Exploiting Imine Photochemistry for Masked N‐Centered Radical Reactivity
(CRC PressWiley Periodicals, Inc., 2019-12-19)
This report details the development of a masked N‐centered radical strategy that harvests the energy of light to drive the conversion of cyclopropylimines to 1‐aminonorbornanes. This process employs the N‐centered radical ...
Magnetic Alignment of Polymer Macro‐Nanodiscs Enables Residual‐Dipolar‐Coupling‐Based High‐Resolution Structural Studies by NMR Spectroscopy
(Wiley Periodicals, Inc., 2019-10-14)
Experimentally measured residual dipolar couplings (RDCs) are highly valuable for atomic‐resolution structural and dynamic studies of molecular systems ranging from small molecules to large proteins by solution NMR ...
β‐Mannosylation through O‐Alkylation of Anomeric Cesium Alkoxides: Mechanistic Studies and Synthesis of the Hexasaccharide Core of Complex Fucosylated N‐Linked Glycans
(Wiley Periodicals, Inc.CRC Press, 2020-04-23)
Mass Activated Droplet Sorting (MADS) Enables Highâ Throughput Screening of Enzymatic Reactions at Nanoliter Scale
(Wiley Periodicals, Inc., 2020-03-09)
Microfluidic droplet sorting enables the highâ throughput screening and selection of waterâ inâ oil microreactors at speeds and volumes unparalleled by traditional wellâ plate approaches. Most such systems sort using ...
Strong Valence Band Convergence to Enhance Thermoelectric Performance in PbSe with Two Chemically Independent Controls
(Wiley Periodicals, Inc., 2021-01-04)
We present an effective approach to favorably modify the electronic structure of PbSe using Ag doping coupled with SrSe or BaSe alloying. The Ag- 4d states make a contribution to in the top of the heavy hole valence band ...
Enhanced Drug Delivery by Dissolution of Amorphous Drug Encapsulated in a Water Unstable Metal–Organic Framework (MOF)
(Wiley-VCH, 2019-11-18)
Encapsulating a drug molecule into a water‐reactive metal–organic framework (MOF) leads to amorphous drug confined within the nanoscale pores. Rapid release of drug occurs upon hydrolytic decomposition of MOF in dissolution ...
Glassy Carbon low-temperature thermodynamic properties
(Elsevier, 1970-11)
The heat capacity of Glassy Carbon was measured by adiabatic calorimetry from 5 to 350 K and has no transitions or thermal anomalies. It parallels that of pyrolytic graphite annealed at 2600 [deg]C in showing an approximate ...
Compound formation and melting behavior in theAB compound and rare earth oxide systems
(Elsevier, 1990-03)
Compound formation in the systems of the covalent compounds BeO, AlN, and SiC withR2O3(rare earth oxides) is described. Tentative phase diagrams of the AlNNd2O3 and AlNEu2O3 systems are presented.
Fluoride catalyzed rearrangements of polysilsesquioxanes, mixed Me, vinyl T 8 , Me, vinyl T 10 and T 12 cages
(John Wiley & Sons, Ltd., 2010-08)
Insoluble mixtures of polyvinylsilsesquioxane, -(vinylSiO 1.5 ) n - PVS, and polymethylsilsesquioxanes, -(MeSiO 1.5 ) n - PMS, in THF at ambient when treated with catalytic amounts (1–5 mol%) of fluoride ion introduced ...
Rate constant of the reaction of chlorine atoms with methanol over the temperature range 291–475 K
(Wiley Subscription Services, Inc., A Wiley Company, 2010-02)
The rate constant of the reaction Cl + CH 3 OH ( k 1 ) has been measured in 500–950 Torr of N 2 over the temperature range 291–475 K. The rate constant determination was carried out using the relative rate technique with ...
