[0003] Multicore fiber technology for spatial multiplexing is being consideredboth for long haul communications and for short distance optical fiberinterconnects used within data centers and high-performance computers.
Connecting multicore fibers requires very precise positioning of theindividual cores, with typical tolerances being a fraction of a micrometer.
This key requirement dictates the choice of materials and processes whenforming the optical fiber preform.
[0004] Single-core and multi-core fibers can be fabricated from a glass
preform made using what is referred to in the art as an all-glass process. The
all-glass process utilizes a bulk cladding glass with one or more
precision-formed axial holes sized to accommodate respective one or morecanes that define the core(s) of the preform and thus the optical fiber formed
from the glass preform.
[0005] An all-glass process may be preferred over deposition-based processes(e.g., an outside vapor deposition (OVD) process) involving soot layering, sootpressing and soot drilling, sintering, and consolidation to convert the soot toglass. The ability to precision grind the outer surface of the cladding glass toa select diameter and to perform precision drilling of the cladding glass
provides both the precision and flexibility of choosing a variety of spacings,
shapes, and arrangements of the one or more axial holes when forming theglass preform.

＊＊＊START＊＊＊[0006] Unfortunately, the all-glass process is relatively expensive and timeconsuming. The precision hole drilling takes time, the one or more canes
need to be formed to define a select refractive index profile and then added tothe cladding glass, and the entire structure needs to be consolidated in a
furnace to form the solid glass preform. To make the glass preform ofsufficient length, it may be necessary to axially combine separate glass
cladding sections, which involves precise alignment of the axial holes. The
consolidation process typically requires a special support fixture to hold theglass claddings sections and canes in a consolidation furnace and thenremoving the resulting solid glass preform from the furnace, unloading itfrom the support fixture and then operably supporting it at the draw furnaceof the draw system to make the optical fiber.

Any ingredient, which does not interfere with the crosslinking action or does
not adversely affect propellant stability, may be used in crosslinked modified
double base propellants. A metal powder, such as aluminum, is used as a fuelto obtain a high theoretical specific impulse. A liquid fuel, such ascarboranylmethyl acrylate, has also been incorporated. A solid oxidizer suchas ammonium perchlorate should also be present in the propellant to obtainacceptable delivered impulses. Nitroguanidine, cyclotetramethylene
tetranitramine (HMX) and cyclotrimethylene trinitramine were also
successfully incorporated as oxidizers into the crosslinked solution or slurry
cast propellants. 2-Nitrodiphenylamine and resorcinol are usually used asstabilizers in modified double base propeilants. That amine or ethyl

Centralite (symmetrical diethyldiphenylurea) can be used in crosslinked
versions but resorcinol does react with the diisocyanate. Resorcinol diacetate
does not react with a diisocyanate and has been used as the second stabilizer.
The choice of a plasticizer, which is composed of explosive (an organicnitrate) and non-explosive (an ester, ketone, nitrile or nitro compound)components, is likewise only limited bv consideration of reactivity andcompatibility and the additional consideration of volatibility. In addition tonitroglycerin, other organic nitrates such as diethvlene glycol nitrate,
triethylene glycol dinitrate and metriol (tri-methylol methane) trinitrate
have been successfully used in crosslinked pro pellants.

Esters such as triacetin (glycerol triacetate), diallyl phthalate, di-n-propyl
adipate and dimethyl sebacate and nitriles such as adiponitrile have beenused and a ketone such as isophorone (3,5,5-trimethyl-2-cyclo- hexen-1-one)or a nitro compound such as o-chloronitrobenzene or dinitrotoluene can beused.

A 20 mL vial was charged with cyclopropanesulfonamide (2.09 mmol),Cs2CO3 (3.49 mmol), 1-tert-butyl 3-methyl
2-(2-chloropyrimidin-4-yl)malonate (1.74 mmol) and dioxane (2 mL). The
mixture was degassed and backfilled with N2 for 5 mins. In a separate 20mL vial, the above prepared catalyst (0.174 mmol) and dioxane (1 mL) werestirred under N2 for 5 mins then added to the first vial. The resulting
reaction mixture was heated under N2 at 60 °C for 2.5 hrs. The mixture wasallowed to cool to RT, diluted with H2O (2 mL) and then carefully acidified
with 1M HCl (aq, 5 mL) until pH 4. The residue was extracted with EtOAc (2x 20 mL), the organic phase was filtered through a phase separator and thesolvent was removed in vacuo. The yellow residue was triturated with TBME
(10 mL), filtered and washed with TBME (10 mL) to give 1-tert-butyl
3-methyl 2-(2-(cyclopropanesulfonamido)pyrimidin-4-yl)malonate (0.394 g,

1.05 mmol, 60% yield) as a white solid.

14. The method of claim 13, wherein the homogenizing is performed byfurther adding one or a mixture of two or more selected from the groupconsisting of fatty acid and phospholipid.
15. The method of claim 13, wherein the homogenizing is performed byfurther adding a pro-oxidant.

compound and a ferric ion are chelated,
wherein a shell thickness of the hollow particle is 1/1,000 to 1/50 based on anaverage diameter of the hollow particles.
