Various coatings have been developed and explored to protect bronze surfaces against the uncontrolled formation of different corrosion products when exposed to outdoor environments.
In this research, the surfaces of artificially-formed oxidized bronze patinas (OB), consisting of Cu2O, were covere ...

Baker ter bakrove zlitine se na vlažnem zraku pasivirajo, prihaja do nastanka t. i. patin. Najprej se tvori rdečkast kuprit, ki se nato počasi spreminja v črn tenorit. Če pa so v atmosferi agresivne zvrsti, lahko nastali kisli dež vpliva na tvorbo različnih korozijskih produktov. Patina, ki se tvori ...

When bronze or artificially patinated bronze is exposed to an outdoor environment that contains aggressive ions such as sulphates, nitrates, and carbonates, the surface of the bronze changes its appearance due to the formation of corrosion products on the surface. Research is being conducted on vers ...

Mezoporozni delci so porozni materiali, ki vsebujejo kanale por premera med 2 nm in
50 nm. Zaradi visoke specifične površine, ozke porazdelitve velikosti por in možnosti modifikacije porozne matrice s kovalentno vezavo različnih funkcionalnih skupin (t.i. reakcijo funkcionalizacije) in/ali adsorpc ...

Bronze surfaces, whether bare or patinated, tend to change when exposed to an outdoor atmosphere. Art made of bronze which is exposed to the outdoors is usually artificially patinated. This patina changes when exposed to rain, especially in polluted rain, where sulphuric, nitric or carbonic acids ar ...

In this study, several variations of Ti–6Al–4V β-grains and α′-martensites were observed while changing the combinations of laser parameters and keeping the energy density (ED) constant in the laser powder bed fusion (LPBF) process. Several combinations of laser power, scanning speed, and hatch spac ...

A model organic pigment (diketopyrrolopyrrole) is encapsulated by a silica coating in order to improve its photochemical stability. Unlike in previous works where single-layer silica coatings were used for similar purposes, we here propose creation of a multi-layer silica shell synthesized via in-si ...

Mezoporozno strukturirani delci SiO2 so silikatni materiali z dobro definiranimi kanali por s premerom med 2 nm in 50 nm, ozko porazdelitvijo velikosti por in visoko specifično površino (nad 1000 m2 g-1). Površina v porah delcev predstavlja t. i. notranjo površino, površina na zunanji strani delcev ...

We present a novel % cutoff concept of colorimetric indication of relative humidity based on dye dissolution in condensed water in capillaries of selectively functionalized mesoporours host SiO2 material. Consistently high levels of indoor air humidity induces mold and algae growth which represent a ...
