Abstract Metal halide perovskite nanocrystals (NCs) have emerged as highly promising light emitting materials for various applications, ranging from light‐emitting diodes (PeLEDs) to lasers and radiation detectors. While remarkable progress has been achieved in efficient stable green, red, infrared NCs, obtaining blue‐emitting NCs remains a great challenge. Here, facile synthetic approach the preparation of blue CsPbBr 3 nanoplatelets (NPLs) with treatment by an organic sulfate is reported,...
An efficient, inexpensive, environmentally friendly and high yield one-pot route to new spiro[indolo-3,10′-indeno [1,2-b]quinolin]-trione derivatives has been developed, involving three-component reaction of enaminones, N-substituted isatins Indane-1,3-dione catalyzed by FeCl3. The approach this spiro-heterocycle is noteworthy because it results in the formation three σ (two C–C one C–N) bonds a single operation, leading construction novel spiro skeleton. This method works on large scale...
Ten rare, threatened, and endangered Rhododendron species were collected from different places of altitudinal ranges starting 2,247 to 3,580 masl. Of Darjeeling Hill.

Lysozyme, like many other well-folded globular proteins, under stressful conditions produces nanoscale oligomer assembly and amyloid-like fibrillar aggregates. With engaging Raman microscopy, we made a critical structural analysis of structures lysozyme obtained from hen egg white provided quantitative estimation protein secondary structure in different states its fibrillation. A strong amide I band at 1660 cm–1 N–Cα–C stretching ∼930 clearly indicated the presence substantial amount...
X-ray scintillators based on organic chromophores have the potential to deliver low-cost radiation detection products with fast response signals. However, their relatively low performance compared that of widely used inorganic in terms attenuation and light output has limited applications.
