A biodegradable polymeric sheet may be configured to undergo biodegradation on the ground responsive to an exposure to free air and natural day light. The biodegradable polymeric sheet may include a first layer comprising polysaccharide at a weight % of between 15% to 50% and a polyester matrix, the first layer is configured to form a water barrier when in contact with water; a second layer comprising a polysaccharide at a weight % of at least 40% and a polyester matrix; and a third layer comprising polysaccharide at a weight % of between 15% to 50%, a polyester matrix and an additive configured to accelerate disintegration of the polymeric sheet when exposed to natural day light, the third layer is configured to form a water barrier when in contact with water.

Bio-degradable polymeric sheet

Provided is an organic solvent-free method for producing a plurality of microsphere having an average diameter of less than 500 &#x3bc;m in diameter and having average contact angle &#x3b8;c greater than 140&#xb0;, consisting essentially of a biocompatible hot-melt carrier vehicle and a payload substance to be delivered, including melting and mixing a polymer carrier vehicle which is solid at room temperature and at least one payload substance, and dispensing microportions of the molten mixture through a droplet-forming space onto a cooled solid superoleophobic surface.

Microspheres and method for producing them

Provided are polymers having a repeating unit including at least one astaxanthin moiety. Also provided are processes for preparing the polymers and various uses thereof.

Astaxanthin based polymer and uses thereof

A method of delivering over the air, shelled portions of fluids or granular substances containing effective ingredients, to a target, includes the following stages: selecting a type and a size of the shelled portions containing the required effective ingredients, based on mission parameters and physical data of a scene containing the target; conveying the shelled portions to a delivery point, based on the mission parameters and the physical data; and ballistically delivering the shelled portions towards the target, wherein the shelled portions comprise fluids or granular substances covered by shells that provide the shelled portions a ballistic coefficient that is significantly higher than a ballistic coefficient of similar portions without the shells.
