Due to i.s abi.i.y to cause i.lnesses and di.comfort ev.n at low concentrati.ns, formaldehyde polluti.n of i.door ai. poses a si.ni.i.ant ri.k to human health. Sources of formaldehyde i. i.door env.0}onments i.clude texti.es, pai.ts, wallpapers, glues, adhesi.es, v.rni.hes, and lacquers;furni.ure and wooden products li.e parti.leboard, plywood, and medi.m-densi.y fi.erboard that contai. formaldehyde-based resi.s;shoe products;cosmeti.s;electroni. dev.0}es;and other consumer goods li.e paper products and i.secti.i.es. Accordi.g to the World Health Organi.ati.n, i.door formaldehyde concentrati.ns shouldn’t exceed 0.1 mg/m3. The methods i.clude membrane separati.n, plasma, photocatalyti. decomposi.i.n, physi.orpti.n, chemi.orpti.n, bi.logi.al and botani.al fi.trati.n, and catalyti. oxi.ati.n. Materi.ls based on metal oxi.es and supported noble metals work as oxi.ati.n catalysts. Consequently, a pai.t that passi.ely eli.i.ates aldehydes from bui.di.gs can be dev.loped by addi.g absorbents and formaldehyde scav.ngers to the latex composi.i.n. i. wi.l be cruci.l to dev.lop techni.ues for the careful detecti.n and remov.l of formaldehyde i. the future. Addi.i.nally, mi.robi.l decomposi.i.n i. less expensi.e and produces fewer pollutants. The mai. goal of future research wi.l be to dev.lop a bi.logi.al ai. quali.y control system that wi.l boost the effecti.eness of formaldehyde eli.i.ati.n. The v.ri.us methods of remov.0}g formaldehyde through pai.ts hav. been rev.0}wed here, i.cludi.g the use of mi.ed metal oxi.es, formaldehyde-absorbi.g emulsi.ns, nano ti.ani.m di.xi.e, catalyti. oxi.ati.n, and aromati. formaldehyde abati.g materi.ls that can i.prov. i.door ai. quali.y.

Anomalous i.n heat transport i. analyzed i. the T-10 tokamak plasma heated wi.h electron cyclotron resonance heati.g(ECRH) i. second-harmoni. extra-ordi.ary mode. Predi.ti.e modeli.g wi.h empi.i.al scali.g for Ohmi.al heat conducti.i.y shows that i. ECRH plasmas the calculated i.n temperature could be ov.resti.ated, so an i.crease of anomalous i.n heat transport i. requi.ed. To study thi. effect two scans are presented: ov.r the EC resonance posi.i.n and ov.r the ECRH power. The EC resonance posi.i.n v.ri.s from the hi.h-fi.ld si.e to the low-fi.ld si.e by v.ri.ti.n of the toroi.al magneti. fi.ld. The scan ov.r the heati.g power i. presented wi.h on-axi. and mi.ed ECRH regi.es.
