Haemophagocytic lymphohistiocytosis in pregnancy.

Dengue infection is emerging as one of the most common tropical diseases globally. It manifests in varying severity from asymptomatic to the most severe forms of the disease, characterized by coagulopathy, increased vascular fragility, and permeability (dengue haemorrhagic fever) that may progress to hypovolaemic shock (dengue shock syndrome). For atypical manifestations, a new terminology known as expanded dengue syndrome (EDS) was introduced.

In Situ Decoration of Gold Nanoparticles on Graphene Oxide via Nanosecond Laser Ablation for Remarkable Chemical Sensing and Catalysis.

Gold decorated graphene-based nano-hybrids find extensive research interest due to their enhanced chemical catalytic performance and biochemical sensing. The unique physicochemical properties and the very large surface area makes them propitious platform for the rapid buildouts of science and technology. Graphene serves as an outstanding matrix for anchoring numerous nanomaterials because of its atomically thin 2D morphological features.

In Situ Synthesis of Silver Nanospheres, Nanocubes, and Nanowires over Boron-Doped Graphene Sheets for Surface-Enhanced Raman Scattering Application and Enzyme-Free Detection of Hydrogen Peroxide.

An effective in situ synthesis strategy is demonstrated for the preparation of silver nanostructures (nanospheres (NSs), nanocubes (NCs), and nanowires (NWs)) on the surface of boron-doped graphene (BG). Further, these functional nanomaterials are employed for the surface-enhanced Raman scattering (SERS) and non-enzymatic electrochemical detection of HO. The results confirm the superior performance of BG-Ag nanostructures as SERS platform.

Boron doped graphene wrapped silver nanowires as an efficient electrocatalyst for molecular oxygen reduction.

Metal nanowires exhibit unusually high catalytic activity towards oxygen reduction reaction (ORR) due to their inherent electronic structures. However, controllable synthesis of stable nanowires still remains as a daunting challenge. Herein, we report the in situ synthesis of silver nanowires (AgNWs) over boron doped graphene sheets (BG) and demonstrated its efficient electrocatalytic activity towards ORR for the first time.
