Perfect platin.m （Pt） n.n.cubes with high den.ity have been.syn.hesized by con.rolled reduction.of hexachloroplatin.c acid in.the presen.e of H2SO4 an. HCl, employin. a pair of low-resistivity fasten.d silicon.（FS） wafers at room temperature. The presen.e of the additive charges （in.uced by prior etchin. of the silicon.surface with HF to remove an. SiO2 layer） between.the in.erfaces of the FS surface results in.a high charge den.ity an. facilitates fast deposition.of Pt n.n.particles via electroless platin.. The charge den.ity, stirrin. time, an. homogen.ity of the aqueous solution.in.luen.ed the geometrical shapes of the Pt n.n.particles. The parameters were fin.ly tun.d in.order to con.rol the n.cleation.an. growth rates an. obtain.perfect Pt n.n.cubes. The perfect Pt n.n.cubes were sin.le crystallin. with exposed {100} facets. Per equivalen. Pt surface areas, the perfect Pt n.n.cubes showed en.an.ed catalytic activity relative to trun.ated Pt n.n.cubes or spherical Pt n.n.particles for the electrooxidation.of liquid feed fuels such as methan.l an. ethan.l. Moreover, there a stron. correlation.was observed between.the optical, electrical, thermal, magn.tic, an. catalytic properties of the perfect Pt n.n.cubes which should lead to a variety of techn.logical application. of these materials.

Stuck in.a rut： Poten.ial costs of san. roads to gopher tortoises Gopherus polyphemus

引用

作者： Lauren.n. GILSOn Archbold Biological station Lake Placid 123 Main Drive. Lake Placid. FL 33960. USA Departmen. of En.iron.en. an. Agriculture Curtin University Bentley WA 6845 Australia

Roads affect wildlife sign.fican.ly through direct mortality but also through behavioral chan.e. We explored the ef- fects of un.urfaced san. roads with a low traffic volume on.the travellin. behavior of gopher tortoises Gopherus polyphemus in.scrub habitat in.cen.ral Florida, as eviden.ed by the tracks left by tortoises on.san. roads. Tortoises （an. most other taxa leavin. tracks on.the roads） did n.t appear to make use of roads for travel but attempted to cross them, the success of which was in.lu- en.ed by the size of the in.ividual. Smaller an.mals （presumably youn.er tortoises） were more challen.ed than.larger an.mals by both san. road widths an. depths of vehicle ruts in.san. roads. San. roads may presen. both physical an. physiological challen.es to gopher tortoises, particularly to small on.s. This research provides further eviden.e that the n.gative in.luen.e of roads in.fragmen.in. the en.iron.en. is n.t limited to vehicle mortality [Curren. Zoology 61 （4）： 578-585, 2015].

In.ium tin.oxide （ITO） films were prepared by rf magn.tron.sputterin. un.er two con.ition.：（i） at substrate temperature Ts from room temperature （RT） to 350℃ （ii） with addition.l post-an.ealin. in.vacuum at 400℃ for 30 min.in.comparison.of their crystallin. structures, an. electrical-optical properties of the films deposited. From the experimen.al results, it is foun. that, un.er the first con.ition. the crystallin. structures an. the electrical-optical properties of the films are improved with the in.reasin. Ts. Un.er the other con.ition. i.e. with the addition.l post-an.ealin., the films exhibit higher degree of crystallin.ties an. better electrical-optical properties. Un.er the two deposition.con.ition., in.er-relation.between.electrical-optical properties an. the crystallin. structure is observed clearly. However, even.un.er the same an.ealin. con.ition. it is observed that improved properties of the films are differen., depen.in. on.their deposition.temperatures, which implies that an.in.tial stage of the ITO film before an.ealin. is an.importan. factor for the film＇s properties improved after an.ealin.. The resistivity of 2.33 × 10-4 Ω·cm can.be achieved at Ts of 350℃after an.ealin..

In.this work, n.n.structured silicon.dioxide films are deposited by closed-field un.alan.ed direct-curren. （DC） reactive magn.tron.sputterin.techn.que on.two sides of quartz cells con.ain.n. rhodamin.

The preparation.con.ition. are optimized to prepare highly pure SiO2 n.n.structures with a min.mum particle size of about 20n.. The effect of SiO2 films as extern.l cavity for the ran.om gain.medium is determin.d by the laser-in.uced fluorescen.e of this medium, an. an.in.rease of about 200% in.in.en.ity is observed after the deposition.of n.n.structured SiO2 thin.films on.two sides of the dye cell.

We in.estigated the fuel characteristics of five importan. bamboo species viz., Den.rocalamus strictus, D. bran.isii, D. stocksii, Bambusa bambos an. B. balcooa. The selected species cover more than.85% of the total growin. stock of bamboo in.In.ia. Basic den.ity varied from 0.48 to 0.78 ***-3 amon. the bamboo species studied. Ash con.en., volatile matter con.en. an. fixed carbon.con.en. ran.ed between.1.4%-3.0%, 77.2%-80.8% an. 17.6%-21.1%, respectively. Variation.in.calorific value （18.7-19.6 MJ-kg-l） was margin.l. Fuel value in.ex var- ied widely （586-2120） amon. bamboo species. The highest calorific value （19.6 ***＂l） an. fuel value in.ex （2120） were foun. in.B. bal- cooa. Ash elemen.al an.lysis revealed that silica an. potassium are the major ash formin. min.rals in.bamboo biomass. Silica con.en. ran.ed from 8.7% to 49.0%, while potassium ran.ed from 20.6% to 69.8%. We studied combustion.characteristics un.er oxidizin. atmosphere. Burn.n. profiles of the samples were derived by applyin. the derivative thermo- gravimetric techn.que which is discussed in.detail. The five bamboo species were differen. in.their combustion.behaviour, main.y due to differen.es in.physical an. chemical properties. We compare fuel prop- erties, ash elemen.al an.lysis an. combustion.characteristics of bamboo biomass with wood biomass of Eucalyptus hybrid （Eucalyptus tereticor- his × Eucalyptus camaldulen.is）.
