and optoelectronic applications.

The Jaynes-Cummings Model has been a standard paradigm for light-matter interaction for a few decades. The Lie algebraic properties of the model permits us to solve for the time evolution of a coupled radiation-matter system. In this work we study the model with linear time dependence and show that it is analytically solvable. We use our results to calculate the Mandel Q-parameter which shows how nonclassical the resulting radiation state is.

Keywords: Jaynes-Cummings Model, Mandel Q-parameter

The onset of quantum fever in India is ever growing and fascinating. Being a common chapter to subjects like Computer Science, physics and engineering, the basics of so called “quantum advantage” or “quantum supremacy” foundation is being laid. The usage of quantum computers is keeping on increasing and is no more a theoretical utopia since real quantum computers are now available which have been proved to serve results faster than regular modern-day computers. The workings demand well established such as Shor’s and Grover’s Algorithms. This paper is a short epiphany of the degree and heights of usage of quantum computers in the field of machine learning. An exponential rise has taken place in understanding machine learning through quantum computing due to its vast ranges through which it can be applied. For instance, if a classical artificial neuron can produce results up to N dimensions, then a corresponding quantum perception has the ability of processing results in about 2N dimensions. This paper rather excavates the above-mentioned possibilities and tries for understanding new prospects, keeping in mind that quantum machine intelligence will probably be the pioneering research field in the years to come.

Nanotechnology is the investigation of matter at the molecular and atomic levels. It identifies and discovers the beneficial features at the nanoscale level. There are numerous applications of nanotechnology in modern science. Medicinal field has great impact of modern nanoscience. Nano disks, high density lipoprotein nanostructures, and gold nanoparticles are different example of nanotechnology applied in drug delivery system. The growing discipline of this nanotechnology fulfilled the demand for innovative methods in the detection and treatment of cancer. With the help of this advanced technology several functional molecules can be conjugated simultaneously such as tumor-specific ligands, antibodies, anticancer drugs, and imaging probes etc. Nanoparticles are biocompatible and biodegradable in nature. They act as a carrier, which target particular sites of cancer cell. Since, nanoparticles are 100-1000 times smaller than cancer cells, they can readily pass through leaky blood vessels. They can easily interact with tumor-specific proteins both on the outside and inside of cancer cells. This advance nanotechnology has brought a new hope for developing treatment of cancer therapy. In this article, we highlighted a review on the recent applications of nanoscience in enhancing immunotherapy and the treatment of cancerous cells.
