Samlingen teologisk litteratur med signum TF finns vid Teologiska biblioteket. Vid huvudbiblioteket finns teologisk litteratur under signum HB IIc1. Många tusen volymer teologisk litteratur har genom åren donerats till akademibiblioteket och donationer görs allt fortfarande. Bland tidigare donatorer kan som exempel nämnas prostinnan Hortense Grönstrand, häradshövding J.V. Brummer, vicehäradshövding Jon Hartman samt prostarna Konrad Ahlman, Karl Anders Troberg, Viktor Roslin, Theodor von Pfaler, Werner Wirén och C.H. Ekblom. Den teologiska litteraturen söks med sökfunktionen Signum och söktermen TF. Litteratur tryckt före 1980 söks manuellt i en kortkatalog vid Teologiska biblioteket. Retroaktiv inmatning i Alma gör att litteratur tryckt mellan 1830 och 1979 med tiden blir sökbar i Alma.

Adaptação no método do peso da gota para determinação da tensão superficial: um método simplificado para a quantificação da CMC de surfactantes no ensino da química

The discussion based on surfactant cleaning action is commonly used in chemistry classrooms for the comprehension of theoretical concepts related to surface tension and micelle formation. The experimental quantification of surface tension of aqueous solutions of surfactants provides the practical instruments for this discussion. The present paper describes a simplification on the common apparatus employed for the drop-weight method, making the determination of surface tension accessible to any chemistry lab. The surface tension of various liquids and the critical micelle concentration, CMC, of three commercial surfactants were measured with this modified method, and proved to be consistent with literature values.

Control and femtosecond time-resolved imaging of torsion in a chiral molecule

We study how the combination of long and short laser pulses can be used to induce torsion in an axially chiral biphenyl derivative (3,5-difluoro-3 ,5 -dibromo-4 -cyanobiphenyl). A long, with respect to the molecular rotational periods, elliptically polarized laser pulse produces 3D alignment of the molecules, and a linearly polarized short pulse initiates torsion about the stereogenic axis. The torsional motion is monitored in real-time by measuring the dihedral angle using femtosecond time-resolved Coulomb explosion imaging. Within the first 4 picoseconds (ps), torsion occurs with a period of 1.25 ps and an amplitude of 3◦ in excellent agreement with theoretical calculations. At larger times, the quantum states of the molecules describing the torsional motion dephase and an almost isotropic distribution of the dihedral angle is measured.We demonstrate an original application of covariance analysis of two-dimensional ion images to reveal strong correlations between specific ejected ionic fragments from Coulomb explosion. This technique strengthens our interpretation of the experimental data
