'Im worried' Interlocked fingers are a way of holding ones own hands for comfort while also protecting the body. The researchers coined the name "clippane" to describe the new family of MIMs formed by two entangled or fastened molecular tweezers. Arms draped over the belly may mean he is holding back. two senior women smile at a phone, while they arms are interlocked - interlocked arms stock pictures, royalty-free photos & images.

Group of young women have arms interlocked as they hold a metal pipe and protest the Vietnam War at Fort Dix, a major transshipment point for. Download and buy this stock image: Four arms interlocked in unity - IKO-20830017 from agefotostocks photo library of over 110+ million high resolution. For an analogous tweezer lacking these groups, the dimeric structure is in equilibrium with the monomeric structure. hands - interlocked arms stock illustrations. The two components of the mechanically interlocked molecule cannot separate because the bulky tert-butyl groups prevent disassembly through slippage. The interlocked structure is unique as it is produced by the self-aggregation of two U-shaped structures. The metallotweezers were synthesized from the corresponding pyrene-imidazolylidene gold complex via a reaction with 1,12-diethylnyl-acridine] as the tether precursor. These arms contain a gold atom bound to a tert-butyl-functionalized pyrene-imidazolylidene group (pictured).
A young girl in a black jacket with hands clasped in prayer and closing her eyes is standing by the fire. Typical molecular topologies and architectures that contain mechanical bonds are rotaxanes, catenanes, molecular knots, and molecular Borromean rings.Įduardo Victor Peris, University Jaume I, Castellón, Spain, and colleagues have developed a new type of MIM based on the coupling of two so-called metallotweezers, which consist of a rigid tether linking two flat "arms". A girl with folded hands in prayer and eyes closed is standing by the fire. Protected behind glass in its original brass mat and preserver and sealed with its original paper seals. The man is posing seated with his wife one can note the couples arms are interlocked in an affectionate pose.
Mechanically interlocked molecules (MIMs) are held together by mechanical bonds, i.e., they consist of two or more components that are entangled in such a way that they cannot be separated without breaking a covalent bond.
