Effect of Flux and Co-doping on Photoluminescence Properties of ZnSiO:Eu Red Phosphors for Blue LED Excitable White LED Applications.

Eu activated ZnSiO red phosphor synthesized by pyrolysis technique at 1000ºC for one hour is reported. Upon excitation by 394 nm and 464 nm, the phosphor displays a distinct red emission peaking around 614 nm, a characteristic of f-f electronic transitions involving Eu ions.Incorporating alkali metal ions such as Li, Na and K into ZnSiO:Eu phosphor led to a remarkable increase in photoluminescence (PL) intensity.

GdO-modulated borate glass for the enhancement of near-infrared emission energy transfer from Gd to Nd.

(LiO)(SrO)(NdO)(BO)(GdO), where = 0, 3, 5, 7, and 10 mol%, glass was melt-quenched to test it as a laser source in the near-infrared (NIR) region. The structural modification, absorption spectra, Judd-Ofelt (J-O) parameters, luminescence spectra, radiative laser parameters, lifetimes, XRD, and FTIR spectra were studied. Luminescence spectra excited at = 584 nm revealed the highest intensity peak at 1073 nm due to the transition of F → I.

The research method used standard melt-quench and was stimulated by a laser diode (808 and 980 nm).

Dopamine D1-like receptors modulate synchronized oscillations in the hippocampal-prefrontal-amygdala circuit in contextual fear.

Contextual fear conditioning (CFC) is mediated by a neural circuit that includes the hippocampus, prefrontal cortex, and amygdala, but the neurophysiological mechanisms underlying the regulation of CFC by neuromodulators remain unclear. Dopamine D1-like receptors (D1Rs) in this circuit regulate CFC and local synaptic plasticity, which is facilitated by synchronized oscillations between these areas. In rats, we determined the effects of systemic D1R blockade on CFC and oscillatory synchrony between dorsal hippocampus (DH), prelimbic (PL) cortex, basolateral amygdala (BLA), and ventral hippocampus (VH), which sends hippocampal projections to PL and BLA.

Hazardous radiation protective glasses for medical and research laboratories.

In the current study, the bismuth oxide (BiO) content was inter-substituted with gadolinium oxide (GdO) in sodium borate glass. Glass sample density and molar volume values show a reverse trend. The optical transparent radiation shielding glasses are more commonly used materials in hospitals or any hazardous radiation working environments, the glasses used in this work are more emphasized on their superior transmittance and acceptable for shielding materials for commercial purposes.

The influence of CeF on radiation hardness and luminescence properties of GdO-BO glass scintillator.

The effect of CeF concentration and γ-irradiation on the physical, optical and luminescence properties of GdO-BO-CeF glasses were studied in this work. Before irradiation, the addition of CeF in glass degraded the network connectivity observed from FTIR and possibly created the non-bridging oxygen (NBO) in glass structure. This NBO caused the reduction of Ce/Ce ratio in XANES, the red-shift in transmission spectra and the raise of refractive index with addition of CeF content.

Sex differences in auditory fear discrimination are associated with altered medial prefrontal cortex function.

The increased prevalence of post-traumatic stress disorder (PTSD) that is observed in women may involve sex differences in learned fear inhibition and medial prefrontal cortex (mPFC) function. PTSD is characterized by fear overgeneralization involving impaired fear regulation by safety signals. We recently found that males show fear discrimination and females show fear generalization involving reduced safety signalling after extended fear discrimination training.
