Abstract:

Syntactic foams comprising glass or thermoplastic microballoons have gained considerable attention in recent years due to mechanical and thermal properties that are advantageous for naval and aerospace applications. This work reports a method for producing syntactic foams with unusually high-volume fraction microballoon loadings (>0.74) and its utilization for the creation of “hybrid” epoxy resin-based syntactic foams comprising various mixtures of glass and thermoplastic microballoons. Microstructural analyses using X-ray micro-computed tomography provided non-destructive quantitative char

Abstract:

In this paper, we discuss the chemorheology of epoxy based syntactic foams containing glass microballoons of varying density, with an aim of establishing the effect of microballoon loading on its processability. The primary objective is to determine the maximum microballoon loading that disperses uniformly in the resin without the aid of any diluent. The viscosity and dynamic mechanical properties of epoxy formulations containing varying amounts of glass microballoons were established by parallel plate rheometry. Our studies reveal that solventless processing of formulations with microballoon

Abstract:

Glass microballoon syntactic foams consisting of 60–70 vol% hollow glass microballoons and epoxy resin matrix have gained considerable attention in recent years due to their unique combination of mechanical properties and low density, with applications in the naval and aerospace industries. An important limitation of these materials is the volume fraction ceiling (∼0.74) and subsequent density limit (0.36 g/cm3). Utilizing thermoplastic microballoons, syntactic foams were produced with densities as low as 0.067 g/cm3, achieved by developing a method that produces epoxy/microballoon composition

The role played by hollow ceramic thin-walled aluminium oxide microballoons on the shear deformation characteristics of AZ31 Magnesium syntactic foam is studied through high-speed machining. The ceramic microballoons embedded in the AZ31 matrix provides the necessary stiffness for these novel foams. The effect of hollow ceramic microballoon properties, such as the volume fraction, thin wall thickness to diameter ratio, and microballoon diameter, profoundly affects the chip formation.

Oral route is most preferable and widely used route for the administration of drug. Microballoons becomes novel technology in pharmaceutical field in the floating drug delivery for achieving the gastric retention. Microballoons are also called as hollowspheres which are porous smooth in nature and thus show good floating properties in gastric fluid. Microballoons release the drug in controlled manner at the targeted site. Microballoons are spherical empty vesicles without core and that can remain buoyant in gastric region for prolong period of time without irritation in gastrointestinal tract.

In this work, aluminiumbased SFGMMC rings were fabricated by radial centrifugal casting.

Abstract:

Background: The drug cinnarizine is used in the treatment of vertigo and migraine. The main drawback is its very low water solubility which causes unpredictable bioavailability. Solubility is better in acidic pH. Therefore, gastro-retentive formulation would be beneficial to improve the bioavailability of the drug. Objective: The objective of the study was to prepare floating microballoons of cinnarizine which would float in the gastric fluid and release the drug in a sustained manner. Methods: Microballoons were prepared by diffusion solvent evaporation technique using polymers (Eudragit® S10

Abstract:

The first 14-MeV neutron images of imploded microballoons have been obtained on the Phébus laser facility at CEL-V. The sizes of the source have been measured, in direct-drive experiments, by means of a coded-aperture imaging system. The principle is to use a thick aperture with a diameter larger than that of the source to image the microballoon. The deconvolution of the recorded image allows one to reconstruct the image of the neutron source, and this technique allows one to obtain images at a lower neutron yield than with a conventional pinhole camera. The choice of the experimental conditio

Abstract:

Abstract: A sustained release drug delivery system for baclofen was designed to increase its residence time in the stomach without establishing contact with the mucosa. This was made possible through the preparation of microballoons by emulsion solvent diffusion-evaporation technique. The prepared microballoons were characterized for physical characteristics such as particle size, particle shape and surface morphology by scanning electron microscopy. Further, percentage yield determination, drug entrapment efficiency, in vitro buoyancy test, micromeritic investigations and in vitro drug releas

Abstract:

The objective of the present investigation was to formulate microballoons loaded with dabigatran in the polymeric core for achieving sustained release and hence improved bioavailability. Microballoons loaded with dabigatran in the polymer shell were prepared by simple solvent evaporation method using either ethyl cellulose alone or a blend of ethyl cellulose with HPMC/PVP-K30/Eudragit S100/Methyl cellulose in a fixed ratio. The percent yield of the microballoons ranged from 38.7 to 62.4% with highest yield obtained in F3. The particle size was measured using optical microscopy and the particle

Abstract:

Aluminum syntactic foams were fabricated by pressure-inﬁltrating liquid pure aluminum into packed preforms of cenosphere fly ash. The morphology, true density and porosity of fly ash microballoons were characterized. The microstructure of the syntactic foams demonstrated uniform distribution of the microballoons in the aluminum matrix and seldom infiltration of cenosphere fly ash. These foams were subjected to quasi-static uniaxial compression tests and behaved like high strength aluminum foams under compressive deformation, exhibiting an extended plateau region in the stress–strain curves.

Abstract:

Epoxy-based composites are widely used in various applications due to their excellent mechanical properties and durability, but their performance under prolonged UV exposure remains a critical concern. This study examines the impact of UV exposure on the physical, chemical, and mechanical properties of epoxy-silica microballoon composites over curing periods of 0, 200, and 400 hours. Results indicate that UV treatment increased the density from 1.0073 g/cm³ to 1.0129 g/cm³. SEM images showed a reduction in fragmentation of epoxy microballoons, indicating stronger bonding.
