To Bond or Not to Bond: That is the Question
IEEE Transactions on Industry Applications, 2010The bonding of electrical equipment plays a crucial role in maintaining the same potential between conductive parts likely to be energized and conductive parts liable to introduce a “zero” potential into the premises. Voltage rises between such parts are unsafe, as they may induce harmful currents through the human body, the magnitude of which may vary

Visible Light-Driven Radical-Mediated C-C Bond Cleavage/Functionalization in Organic Synthesis.
Chemical Reviews, 2020Thermal C-C bond cleavage reactions allow the construction of structurally diverse molecular skeletons via predictable and efficient bond reorganizations.

I use a new technique to derive a closed-form solution for the price of a European call option on an asset with stochastic volatility. The model allows arbitrary correlation between volatility and spot-asset returns. I introduce stochastic interest rates

The hydrogen bond in the solid state.
Angewandte Chemie, 2002The hydrogen bond is the most important of all directional intermolecular interactions. It is operative in determining molecular conformation, molecular aggregation, and the function of a vast number of chemical systems ranging from inorganic to ...

Structural Chemistry, 2019
Even after roughly a century of quantum theory, there is still debate, sometimes rather contentious, as to the nature of the chemical bond—or is it bonds, or is it bonding? In this brief overview, we summarize some of the prominent approaches to this and related issues.

Bond-valence parameters for solids
, 1991Bond-valence parameters which relate bond valences and bond lengths have been derived for a large number of bonds. It is shown that there is a strong linear correlation between the parameters for bonds from cations to pairs of anions. This correlation is

The bond/old-bond spread [PDF]
This paper studies the spread between the newly issued 30 year Treasury bond and the old 30 year bond. The spread follows a systematic pattern over the auction cycle: it begins high at an auction date, and converges toward zero by the next auction date. I document the profits on establishing a long old bond/ short new bond convergence trade and rolling

Carboxylate-assisted transition-metal-catalyzed C-H bond functionalizations: mechanism and scope.
Chemical Reviews, 2011The site-selective formation of carbon-carbon bonds through direct functionalizations of otherwise unreactive carbon-hydrogen bonds constitutes an economically attractive strategy for an overall streamlining of sustainable syntheses.

Savings bonds, retractable bonds and callable bonds
Journal of Financial Economics, 1977Abstract Savings bonds, retractable bonds and callable bonds are each equivalent to a straight bond with an option. Neglecting default risk the value of these contingent claims depends upon the riskless interest rate. This paper employs the option pricing framework to value these bonds, under the assumptions that the interest rate follows a Gauss ...
