Constituent quarks and g 1
TLDR
In this paper, the authors review the theory and present status of the proton spin problem with emphasis on the transition between current quarks and constituent quarks in QCD, and propose a solution to the problem.Abstract:

Chemical Management for Colorful, Efficient, and Stable Inorganic–Organic Hybrid Nanostructured Solar Cells
TL;DR: This paper demonstrates highly efficient solar cells exhibiting 12.3% in a power conversion efficiency of under standard AM 1.5, for the most efficient device, as a result of tunable composition for the light harvester in conjunction with a mesoporous TiO2 film and a hole conducting polymer.
Journal ArticleDOI
Microscopic view of epitaxial metal growth: nucleation and aggregation
TL;DR: In this article, the authors reviewed the early stages of epitaxial growth and showed how the growth kinetics can be employed to create well-defined island morphologies and island arrays in a self-organization process.

Luminescence in Eu 2+ -doped Ba 2 Si 5 N 8 : fluorescence, thermoluminescence, and upconversion
TL;DR: Fluorescence emission in a series of Ba2−xEuxSi5N8 compounds was investigated in this paper, where two maxima corresponding to the two crystallographic Eu2+ sites are observed.

Additive covalent radii for single-, double-, and triple-bonded molecules and tetrahedrally bonded crystals: a summary.
TL;DR: The recent fits of additive covalent radii R(AB) = r(A) + r(B) for the title systems are reviewed and compared with alternative systems of radii by other authors or with further experimental data.
Journal ArticleDOI
The Spin Structure of the Nucleon
TL;DR: In this paper, the authors review the present understanding of QCD spin physics: the proton spin puzzle and new developments aimed at understanding the transverse structure of the nucleon.

Structure of the proton
TL;DR: A struggle to explain this seeming paradox may be leading to a clearer view of the precise laws of the proton's structure and other phenomena of high energy physics.

Effects of Topological Charge in Gauge Theories
TL;DR: In this article, the properties of topological charge in gauge theories and the physical effects which have been attributed to its existence are discussed, as well as the physical properties of the existence of topology charge.

Physics with polarized protons at HERA
TL;DR: In this article, the authors discuss the physics case for using polarized protons and electrons at the ep collider HERA and show that if a polarization of 70% can be achieved for the protons, important and partly unique measurements can be made at HERA.
