From molecules to crystal engineering: supramolecular isomerism and polymorphism in network solids.

Recent Advances in Bulk Heterojunction Polymer Solar Cells

This review describes a multidimensional treatment of molecular recognition phenomena involving aromatic rings in chemical and biological systems. It summarizes new results reported since the appearance of an earlier review in 2003 in host-guest chemistry, biological affinity assays and biostructural analysis, data base mining in the Cambridge Structural Database (CSD) and the Protein Data Bank (PDB), and advanced computational studies. Topics addressed are arene-arene, perfluoroarene-arene, S⋅⋅⋅aromatic, cation-π, and anion-π interactions, as well as hydrogen bonding to π systems. The generated knowledge benefits, in particular, structure-based hit-to-lead development and lead optimization both in the pharmaceutical and in the crop protection industry. It equally facilitates the development of new advanced materials and supramolecular systems, and should inspire further utilization of interactions with aromatic rings to control the stereochemical outcome of synthetic transformations.

Aromatic rings in chemical and biological recognition: energetics and structures.

Nanocomposites, a high performance material exhibit unusual property combinations and unique design possibilities. With an estimated annual growth rate of about 25% and fastest demand to be in engineering plastics and elastomers, their potential is so striking that they are useful in several areas ranging from packaging to biomedical applications. In this unified overview the three types of matrix nanocomposites are presented underlining the need for these materials, their processing methods and some recent results on structure, properties and potential applications, perspectives including need for such materials in future space mission and other interesting applications together with market and safety aspects. Possible uses of natural materials such as clay based minerals, chrysotile and lignocellulosic fibers are highlighted. Being environmentally friendly, applications of nanocomposites offer new technology and business opportunities for several sectors of the aerospace, automotive, electronics and biotechnology industries.

Growth-Induced Evolution of Polarity in Organic Crystals

A Q-switched Nd:YAG laser transversely pumped with a 300-W quasi-cw diode generated pulses at 1.06 μm with intracavity energies of up to 10 mJ. Intracavity Raman shifting in a 60-mm-long Ba(NO3)2 crystal led to pulses with energies of 2.5 mJ at 1197 nm. The output pulse duration was reduced to 8.5 ns compared to 50 ns at the fundamental wavelength. Beam quality improvement was observed. A NaBrO3 Raman laser generated pulse energies of 0.4 mJ at 1163 nm with a crystal of only 18 mm length. The Raman radiation was frequency doubled into the yellow spectral region from 580 nm to 599 nm, which is difficult to reach with other solid-state lasers.
