Biobased Furfurylated Poplar Wood for Flame-Retardant Modification with Boric Acid and Ammonium Dihydrogen Phosphate

Furfurylated wood exhibits excellent dimensional stability and corrosion resistance,making it a promising material for constructing buildings,but it is highly flammable.Herein,flame-retardant furfurylated poplar wood was produced via a two-step process utilizing boric acid(BA)and ammonium dihydrogen phosphate(ADP)as flame-retardant components,and biomass-derived furfuryl alcohol(FA)as a modifier.The acidity of BA and ADP allowed them to catalyze the polymerization of FA,which formed a cross-linked network that immobilized BA and ADP inside the wood.The addition of BA/ADP substantially delayed the time to ignition from 10 to 385 s and reduced the total heat release and total smoke release by 58.75%and 77.31%,respectively.Analysis of the pyrolysis process showed that the decomposition products of BA and ADP protected the underlying furfurylated wood and diluted combustible gases.This method significantly improved the fire retardancy and smokeless properties of furfurylated wood,providing promising prospects for its application as an engineering material.

Dietary bile acid supplementation in weaned piglets with intrauterine growth retardation improves colonic microbiota,metabolic activity,and epithelial function

Background Intrauterine growth retardation(IUGR)is one of the major constraints in animal production.Our previ-ous study showed that piglets with IUGR are associated with abnormal bile acid(BA)metabolism.This study explored whether dietary BA supplementation could improve growth performance and colonic development,function,micro-biota,and metabolites in the normal birth weight(NBW)and IUGR piglets.A total of 48 weaned piglets(24 IUGR and 24 NBW)were allocated to four groups(12 piglets per group):(i)NBW group,(ii)NBW+BA group,(iii)IUGR group,and(iv)IUGR+BA group.Samples were collected after 28 days of feeding.Results The results showed that dietary BA supplementation increased the length and weight of the colon and colon weight to body weight ratio,while decreased the plasma diamine oxidase(DAO)concentration in the NBW pig-lets(P<0.05).Dietary BA supplementation to IUGR piglets decreased(P<0.05)the plasma concentrations of D-lactate and endotoxin and colonic DAO and endotoxin,suggesting a beneficial effect on epithelial integrity.Moreover,dietary BA supplementation to NBW and IUGR piglets increased Firmicutes abundance and decreased Bacteroidetes abundance(P<0.05),whereas Lactobacillus was the dominant genus in the colon.Metabolome analysis revealed 65 and 51 differential metabolites in the colon of piglets fed a diet with/without BA,respectively,which was associated with the colonic function of IUGR piglets.Furthermore,dietary BA supplementation to IUGR piglets upregulated the expressions of CAT,GPX,SOD,Nrf1,IL-2,and IFN-γin colonic mucosa(P<0.05).Conclusions Collectively,dietary BA supplementation could improve the colonic function of IUGR piglets,which was associated with increasing proportions of potentially beneficial bacteria and metabolites.Furthermore,BA shows a promising application prospect in improving the intestinal ecosystem and health of animals.

Intrauterine growth retardation affects liver bile acid metabolism in growing pigs:effects associated with the changes of colonic bile acid derivatives

Background:Intrauterine growth retardation(IUGR)is associated with severely impaired nutrient metabolism and intestinal development of pigs.Our previous study found that IUGR altered intestinal microbiota and metabolites in the colon.However,the consequences of IUGR on bile acid metabolism in pigs remained unclear.The present study aimed to investigate the bile acid metabolism in the liver and the profile of bile acid derivatives in the colon of grow-ing pigs with IUGR using bile acid targeted metabolomics.Furthermore,we determined correlations between colonic microbiota composition and metabolites of IUGR and normal birth weight(NBW)pigs at different growth stages that were 7,21,and 28-day-old,and the average body weight(BW)of 25,50,and 100 kg of the NBW pigs.Results:The results showed that the plasma total bile acid concentration was higher(P<0.05)at the 25 kg BW stage and tended to increase(P=0.08)at 28-day-old in IUGR pigs.The hepatic gene expressions related to bile acid synthe-sis(CYP7A1,CYP27A1,and NTCP)were up-regulated(P<0.05),and the genes related to glucose and lipid metabolism(ATGL,HSL,and PC)were down-regulated(P<0.05)at the 25 kg BW stage in IUGR pigs when compared with the NBW group.Targeted metabolomics analysis showed that 29 bile acids and related compounds were detected in the colon of pigs.The colonic concentrations of dehydrolithocholic acid and apocholic acid were increased(P<0.05),while isodeoxycholic acid and 6,7-diketolithocholic acid were decreased(P<0.05)in IUGR pigs,when compared with the NBW pigs at the 25 kg BW stage.Moreover,Spearman’s correlation analysis revealed that colonic Unclassified_[Mogi-bacteriaceae],Lachnospira,and Slackia abundances were negatively correlated(P<0.05)with dehydrolithocholic acid,as well as the Unclassified_Clostridiaceae abundance with 6,7-diketolithocholic acid at the 25 kg BW stage.Conclusions:These findings suggest that IUGR could affect bile acid and glucolipid metabolism in growing pigs,especially at the 25 kg BW stage,these effects being paralleled by a modification of bile acid derivatives concentra-tions in the colonic content.The plausible links between these modified parameters are discussed.

