Abstract

In
this paper, Reversed-Flow Gas Chromatography (RF-GC) is utilized to
investigate the evaporation of low molecular weight alcohol. Evaporation
rates as well as the diffusion rates of methanol are determined with a
surfactant monolayer on the surface of the liquid; while nitrogen acts
as carrier gas, at 313 K. The precision (>99.9) and accuracy of this
investigation demonstrates the potential of current methodologies for
environmental impact studies; this is further verified when the results
are compared with the available literature. The varying evaporation
rates of methanol in the presence of varying amounts of Triton X-100
reflects that application of surfactants do damper the evaporation rates
of liquid pollutants; without interference with the formers diffusion
coefficients. High amounts of Triton X-100 are required for retardation
of evaporation rates, suggesting the formation of a densely packed
surface monolayer or the formation of an insoluble monolayer.

Beware of the BOGUS / FAKE JOURNAL!!! (HIJACKED JOURNALS)

Currently, I received an invitation to submit my manuscript to Bothalia Journal through my email:

Figure 1: Invitation for manuscript submission through email


The "real" bothalia journal an ISI indexed journal and listed in SCIENCE CITATION INDEX EXPANDED:

Figure 2: The proof of Bothalia is an ISI-WoS journal


The journal also possess an Impact Factor (IF)  of 0.846 (JCR 2012) which is ranked in Quartile 3 in PLANT SCIENCE category:

Figure 3: Bothalia's Impact Factor

But there are two links to the journal website when I tried to search with google:

1. The original journal website.

Figure 4: "Original" Bothalia journal website

2. The bogus/fake journal website.

Figure 5: "Fake" Bothalia journal website

The fake/bogus journal even listed in the first place through google search results!

The Original Bothalia Journal has also posted an alert (cf. black circle in the figure below) for this fake Bothalia Journal.:


Figure 6: The alert for the "fake/bogus" journal in the real Bothalia journal's website

P/S: Complete list of the hijacked journals can be found in this website.

-Usually, the fake/bogus journal usually requires you to pay some amount of money to a bank account in Africa, Pakistan, etc.

-The fake journal will have a fast peer reviewed processes - today submitted, tomorrow accepted!

-The Original Journal Publisher do not simply invite to submit your manuscript through e-mail.

-The submitted articles to the fake/bogus journal will not count as an ISI publication since it will not listed in Web of Science (WoS)

BEWARE OF FAKE/JOURNAL AND SAVE YOUR MONEY V^^V

How to check whether the Journal is indexed in ISI-WoS (Web of Science)?

Introduction to Web Of Science

Web of Science, (WoS) (previously known as ISI-Web of Knowledge [ISI-WoK]) is an online subscription based scientific service maintained by Thomson Reuters. Web of Science gives comprehensive citation search experience. Web of Science (WoS) (Figure 1) gives access to huge range of databases that reference cross disciplinary research, which allows for in-depth exploration of specified sub field within an academic or scientific discipline [1].





Eugene Garfield (Figure 2) is the founder of The Institute of Scientific Information (ISI) known as "father of citation indexing of academic literature" [2], who launched Science Citation Index (SCI) which in turn becomes Web of Science (WoS) [3]. 




Figure 2 : Eugene Garfield


However, in 1992, Institute for Scientific Information (ISI) was acquired by Thomson Reuters and is now called Thomson Reuters-Web of Science. There is no difference between ISI-WoK and Thomson Reuters-Wos in coverage [4]. 

Figure 3 illustrates the diversity of database for academic literature searching in the internet. JSTOR, SCOPUS, ULRICH, Google Scholar, ERIC, Index Coppernicus, DOAJ, EBSCO, ProQuest  are a few example of academic searching databases that available in the internet. These databases (blue rain drops) are not covered by Thomson Reuters-WoS. Only the databases under the umbrella (yellow boxes, underneath the umbrella on the right and the left sides) are covered by Thomson Reuters-WoS and search-able within the WoS.




Figure 3 : Illustration of diversity of academic searching databases in the internet

The following databases: FSTA - the food science resource, INSPEC, Korean Citation Index, MEDLINE, Russian Citation Index and SciELO Citation Index are not Thomson Reuters databases [5]. They are owned by other organizations. However, Thomson Reuters is getting the data from respective organizations and indexing it in WoS [5]. Those databases are called Hosted databases (collaboration between Thomson Reuters and other organizations, for example, Thomson Reuters and the Chinese Academy of Sciences host the Chinese Citation Index Data in Web of Science).

Up-to-date (as December 2015), Thomson Reuters covers estimated 33,000 journal titles in WoS [4]. Out of 33,000 journals listed in Thomson Reuters-Web Of Science formerly known as ISI-Web Of Knowledge (WOK), only 19, 000 journals listed as Thomson Reuters-WoS (Web of Science) Core Collection (Figure 3) [4].

