- This study investigates the influence of surface-modified fly ash particles on the fire behavior of polyamide 6 (PA6) composites containing two types of flame retardants: melamine polyphosphate (MPP) and aluminum diethyl phosphinate (AlPi). The objective was to evaluate how interfacial modification of fly ash using amino-silane (APTES), glycidoxy-silane (GPTES), or titanate coupling agents affects dispersion, thermal stability, and combustion performance. A series of 18 formulations containing up to 25 wt% of additives was prepared by melt compounding and characterized by thermogravimetric analysis (TGA) and cone calorimetry. TGA results showed that MPP-based systems favored char formation, with residues up to 21%, whereas AlPi provided higher thermal stability (T% ≈ 445 °C). The incorporation of untreated or surface-treated fly ash improved both thermal stability and char yield, depending on the nature of the coupling agent. Cone calorimeter results confirmed a strong synergistic effect between flame retardants and fly ash. The peak heat release rate (pHRR) decreased by 65-75% compared to neat PA6, while total heat release (THR) and mass loss were also significantly reduced. Titanate-modified fly ash showed the most homogeneous dispersion and provided the highest residue and lowest pHRR values. Energy-dispersive X-ray (EDX) analyses confirmed enhanced phosphorus retention in the residues (up to 100%), evidencing the formation of stable inorganic species and protective ceramic-like structures. These results demonstrate that surface-modified fly ash can act as an efficient synergistic additive in PA6 flame-retardant formulations, simultaneously improving fire performance and promoting the valorization of industrial by-products for sustainable polymer design. - Source: PubMed

Batistella MarcosMasarra Nour-AlhodaXenopoulos ConstantinosLopez-Cuesta José-Marie - The high water solubility of Ammonium polyphosphate (APP) limits its application in paper. In this paper, APP coated with cellulose acetate butyrate (CAB) was synthesized, and the intrinsic flame-retardant paper was prepared in cooperation with aluminum diethyl hypophosphite (AlPi). It was found that the original APP was square with smooth surface. Its surface became rough after CAB microencapsulation, and the electronegativity and water solubility were significantly reduced. When the dosage of APP was 20 wt% with in-pulp addition, compared with Kraft/APP, the limiting oxygen index (LOI) value of Kraft/APP/10%AlPi increased from 26.8% to 27.3%, while that of Kraft/10wt%CAB@APP/10%AlPi increased to 31.2%. Meanwhile, the peak heat release rate (pHRR), total heat release (THR) and effective heat of combustion (EHC) of Kraft/APP/10%AlPi decreased by 73.2%, 5.2% and 51.1%, respectively; that of Kraft/CAB@APP/10%AlPi were further reduced by 78.6%, 10.4% and 54.6%, respectively. The ID/IG values of Kraft/APP, Kraft/APP/10%AlPi and Kraft/CAB@APP/10%AlPi were 1.54, 1.41 and 0.97, respectively, meaning that the residual char layer of Kraft/CAB@10%APP/AlPi contained the highest content of graphitic carbon. Therefore, the synergistic effect of APP and AlPi significantly improved the flame retardancy of the cellulosic paper, and the flame-retardant performance was further improved after APP was coated with CAB. - Source: PubMed

Zhang ShengquanWang ZhangyiXu LingZhu FengLiu KexinXia Xinxing - This is a case report of primary angle-closure glaucoma (PACG) with persistent high intraocular pressure (IOP) despite patent laser peripheral iridotomy (LPI) and treated with argon laser peripheral iridoplasty (ALPI) possibly due to plateau iris syndrome. A 49-year-old gentleman with underlying hypertension, subclinical hypothyroidism, seizure, and ocular history of bilateral normotensive glaucoma (NTG) on topical latanoprost 0.005% every night (ON) presented with acute onset of left eye pain and redness. His IOP was found to be high with shallow anterior chamber depth and the presence of mild cataract. He was initially diagnosed with bilateral eye PACG and started with four topical antiglaucoma medications; subsequently, LPI was commenced. At subsequent follow-up, the patient reported persistent occipital headache. The IOP remained high despite compliance with all topical medications and having the enlarged patent PI over both eyes. Ultrasound biomicroscopy (UBM) was done and showed the possibility of plateau iris syndrome. He was treated with ALPI, and the IOP was reducing in trend; however, it still did not reach the optimum level. He subsequently underwent left eye phacoemulsification with intraocular lens (IOL) implantation. IOP of both eyes subsequently was able to reach the optimum level with a reduction in the number of antiglaucoma eyedrops used. Managing plateau iris syndrome may require a combination of therapies to effectively lower the IOP. ALPI may not solely be as effective as its combination with cataract removal surgery in managing plateau iris syndrome. - Source: PubMed

Nuñez Annabelle VFlewelling KateVardell EmilyAlpi Kristine M - Applying phosphate oxygen isotopes (δO) to identify sediment phosphorus (P) sources and its recycling is still challenging due to poor understanding in δO variations of sediment P pools and their driving mechanisms. Here, we analyzed the δO in inorganic P (P) pools of sediment cores and varied P sources from Lake Dianchi and Lake Erhai in the Yunnan-Guizhou Plateau, Southwest China. The δO values of sediment detrital P (Det-P, nonbioavailable P) were consistent with those of watershed soils (within ∼0.4-0.6‰), indicating that the δO of sediment Det-P inherits the δO of soil Det-P. The δO values of aluminum-bound P (Al-P) and authigenic P (Auth-P) in sediment were close to or within the δO equilibrium (δO) ranges, implying oxygen isotopic exchange equilibrium between phosphate and ambient water prior to the formation of sediment Al-P and Auth-P. However, the δO of iron oxide-bound P (Fe-P) in sediment was lighter (∼3‰) than δO, retaining the negative isotopic signal of organic P (P) remineralization. Furthermore, P NMR and metagenomic analysis indicated that microbial-mediated P mineralization and P recycling are the driving factors for δO changes in sediment Fe-P, Al-P, and Auth-P. These integrated insights deepen our understanding of the biogeochemical cycling for sedimentary P. - Source: PubMed