Halogen-Free Flame Retarded Poly(Lactic Acid)with an Isosorbide-Derived Polyphosphonate

Fabrication of flame retardants from renewable biomass has aroused extensive interest over the past decade.This work reported a synthesis of isosorbide-derived polyphosphonate(PICPP)as an anti-flammable agent for poly(lactic acid)(PLA).The presence of PICPP notably declined the storage modulus of PLA/PICPP owing to the declined molecular weight of PLA catalyzed by the presence of PICPP.PLA and PLA/PICPP thermally degraded in one stage under either air or nitrogen atmosphere.With increasing the amount of PICPP,the onset thermal decomposition temperature of PLA/PICPP was decreased gradually,owing to the earlier decomposition of PICPP.With only 10 wt%of PICPP,PLA/PICPP-10 achieved a high limiting oxygen index of 30.0%and UL-94 V-0 classification,manifesting that PICPP was an efficient anti-flammable agent for PLA.The inclusion of 15 wt%PICPP also caused 33%and 16%decline in PHRR and THR of PLA,respectively.TG-IR results clarified that PLA/PICPP produced the less typical pyrolysis products especially flammable carbonyls than PLA,which may account for the suppressed PHRR and THR values of PLA/PICPP.

Synergistic effect of MXene on the flame retardancy and thermal degradation of intumescent flame retardant biodegradable poly(lactic acid)composites

The effect of Ti3C2 MXene nanosheets on the intumescent flame retardant(IFR)poly(lactic acid)(PLA)composites was investigated among a series of PLA/IFR/MXene,which were prepared by melt blending 0-2.0 wt%MXene,10.0 wt%-12.0 wt%IFR and PLA together.The results of limiting oxygen index(LOI)and vertical burning(UL-94)discover that the combination of 0.5 wt%MXene and 11.5 wt%IFR synergistically improves the fire safety of PLA to reach UL-94 V-0 rating with LOI value of 33.0%.The PLA/IFR/MXene composites perform an obvious reduction in peak of heat release rate(HRR)in cone calorimeter tests(CCTs).Furthermore,the carbon residues after CCTs were characterized by scanning electron microscope(SEM),laser Raman spectroscopy(LRS),X-ray diffraction(XRD)and X-ray photoelectron spectroscopy(XPS).It is demonstrated that both the titanium composition of the MXene structure and the characteristics of the two-dimensional material enhance the PLA/IFR/MXene composite materials’ability to produce a dense barrier layer to resist burnout during thermal degradation.

Effect of Dietary Folic Acid Supplementation on Growth Performance and Hepatic Protein Metabolism in Early-Weaned Intrauterine Growth Retardation Piglets

To investigate the effects of dietary supplementation with folic acid on growth performance, hepatic protein metabolism and serum biochemical indices of early-weaned intrauterine growth retardation （IUGR） piglets, 24 male （Durocx （LandracexYorkshire）） weaned （14-d-old） IUGR piglets were randomly divided into 3 treatments with 8 replicates of 1 piglet per replicate. The piglets in each treatment were fed basal diet supplementation with either 0 （control）, 5 and 10 mg kg^-1 folic acid. The trial lasted for 21 d. Dietary folic acid supplementation reduced average daily feed intake （ADFI） （P〈0.05）. In addition, the average daily gain （ADG） in 10 mg kg^-1 folic acid group was significantly decreased （P〈0.01） and the ratio of feed：gain （F/G） increased slightly （P〉0.05）. Serum folic acid concentration increased （P〈0.01） with increasing folic acid inclusion, however, serum homocysteine concentration decreased significantly （P〈0.01）. Enhanced serum urine nitrogen （SUN） and diminished serum total protein （TP） as well as liver TP content were observed in 10 mg kg^-1 folic acid group （/＇〈0.05）. Furthermore, the relative mRNA expressions of insulin-like growth factor 1 （IGF-1） and mammalian target of rapamycin （m-TOR） in liver were respectively tended to reduce （P=0.06） and significantly downregulated （P〈0.05） in 10 mg kg1 group, in compared with 5 mg kg1 group. However, when compared with control group, folic acid supplementation had no significant effect on the mRNA abundance of IGF- 1 and m-TOR. The results indicated that supplementation with 10 mg kg-I folic acid impaired growth performance and hepatic protein metabolism of early-weaned IUGR piglets while 5 mg kg-~ folic acid enriched diet exerted limited positive effects.

