Gewinnung von Fettsäuremethylestern aus industriellem Kaffeesatz mittels eines In‐situ‐Prozesses In Situ Process for the Synthesis of Fatty Acid Methyl Esters from Industrial Spent Coffee Grounds

open access: yesChemie Ingenieur Technik, Volume 97, Issue 1-2, Page 116-126, February 2025.
Kaffeesatz (SCG) aus der industriellen Produktion von Instant‐Kaffee enthält einen hohen Anteil an freien bzw. triglyceridisch gebundenen Fettsäuren (FA). Ein entwickelter In‐situ‐Prozess der Ver‐ und Umesterung von SCG kombiniert die Verfahrensschritte der Extraktion und chemischen Umwandlung und macht FA in Form von Fettsäuremethylestern für eine ...

A Picture of D-branes at Strong Coupling II. Spinning Partons [PDF]

open access: yes, 1998
We study the Born-Infeld D-brane action in the limit when the string coupling goes to infinity. The resulting actions is presented in an arbitrary background and shown to describe a foliation of the world-volume by strings.

Limits of the D-brane action [PDF]

open access: yes, 1999
For background geometries whose metric contain a scale $\gamma$ we reformulate the Born-Infeld D-brane action in terms of $\epsilon \equiv \gamma /(2\pi \alpha ')$.

A Review of Polyolefin‐Insulation Materials in High Voltage Transmission; From Electronic Structures to Final Products

open access: yesAdvanced Materials, Volume 36, Issue 52, December 27, 2024.
A review on polyolefin insulations in high‐voltage DC components. It contains a state of the art of current systems, techniques to measure insulation properties, and a presentation of mechanisms affecting the insulation performance, including effects of molecular structure, morphology, fillers, and impurities.

N=4 Super Yang-Mills Low-Energy Effective Action at Three and Four Loops

open access: yes, 2000
We investigate the low-energy effective action in N=4 super Yang-Mills theory with gauge group SU(n) spontaneously broken down to its maximal torus. Using harmonic superspace technique we prove an absence of any three- and four-loop corrections to non ...

Generalized Kahler geometry and gerbes

open access: yes, 2008
We introduce and study the notion of a biholomorphic gerbe with connection. The biholomorphic gerbe provides a natural geometrical framework for generalized Kahler geometry in a manner analogous to the way a holomorphic line bundle is related to Kahler ...

Poisson-Lie T-plurality of three-dimensional conformally invariant sigma models II: Nondiagonal metrics and dilaton puzzle

open access: yes, 2004
We look for 3-dimensional Poisson-Lie dualizable sigma models that satisfy the vanishing beta-function equations with constant dilaton field. Using the Poisson-Lie T-plurality we then construct 3-dimensional sigma models that correspond to various ...
