Elucidating early proton irradiation effects in metal halide perovskites via photoluminescence spectroscopy.

Metal halide perovskite (MHP) solar cells are promising aerospace power sources given their potential as inexpensive, lightweight, and resilient solar electricity generators. Herein, the intrinsic radiation tolerance of unencapsulated methylammonium lead iodide/chloride (CHNHPbICl) films was isolated. Spatially resolved photoluminescence (PL) spectroscopy and confocal microscopy revealed the fundamental defect physics through optical changes as films were irradiated with 4.

HO Mediated Photoreduction of Nitrates to Ammonia by Iron Filings under Ambient Conditions.

Herein, a simple ambient conditioned sunlight promoted photochemical reduction reaction is demonstrated for the of nitrate (NO) conversion to ammonia (NH) with the maximum conversion yield of ∼16 mM using iron filings (f-Fe) in the presence of HO. Based on a radical scavenging study of reactive species and the characterization of catalyst f-Fe before and after the reaction, a plausible mechanism has been proposed for the ambient conditioned synthesis of NH. The results associated with the NH synthesis have been verified using the N isotopic labeled nitrate (NO), which supports the simpler viability of the reported procedure.

Molecular Taxonomy Suggests Presence of Two Distinct Lineages of Blue Sheep (Pseudois nayaur) in Indian Himalayan Region.

Indian Himalayan Region (IHR) supports a plethora of biodiversity with a unique assemblage of many charismatic and endemic species. We assessed the genetic diversity, demographic history, and habitat suitability of blue sheep (Pseudois nayaur) in the IHR through the analysis of the mitochondrial DNA (mtDNA) control region (CR) and Cytochrome b gene, and 14 ecological predictor variables. We observed high genetic divergence and designated them into two genetic lineage groups, i.

Is ADDM graft practical? A comparative study to evaluate ADDM graft in third molar surgery.

Background: It has been outlined that LTM (Lower third molar) extracted from patients in which grinding, cleaning, sterilization & demineralization prove to be highly effective as graft material for filling the alveolar socket of the very same patient. These investigations aim to assess the efficiency of ADDM (Autogenous Demineralized Dentin Matrix) graft in third molar extraction sockets.

Purpose: To check the effectiveness of ADDM as graft material in extraction socket by evaluating pain, swelling, trismus, PD (Probing Depth) and bone density.

Molecular mechanisms of antiproliferative and pro-apoptotic effects of essential oil active constituents in MCF7 and T24 cancer cell lines: in vitro insights and in silico modelling of proapoptotic gene product-compound interactions.

This study aims to investigate the in vitro antiproliferative and pro-apoptotic/apoptotic potential of active constituents of essential oils on two cancer cell lines; namely, breast adenocarcinoma (MCF-7) and urinary bladder cancer (T24). Essential oils active constituents (EO-ACs) entail a spectrum of phytochemicals with widely demonstrated anticancer potential. We assessed the effects of eight essential oils active constituents on T24 and MCF-7 cell lines in both dose- (16-1024 µg/mL) and time-dependent manners.
