In this growing age of clean energy and the use power storage to circumvent traditional fossil fuel technologies, batteries greater capacity, are increasingly becoming indispensable. New chemistries being developed increase capacity lithium ion develop beyond Lithium ion. Promising high cathodes anodes however their large-scale deployment is hindered due safety concerns. review, we will summarize state art safety, highlight current challenges outline most advanced features that may be...
Sulfur remains in the spotlight as a future cathode candidate for post-lithium-ion age. This is primarily due to its low cost and high discharge capacity, two critical requirements any material that seeks dominate market of portable electronic devices, electric transportation, electric-grid energy storage. However, before Li–S batteries replace lithium ion batteries, several technical challenges need be solved. Among these are polysulfide containment, increase sulfur loading (which must ≥4–6...
Hierarchical material nanostructuring is considered to be a very promising direction for high performance thermoelectric materials. In this work we investigate thermal transport in hierarchically nanostructured silicon. We consider the combined presence of nanocrystallinity and nanopores, arranged under both ordered randomized positions sizes, by solving Boltzmann equation using Monte Carlo method. show that nanocrystalline boundaries degrade conductivity more drastically when average grain...
Boundary scattering in hierarchically disordered nanomaterials is an effective way to reduce the thermal conductivity of thermoelectric materials and increase their performance. In this work we investigate transport silicon based nanostructured presence nanocrystallinity nanopores at range 300 K 900 using a Monte Carlo simulation approach. The follows same reduction trend as pristine material. We show, however, that relative stronger with temperature nanocrystallinity, consequence wavevector...
We performed a comprehensive multi-scale phonon-mediated thermal transport study of nano-porous silicon (np-Si) films with average porosities in the range φ = 30%–70%. This depth-resolved characterization involves combination optical methods, including femtosecond laser-based time-domain thermo-reflectance (TDTR) MHz modulation rates, opto-thermal micro-Raman spectroscopy, and continuum laser wave-based frequency domain (FDTR) kHz rates probing depths studied samples over 0.5–1.2, 2–3.2,...
Nanotechnology, which is being employed in all areas of technology, also finds application the sector forensics. It evident that utilization this technology will help criminologists to solve criminal mystery with greater accuracy and pace. Fingerprinting deoxyribose nucleic acid (DNA) analysis, forensic material testing, etc., are some technical zones invaded by nanoscience. This a brief review about applications nanotechnology provides insight future prospects amalgamation technologies,...
The objective of the present invention is to develop an ultrasensitive technique for electro analysis rape drug. A paper chip (EμPADs) was developed using nanocrystals (Nanocrys) graphene-oxide and zeolites (Zeo-GO). Nanocrys modified EμPAD showed wide linear range 0.001 - 5 nM/ml low detection limit 0.00002 nM/ml. sensor tested in real time samples like alcoholic non-alcoholic drinks found good correlation (99%). Extensive development can be made industrial translation this fabricated device.
We investigate thermal rectification in nanoporous silicon using a semiclassical Monte Carlo simulation method. consider geometrically asymmetric structures and the combined effects of porosity, interpore distance, pore position relative to device boundaries. Two basis geometries are considered, one which pores arranged rectangular arrays ones they form triangular arrangements. show that systems (i) with denser, compressed arrangements (i.e., smaller distances), (ii) positioned closer...
Abstract The field of thermoelectric materials has undergone a revolutionary transformation over the last couple decades as result ability to nanostructure and synthesize myriads their alloys. ZT figure merit, which quantifies performance material more than doubled after inactivity, reaching values larger two, consistently across temperatures. Central this improvement is drastic reduction in thermal conductivity due scattering phonons on numerous interfaces, boundaries, dislocations, point...
Measurements of thermal conductivity three copper-indium and two silver-zinc alloys have been made from 16 K to 90 K. The lattice has computed these measurements with the help electrical resistivity data taken simultaneously on specimens. thus obtained compared theories Klemens, Callaway Parrott in temperature range 60 Attempts assess contribution three-phonon N-processes point imperfections conductivity. Below 20 K, Lindenfeld Pennebaker. agreement seems be reasonably satisfactory
