Perturbed angular correlation (PAC) spectroscopy of dilute zirconia alloys
and YBa₂Cu₃0₇₋x, ceramic superconductors at elevated temperature have been
measured using ¹¹¹Cd as the probe.
The oxygen vacancy concentration in the zirconia samples was controlled by
doping with yttrium or indium, which introduce vacancies, or with niobium, which
removes vacancies. A...
Iterative algorithms are simple yet efficient in solving large-scale optimization problems in practice. With a surge in the amount of data in past decades, these methods have become increasingly important in many application areas including matrix/tensor recovery, deep learning, data mining, and reinforcement learning. To optimize or improve iterative algorithms,...
In spite of their importance in many systems, liquid surfaces have been
explored at the microscopic level to a much lesser extent than solids. Most surface
analysis must take place in vacuum, a major drawback for liquids. The technique of
time-of-flight scattering and recoil spectrometry (TOF-SARS) has been applied to...
Escherichia coli double-strand uracil-DNA glycosylase (Dug) was purified to apparent homogeneity from bacteria that were defective in uracil-DNA glycosylase (Ung). After cloning the dug gene, recombinant Dug was overexpressed, purified, and characterized with respect to activity, substrate specificity, product DNA binding, and mechanism of action. Purified Dug excised both uracil...
Numerous investigations have been made on the contribution of
butter cultures to the flavor of cultured cream butter, but production
of uniform cultured cream butter has not been possible in industry.
Therefore, it was desirable to investigate in detail the qualitative
and quantitative chemistry of the flavor of high quality...
This book is based on a project to completely annotate what is known about the function of the ~150 genes encoded by the genome of the most commonly investigated baculovirus, AcMNPV. Once the annotation was completed (summarized in Chapter 12), the material was organized into a series of chapters integrating...
The photophysical properties of two-dimensional (2D) layered van der Waals (vdW) materials, and their heterostructures are manifestly distinct from crystalline bulk materials. Recently, the discovery of new 2D vdW materials and strongly-bound interlayer excitons in these materials has created a new branch in nanoscience. As such, there are a number...
