The Plan includes the completion of a year-long
period of monitoring key manufacturing process
input variables, and subsequent quantitative
analysis of resultant outputs. Process outputs
were previously defined at the beginning
of the year-long period both internally
and through target market research, and
include parameters such as:
For dispersion products, the shelf life
of the dispersion (i.e. period of time during
which half of total dispersed material has
settled)
Analysis of process outputs, followed
by cyclic and iterative key process input
modifications, drove the enhancement of
The Company's level of confidence in defining
its quantitative process capability, with
respect to the above parameters. This
work was performed for each of the nanomaterials
offered as products. Going forward, The
Company will be able to speak with even
greater confidence than previously with
regard to its capability to achieve market-driven
specification targets.
This key differentiator, defined as a
significant product value enhancement,
allows The Company to continue along a
path defined by its Mission
Statement, created in parallel with
its founding in 2003.

Meliorum Emphasizes an Example
of The Company's High Quality Gold Colloids
in Research Applications:
Multiple discrete sizes and tight size
distributions available
Meliorum's nanomaterial colloids have
been characterized on numerous occasions
by university and industrial researchers
for use in a wide array of cutting-edge
applications. We invite you to review
an example of research performed with
our gold colloid products. Several samples
of gold dispersions whose particle populations
have discrete mean diameters were used.
Mean sizes were, as characterized, 1.8
nm, 2.9 nm, 7.4 nm, and 23 nm for each
of the four samples, with standard deviations
of 1.8, 0.6, 1.1 and 8.1 nm, respectively.
Similar discrete and nonoverlapping population
particle size distributions were observed
for silver dispersions.

Meliorum Technologies Announces
its Nanofluid Product Suite
Meliorum is pleased to announce the
introduction of nanofluids of various
metals, including gold, platinum, copper
and silver. Nanofluids typically manifest
as suspensions of semiconductors, oxides
or metals with concentrations at times
as high as 50% by volume. Due to the unique
properties of nanomaterials, however,
the effective viscosity of the nanofluid
very closely resembles that of its solvent
(typically within a few to ten percent).
Meliorum nanofluid functionality has already
been demonstrated in applications requiring
fluids with unusually high thermal conductivity.
Although precious metals are most commonly
employed in nanofluid suspensions, applications
for semiconductors and oxides are currently
being investigated. For example, a 50%
by volume cerium oxide nanofluid for abrasive
applications has been shown to have a
viscosity within 10% of that of its constituent
solvent. Solvent options are user-specifiable,
based on the particular application. Contact
Meliorum today to receive technical support
or more information.

Meliorum Technologies Introduces
Ceria and Zinc Oxide Materials
Meliorum Announces the introduction
of cerium oxide abrasive and zinc oxide
UV absorption materials in the sub-10nm
size range. Cerium oxide has recently
experienced increased favor for inclusion
in semiconductor abrasive aplications,
due to its unique planarization properties,
particularly in the nano size range. Available
as powder, aqueous or organic suspensions,
Meliorum's cerium oxide nanomaterial is
versatile enough to be incorporated in
your particular application.
A common compound in many
industrial, household and personal care
products, zinc oxide exhibits ultraviolet
light absorption properties which make
it an ideal functional material insunblock,for
example. However, light scattering from
large micron-diameter particles results
in a cosmetically unappealing white color
exhibited by the material. Zinc oxide
nanomaterials fabricated and distributed
in a size range which, under proper conditions,
exhibits substantially reduced light scattering,
thereby promoting material trnasparency
when properly suspended in various solvents.
Call or email Meliorum today to discuss
your unique zinc oxide application requirements.
