SI 486H, Unit 1: Discrete Math

In this class, we are going to learn about some of the ways random numbers get used in computing. To paraphrase the textbook, programs that make use of random numbers are often simpler or faster than their non-random counterparts (or both!). We will start by examining what random numbers are and how computer programs can obtain them. Then the bulk of the course will be spent looking at some wel...

SI 413, Unit 9: Implementation Issues

Recall from Unit 6 that there are three ways variable storage can be allocated in a program: statically, on the stack, or from the heap. Statically allocated variables have a lifetime equal to the entire program execution; they never die. Stack allocation is tied to function calls, so anything allocated on the stack (such as local variables within a function) will simply be de-allocated when th...

Synthesis of a Dichlorodigermasilane: Double Si–Cl Activation by a Ge=Ge Unit

Halogenated oligosilanes and oligogermanes are interesting compounds in oligosilane chemistry from the viewpoint of silicon-based-materials. Herein, it was demonstrated that a 1,2-digermacyclobutadiene derivative could work as a bis-germylene building block towards double Si–Cl activation to give a halogenated oligometallane, a bis(chlorogermyl)dichlorosilane derivative.
