A portable cooking kit, apparatus and method is usable for moderating heat from an intense heat source, such as an outdoor grill or camprife. The apparatus includes a food support member, including a perforated panel surrounded by a rim. The food support member rests on top of a heat shield made from a heat-tolerant material. During use, the heat shield is stably suspended over direct, intense heat from a heat source. The food to be cooked is placed on the food support member, and the food support member may then be placed on top of the heat shield. By buffering the direct heat from the heat source, the heat shield allows food placed on the food support member to cook, but protects the underside of the food from becoming scorched. Optionally, a dome-shaped cover may be used to cover both the food support member and the heat shield.

The lower electrode is fabricated by forming a texturizing underlayer and then depositing a conductive material thereover. In one embodiment of a method of forming the lower electrode, the texturizing layer is formed by depositing a polymeric material comprising a hydrocarbon block and a silicon-containing block, over the insulative layer of a container, and then subsequently converting the polymeric film to relief or porous nanostructures by exposure to UV radiation and ozone, resulting in a textured porous or relief silicon oxycarbide film. A conductive material is then deposited over the texturizing layer resulting in a lower electrode have an upper roughened surface. In another embodiment of a method of forming the lower electrode, the texturizing underlayer is formed by depositing overlying first and second conductive metal layers and annealing the metal layers to form surface dislocations, preferably structured as a periodic network. A conductive metal is then deposited in gaseous phase, and agglomerates onto the surface dislocations of the texturizing layer, forming nanostructures in the form of island clusters. The capacitor is completed by depositing a dielectric layer over the formed lower electrode, and forming an upper capacitor electrode over the dielectric layer. The capacitors are particularly useful in fabricating DRAM cells.

A forward firing fragmentation warhead is constructed with casing materials that are pulverized upon detonation of the explosive. As a result, the lethality radius of the pulverized case fragments is no greater than that of the gas blast, thus reducing potential collateral damage. Warhead lethality may be improved by forming the fragmentation layer and explosive with dome-shapes that approximately match the shape of the advancing pressure wave. This increases fragment velocity and improves the uniformity of the fragment distribution over the forward-firing pattern. A variable-thickness pattern shaper may be placed between the fragmentation layer and explosive to provide additional shaping of the forward-firing pattern. Warhead weight and cost can be reduced by eliminating explosive at the aft end of the warhead that does not contribute to the total energy imparted to the fragments. More specifically, the aft section of the explosive and explosive containment structure may be tapered to approximately match the expansion of the pressure wave from the single-point aft detonation.
