t.e PARASOL code and t.e simulat.on by using PARASOL are int.oduced briefly. t.e PARASOL code wit. part.cle-in-cell （PIC） met.od and binary collision model was developed in JAERI and JAEA. Simulat.ons using PARASOL code were carried out.in order t. invest.gat. t.e power and part.cle cont.ol wit. diveror syst.m in fusion react.rs. t.e one-dimensional （1D） version of PARASOL was adopt.d t. invest.gat. t.e Bohm crit.rion, t.e supersonic flow, t.e SOL heat.conduct.on, and so on. t.e heat.propagat.on due t. edge localized mode （ELM） was st.died wit. t.e 1D-dynamic PARASOL. t.e t.o-dimensional version of PARASOL for t.e whole t.kamak plasma including scrape-off-layer （SOL）-divert.r region was useful for simulat.ng t.e SOL flow pat.ern, t.e elect.ic field format.on et.. Based on PARASOL simulat.on result., improved physics modeling for t.e fluid simulat.on was built.up.

t.is review focuses on recent.development. in t.e fabricat.on of mult.ple emulsions in micro-scale syst.ms such as membranes, microchannel array, and microfluidic emulsificat.on devices. Membrane and microchannel emulsificat.on offer great.pot.nt.al t. manufact.re mult.ple emulsions wit. uniform drop sizes and high encapsulat.on efficiency of encapsulat.d act.ve mat.rials. Meanwhile, microfluidic devices enable an unprecedent.d level of cont.ol over t.e number, size, and t.pe of int.rnal droplet. at.each hierarchical level but.suffer from low product.on scale. Microfluidic met.ods can be used t. generat. high-order mult.ple emulsions （t.iple, quadruple, and quint.ple）, non-spherical （discoidal and rod-like） drops, and asymmet.ic drops such as Janus and t.rnary drops wit. t.o or t.ree dist.nct.surface regions. Mult.ple emulsion droplet. generat.d in microfabricat.d devices can be used as t.mplat.s for vesicles like polymersomes, liposomes, and colloidosomes wit. mult.ple inner compart.ent. for simult.neous encaosulat.on and release of incomoat.ble act.ve mat.rials or react.nt..

In Houst.n, a combinat.on of urban emissions from a cit. of 4 million people, coupled wit. emissions from ext.nsive pet.oleum refining and chemical manufact.ring, leads t. condit.ons for phot.chemist.y t.at.are unique in t.e Unit.d St.t.s, and hist.rically, t.e cit. had experienced some of t.e highest.ozone concent.at.ons recorded in t.e Unit.d St.t.s. Large air qualit. field st.dies （t.e t.xas Air Qualit. St.dies or t.xAQS I and II） were conduct.d t. det.rmine root.causes of t.e high ozone concent.at.ons. Hundreds of air qualit. invest.gat.rs, from around t.e world, deployed inst.ument. on aircraft. on ships, and at.fixed ground sit.s t. make ext.nsive air qualit. measurement.; det.iled phot.chemical modeling was used t. int.rpret.and assess t.e implicat.ons of t.e measurement.. t.e t.xas Air Qualit. St.dies revealed t.at.bot. cont.nuous and episodic emissions of light.alkenes, which came t. be called highly react.ve volat.le organic compounds, played a crit.cal role in t.e format.on of ozone and ot.er phot.chemical oxidant. in t.e region. Under- st.nding and quant.fying t.e role of t.ese emissions in regional air qualit. required innovat.ons in charact.rizing emissions and in phot.chemical modeling. Reducing emissions required innovat.ve policy approaches. t.ese coupled scient.fic and policy innovat.ons are described, and t.e result. subst.nt.ally cleaner air for Houst.n, is document.d. t.e lessons learned from t.e Houst.n air qualit. experience are relevant.t. cit.es wit. similar populat.on and indust.ial profiles around t.e world.
