Abstract: A method of forming graphene comprises patterning an organic material monolayer disposed on a first substrate to yield a patterned organic material monolayer, and supplying thermal energy to the patterned organic material monolayer. The thermal energy is sufficient to carbonize the monolayer to form a patterned layer of graphene on said substrate.

Abstract: A method of forming graphene comprises supplying energy to at least a portion of an organic material monolayer disposed on a substrate. The energy is sufficient to carbonize the at least a portion of the monolayer exposed thereto to form a layer of graphene on the substrate.

Abstract: This invention is comprised of the following innovations: various devices/instruments which may be used in the preparation of a compact monolayer [made up of a suitable organic material (or organic compound)] as well as the carbonization of the latter; efficient methods for preparing a compact monolayer which is free from all “other” materials that were used in the various processes involved in the said preparation of the said compact monolayer; various methods for carbonizing a compact monolayer by means of a suitable “heat source” (which allows the application of a sudden searing “heat” extremely quickly) in order to produce a graphene layer, where the said heat source may be a “hot surface” or a suitable “radiation type beam” such as a suitable laser beam, or a suitable maser beam, or a suitable electron beam; and finally, various methods to provide a protective layer for a graphene layer.

Abstract: A method of making a thick and more graspable flap at the open end of the condom (to allow easier manipulation of the latter); new methods of rolling up condoms; and the devices/instruments required to roll up the said condom according to such methods are disclosed. New methods of rolling up condoms permit the manufacturing of a new generation of condoms that are made of considerably thinner and stronger synthetic materials which provide numerous advantages: easier unrolling, vastly improved feel/sensation, stronger (less prone to tearing), no microscopic pores in the sheath, non-allergenic, allowing concomitant use of an spermicide, and even permitting the condom to be worn “inside out” or in the correct manner.

Abstract: A condom and method of preparing condoms for packaging are disclosed. The rim of a conventional condom is moved close to the apex to create a double layered shaft. The shaft is then rolled from the posterior end to form a ring which lies behind the rim. A section of the shaft can be left unrolled to permit easier unrolling by the user. The method of condom preparation permits the condom to be applied in either direction.