Novel Bio-based Flame Retardant Systems Derived from Tannic Acid

In this study,tannic acid(TA)was investigated as flame retardant agent for PLA.Different strategies to modify its thermal degradation pathway have been explored in order to improve its charring effect.The first one consists in combining TA with organomodified montmorillonite(oMMT),and enables limiting the thermo-oxidative degradation of TA and promoting the formation of an effective char layer.Flame-retardant(FR)behavior of PLA-based composition has been found to be positively impacted by this combination since a reduction of the peak of Heat Release Rate(PHRR),more important than the value recorded when oMMT and tannic acid are used separately,has been obtained.The second strategy,in which tannic acid was associated with a biosourced phosphorousbased compounds,i.e.metallic phytate salt,evidenced another alternative allowing enhancing TA flame retardant effect at 30 wt%loading content.The third and last strategy explored aims to chemically modify TA via a chemical grafting of phosphoric acid groups.This phosphorylated TA was shown to present the most effective flame-retardant(FR)effect.However,an important reduction of PLA molecular weight was observed.

Preparation and Properties of Bio-Based Flame Retardant L-APP/Poly(L-lactic acid)Composites

Poly(L-lactic acid)(PLLA)is a thermoplastic material with complete degradability,high biocompatibility and excellent mechanical properties.It can replace petroleum-based polymers are currently being used in the fields of packaging,agriculture,textiles,medical and so on.However,PLLA’s extremely flammability greatly limits its wider application.An bio-based flame retardant L-APP/PLLA composites was prepared by melt blending of the L-APP and PLLA.The morphology,impact properties,thermal properties and flame retardant properties of composites were investigated by field emission scanning electron microscope(SEM),impact tester,differential scanning calorimeter(DSC),thermogravimetric analyzer(TGA),limiting oxygen indexer(LOI)and horizontalvertical burning tester.The results showed that the degree of crystallization(X_(c))and LOI of L-APP/PLLA composites increased as increasing of L-APP content.What’s more,the impact strength first increased and then decreased,the glass transition temperature(T_(g))and melting temperature(T_(m))do not changed significantly.The impact strength of composites was 9.1 kJ/m^(2) at a 5 wt%loading for L-APP,which was the highest level.When the content of L-APP was 20%,the LOI was 30.8%,the Xc was 42.3%and the UL-94 level was V-0.This research can promote the value-added utilization of lignin and the application of PLLA in the fields of flame retardant materials.

基于Gaussian、ECOSAR模型的紫外/次氯酸体系降解含卤阻燃剂的产物预测与毒性评估

含卤阻燃剂广泛应用于各类电子产品的生产,难降解且具有生物毒性.在生产和使用过程中,部分含卤阻燃剂会残留在水体并排放到水环境造成累积污染,威胁水环境安全,亟需探寻有效的降解去毒方法.本研究通过Gaussian与ECOSAR模型预测了四氯双酚A(TCBPA)、四溴双酚A(TBBPA)、十溴二苯乙烷(DBDPE)等3种典型含卤阻燃剂在紫外/次氯酸(UV/Cl)体系中的光催氧化降解路径与产物毒性.结果表明,UV/Cl体系中的含氯自由基(RCS)与羟基自由基(·OH)易攻击阻燃剂分子结构上键能较低、Fukui指数较高的位点,促使C—Cl键、C—Br键、C—C键等因为受到攻击而断裂,进而降解阻燃剂.同时,利用ECOSAR模型评估发现降解产物的急性毒性LC_(50)-96 h均低于100 mg·L^(-1),佐证了UV/Cl体系对含卤阻燃剂降解的有效性,并降低其环境危害.因此,采用Gaussian计算、ECOSAR模型相结合的分析方法,能够更加便捷地预测阻燃剂降解路径与产物毒性特征,为深入揭示UV/Cl体系光催氧化降解含卤阻燃剂机理提供新思路.
