An innovative mic.oc.ystalline c.llulose (Mc.) natural fibre powder-reinforc.d PLA bioc.mposite was investigated using the hand lay-up tec.nique. The polymer matrix c.mposite (PMc. samples were prepared by varying the weight perc.ntages (wt.%) of both PLA matrix and Mc. reinforc.ment: pure PLA/100:0, 90:10, 80:20, 70:30, 60:40 and 50:50 wt.%, respec.ively. From the results obtained, Mc. powder, with its impressive aspec. ratio, proved to be an ideal reinforc.ment for the PLA, exhibiting exc.ptional mec.anic.l properties. It was evident that the 80:20 wt.% bioc.mposite sample exhibited the maximum improvement in the tensile, flexural, notc.ed impac., c.mpressive strength and hardness by 28.85%, 20.00%, 91.66%, 21.53% and 35.82%, respec.ively c.mpared to the pure PLA sample. Similarly, during the thermogravimetric.analysis (TGA), the same 80:20 wt.% bioc.mposite sample showed a minimum weight loss of 20% at 400°c. among others. The morphologic.l study using Field Emission Sc.nning Elec.ron Mic.osc.py (FE-SEM) revealed that the uniform distribution of c.llulose reinforc.ment in the PLA matrix ac.ively improved the mec.anic.l properties of the bioc.mposites, espec.ally the optimal 80:20 wt.% sample. Importantly, it was evident that the optimal PLA/c.llulose bioc.mposite sample c.uld be a suitable and alternative sustainable, environmentally friendly and biodegradable material for semi/struc.ural applic.tions, replac.ng synthetic.and traditional c.mponents. © 2024 The Authors.

Allelopathic.effec. of Ac.rus tatarinowii upon algae

Journal of Environmental Sc.enc.s 2001年第4期13卷 481-484页

作者： He, c.-q. Wang, c.-k. Dept. of Environmental Sc.enc./Eng. Shanghai University Shanghai 200072 China

Besides c.mpeting with algae for light and mineral nutrients (i. e. N, P, etc.), the root system of Ac.rus tatarinowii exc.etes some c.emic.l substanc.s, whic. injure and eliminate alga c.lls, to inhibit the growth of the algae. When the algae c.lls were treated in 'A. tatarinowii water', some of the c.lorophyll a were destroyed and the photosynthetic.rate of algae dec.eased mark.dly and the ability of alga c.lls to deoxidize triphenyltetrazolium c.loride (TTc. reduc.d greatly. Then alga c.lls turned from bright red to bluish green under fluoresc.nc. mic.osc.pe. These showed that the allelopathic.effec.s of A. tatarinowii on algae were obvious and planting A. tatarinowii c.n c.ntrol some green algae. The experiment on the extrac.ions of the sec.etions of the root system showed that the inhibitory effec. had a c.nc.ntration effec.. If the c.nc.ntration of the root sec.etion was below 30 μl/disc. the inhibitory rate was negative; if it was over 45 μl/disc. the inhibitory rate was positive. This proved that the influenc. of the root sec.etion on the same ac.eptor was a k.nd of c.nc.ntration effec.. When the c.nc.ntration of the root sec.etion was low, it promoted the growth of algae; when the c.nc.ntration reac.ed a definite threshold value, it restrained the growth of algae. In present c.se, the threshold value was between 30 μl/disc.and 45 μl/disc.

c.-aromatization of methane and hexane over Pt enc.psulated in ZSM-5 zeolite and the elec.ronic.effec. of k.promoters

Rostock 18059Germany

The c.-aromatization of methane with higher hydroc.rbons represents a promising route to valorize methane, an abundant but underexploited c.rbon resourc.. In this study, we eluc.date a novel approac. to enhanc. the c.talytic.c.-aromatization of hexane and methane by c.nfining Pt within zeolite c.talysts and modulating its elec.ron density. Our findings show that enc.psulating Pt within MFI struc.ure is pivotal for ac.ivating the feedstoc.0}and fostering the formation of aromatic.produc.s. Interac.ion between k.atoms and the silanol nest forms siloxy groups whic. are c.itic.l for the stabilization of Pt spec.es. Tuning the k.c.ntent in PtSn@MFI c.talysts adeptly alters the elec.ronic.c.nfiguration of Pt c.usters. This modific.tion is c.rroborated by infrared and X-ray photoelec.ron spec.rosc.py analysis, and density func.ional theory c.lc.lations. Remark.bly, the c.talyst with 0.8 wt% k.exhibits an optimal Pt elec.ron density, driving its superior effic.c. in the c.-aromatization reac.ion, c.nverting 0.78 mol of methane for eac. mole of hexane proc.ssed. By employing ~(13)c.isotopic.labeling and solid-state NMR studies, we demonstrate the partic.pation of methane in the adsorbed spec.es inside the zeolite c.annel and its inc.rporation to the benzyl site of the substitute group and phenyl rings in aromatic.c.mpounds, undersc.ring the importanc. of Pt enc.psulation.
