Introduction
My name is Inon Sharony, and I am a doctoral student in Professor Avraham Nitzan's group at TAU.
I graduated my B.Sc. studies in 2007, majoring in Chemistry with Physics as a minor subject.
My particular area of interest within our group is heat conduction through molecular wires.

This is a schematic of a molecular junction of the type our group deals with. We study transport through the molecular bridge between two contacts. The transport may be of an electrical current or of heat, for example. In the instance shown above, the molecular junction operates as an electronic switch (M. Reed, et al., Science 1999).

Professor J. C. Cuevas at the Cond. Mat. Theo. Phys. department of the Universidad Autonoma de Madrid has uploaded a presentation he gave in which I found this slide depicting the functional character of some molecular electronics. (The original isn't mine. Please excuse the typographical error.)

A neat way of creating a nano- junction by bridging the gap between the electrodes, and then pulling them apart, thereby creating the nanoscale bridge.

Teaching
In spring semesters I was the lead lab instructor for the Computational Chemistry Laboratory, under Associate Professor Ephraim Eliav.
My responsibilities included delivering frontal lectures to the entire class, leading interactive teaching sessions, instructing lab groups (as well as grading their preparatory exercises and final reports), personally evaluating students within my lab group, developing lab exercises, maintaining the lab manual, and composing and grading quiz questions.
Since I began instructing in the lab, we have had multiple requests by research group heads and their students from other universities to have students enroll in our course, as they have found it uniquely adapted to their research needs.
Additionally, student demand had outrun lab accommodations three years in a row.
During the time in which I have been an instructor in the Computational Chemistry Lab, I've learned a great deal, both with regard to the management and leadership of an instruction team, and with regard to the course material itself.
I've tried to put an emphasis on the specific research interests of the students, and on how the Computational Chemistry Lab can give them the necessary tools for these applications.
In fall semesters I was the senior recitation master for the course Thermodynamics, under Professor Haim Diamant.
As such, my responsibilities included delivering weekly two-hour frontal lectures, personally tutoring students, synchronizing the recitations with the Professor's lectures, maintaining the existing TA guide and producing new modules, and assisting the Professor with the preparation and administration of the final exam.
The relatively long time during which I've held this position has afforded me the opportunity to acquire and hone my teaching skills, as well as improving my fundamental understanding of the course material and related topics.
In the spring semester I am the instrutor of the Molecular Dynamics computer experiment at the Advanced Laboratory in Physical Chemistry.
I recieved the experiment in a decrepid condition -- it was not revamped since its inception in 2001. Building on my past teaching experience, I gathered all the relevant material I could find and consolidated a new laboratory manual. The experiment was bolstered by adding new modules which give the students their first experience in applying such varied methodologies as mathematical modeling, random processes, probability & statistics, numerical methods (e.g. for differentiation & integration), statistical mechanics, and computational chemistry.

Physicists are very clever people. When they want to find out what something is made of, they take two of the thing and crash them together, much as a toddler would two toy trucks. When pieces fly off, they look at what originally consisted the particles they collided. The Mass-Energy equivalence shows up in particle accelerators much as this drawing depicts -- the kinetic energy that the original particles were endowed allows for particles heavier than the originals to be created, while the products carry less momentum.

אני מאמין / שאול טשרניחובסקי (1894)
שַׂחֲקִי, שַׂחֲקִי עַל הַחֲלוֹמוֹת,
זוּ אֲנִי הַחוֹלֵם שָׂח.
שַׂחֲקִי כִּי בָאָדָם אַאֲמִין,
כִּי עוֹדֶנִּי מַאֲמִין בָּךְ.
כִּי עוֹד נַפְשִׁי דְרוֹר שׁוֹאֶפֶת,
לֹא מְכַרְתִּיהָ לְעֵגֶל-פָּז,
כִּי עוֹד אַאֲמִין גַּם בָּאָדָם,
גַּם בְּרוּחוֹ, רוּחַ עָז.
רוּחוֹ יַשְׁלִיךְ כַּבְלֵי-הֶבֶל,
יְרוֹמְמֶנּוּ בָּמֳתֵי-עָל;
לֹא בָּרָעָב יָמוּת עוֹבֵד,
דְּרוֹר – לַנֶּפֶשׁ, פַּת – לַדַּל.
שַׂחֲקִי כִּי גַּם בְּרֵעוּת אַאֲמִין,
אַאֲמִין כִּי עוֹד אֶמְצָא לֵב,
לֵב – תִּקְווֹתַי גַּם תִּקְווֹתָיו,
יָחוּשׁ אֹשֶׁר, יָבִין כְּאֵב.
אַאֲמִינָה גַּם בֶּעָתִיד,
אַף אִם יִרְחַק זֶה הַיוֹם,
אַךְ בּוֹא יָבוֹא – יִשְּׂאוּ שָׁלוֹם
אָז וּבְרָכָה לְאֹם מִלְּאֹם.
יָשׁוּב יִפְרַח אָז גַּם עַמִּי,
וּבָאָרֶץ יָקוּם דּוֹר,
בַּרְזֶל-כְּבָלָיו יוּסַר מֶנּוּ,
עַיִן-בְּעַיִן יִרְאֶה אוֹר.
יִחְיֶה, יֶאֱהַב, יִפְעַל, יַעַשׂ,
דּוֹר בָּאָרֶץ אָמְנָם חָי,
לֹא בֶּעָתִיד, בַּשָּׁמַיִם –
חַיֵּי-רוּחַ לוֹ אֵין דָּי.
אָז שִׁיר חָדָשׁ יָשִׁיר מְשׁוֹרֵר,
לְיֹפִי וְנִשְׂגָּב לִבּוֹ עֵר;
לוֹ, לַצָּעִיר, מֵעַל קִבְרִי
פְּרָחִים יִלְקְטוּ לַזֵּר.
