Insensitive energetic salts : A series of furazan‐functionalized tetrazolate‐based energetic salts (see figure) were synthesized and characterized. All of the salts exhibit excellent thermal stabilities and high positive heats of formation.

Attractive chlorine : Noncovalent interactions between chlorine or bromine atoms and aromatic rings in proteins open up a new method for the manipulation of molecular recognition. Substitution at distinct positions of two factor Xa inhibitors improves the free energy of binding by interaction with a tyrosine unit. The generality of this motif was underscored by multiple crystal structures as well as high‐level quantum chemical calculations (see picture).

Pepped up polymers : The synthesis and properties of novel chiral cyclic peptides designed to complex with suitable polymers through hydrogen bonding are described. A substituted cyclic peptide self‐assembles into supramolecular nanotubes and develops noncovalent interactions with poly(vinyl alcohol) (PVA) by means of its carboxyl side chains.

Taking a strand : Aptamers are small single‐stranded oligonucleotides that fold into a well‐defined 3D structure and interact with high affinity and specificity with their target molecules, thereby inhibiting their biological functions. Aptamers can be synthesized by either chemical and/or enzymatic procedures and can thus be considered as both chemical and biological substances. The current status and new developments in this area are described.

Without the need for organohalide precursors , the convenient and general synthesis of aryl (or diaryl) sulfides can be achieved by using aryl carboxylic acids and thiols or disulfides for decarboxylative C? S cross‐coupling catalyzed by a bimetallic system (see scheme).
