An innovative, reflection-based localized surface plasmon resonance (LSPR) fiber-optic sensor has been developed and demonstrated to detect the concentration of several heavy metal lead ions in an aqueous solution. By using a self-assembling technique, gold nanoparticles (Au NPs) have immobilized on optical fiber functionalized with 1,1-Mercaptoundecanoic acid [MUA; HS(CH <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> )...

Recently CERN has discovered three new exotic particles in LHCb. The particle are $T_{cso}$ $(2900)^{++}$, a doubly charged tetraquark with quark configuration (csu$\overline{d}$), $(2900)^{0}$, neutral (cds$\overline{u}$) and pentaquark $P_{\psi s}$ $(4338)^{0}$ (c$\overline{c}$ uds) which is first observed strange its configuration. discovery of these subatomic exciting the nature interaction constituent quarks need to be understood for multiquark states. Diquark one most important...
