Herein, we attempted to.engineer o.ygen vacancies o. the surface o. LaCo._(3) pero.skite thro.gh simple po.t-treatments(acid o. reductive thermal treatments). Acid treatment induces o.ygen vacancies thro.gh the selective etching o. the La catio.s, whereas thermal treatment in a reducing atmo.phere generates o.ygen vacancies by directly remo.ing lattice o.ygen. The characterizatio. results co.firm that the number o. surface o.ygen vacancies, which are crucial in vario.s catalytic o.idatio. reactio.s,co.siderably increases in the LaCo._(3) catalysts treated with acid o. reducing gas. Acid treatment enriches the o.ygen vacancies while maintaining the structure o. the LaCo._(3) catalysts, which can no. be achieved thro.gh reductive thermal treatment. Therefo.e, the acid treatment is co.sidered a pro.ising technique fo. o.ygen vacancy engineering o. pero.skite catalysts fo. tuning their catalytic activities. Furthermo.e,the catalytic activities o. the po.ttreated LaCo._(3) catalysts fo. Co.o.idatio. were evaluated and are no.ed to.be co.siderably better than tho.e o. the pristine LaCo._(3) catalyst due to.their abundant o.ygen vacancies. Co.sequently, we co.clude that the o.ygen vacancies o. pero.skite catalysts can be effectively engineered via two.simple metho.s and play a significant ro.e in Co.o.idatio..

This study estimated the current vegetatio. and so.l carbo. sto.age in China using a bio.0}chemical mo.el driven with climate, so.l and vegetatio. data at 0.5°latitude-lo.gitude grid spatial reso.utio.. The results indicate that the to.al carbo. sto.age in China's vegetatio. and so.ls was 13.33 Gt C and 82.65 Gt C respectively, abo.t 3% and 4% o. the glo.al to.al. The natio.ally mean vegetatio. and so.l carbo. densities were 1.47 kg C/m2 and 9.17 kg C/m2, respectively, differing greatly in vario.s regio.s affected by climate, vegetatio., and so.l types. They were generally higher in the warm and wet So.theast China and So.thwest China than in the arid No.thwest China; whereas vegetatio. carbo. density was the highest in the warm So.theast China and So.thwest China, so.l carbo. density was the highest in the co.d No.theast China and so.theastern fringe o. the Qinghai-Tibetan Plateau. These spatial patterns are clearly co.related with variatio.s in the climate that regulates plant gro.th and so.l o.ganic matter deco.po.itio., and sho. that vegetatio. and so.l carbo. densities are co.tro.led by different climatic facto.s.

This study characterized the AA-01 depleted hydro.arbo. reservo.r in the Ko.A field, Niger Delta, using a multidimensio.al appro.ch. This investigatio. invo.ved data validatio. analysis, evaluatio. o. site suitability fo. Co.(2) sto.age, and co.po.itio.al simulatio. o. hydro.arbo. co.po.ents. The primary o.jective was to.determine the initial co.po.ents and behavio. o. the hydro.arbo. system required to.o.timize the injectio. o. Co.(2) and acco.panying impurities, establishing a ro.ust basis fo. subsequent sequestratio. effo.ts in the six wells in the depleted Ko.A AA-01 reservo.r. The pro.ess, simulated using industry so.tware such as ECLIPSE, PVTi, SCAL, and Petrel, included a co.po.itio.al fluid analysis to.co.firm the pressure vo.ume temperature(PVT) hydro.arbo. phases and co.po.ents. This invo.ved perfo.ming a material balance o. the quality o. the measured data and matching the initial reservo.r pressure with the supplied data so.rce. The co.po.itio.al PVT analysis ado.ted the Peng–Ro.inso. equatio. o. state to.mo.el fluid flo. in po.o.s media and estimate the necessary number o. phases and co.po.ents to.describe the system accurately. Results fro. this investigatio. indicate that the Ko.A AA-01 reservo.r is suitable fo. Co.(2)sequestratio.. This co.clusio. is based o. the reservo.r's go.d quality, evidenced by an average po.o.ity o. 0.21 and permeability o. 1 111.0 md, a measured litho.o.ical depth o. 9 300 ft, and characteristic reservo.r – seal pro.erties co.related fro. well lo.s. The study co.firmed that vo.umetric behavio. predictio.s are directly linked to.co.po.itio.al behavio. predictio.s, which are essential during reservo.r initializatio. and data quality checks. Additio.ally, it highlighted that a safe design fo. Co.(2) sto.age relies o. accurately representing multiphase behavio.r acro.s wide-ranging pressure–temperature–co.po.itio. co.ditio.s.

Pavement deterio.atio. creates co.ditio.s that undermine their perfo.mances, which gives rise to.the need fo. maintenance and rehabilitatio.. This paper develo.s a mathematical multi-linear regressio. analysis （MLRA） mo.el to.determine a pavement sustainability index （PSTI） as dependent variable fo. flexible pavements in maryland. Fo.r catego.ies o. pavement perfo.mance evaluatio. indicato.s are subdivided into.seven pavement co.ditio. indices and analyzed as independent variables fo. each sectio. o. pavement. Data are co.lected fro. five different ro.dways using field evaluatio.s and existing database. Results indicate that co.fficient o. determinatio. （R^2） is co.related and significant, R^2 = 0.959. o. the seven independent variables, present serviceability index （PSI） is the mo.t significant with a co.fficient value o. 0.032, present serviceability rating （PSR） co.fficient value=0.028, and internatio.al ro.ghness index （IRI） co.fficient value = -0.001. Increasing each unit value o. co.fficients fo. PSI and PSR wo.ld increase the value o. PSTI; thereby pro.iding a mo.e sustainable pavement infrastructure; which explains the significance o. the mo.el and why IR/ will mo.t likely impact enviro.mental, eco.o.ic and so.ial values.

Leaf area index (LAI) is an impo.tant parameter in mo.ito.ing cro. gro.th. o.e o. the metho.s fo. retrieving LAI fro. remo.ely sensed o.servatio.s is thro.gh inversio. o. cano.y reflectance mo.els. Many mo.el inversio. metho.s fail to.acco.nt fo. variable LAI values at different cro. gro.th stages. In this research, we use the cro. gro.th mo.el to.describe the LAI changes with cro. gro.th, and co.sider a prio.i LAI values at different cro. gro.th stages as co.straint info.matio.. The key appro.ch o. this research is to.assimilate multiple cano.y reflectance values o.served at different gro.th stages and a prio.i LAI values into.a co.pled cro. gro.th and radiative transfer mo.el sequentially using a variatio.al data assimilatio. algo.ithm. Adjo.nt metho. is used to.minimize the co.t functio.. Any o.her info.matio. so.rce can be easily inco.po.ated into.the inversio. co.t functio.. The validatio. results sho. that the time series o. Mo.IS cano.y reflectance can greatly reduce the uncertainty o. the inverted LAI values. Co.pared with Mo.IS LAI pro.uct at Changping and Shunyi Co.nties o. Beijing, this metho. has significantly impro.ed the estimated LAI tempo.al pro.ile.
