Molten-Salt-Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In-Situ Carbon Capture and Utilization.

The molten-salt-mediated oxidative dehydrogenation (MM-ODH) of ethane (CH) via a chemical looping scheme represents an effective carbon capture and utilization (CCU) method for the valorization of ethane-rich shale gas and concurrent mitigation of carbon dioxide (CO) emissions. Here, stepwise experimentation with LiCO-NaCO-KCO (LNK) ternary salts (i) assessed how each component of the LNK mixture impacted ethane MM-ODH performance and (ii) explored physicochemical and thermodynamic mechanisms behind melt-induced changes to ethylene (CH) and carbon monoxide (CO) yields. Of fifteen screened LNK compositions, nine exhibited ethylene yields greater than 50 % at 800 °C while maintaining CH selectivities of 85 % or higher.

Insulinoma-associated protein-1 (INSM-1) is a useful diagnostic marker for the evaluation of primary thymic neuroendocrine neoplasms: an immunohistochemical study of 27 cases.

Insulinoma-associated protein 1 (INSM1) immunohistochemistry has been established as a sensitive and reliable immunohistochemical marker for detecting neuroendocrine differentiation in tumors across various organ systems. However, this marker has not been adequately investigated in primary thymic neuroendocrine tumors. We have studied a series of 27 cases of primary neuroendocrine carcinomas of the thymus, including 3 typical carcinoids, 18 atypical carcinoids, 4 large cell neuroendocrine carcinomas, and 2 small cell carcinomas.

Lymphoepithelial Carcinoma of the Sublingual Gland: A Case Report.

Lymphoepithelial carcinoma (LEC) of the salivary gland is a rare squamous cell carcinoma. LEC commonly presents in the parotid and submandibular glands and rarely in the sublingual gland. While salivary gland LEC has a predilection for Inuit-Yupik and Chinese populations, few cases have been reported in the Hispanic population and none for sublingual glands in the English language literature.

Printable Liquid Metal Foams That Grow When Watered.

Pastes and "foams" containing liquid metal (LM) as the continuous phase (liquid metal foams, LMFs) exhibit metallic properties while displaying paste or putty-like rheological behavior. These properties enable LMFs to be patterned into soft and stretchable electrical and thermal conductors through processes conducted at room temperature, such as printing. The simplest LMFs, featured in this work, are made by stirring LM in air, thereby entraining oxide-lined air "pockets" into the LM.

One-Step Synthesis of a High Entropy Oxide-Supported Rhodium Catalyst for Highly Selective CO Production in CO Hydrogenation.

High entropy oxide (HEO) has shown to be a new type of catalyst support with tunable composition-function properties for many chemical reactions. However, the preparation of a metal nanoparticle catalyst supported on a metal oxide support is time-consuming and takes multiple complicated steps. Herein, we used a one-step glycine-nitrate-based combustion method to synthesize highly dispersed rhodium nanoparticles on a high surface area HEO.

Examination of social decision making in patients with schizophrenia using ultimatum game.

Intact decision-making skills in the social context are essential for optimal functioning in the community. Despite its significance, social decision making in schizophrenia (SCZ) has not been adequately examined. Hence, we examined social decision making in SCZ using the Ultimatum Game(UG), a neuroeconomic paradigm that involves financial transactions between a proposer and a responder to split a sum of money between them.

Cultural differences and neural correlates of cognitive insight in schizophrenia.

Cognitive insight refers to a person's ability to examine their psychotic experiences and the inferences they draw from these experiences. Several studies suggest that cultural factors influence cognitive insight and the processes involved therein; a few studies have suggested differences between Western and Asian societies. However, there are no studies on cognitive insight and its neural correlates in non-Western populations.

A facile approach for high surface area electrospun TiO2 nanostructures for photovoltaic and photocatalytic applications.

A rice-shaped TiO2-ZnO composite was prepared by electrospinning a mixture comprising the precursors of TiO2 and ZnO in polyvinyl acetate polymer dissolved in N,N-dimethyl acetamide. The electrospun nanofibers upon heat treatment in air resulted in collapse of the continuous fiber morphology and the formation of the rice-shaped TiO2-ZnO composite. The TiO2-ZnO composite was then treated with dilute acetic acid under hydrothermal conditions to etch ZnO from the TiO2-ZnO composite to get coral-shaped anisotropic TiO2.

The study was conducted to compare growth status, blood pressure, self esteem and intelligence of 200 low birthweight (LBW) and 224 normal birthweight (NBW) adolescents at 13 years of age. Intelligence scores at or below the 25th percentile (low performance) were observed among 51.4% LBW and 41.

Markers of fetal onset adult diseases.

The fetal origins hypothesis, proposes that non-communicable diseases including coronary heart disease, type 2 diabetes and hypertension originate through the responses of a fetus to undernutrition, that permanently change the structure and function of the body. Associations between low birthweight and disease in later life have been widely studied in Europe and the USA. Studies in southern India have shown that babies who are short and fat tend to become insulin deficient and have high rates of non-insulin dependent diabetes.

Markers of fetal onset adult diseases: a comparison among low birthweight and normal birthweight adolescents.

Objective: To observe and compare the markers of fetal onset adult diseases among low birthweight (<2500 grams, LBW) and normal birthweight (> or =2500 grams, NBW) babies at 16 years of age.

Methods: Comparative cross sectional analysis of two groups of cohorts followed-up at 1 year and 16 years of age at Child Development Centre (CDC), Medical College, Thiruvananthapuram. 189 LBW babies formed the study group and 213 NBW babies formed the comparison group.

In vitro generation of early-born neurons from late retinal progenitors.

Evidence suggests that, as development ensues, the competence of neural progenitors is progressively altered, such that they become fated to give rise to neurons of a particular stage. Here, we demonstrate that late retinal progenitors can give rise to retinal ganglion cells (RGCs), an example of an early-born cell type in the retina. A subset of late retinal progenitors in vitro responds to cues that favor RGC differentiation by displaying markers characteristic of RGCs.

Transplantation of ocular stem cells: the role of injury in incorporation and differentiation of grafted cells in the retina.

The incorporation of transplanted cells into the host retina is one of the prerequisites for successful cell replacement therapy to treat retinal degeneration. To test the hypothesis that injury promotes cell incorporation, stem cells/progenitors were isolated from the retina, ciliary epithelium or limbal epithelium and transplanted into the eyes of rats with retinal injury. Different stem cell/progenitor populations incorporated into traumatized or diseased retina but not into the normal retina.
