Diffusion von Spaltprodukten bei überlagerter chemischer Reaktion: Mathematische Grundlagen [PDF]

open access: yes, 1966
Die bisher veröffentlichten Untersuchungen über den Massentransport von Spaltprodukten in Graphit lassen darauf schließen, daß keine reine Diffusion vorliegt, sondern daß diese durch eine oder mehrere Reaktionen überlagert ist.

Nd:YAG laser welding of stainless steel 304 for photonics device packaging [PDF]

open access: yes, 2011
Although pulsed Nd:YAG laser welding has been widely used in microelectronics and photonics packaging industry, a full understanding of various phenomena involved is still a matter of trials and speculations.

A borane laser [PDF]

open access: yesNature Communications, 2015
Emission from electronically excited species forms the basis for an important class of light sources-lasers. So far, commercially available solution-processed blue-emitting laser materials are based on organic compounds or semiconductor nanocrystals that have significant limitations: either low solubility, low chemical- and/or photo-stability and/or ...

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

open access: yesFEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Laser ignition of an optically sensitised secondary explosive by a diode laser [PDF]

open access: yes, 2016
As a green technology, laser ignition of a relatively insensitive secondary explosive has been experimentally investigated. The explosive, hexanitrostilbene (HNS), was doped with one of two optical sensitizers, carbon black or a laser absorbing dye ...

Theory of high-harmonic generation by low-frequency laser fields.

open access: yesPhysical Review A. Atomic, Molecular, and Optical Physics, 1994
We present a simple, analytic, and fully quantum theory of high-harmonic generation by low-frequency laser fields. The theory recovers the classical interpretation of Kulander et al. in Proceedings of the SILAP III Works hop, edited by B. Piraux (Plenum,

LIGO: The laser interferometer gravitational-wave observatory [PDF]

open access: yes2006 Conference on Lasers and Electro-Optics and 2006 Quantum Electronics and Laser Science Conference, 2006
LIGO is a trio of extremely sensitive Michelson interferometers built to detect gravitational waves from space. We describe predicted sources of gravitational waves, our detectors, and the results of our recent observations.

Targeting the MDM2‐MDM4 interaction interface reveals an otherwise therapeutically active wild‐type p53 in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
This study investigates an alternative approach to reactivating the oncosuppressor p53 in cancer. A short peptide targeting the association of the two p53 inhibitors, MDM2 and MDM4, induces an otherwise therapeutically active p53 with unique features that promote cell death and potentially reduce toxicity towards proliferating nontumor cells.

Möglichkeiten zur Verbesserung der Siliereigenschaften verschiedener perennierender Gras-/ Leguminosenmischungen durch Hoch-Zucker-Gräser [PDF]

open access: yes, 2007
Herbage from legumes or legume-rich swards potentially has lower concentrations of water soluble carbohydrates (= wsc) and a higher buffering capacity (= bc) than grass grown in pure stands.
