The role of aromatic interactions in the structure and energetics of benzyl ketones.
A qualitative and quantitative energetic and structural study of dibenzyl ketone (DBK) and benzyl ethyl ketone (BEK) was carried out in order to obtain insights into the type and magnitude of aromatic interactions that these systems present in their different phases. The crystal structure of DBK was obtained by X-ray crystallography, and it shows that the conformation adopted in the crystalline...
متن کاملOn Balanced ✛-Contact Representations
In a ;-contact representation of a planar graph G, each vertex is represented as an axis-aligned plus shape consisting of two intersecting line segments (or equivalently, four axis-aligned line segments that share a common endpoint), and two plus shapes touch if and only if their corresponding vertices are adjacent in G. Let the four line segments of a plus shape be its arms. In a c-balanced re...
متن کاملPhotoinitiated Polymerization of Styrene in Microemulsions
Photoinitiated polymerization of styrene in oil/water microemulsions has been successfully performed by using dibenzyl ketone (DBK) as initiator. The system remains transparent during the whole polymerization process. The molecular weights of polymers produced are in the order of IO5, and the polydispersity indexes (PDI) are in the range 1.6-2.2. The particle sizes of the latexes produced are i...
متن کاملDisturbance and change in biodiversity.
Understanding how disturbance affects biodiversity is important for both fundamental and applied reasons. Here, I investigate how disturbances with different ecological effects change biodiversity metrics. I define three main types of disturbance effects: D disturbance (shifts in mortality rate), B disturbance (shifts in reproductive rates) and K disturbance (shifts in carrying capacity). Numer...
متن کاملCombination of Density Based and Partition Based Clustering Algorithm-DBK Means
Mining or extracting the knowledge from the large amount of data is known as data mining. Here, the collection of data increases exponentially so that for extracting the efficient data we need good methods in data mining. Data mining analyzes several methods for extracting the data. Clustering is one of the methods for extracting the data from large amount of data. Multiple clustering algorithm...
