Sub-2W tunable laser based on silicon photonics power amplifier.

High-power tunable lasers are intensely pursued due to their vast application potential such as in telecom, ranging, and molecular sensing. Integrated photonics, however, is usually considered not suitable for high-power applications mainly due to its small size which limits the energy storage capacity and, therefore, the output power. In the late 90s, to improve the beam quality and increase the stored energy, large-mode-area (LMA) fibers were introduced in which the optical mode area is substantially large.

Fabrication of Oro-Dispersible Sodium Valproate-Loaded Nanofibrous Patches for Immediate Epileptic Innervation.

Epilepsy is one of the oldest neurological disorders discovered by mankind. This condition is firmly coupled with unprovoked seizures stimulated by irrepressible neuroelectrical blasts. Orally taken valproate family has been employed for prophylactic management; however, oral administration is not applicable for critical scenarios, thus calling for medication routes fulfilling necessities of immediate innervation.

Synthesis of Iron(IV) Alkynylide Complexes and Their Reactivity to Form 1,3-Diynes.

The isolation of thermally unstable and highly reactive organoiron(IV) complexes is a challenge for synthetic chemists. In particular, the number of examples where the C-based ligand is not part of the chelating ligand remains scarce. These compounds are of interest because they could pave the way to designing catalytic cycles of bond forming reactions proceeding via organoiron(IV) intermediates.

Defective kinase activity of IKKα leads to combined immunodeficiency and disruption of immune tolerance in humans.

IKKα is a multifunctional serine/threonine kinase that controls various biological processes, either dependent on or independent of its kinase activity. However, the importance of the kinase function of IKKα in human physiology remains unknown since no biallelic variants disrupting its kinase activity have been reported. In this study, we present a homozygous germline missense variant in the kinase domain of IKKα, which is present in three children from two Turkish families.

Pushing the tuning limits of femtosecond Yb-based solid-state lasers to 1 µm: a Yb:YVO laser tunable down to 1004 nm.

We have obtained what we believe to be the shortest fs tuning wavelength (1004 nm) from a Yb-based solid-state laser system. As the working horse, we have chosen Yb:YVO due to its blueshifted gain spectrum. While using a single 10 W 952 nm diode for pumping and a semiconductor saturable absorber mirror (SESAM) for mode-locking, we have achieved 266 fs long pulses with up to 1.
