Electrochemistry intersected nanoscience 25 years ago when it became possible to control the flow of electrons through single molecules and nanostructures. Many surprises and a wealth of understanding were generated by these experiments. Professor Nongjian Tao was among the pioneering scientists who created the methods and technologies for advancing this new frontier. Achieving a deeper understanding of charge transport in molecules and low-dimensional materials was the first priority of his experiments, but he also succeeded in discovering applications in chemical sensing and biosensing for these novel nanoscopic systems. In parallel with this work, the investigation of a range of phenomena using novel optical microscopic methods was a passion of his and his students. This article is a review and an appreciation of some of his many contributions with a view to the future.

In an era of interdisciplinary scientific research, new methodologies are necessary to simultaneously advance several fields of study. One such case involves the measurement of electron spin effects on biological systems. While magnetic effects are well known in biology, recent years have shown a surge in published evidence isolating the dependence on spin, rather than magnetic field, in biological contexts.

Electrolyte engineering has emerged as an effective strategy for stabilizing Zn-metal anodes. However, a single solute or solvent additive is far from sufficient to meet the requirements for electrolyte cycling stability. Here, we report a new-type high-entropy electrolyte composed of equal molar amounts of Zn(OTf)2 and LiOTf, along with equal volumes of H2O, triethyl phosphate, and dimethyl sulfoxide, which enhances electrolyte stability by increasing solvation entropy.

As an approximation to SDSCI [static-dynamic-static (SDS) configuration interaction (CI), a minimal MRCI; , , 1481], SDSPT2 [ , , 2696] is a CI-like multireference (MR) second-order perturbation theory (PT2) that treats single and multiple roots in the same manner. This feature permits the use of configuration selection over a large complete active space (CAS) to end up with a much reduced reference space ̃, which is connected only with a small portion (̃) of the full first-order interacting space connected to . The most expensive portion of the reduced interacting ̃ space (which involves three active orbitals) can further be truncated by partially bypassing its generation followed by an integral-based cutoff.

Rigid, conjugated molecules are excellent candidates as molecular wires since they can achieve full extension between electrodes while maintaining conjugation. Molecular design can be used to minimize the accessible pi surface and interactions between the bridging wire and the electrode. Polyynes are archetypal molecular wires that feature a rigid molecular framework with a cross-section of a single carbon atom.

Three bisferrocene-based bis(acylthiourea) positional isomers, namely, 1,2-bis(ferrocenylcarbonylthioureido)benzene (1), 1,3-bis(ferrocenylcarbonylthioureido)benzene (2) and 1,4-bis(ferrocenylcarbonylthioureido)benzene (3), all [Fe(CH)(CHNOS)], have been synthesized via facile nucleophilic addition reactions of 2.3 equivalents of ferrocenoyl isothiocyanate with o-, m- and p-phenylenediamine, respectively. The structures of the three new synthesized isomers were fully characterized by H NMR, C NMR, IR and UV-Vis spectroscopy, elemental analyses and cyclic voltammetry.
