Mesophotic reefs (30–150 m) occur in the tropics and subtropics at depths beyond most scientific diving, thereby making conventional surveys challenging. Towed cameras, submersibles, and mixed-gas divers were used to survey the mesophotic reef fish

Visual survey by divers using open-circuit (OC) SCUBA is the most widely used approach to survey coral reef fishes. Therefore, it is important to quantify sources of bias in OC surveys, such as the possibility that avoidance of OC divers by fishes ca

The Horiuti-Polanyi mechanism has been considered to be universal for explaining the mechanisms of hydrogenation reactions in heterogeneous catalysis for several decades. In this work, we examine this mechanism for the hydrogenation of acrolein, the

A few important examples are described to show that well-chosen molecular probes in organic reactions on heterogeneous catalysts can reveal much about the nature of the active sites and reaction mechanisms. This approach using norbornadiene in hydrog

The comparative reactivity of 7-oxa-benzonorbornadiene in metathesis copolymerization reactions using Ru-based initiators has been investigated. It is as reactive as norbornene, about 8 times more reactive than cyclopentene, and at least 19 times mor

High trans and mainly cis directing Grubbs Ru initiators, I–III, and IV, respectively have been investigated as catalysts for metathesis copolymerization of norbornene and cyclopentene. When the Lewis acid, MoCl5 or WCl6, is added to these Lewis ba

Methylaluminoxane (MAO) alone acts as a weak catalyst for the ring-opening metathesis polymerisation of norbornene, thereby providing good evidence that some transient [Al]C metallacarbenes are formed and propagate the reaction. A novel general