The journals listed in databases on the left part (under the yellow umbrella) are covered in Web of Science Core Collection (WoS CC). Journals indexed in Science Citation Index Expanded(SCI-E) and Sosial Science Citation Index (SSCI) are eligible for Impact Factor(IF) calculation in Journal Citation Report (JCR) [4] [refer figure 3 {red arrow : only journals indexed in SCI-E and SSCI will appear in JCR with IF}]

Journal indexed in Arts & Humanities Citation Index (AHCI) will not appear in JCR because in this area, a large amount of work is done in books rather than in journals [4]. Conference Proceedings Citation Index (CPCI), Book Citation Index, Current Chemical Reaction and Index Chemicus not appear in JCR and thus with no IF


Universiti Malaya's policies on publication in Web of Science

Universiti Malaya (UM) has subscribed only for WoS CC, Derwent Innovation Index, Korean Citation Index and SciELO Citation Index (Figure 4). As UM has not subscribed for other databases such as Biological Abstract, BIOSIS, CABI etc., UM's post grads and staffs will not be able to see those databases in "All Databases" as in Figure 4.




Figure 4 : Databases in WoS subscribed by UM


UM only recognizes Original Research Articles and Review Papers (letters, commentaries, short communications, others ARE NOT INCLUDE) indexed in SCI-E, SSCI and AHCI [6] as ISI-WoS publication for graduation purposes [7]. See Figure 5 for example of publication requirement for UM's postgraduate student. 




Figure 5 : Example of publication requirement for Master's graduation in UM (2012)


The conference proceedings are not recognized as the ISI publication in Universiti Malaya even though the proceedings are listed in WoS CC [5]. New publication requirement for Universiti Malaya's postgraduate candidates by research (as senate approval on 28.05.2015) can be found here.



TO CHECK WHETHER THE JOURNAL IS ISI-INDEXED WITH IMPACT FACTOR (IF) AND NOT FAKE A JOURNAL (see example here) :



1. Check for the journal title in Master Journal List (MJL)

MJL will displays only journals that accepted for coverage in Thomson Reuters databases [5] (Figure 6). Derwent Innovation Index covers patent, so it was not included in MJL.




Figure 6 : Master Journal List


The reason Thomson Reuters is displaying "(Web of Science)" as in Figure 7 (red square) is because when a journal is accepted for coverage in the following citation indexes: SCI-E, SSCI, AHCI, Emerging Sources Citation Index (ESCI), the publishers (e.g. Elsevier) consider them as WoS indexed journal [5]. 




Figure 7 : Journal Lists for Searchable Databases in MJL


Most of the institution or organization (including UM) a journal indexed in SCI-E, SSCI, AHCI or ESCI is good, when it is indexed in these databases [5]. Similarly, the authors who are submitting their article to a journal also wish to have their article published in the journal covered by these databases [5].

You can check which index category that the journal falls within WoS by browsing MJL. Please ENSURE that the journal is listed either in SCI-ESSCI , AHCI or ESCI.

BE AWARE of JOURNAL COVERAGE CHANGES in SCI-E and SSCI as some of the journals will be dropped from MJL eventhough the journal carried IF in JCR. For example, Problems of Atomic Science Science and Technology was dropped from MJL (see notice HERE) (Figure 8) but the still appear in JCR Edition 2014 with IF of 0.136 (Q4 in four categories: 1. NUCLEAR SCIENCE & TECHNOLOGY, 2. PHYSICS, FLUIDS & PLASMA, 3. PHYSICS, NUCLEAR, 4. PHYSICS, PARTICLES &FIELDS) (Figure 9). 







Figure 9 : IF for Problems of Atomic Science Science and Technology was 0.136 (JCR Edition 2014)


Unfortunately, IF still being displayed in journal's homepage (Figure 10) which can cause confusion for the authors who want to submit their manuscript to this journal! 



Figure 10 : IF still being displayed in Problems of Atomic Science Science and Technology's hompage.


The newly added journal into SCI-E or SSCI will not carry IF as the journal will only received its first IF after THREE YEARS! [8]. For example, The Malaysian Journal of Pathology is newly added to MJL and indexed in SCI-E, see notice HERE (or please refer to Figure 11).



Figure 11 : The notice in SCI-E journal coverage changes on addition of The Malaysian Journal of Pathology 


Other example, LGBT Health is also newly added to MJL and indexed in SSCI, see notice HERE (or please refer to Figure 12).

2. Check the the article from that particular journal is listed in WoS. 

The link to WoS database only can be accessed if your university subscribe to Web Of Science  (log in to your library portal website, i.e. EZproxy: Universiti Malaya, Universiti Sains Malaysia, Universiti Kebangsaan Malaysia, Universiti Putra Malaysia, Universiti Teknologi Malaysia). Example of EZproxy URL is shown in red box of Figure 13:




Figure 13 : Example of URL EZproxy 


Ensure that you choose Web of ScienceTM Core Collection tab (by choosing this tab you will exclude the conference proceedings in your searching) (Figure 14). 




Figure 14 : Choosing Web of Science Core Collection


Next, scroll down the page until you find "MORE SETTINGS" tab. Unchecked the last three boxes (Figure 15) 



Figure 15 : Settings option in Web Of Science Core Collection



3. Check for Impact Factor (IF) of the journal (if applicable) 

The link to JCR can be accessed via your respective university databases (please log in to your EZproxy account - depends on university subscription : Universiti MalayaUniversiti Sains MalaysiaUniversiti Kebangsaan MalaysiaUniversiti Putra MalaysiaUniversiti Teknologi Malaysia): Journal Citation Report (JCR)

BEWARE of notices (Figure 16) in Journal Citation Report (JCR) for title suppression (Figure 17) and journal coverage changes since some journals are newly added or dropped from Web Of Science.

