JoVE Chemistry
JoVE Chemistry surveys a broad scope of chemical disciplines. This collection includes fundamental and applied research that investigates molecular interactions, properties, and structure spanning in the following core divisions: analytical, organic, organometallic, inorganic, bioinorganic, and biochemistry. This section also includes the design and preparation of materials and small molecules for advanced or unique applications.

Facile and Efficient Preparation of Tri-component Fluorescent Glycopolymers via RAFT-controlled Polymerization

1Department of Biochemistry, University of Missouri, 2Department of Biological Sciences, University of Missouri, 3Department of Molecular Microbiology & Immunology, University of Missouri, 4Department of Child Health, University of Missouri


JoVE 52922

An efficient, three-step synthesis of RAFT-based fluorescent glycopolymers, consisting of glycomonomer preparation, copolymerization, and post-modification, is demonstrated. This protocol can be used to prepare RAFT-based statistical glycopolymers with desired structures.

Metal-silicate Partitioning at High Pressure and Temperature: Experimental Methods and a Protocol to Suppress Highly Siderophile Element Inclusions

1Department of Earth Science, University of Toronto, 2Geophysical Laboratory, Carnegie Institution of Washington


JoVE 52725

We present a procedure to determine the metal-silicate partitioning of siderophile elements, emphasizing techniques that suppress the formation of metal inclusions in experiments for the noble metals. The results of these experiments are used to demonstrate the effect of core-formation on the highly siderophile element composition of the mantle.

Fabrication of Large-area Free-standing Ultrathin Polymer Films

1Physical and Life Sciences Directorate, Lawrence Livermore National Laboratory


JoVE 52832

We describe a method for the fabrication of large-area (up to 13 cm diameter) and ultrathin (as thin as 8 nm) polymer films. Instead of using a sacrificial interlayer to delaminate the film from its substrate, we use a self-limiting surface treatment suitable for arbitrarily large areas.

Synthesis of Indoxyl-glycosides for Detection of Glycosidase Activities

1Department of Chemistry, Faculty of Sciences, University of Hamburg


JoVE 52442

Indoxyl glycosides are well-established and widely used tools for enzyme screening and enzyme activity monitoring. Especially for glucose type structures previous syntheses proved to be challenging and low yielding. Our novel approach employs indoxylic acid esters as precious intermediates to yield a considerable number of indoxyl glycosides in good yields.

High Precision Zinc Isotopic Measurements Applied to Mouse Organs

1Institut de Physique du Globe de Paris, Institut Universitaire de France, Université Paris Diderot, 2INSERM (Institut National de la Santé et de la Recherche Médicale), U1148: Laboratory for Vascular Translational Science, Université Paris Diderot


JoVE 52479

We present the technique to measure with high precision zinc isotope ratios in mouse organs.

Supercritical Nitrogen Processing for the Purification of Reactive Porous Materials

1Hydrogen and Energy Laboratory, Empa, Swiss Federal Laboratories for Materials Science and Technology


JoVE 52817

Nitrogen is an effective supercritical fluid for extraction or drying processes due to its small molecular size, high density in the near-liquid supercritical regime, and chemical inertness. We present a supercritical nitrogen drying protocol for the purification treatment of reactive, porous materials.

Diffuse Reflectance Infrared Spectroscopic Identification of Dispersant/Particle Bonding Mechanisms in Functional Inks

1Department of Chemistry, New York City College of Technology, City University of New York (CUNY)


JoVE 52744

Formulation of stable, functional inks is critical to expanding the applications of additive manufacturing. In turn, knowledge of the mechanisms of dispersant/particle bonding is required for effective ink formulation. Diffuse Reflectance Fourier Transform Infrared Spectroscopy (DRIFTS) is presented as a simple, inexpensive way to gain insight into these mechanisms.

Self-assembly of Complex Two-dimensional Shapes from Single-stranded DNA Tiles

1Tsinghua-Peking Center for Life Sciences, School of Life Sciences, Tsinghua University, 2Wyss Institute for Biologically Inspired Engineering, Harvard University, 3Department of Systems Biology, Harvard Medical School


JoVE 52486

DNA tiling is an effective approach to make programmable nanostructures. We describe the protocols to construct complex two-dimensional shapes by the self-assembly of single-stranded DNA tiles.

Mass Spectrometric Approaches to Study Protein Structure and Interactions in Lyophilized Powders

1Department of Industrial and Physical Pharmacy, Purdue University


JoVE 52503

Here, we present detailed protocols for solid-state amide hydrogen/deuterium exchange mass spectrometry (ssHDX-MS) and solid-state photolytic labeling mass spectrometry (ssPL-MS) for proteins in solid powders. The methods provide high-resolution information on protein conformation and interactions in the amorphous solid-state, which may be useful in formulation design.

The Synthesis, Characterization and Reactivity of a Series of Ruthenium N-triphosPh Complexes

1Department of Chemistry, Imperial College London


JoVE 52689

Ruthenium phosphine complexes are widely used for homogeneous catalytic reactions such as hydrogenations. The synthesis of a series of novel tridentate ruthenium complexes bearing the N-triphos ligand N(CH2PPh2)3 is reported. Additionally, the stoichiometric reaction of a dihydride Ru–N-triphos complex with levulinic acid is described.
