This review article highlights the emergence of eclectic molecular design principles to realize remarkably strong electron deficient arylenediimide molecules, aspects their stability and associated applications.

Lead-free piezoelectric ceramic is a promising material for energy harvesters, as they have superior electromechanical, ferroelectric, and properties. In addition, ceramics can be blended with polymer to achieve high-flexibility polymer-ceramic composites, providing mechanical robustness stability. this context, new lead-free ferroelectric material, having the chemical formula SrTi2O5 (STO), was synthesized using high-temperature solid-state reaction. Detailed analyses of structural,...

A facile synthesis of octabromoperylene-3,4,9,10-tetracarboxylic dianhydride (Br8-PDA) (1), its diimides (Br8-PDIs) (2a–e), and bis-, tris-, tetra-amino substituted (5a–c) with six, five, four remaining substitutable Br atoms, respectively, is reported. Octabromination results in chemical/electrochemical reduction, radical anion formation, red-shifted optical properties. For the first time, diverse halogen-bonding interactions were identified PDA/PDI, which along attractive electronic...

In this article, we have discussed the recently developed synthetic routes to amplify electron‐poor nature of naphthalenediimides (NDIs) as well integration electron‐rich donor groups towards ambipolar and strongly electron donating NDIs. Non‐conventional withdrawing (EWGs) been applied, leading highly deficient Highly π‐acidic molecules with LUMO levels up –5.0 eV now realized. Cationic EWGs integrated at NDI‐core resulting in six‐electron acceptors called “electron‐sponge”. Electron like...

We report a new class of multi-electron acceptors by integrating for the first time multiple π-cations at naphthalenediimide-core.

The synthesis and isolation of two-electron reduced naphthalenediimides is reported. A doubly zwitterionic structure observed for the first time in a naphthalene moiety, which aids its stabilization.

The distribution of hemoglobin E (α₂β2^26Glu®Lys ) is mostly restricted to Northeastern India. While evaluating the patients jaundice, we came across two cases (Hb E) disorders. first case in a 22-year-old Bengali male and second Hb E/β thalassemia 5-year-old Hindu boy. family study revealed trait both parents Case 1, whereas 2, father was found have mother had β -thalassemia minor, thus confirming diagnosis. Herein, present laboratory diagnosis comparative data...

The first successful Buchwald-Hartwig reaction at the naphthalenediimide core is reported, leading to coupling of diverse secondary aromatic amines including dendritic donors. G1-dendrimer-based donor exhibit blackish color, providing access black absorbing systems. λonset values up 1070 nm was achieved, which maximum from a single NDI scaffold. These dyes also manifest multielectron reservoir properties. A total eight-redox states with band gap ∼0.95 eV accomplished.

Deficiency of factor VIII (Hemophilia A), IX B) and Von Willebrand's are the most frequent coagulation defects. The incidence inhibitors in patients deficiency is varies different regions India.

In the recent past, there has been a substantial push to increase sanitation infrastructure in India end open defecation and improve level of hygiene. The choice type sanitation, however, depends on demographic, socio-economic, tenurial, cultural surroundings, which not only impacts practices but also incidences diseases. This paper empirically analyses determinants households’ toilet facility relation between incidence diseases using National Sample Survey Office’s 76 th round survey for...

Von Willebrand disease is the most common inherited bleeding disorder with a prevalence of approximately 1% in general population. Studies available from India are limited, showing 10% vWD amongst disorders.This study aims to know and subtypes patients presenting various manifestations university hospital.We investigated 840 period August 2004 2008 for disorders.Tests performed diagnosis included platelet count, time (BT), prothrombin (PT), activated partial thromboplastin (APTT), Factor...

Myeloproliferative disorders are characterized by proliferation of one or more myeloid lineages cells. In order to assess the burden these illness for public health planning, it is important know their frequency.A study determine clinical, hematological, cytogenetic, and molecular profile in chronic leukemia (CML) patient around Eastern UP, India.Newly diagnosed follow-up adult pediatric cases myeloproliferative disorder were taken into study. Detailed history, physical, systemic examination...

A mAb-based simple, specific and rapid two-tip dipstick ELISA was developed for simultaneous detection of toxin- non-toxin-producing strains Vibrio cholerae, direct V. cholerae from rectal swabs patients environmental water samples. Rabbit polyclonal antibodies murine mAbs were raised against recombinant protein (r-protein) antigens cholera toxin B (CtxB) outer membrane W (OmpW). to both r-proteins coated individually onto the tips nitrocellulose (NC) membranes a two-tipped NC as capture...

A novel class of bifunctional molecules was synthesized integrating acridine (Ac) and redox-active naphthalenediimide (NDI) scaffolds directly through a flexible linker (en). We evaluated in vitro antiplasmodial activity, physicochemical properties, possible mode action. Theoretical studies suggested electronic segmentation between the electron-rich Ac electron-deficient NDI scaffolds. Orthogonal Ac–NDI showed activities micromolar to submicromolar range against chloroquine (CQ)-sensitive...
