The structural, magnetic and theoretical aspects are described for three triangular lanthanide complexes, [Tb(OH)(teaH)(paa)]Cl (1), [Dy(OH)(teaH)(paa)]Cl (2) and [Ho(OH)(teaH)(paa)]Cl (3), and a hexanuclear wheel of formula [Dy(pdeaH)(NO)] (4) [teaH = triethanolamine, paaH = N-(2-pyridyl)-acetoacetamide and pdeaH = 3-[bis(2-hydroxyethyl)amino]propan-1-ol]. Each complex displays single molecule toroidal behaviour as rationalised using high-level ab initio calculations. Complexes 2 and 3 are the first examples of mixed moment single molecule toroidal complexes featuring non-Kramers ions.

Background: Populus tomentosa, known as Chinese white poplar, is indigenous and distributed across large areas of China, where it plays multiple important roles in forestry, agriculture, conservation, and urban horticulture. However, limited accessibility to the mitochondrial (mt) genome of P. tomentosa impedes phylogenetic and population genetic analyses and restricts functional gene research in Salicaceae family.

Liquid cell transmission electron microscopy (LCTEM) is a powerful technique for investigating crystallisation dynamics with nanometre spatial resolution. However, probing phenomena occurring in liquids while mixing two precursor solutions has proven extremely challenging, requiring sophisticated liquid cell designs. Here, we demonstrate that introducing and withdrawing solvents in sequence makes it possible to maintain optimal imaging conditions while mixing liquids in a commercial liquid cell.

Sensitive, rapid and label-free biochemical sensors are needed for many applications. In this protocol, we describe biochemical detection using FLOWER (frequency locked optical whispering evanescent resonator)-a technique that we have used to detect single protein molecules in aqueous solution as well as exosomes, ribosomes and low part-per-trillion concentrations of volatile organic compounds. Whispering gallery mode microtoroid resonators confine light for extended time periods (hundreds of nanoseconds).

In recent years, a great interest has been focused on the prebiotic origin of nucleic acids and life on Earth. An attractive idea is that life was initially based on an autocatalytic and autoreplicative RNA (the RNA-world). RNA duplexes are right-handed helical chains with antiparallel orientation, but the rationale for these features is not yet known.

Background: Localized surface plasmon resonance (LSPR) sensor has drawn continuous attention to application of the detection of antibody, protein, virus, and bacteria. However, natural recognition molecules, such as antibody, which possess some properties, including low thermal stability, complicated operation and high price, uncontrollability of length and size and a tendency to accumulate easily on the surface of chip to reduce the sensitive of method. Furthermore, common blocking agents are not suitable for development of novel biosensors.
