Effect of Pressure on The Valency of Ytterbium in Ytterbium Monochalcogenides

Amrit Research Journal
When pressure is applied then properties of material change due to the alteration of of valency. Several effects of pressure on the characteristics of material have been investigated. This study was focused at finding the change in valency as a function of pressure of Ytterbium Monochalcogenides YbX (X=S, Se and T).

A new design approach for fibre DFB lasers with improved efficiency [PDF]

, 2004
The standard DFB laser optimisation method is critically investigated and a new design approach based on the effective cavity length is presented. By applying this method in a Erbium-Ytterbium co-doped fibre, pump-to-signal conversion ratio is increased ...

Engineering Oncolytic Virus‐Armed Macrophages for Enhanced Cancer Immunotherapy

Advanced Science, EarlyView.
ZIFOA‐M is engineered by conjugating oncolytic adenovirus‐loaded ZIF‐8 nanoparticles onto macrophage surfaces via bioorthogonal chemistry. Upon tumor infiltration, the platform releases OA to downregulate CD47/CD24 on tumor cells, restoring macrophage phagocytosis.

Ytterbium-doped fibre amplifiers

, 1997
The ytterbium-doped fiber amplifier offers a number of attractive features, including a broad-gain bandwidth and a high efficiency, due in large part to its freedom from various competing processes seen in other rare-earth dopants.

Engineering Neuronal Network Connectivity Through Precise and Scalable Electrical Modulation

Advanced Science, EarlyView.
This study presents a scalable all‐electrical method for precise neuronal‐circuit reconfiguration based on high‐density microelectrode arrays. By employing biologically inspired plasticity rules, targeted connectivity changes were successfully induced and quantified across diverse neuronal preparations.

Light‐Switched Mesenchymal Stem Cells for In Situ Exosome Amplification in Craniofacial Bone Defect Reconstruction

Advanced Science, EarlyView.
Light‐switchable MSCs (MSC‐UCNPs) were constructed by intracellular incorporation of UCNPs. Upon 980 nm irradiation, UCNPs emitted localized ultraviolet light (365 nm), activating the ROS/HEXB/LAMP1 signaling pathway to suppress lysosome–multivesicular body fusion and thereby enhance exosome biogenesis. Embedded within an injectable hydrogel, MSC‐UCNPs
