Abstract: Disclosed herein are modified chromium-dpoed zinc gallate (ZGC) nanocubes, which are characterized in respectively having a concave surface that is modified with (3-aminopropyl)triethoxysilane (APTES). The modified ZGC nanocubes produce long lasting luminescence (LLL) that lasts for at least 1.5 hours under X-ray or UV excitation. Also disclosed herein are methods for the preparation of the modified ZGC nanocubes; and methods for imaging an area of interest (e.g., cancer) in a live subject using the modified ZGC nanocubes as an imaging agent.
Abstract: The invention relates to a process for preparing an ?-methylene ketone comprising the step of reacting a ketone with formaldehyde in the presence of a catalyst which is an organic compound comprising at least one acid function or the corresponding salt, ester or amide thereof and at least one amine function or the corresponding ammonium salt, or a zwitterion thereof.
Abstract: Described is a process of making pseudoionone and hydroxy pseudoionone comprising the steps of (i) preparing a first aqueous mixture comprising first concentrations of acetone, citral and hydroxide, (ii) producing a second aqueous mixture by allowing to react for a reaction time the components of the first aqueous mixture and (iii) producing a third aqueous mixture by adding to the second aqueous mixture a second amount of hydroxide so that an additional amount of pseudoionone is formed in the third aqueous mixture. The invention further suggests an apparatus for making pseudoionone and hydroxy pseudoionone as well as to a respective process and use of said apparatus in making pseudoionone and hydroxy pseudoionone.

Abstract: The present invention relates to a method for producing a 3-methylcycloalkenone compound and a method for producing muscone. In the presence of a zirconium oxide catalyst, a diketone represented by the following general formula (1): wherein in formula (1), n represents 8, 9, 10, 11 or 12, is subjected to a vapor-phase intramolecular condensation reaction, whereby a 3-methylcycloalkenone compound can be produced with high reaction efficiency. When a 3-methylcyclopentadecenone compound produced by this method is hydrogenated in a known manner, muscone can be produced efficiently.
