A nanotrap infused ultrathin hybrid composite material for rapid and highly selective entrapment of TcO.

Tc is one of the potentially toxic radioactive substances owing to its long half-life and a high degree of environmental mobility. Hence, the sequestration of Tc from radioactive waste has become enormously important and a contemporary research priority. However, selective extraction of this species in its stable oxoanionic form (TcO ) is very challenging on account of bottlenecks such as low charge density, less hydrophilic nature, Herein, an ultrathin hybrid composite material has been strategically designed and fabricated by covalent anchoring of a chemically stable amino functionalized nanosized cationic metal-organic polyhedron with a positively charged robust ionic covalent organic framework.

A triazole-based covalent organic framework as a photocatalyst toward visible-light-driven CO reduction to CH.

Solar-light driven reduction of CO to CH is a complex process involving multiple electron and proton transfer processes with various intermediates. Therefore, achieving high CH activity and selectivity remains a significant challenge. Covalent organic frameworks (COFs) represent an emerging class of photoactive semiconductors with molecular level structural tunability, modular band gaps, and high charge carrier generation and transport within the network.

Toward Atomistic Understanding of Iron Phosphate Glass: A First-Principles-Based Density Functional Theory Modeling and Study of Its Physical Properties.

Iron phosphate glasses (IPGs) have been proposed as futuristic materials for nuclear waste immobilization and anode materials for lithium batteries. Recently, many attempts have been made to propose atomistic models of IPGs to explain their properties from an atomistic viewpoint. In this paper, we seek to produce small scale models of IPG that can be handled within the scheme of density functional theory (DFT) to study its electronic structure.

Polyethyleneimine-assisted formation of Ag-SiO hybrid microspheres for HO sensing and SERS applications.

Herein, we report a simple, cost-effective, and eco-friendly approach for producing polyethyleneimine (PEI)-assisted silver nanoparticle-supported silica microspheres through evaporation-induced assembly (EIA). The silica-PEI microspheres obtained through EIA consisted of highly trapped PEI molecules owing to their electrosorption onto oppositely charged silica colloids. The trapped PEI molecules in the microspheres played a crucial role in linking silver ions to form silver ion-PEI complexes, which were then reduced to form silver nanoparticles.

A rationale for the rapid extraction of ultra-low-level uranyl ions in simulated bioassays regulated by Mn-dopants over magnetic nanoparticles.

Although the sorption of uranyl ions and other heavy metal ions over magnetic nanoparticles is well reported, the parameters governing the sorption process over the magnetic nanoparticles have not been clearly enumerated. However, to increase the efficiency of the sorption over the surface of these magnetic nanoparticles, it is essential to understand the different structural parameters that are involved in the sorption process. The sorption of uranyl ions and other competitive ions in simulated urine samples at different pH was effectively accomplished over magnetic nanoparticles of FeO (MNPs) and Mn-doped FeO (Mn-MNPs).

Endoscopic ultrasound guided biliary drainage in surgically altered anatomy: A comprehensive review of various approaches.

Endoscopic retrograde cholangiopancreatography (ERCP) is the preferred modality for drainage of the obstructed biliary tree. In patients with surgically altered anatomy, ERCP using standard techniques may not be feasible. Enteroscope assisted ERCP is usually employed with variable success rate.

FtsZ phosphorylation brings about growth arrest upon DNA damage in .

The polymerization/depolymerization dynamics of FtsZ play a pivotal role in cell division in the majority of the bacteria. , a radiation-resistant bacterium, shows an arrest of growth in response to DNA damage with no change in the level of FtsZ. This bacterium does not deploy LexA/RecA type of DNA damage response and cell cycle regulation, and its genome does not encode SulA homologues of , which attenuate FtsZ functions in response to DNA damage in other bacteria.

An insight into the sodium-ion and lithium-ion storage properties of CuS/graphitic carbon nitride nanocomposite.

Metal sulfides are gaining prominence as conversion anode materials for lithium/sodium ion batteries due to their higher specific capacities but suffers from low stability and reversibility issues. In this work, the electrochemical properties of CuS anode material has been successfully enhanced by its composite formation using graphitic carbon nitride (g-CN). The CuS nanoparticles are distributed evenly in the exfoliated g-CN matrix rendering higher electronic conductivity and space for volume alterations during the repeated discharge/charge cycles.

Phthalimide conjugation turns the AIE-active tetraphenylethylene unit non-emissive: its use in turn-on sensing of hydrazine in solution and the solid- and vapour-phase.

Hydrazine is a vital precursor used in several pharmaceuticals and pesticide industries and upon exposure can cause severe health hazards. Herein, a new AIEgen, tetraphenylethylene phthalimide (TPE-PMI), is synthesized in a one-step solvent-free mechanochemical approach exploiting the simple condensation between TPE-NH and phthalic anhydride and used for the selective and sensitive detection of hydrazine. TPE-PMI with an AIE-active TPE-moiety is non-emissive in the solid phase by design.

Synthesis, structure and the Hirshfeld surface analysis of three novel metal-tiron coordination complexes.

Three novel metal-tiron (4,5-dihydroxy-1,3-benzenedisulfonic acid disodium salt) and other pillared ligand bpy (4,4'-bipyridyl)-centered coordination polymers of the formulae [Cd(tiron)(bpy)(HO)]·0.5(HO), 1, [Co(tiron-bpy)(bpy)(HO)]·(HO), 2, and [Ba(tiron-bpy)(HO)][solvent], 3, were successfully synthesized under hydrothermal conditions. The as-synthesized materials were well characterized by complimentary techniques such as single-crystal X-ray diffraction, powder X-ray diffraction, Fourier-transform infrared spectroscopy and thermogravimetric analysis techniques.

Case Series of Applications of Resting State Functional MRI in Brain Tumor Surgery: A Novel Technique.

 The extent of resection for brain tumors is a critical factor in determining the oncologic outcome for a patient. However, a balance between preservation of neurological function and maximal resection is essential for true benefit. Functional magnetic resonance imaging (fMRI) is one of the approaches that augments the neurosurgeon's ability to attain maximal safe resection by providing preoperative mapping.

Hypomethylating agents+venetoclax induction therapy in acute myeloid leukemia unfit for intensive chemotherapy - novel avenues for lesser venetoclax duration and patients with baseline infections from a developing country.

Both elderly acute myeloid leukemia (AML) patients and those with baseline infections, when treated with intensive chemotherapy, are associated with high induction mortality. We report 24 patients (16-newly-diagnosed, 8-relapsed/refractory) with AML deemed unfit for intensive chemotherapy (by virtue of age >60 years, ECOG-PS 3-4, or those with non-resolving infections at baseline), treated with azacytidine-venetoclax combination as induction chemotherapy. Median follow-up of the study group was 8 months.

Serous endometrial intraepithelial carcinoma: A clinico-pathological study of 48 cases and its association with endometrial polyps - A tertiary care oncology centre experience.

Background: Endometrial serous carcinoma (ESC) is an aggressive neoplasm wherein the recent studies have shown that it arises from its putative precursor namely the serous endometrial intraepithelial carcinoma (SEIC). SEIC usually arises in inactive/ atrophic endometrium but surprisingly is frequently associated endometrial polyps (EPs). The aim of this study was to assess the incidence of SEIC with or without invasion, its clinical behaviour and association with endometrial polyp.