4. Check for genuinity of the journal

Ensure that the journal is NOT A HIJACKED JOURNAL by browsing this website

Also be AWARE of possible, potential, or probable scholarly open-access journals and publishers. For the list of BLACKLISTED PUBLISHERS BY MINISTRY OF HIGHER EDUCATION OF MALAYSIA see here.



If you are still have doubt on the status of a journal, do not hesitate to email Thomson Reuters representative. They are willing to help you.




SO, "THE MAIN KEY IS CHECK! CHECK! CHECK!" [6]

New Article Acceptance: Transport phenomena and evaporation on interface of gas-liquid by Reversed-Flow Gas Chromatography

I have received notice that my review article titled Transport phenomena and evaporation on interface of gas-liquid by Reversed-Flow Gas Chromatography will be published by Asian Journal of Chemistry. The web page for the journal follows: http://www.asianjournalofchemistry.co.in/Home.aspx

No date as to when the article will be published but it should be this fall. Listed below is the abstract for the journal article to give those interested an indication of what the article is about.

Gas-liquid interface plays a major interest in environmental studies especially when the researchers are interested to study the diffusion coefficients and rate coefficients of the liquid under studies into the chosen carrier gas. The study of the gas-liquid interface by Reversed-Flow Gas Chromatography (RF-GC) is based on Ficks first law in one dimensional and Henry’s law. Based on the two laws, an extensive works have been done previously by using Reversed-Flow Gas Chromatography (RF-GC) methodologies to determine physiochemical properties on the gas-liquid interface. The setup for this method is just by modifying the commercial gas chromatography by including diffusion column which orientated right angle to the sampling which carried the carried gas. The bottom part consists of the glass bottle which holds the liquid under studies. The usage of six-port or four-port valves play a major role in this methodologies since the equipment allows the carrier gas to reverse and retain its original flow from time to time and thus creating a ‘sample peak’ which sits on the continuous signal versus time chromatogram. The diffusion column which contains stagnant carrier gas accounts for the stationary phase and thus contributes to the physiochemicals phenomena of the interface. This methodology can be considered as fast sampling procedure as compared to the others in term of determining rate coefficients and diffusion coefficients of liquid sample into the carrier gas. The methods not only important in environmental investigation but also can be applied in the area of material science, food chemistry, nanotechnology, biological science and chemical technology.


This is my first ISI published paper and Alhamdulillah I have already fulfill the requirement for master degree graduation in University of Malaya.

For 2012, the journal ASIAN JOURNAL OF CHEMISTRY has an Impact Factor of 0.253 as shown in the figure below:

Experimental Setup for Reversed-Flow Gas Chromatography (RF-GC) system

The experimental arrangement consists of a small modification of a commercial gas chromatograph (Figure 1), so that it includes a six-port gas-sampling valve, and a simple cell placed inside the chromatographic oven. This cell suppresses the effects of the carrier gas flow on the physicochemical phenomena-taking place in the stationary phase.

Figure 1:       Shimadzu GC-14B
The apparatus used is a conventional gas chromatograph (Shimadzu GC-14B) with a flame ionization detector contained in its oven (Figure 2) with two sections of lengths l’ and l of a stainless-steel chromatographic column containing no chromatographic material. The empty stainless steel is a ¼ inch chromatographic tube with 4 mm internal diameter and length, L= 28.5 cm and l=l’=57 cm. They are connected at the junction x=l’ by a ¼ inch Swagelok tee union. Another sample ¼ inch union is used to connect a short tube (2 cm) containing 4 ml of liquid at the end of diffusion column L.


Figure 2:       Instrumentation of the reversed flow gas chromatography technique for the simultaneous measurement of the diffusion coefficients and rate transfer coefficients of the evaporating liquids.
A stainless-steel diffusion column, consisted of the section z, was connected perpendicularly at its upper end to the middle of the column l’+l (57 cm+57 cm). The reactant (AR Grade) was injected at a middle point of the column as the stationary phase, and the direction of carrier gas flow was reversed from time to time instead of stopping it. This created extra chromatographic peaks ‘sited’ on the continuous signal. At the end of sectiozn is located a container, in which the liquid was contained. The end D1 of the sampling column l’+l was connected, via a six-port valve, to the carrier gas (nitrogen) supply, while the other end D2 was connected to the flame ionization detection (FID) system. After waiting for the monotonously rising concentration– time curve to appear in the detector signal, we started the chromatographic sampling procedure by reversing the direction of the carrier gas flow for 6 s, which is a shorter time period than the gas hold-up time in both column sections l and l’. When the gas flow was restored to its original direction, sample peaks were recorded. The pressure drop along l+l’ was negligible and the pressure inside the whole cell was 1 atm. The carrier gas flow-rate was kept constant (1.0 cm3 s -1).
