1. a. Judul Artikel: Photocatalytic self-cleaning properties of

cellulosic fibers modified by nano-sized zinc oxide

b. Abstrak: Nano-sized zinc oxide was synthesized and deposited

onto cellulosic fibers using the solgel process at ambienttemperature. The prepared materials were characterized using

several techniques including scanning electron microscopy,

transmission electron microscopy, diffuse reflectance

spectroscopy, X-ray diffraction and thermogravimetric analysis.

X-ray diffraction studies of the ZnO-coated fiber indicate

formation of the hexagonal crystal phase which was satisfactory

crystallized on the fiber surface. The electron micrographs show

formation of zinc oxide nanoparticles within 1015 nm in size

which have been homogeneously dispersed on the fiber surface.

The prepared materials show significant photocatalytic self-

cleaning activity, which was monitored by diffuse reflectance

spectroscopy. The photoactivity was studied upon measuring the

photodegradation of methylene blue and eosin yellowish under

UVVis irradiation. The photocatalytic activity of the treated

fabrics was fully maintained performing several cycles of

photodegradation.

(DPPH) was measured and these compounds were found to

scavenge DPPH free radical efficiently. Five selected

compounds were able to protect curcumin from the attack ofsulfur free radical generated by radiolysis of glutathione

(GSH). The newly synthesized compounds exhibitedprofoundantioxidantactivities. Five of them rendered

comparatively high antioxidant capacity.

3. a. Nama Jurnal: Carbohidrate research

Scope: which includes all aspects of carbohydrate chemistry and

biochemistry. Articles published in the journal cover sugars and

their derivatives (also cyclitols, and model compounds for

carbohydrate reactions), oligo- and polysaccharides, nucleosides,

nucleotides, and glycoconjugates.

These systems are considered from the viewpoints of:

chemical synthesis;

the study of structures and stereochemistry;

reactions and their mechanisms;

isolation of natural products;

physicochemical studies;

macromolecular dynamics;

analytical chemistry; biochemistry (biosynthesis,

metabolism, degradation, structural and functional

biochemistry, enzyme mechanisms, glycosidases and glycosyl

transferases, etc.);

action of enzymes;

immunochemistry;

technological aspects;

glycomics;

glycoinformatics;

glycobiology

The journal includes normal length research papers, mini reviews,

notes, rapid communications and book reviews together with

notices of meetings concerned with carbohydrates.

b. Nama Jurnal: chemical reviews

Scope: Chemical Reviews is one of the most highly regardedand highest-ranked journals covering the general topic of

chemistry.

The mission of Chemical Reviews is to provide comprehensive,authoritative, critical, and readable reviews of important recent

research in organic, inorganic, physical, analytical, theoretical, and

biological chemistry.

In addition to the general reviews, the journal has published since

1985 periodic thematic issues focusing on a single theme ordirection of emerging research

c. Nama Jurnal: Green Chemistry

Scope:based on, but not limited to, the definition proposed byAnastas and Warner (Green Chemistry: Theory and Practice, P. T.Anastas and J. C. Warner, Oxford University Press, Oxford,

1998): Green chemistry is the utilisation of a set of principles that

reduces or eliminates the use or generation of hazardous

substances in the design, manufacture and application of chemical

products.

d. Nama Jurnal:Journal of Herbs, Spices and Medicinal Plants


5/12

Scope: TheJournal of Herbs, Spices & Medicinal Plants is an

essential reference filled with recent research and other valuable

information associated with herbs, spices, and medicinal

plants. TheJournalserves as a focus point through which

investigators and others may publish material of importance to the

production, marketing, and utilization of these plants and

associated extracts. The journal covers the following topics:

growth, development, horticulture, ecology, physiology, genetic,

chemistry, and economics.

Original articles, review articles, and book reviews provide

information of interest to an international audience of researchers,
