Photo-thermal conversion properties of MXene/metal-organic-frameworks-based nanofluids for solar energy harvesting.

This study focuses on enhancing solar energy capture efficiency by introducing innovative hybrid nanofluids for use in solar thermal collectors, whose performance largely depends on the absorption properties of the working fluid. The newly developed hybrid nanofluids, MXene/NH2-UiO66 (Zr) (noted as MX/UO66) and MXene/MIL-88B (Fe) (noted as MX/ML88), were synthesized using an in-situ solvothermal method, combining annealed Ti3C2Tx MXenes with water-stable metal-organic frameworks (MOFs). These nanofluids achieved high efficiency at low concentrations, providing both economic and performance benefits.

Vitamin E improves oxidative stress, apoptosis, and steroidogenesis impairment in glyphosate-induced mice.

Background: Glyphosate (Gly) is a nonselective pesticide with high potential to toxic effects on the reproductive system. Recent studies suggest that Vitamin E can indeed have a positive impact on the reproductive system, while Gly, a nonselective pesticide, has been linked to significant risks of toxicity on reproductive health. It's crucial to be mindful of the potential impacts of such substances on the reproductive system.

PD-DEM hybrid modeling of leading edge erosion in wind turbine blades under controlled impact scenarios.

This paper addresses the critical issue of leading edge erosion (LEE) on modern wind turbine blades (WTBs) caused by solid particle impacts. LEE can harm the structural integrity and aerodynamic performance of WTBs, leading to reduced efficiency and increased maintenance costs. This study employs a novel particle-based approach called hybrid peridynamics-discrete element method (PD-DEM) to model the impact of solid particles on WTB leading edges and target material failure accurately.

Dual modification of reverse osmosis membranes with NH-MIL-125 and functionalised multiwalled carbon nanotubes for enhanced nanoplastic removal.

The present study describes a novel double-modified strategy for developing high-performance thin-film composite reverse osmosis (TFC-RO) membranes by incorporating titanium-based metal organic frameworks (NH-MIL-125) and functionalised multiwalled carbon nanotubes (MWCNTs) into the support layer and selective layer, respectively. Initially, the support layer was subjected to successive modifications using NH-MIL-125 mixed with polysulfone (PSF) in dimethylformamide DMF solution to investigate their impact on the performance and properties of the support layer and resultant TFC-RO membranes. Results indicated that the new structure of the modified support layer had significant influences on the developed TFC-RO membranes.

Electromembrane extraction using biodegradable deep eutectic solvents and agarose gel as green and organic solvent-free strategies for the determination of polar and non-polar bases drugs from biological samples: A comparative study.

Two modes of electromembrane extraction (EME) were evaluated in this work, one using deep eutectic solvents (DESs) as liquid membrane, and another was gel electromembrane extraction (G-EME) based on solid agarose membrane. Both EME modes have eliminated organic solvents and are recognized as green strategies. Unlike classic EME in which polypropylene membrane and organic extracting solvents play an essential role in the extraction process, new modes of EME are based on biodegradable membranes and aqueous extracting solutions.

Human thumb consists of three phalanges and lacks metacarpal? A morphometric study on the long bones of the hand.

Purpose: For many years, it was thought that the thumb consists of just two phalanges that differentiate it from the other four medial triphalangeal fingers. But there are some old reports that few former scientists believed the thumb has three phalanges and it lacked a metacarpal, and the thumb metacarpal is a phalanx. So this anthropometric study was carried out by investigating the morphology of the long bones of the hand and correlations between the thumb metacarpal and other miniature long bones of the hand.

Enrichment of psychotropic drugs using rhamnolipid bioaggregates after electromembrane extraction based on an agarose gel using a rotating electrode as a green and organic solvent-free strategy.

We here present an efficient approach for the tandem extraction of psychotropic drugs using biodegradable materials. In this regard, gel electromembrane extraction (G-EME) was combined with the emulsification-based microextraction (ME) technique by rhamnolipid bioaggregates as a green extraction approach. The tandem extraction technique consists of two stages: (i) extraction of psychotropic drugs from human urine samples to the acceptor phase situated on the other side of the agarose gel membrane, and (ii) transfer of analytes from the acceptor phase into a colloidal phase of rhamnolipid biosurfactants.

Fetal lower urinary tract obstruction: What should we tell the prospective parents?

Fetal lower urinary tract obstruction (LUTO), which often results in marked perinatal morbidity and mortality, is caused by a heterogeneous group of anatomical defects that lead to blockage of the urethra. The classic prenatal presentation of LUTO includes megacystis with hydronephrosis. While mild forms of the disease can be associated with favorable outcomes, more severe disease commonly leads to dysplastic changes in the fetal kidneys, and ultimately oligohydramnios, which can result in secondary pulmonary hypoplasia and renal failure at birth.
