Gelatin composition

Explosions in Ice. Twenty-four instrumented and 106 uninstiumented blasts ranging in wt from 2.5 to 40 lbs of four types of explosives (.60% Straight Gelatin, Composition C4, Atlas Coalite 7S Atlas Coalite5S) were detonated above, in contact with, and at various depth below ice surfaces... 

As they are not cap sensitive, they must be initiated by a high velocity HE, such as 75% Ammonia Gelatin, Composition B or Pentolite. Inadequate priming imparts a low initial deton velocity to a Blasting Agent and in extreme cases the reaction will die out and cause a misfire. HE boosters are sometimes spaced along a bore-...

For the BC-gelatin composite synthesized by impregnation with a gelatin solution and cross-linked with l-ethyl-3-[3-dimethylamino... 

Because of the hydrophilicity of gelatin, the WAC of the BC-gelatin composite and the BC-gelatin/cross-linkers improved with increasing concentrations of gelatin [18,57]. Because of this, gelatin was able to disrupt the crystallization of BC by inserting between cellulose molecules [28]. Nonetheless, the randomized and weak structure of the composite would likely decrease its WAC [57]. 

By comparing with BC film, the denser film with a smaller pore size was formed by the supplementation of gelatin into BC culture medium. Water molecules hardly penetrated through the small pores of the BC-gelatin composite film, resulting in the reduction of theWVTR [57].

The feasibility of additive manufactured poly(caprolactone) (PCL) silanized tricalcium phosphate scaffolds coated with carbonated hydroxyapatite-gelatin composite for bone tissue engineering has been tested (4). In order to reinforce the scaffolds to match the mechanical properties of cancellous bone, tricalcium phosphate has been modified with y-glycidoxypropyltrimethoxysilane and incorporated into PCL to synthesize a PCL/silanized tricalcium phosphate composite. y-GlycidoxypropyltrimethoxysUane is shown in Figure 3.1. 

In order to enhance the osteoconductive property of the developed PCL/silanized tricalcium phosphate scaffolds, a carbonated hydroxyapatite-gelatin composite has been coated onto the scaffolds using a biomimetic co-precipitation process, which has been characterized by scanning electron microscope (SEM) and XPS. Confocal laser microscopy and SEM images revealed a most uniform distribution of porcine bone marrow stromal cells and cell-sheet accumulation on the carbonated hydroxyapatite-gelatin composite coated PCL/silanized tricalcium phosphate scaffolds (4). 

Purthermore, the reverse transcription polymerase chain reaction and western blot analysis revealed that carbonated hydroxyapatite-gelatin composite coated PCL/silanized tricalcium phosphate scaffolds stimulate an osteogenic differentiation of bone marrow stromal cells the most in comparison to the other scaffolds. In-vitro results of SEM, confocal microscopy and proliferation rate also showed that there is no detrimental effect of the modification on biocompatibility of the scaffolds (4).
