wherein each a, b, c is independently 0 to 3; a+b+c=3; d is 0 to 2 and n≥1; wherein X is selected from a halogen atom selected from F, Cl, Br or I; each R is selected from H, a C.sub.1-C.sub.6 linear or branched, saturated or unsaturated hydrocarbyl group, or a silyl group [SiR′.sub.3]; further wherein each R′ of the [SiR′.sub.3] is independently selected from H, a halogen atom selected from F, Cl, Br or I, a C.sub.1-C.sub.4 saturated or unsaturated hydrocarbyl group, a C.sub.1-C.sub.4 saturated or unsaturated alkoxy group, or an amino group [—NR.sup.1R.sup.2] with each R.sup.1 and R.sup.2 being further selected from H or a C.sub.1-C.sub.6 linear or branched, saturated or unsaturated hydrocarbyl group, provided that when c=0, d≠0; or d=0, c≠0.

Materials which react with (“scavenge”) sulfur compounds, such as hydrogen sulfide and mercaptans, are useful for limiting sulfur-induced corrosion. Surface-modified particles incorporating a hexahydrotriazine moiety are disclosed and used as sulfur scavengers. These surface-modified particles are used a filter media in fixed filter systems and as additives to fluids including sulfur compounds. The hexahydrotriazine moiety can react with sulfur compounds in such a manner as to bind sulfur atoms to the surface-modified particles, thus allowing removal of the sulfur atoms from fluids such as crude oil, natural gas, hydrocarbon combustion exhaust gases, sulfur polluted air and water. The surface-modified particles may, in general, be sized to allow separation of the particles from the process fluid by sedimentation, size-exclusion filtration or the like.

The present invention relates to novel microporous zirconium silicate compositions that are formulated to remove toxins, e.g. potassium ions, from the gastrointestinal tract at an elevated rate without causing undesirable side effects. The preferred formulations are designed avoid increase in pH of urine in patients and/or avoid potential entry of particles into the bloodstream of the patient. Also disclosed is a method for preparing high purity crystals of UZSi-9 exhibiting an enhanced level of potassium exchange capacity. These compositions are particularly useful in the therapeutic treatment of hyperkalemia.

Methods of forming a metal film having a metal halide with a reducing agent are disclosed. The reducing agent, the reducing agent includes a group IV element containing heterocyclic compound, a radical initiator, an alkly alane, a diborene species and/or a Sn(II) compound.

Compounds and method of preparation of Si—X and Ge—X compounds (X=N, P, As and Sb) via dehydrogenative coupling between the corresponding unsubstituted silanes and amines (including ammonia) or phosphines catalyzed by metallic catalysts is described. This new approach is based on the catalytic dehydrogenative coupling of a Si—H and a X—H moiety to form a Si—X containing compound and hydrogen gas (X=N, P, As and Sb). The process can be catalyzed by transition metal heterogenous catalysts such as Ru(O) on carbon, Pd(O) on MgO) as well as transition metal organometallic complexes that act as homogeneous catalysts. The —Si—X products produced by dehydrogenative coupling are inherently halogen free. Said compounds can be useful for the deposition of thin films by chemical vapor deposition or atomic layer deposition of Si—containing films.
