Abstract: This paper presents an overview of the work done on graphene in recent years. It explains the preparation techniques, the properties of graphene related to its physio-chemical structure and some key applications. Graphene, due to its outstanding electrical, mechanical and thermal properties, has been one of the most popular choices to develop the electrodes of a sensor. It has been used in different forms including nanoparticle and oxide forms. Along with the preparation and properties of graphene, the categorization of the applications has been done based on the type of sensors. Comparisons between different research studies for each type have been made to highlight their performances. The challenges faced by the current graphene-based sensors along with some of the probable solutions and their future opportunities are also briefly explained in this paper.

Abstract:  Abstract—Nanotechnology is not new and is known to exist for ages, be it in the sword of tipu sultan or in the windows of the medieval churches in Europe. A common question in the minds of all of us living in today's world is about how the mechanism of nanotechnology can be used in the healthy compatibility with the constructional structures like that of massive buildings and bridges, which have been thought to encroach upon huge masses of land, leading to the destroying of homes of wildlife and putting pressure in the limited reserves of energy. This review paper focuses on the sustainable usage of nano based materials like carbon nanotube, electrochromic windows, nanoclays, sandvik nanoflex™, nanowires, titanium dioxide, nanoceramic coating, nanocrystalline materials, nanosilica, nanocomposites, MMFX2 steel, nanometals, nanofibres, nanomyte™ mend MW, nanocement, which could be used for providing singular or multiple functions of potential reinforcement, corrosion resistance, insulation, fire protection, temperature resistance, reducing air conditioning loads, pollution control, UV ray absorption, lighting, when used as a part of building materials.

TL;DR: The novelty of this research will help in fabrication of microbolometers at oblique angles to optimize the absorbed power.
Abstract: The literature segment of this paper delves into the enhanced mathematical model that is used to calculate the total electric and magnetic field for light ray's incident at oblique angles varying from 1–89 degrees for s and p polarizations in sensor structure followed by the calculation of fractional reflected and absorbed power. A brief description of the sensor structure followed by validation of the mathematical model and a tabular summarization of the maximum power reflected and absorbed at respective angles of incidences for the wavelength range of 5–14 μm is done. The novelty of this research will help in fabrication of microbolometers at oblique angles to optimize the absorbed power.

TL;DR: In this paper, a band-stop frequency selective surface (FSS) with targeted operation in the X-band (7~11.2 GHz) was designed, and liquid metal was embedded in PDMS microfluidic channels replicated from a deep etched Si mold.
Abstract: We report the design, fabrication, and characterization of PDMS encapsulated physically flexible (bendable, foldable) gallium-based liquid metal band-stop frequency selective surface. A band-stop frequency selective surface (FSS) with targeted operation in the X-band (7~11.2 GHz) was designed. Liquid metal was embedded in PDMS microfluidic channels replicated from a deep etched Si mold. Ultra-low pressure (5.75 x 10-6 Torr) vacuum at cryogenic temperatures (10 K) was employed for clean encapsulation of liquid metal. An array of 5 x 5 FSS has been fabricated. Characterization of the fabricated FSS was carried out in a waveguide environment. The S-parameter values of the simulated and measured band-stop FSS response showed an excellent agreement.

TL;DR: The two-step solution-phase reactions to form hybrid materials of Mn(3)O(4) nanoparticles on reduced graphene oxide (RGO) sheets for lithium ion battery applications should offer a new technique for the design and synthesis of battery electrodes based on highly insulating materials.
Abstract: We developed two-step solution-phase reactions to form hybrid materials of Mn3O4 nanoparticles on reduced graphene oxide (RGO) sheets for lithium ion battery applications. Mn3O4 nanoparticles grown selectively on RGO sheets over free particle growth in solution allowed for the electrically insulating Mn3O4 nanoparticles wired up to a current collector through the underlying conducting graphene network. The Mn3O4 nanoparticles formed on RGO show a high specific capacity up to ~900mAh/g near its theoretical capacity with good rate capability and cycling stability, owing to the intimate interactions between the graphene substrates and the Mn3O4 nanoparticles grown atop. The Mn3O4/RGO hybrid could be a promising candidate material for high-capacity, low-cost, and environmentally friendly anode for lithium ion batteries. Our growth-on-graphene approach should offer a new technique for design and synthesis of battery electrodes based on highly insulating materials.

TL;DR: A brief insight into the materials and basics of sensors (methods of transduction, molecular recognition, and amplification) is provided followed by a comprehensive and critical overview of the disposable sensors currently used for medical diagnostics, food, and environmental analysis.
Abstract: Disposable sensors are low-cost and easy-to-use sensing devices intended for short-term or rapid single-point measurements. The growing demand for fast, accessible, and reliable information in a vastly connected world makes disposable sensors increasingly important. The areas of application for such devices are numerous, ranging from pharmaceutical, agricultural, environmental, forensic, and food sciences to wearables and clinical diagnostics, especially in resource-limited settings. The capabilities of disposable sensors can extend beyond measuring traditional physical quantities (for example, temperature or pressure); they can provide critical chemical and biological information (chemo- and biosensors) that can be digitized and made available to users and centralized/decentralized facilities for data storage, remotely. These features could pave the way for new classes of low-cost systems for health, food, and environmental monitoring that can democratize sensing across the globe. Here, a brief insight into the materials and basics of sensors (methods of transduction, molecular recognition, and amplification) is provided followed by a comprehensive and critical overview of the disposable sensors currently used for medical diagnostics, food, and environmental analysis. Finally, views on how the field of disposable sensing devices will continue its evolution are discussed, including the future trends, challenges, and opportunities.
