A cleanser based on sodium laureth carboxylate and alkyl carboxylates washes facial sebum well but does not induce dry skin.

Background: Because excess sebum and/or metabolites of sebum induce skin problems, cleansers that can remove those kinds of sebum are sought after. However, many people, especially who have little facial sebum, are afraid to wash off sebum well because that may induce dry skin. This concern may be caused by the result that cleansers with a high cleansing ability tend to decrease not only facial sebum but also natural moisturizing factors and intercellular lipids that are essential for cutaneous function.

Highly temperature-sensitive liposomes based on a thermosensitive block copolymer for tumor-specific chemotherapy.

Recently, we showed that incorporation of poly[2-(2-ethoxy)ethoxyethyl vinyl ether (EOEOVE)], which exhibits a lower critical solution temperature around 40 degrees C, provides temperature-sensitive properties to stable liposomes. In this study, we applied this thermosensitive polymer for preparation of temperature-sensitive liposomes for tumor-specific chemotherapy with doxorubicin (DOX). We prepared liposomes consisting of PEG-lipid, egg yolk phosphatidylcholine, cholesterol and copoly(EOEOVE-block-octadecyl vinyl ether), which was synthesized as poly(EOEOVE) having anchors for fixation onto liposome membrane.

Low-temperature synthesis of anatase-brookite composite nanocrystals: the junction effect on photocatalytic activity.

Anatase-brookite composite nanocrystals have successfully been synthesized at 50 degrees C using a simple liquid-phase process. The photocatalytic activity of the sample for the gas-phase oxidation of CH3CHO is 5.4 times greater than that of a single-phase anatase sample with comparable crystallite size and surface area.

Photocatalytic activity of rutile-anatase coupled TiO2 particles prepared by a dissolution-reprecipitation method.

Rutile TiO(2) particles were partly dissolved into aqueous solutions of H(2)SO(4), and the Ti(4+) ions were reprecipitated by adding NH(3) aq. Rutile-anatase coupled TiO(2) particles were prepared by heating the solid recovered after centrifugation of the suspension. The content of anatase (c(A), wt%) could be controlled arbitrarily by changing the dissolved amount of rutile.
