Lithium-Silicon Batteries
Lithium-ion batteries are the now
dominating chemistry within battery applications, having 60% of worldwide sales
values in portable batteries. Lithium-ion chemistries have the highest energy
density among the commercialized rechargeable batteries today which originates
from their high working potential combined with their high capacities and low
weight. Yet their performances are not enough for some future demands, which
include electric vehicles, power grid load levelling, and peak

Improvement of Hydrogen Storage with Nanomaterials
Over recent
years, nanomaterials got interested due to its unusual electrical, mechanical,
electronic, magnetic, surface, and optical properties. These high
surface/volume ratio nanomaterials have important implications for storing Hydrogen
and energy. Hydrogen is one of the evolving renewable energy sources, and it's
abundant, light, storable, and energy-dense. Metal Hydrides solve the
challenges of hydrogen storage and release. Nanostructured systems such as
boron nitride nanotubes

Vapor-Sensitive Materials
Polysaccharides are the long-chain carbohydrates with a significant
role in nature and biological systems such as water retention and molecular
recognition. The structures of polysaccharides in their microscale are hardly
ever applied in vitro due to the challenges with regulating the self-assembly. Vahid Javan KouzegaranAnalytical Chemist (Ph.D.) / Nanografi Nano TechnologyIntroductionIt's been demonstrated that cyanobacterial polysaccharides known to be sacran,
are capable of sel

Non-Newtonian Fluids and Their Place in the Everyday Life
Non-Newtonian fluids have
peculiar rheological behaviors and show non-linear viscosity dependency to
shear stress or shear rate changes. We encounter non-Newtonian fluids in our
daily life more than we might think. Non-Newtonian fluids can be found in a wide
range of products from food products to body armors.IntroductionFluids hold
an important place in every aspect of life. Naturally, they have been the center
of researches since the beginning of our scientific quest. Amongst n
