Unveiling the ‘Mask of Motherhood’: Daughter Decodes Mother’s Postpartum Struggle in Maya Shanbhag Lang’s Memoir What We Carry (2020)
Authors:   School of Humanities, Social Sciences and Management, Indian Institute of Technology Bhubaneswar, Mukherjee Sumana , Satapathy Amrita
Published: January 2025

Mother and motherhood have always been associated with an unachievable archetype- strong, competent, effortless, untroubled, and invincible. Transmitted from mothers to daughters, this image has symbolized the trope of the ideal mother and motherhood for ages. The incessant expectations from Indian mothers as idols of altruïsm and boundless affection have generated a fabricated idea of motherhood. This situation often places new mothers in a bind, the starting point of which begins with not recognizing their postpartum struggle. Further, it imposes a burden on such mothers by thrusting them into a state of mental anxiety and depression. Maya Shanbhag Lang’s (2020) memoir What We Carry deals with the unvoiced and yet crucial topic of postpartum depression. While battling her postpartum depression, Maya seeks her ‘perfect’ mother’s (a renowned psychiatrist) help and support to overcome her post-natal struggles. Unwittingly she realizes that her mother is fighting old age and dementia. By using the theories of Susan Maushart’s ‘mask of motherhood’ and Andrea O’ Reilley’s ‘empowered mothering’ this paper seeks to find out how Maya’s postpartum depression and her mother’s dementia brings out the inherent ‘maternal guilt’ and the faltering corporeality of motherhood and gives an empowered definition of mothering.
Exploring the Alt News Phenomenon: A Case Study of One of India’s Most Prominent Fact-Checking Campaigns
Authors:   Fellow of the Royal Society of Arts, U.K, Valiyamattam Rositta Joseph
Published: January 2025

The AI-powered digital revolution of the 21st-century world has greatly exacerbated the problem of fake news, which has been a menace to humankind since ancient times. Misinformation and disinformation have infiltrated every sphere of contemporary human life, causing immense damage in the social, political and economic arenas. In this context, various humanities and social sciences disciplines have taken up the challenge of combating fake news. Numerous studies have found that instead of mere damage control, preventive education against fake news proves to be much more effective (for instance, Nolan Higdon’s The Anatomy of Fake News: A Critical News Literacy Education, 2020). This paper presents an analytical case study of Alt News, one of India’s most prominent fact-checking and anti-fake news campaigns. Its co-founders were nominated for the 2022 Nobel Peace Prize for their courageous journalism in the face of tremendous political pressure. Interestingly, Alt News has initiated a media and digital literacy campaign by harnessing various humanities and social sciences disciplines, starting with curricular interventions in schools and colleges. While performing a SWOT analysis of Alt News, this paper seeks to highlight interdisciplinary humanities and social science educational initiatives that can help control and potentially end the fake news phenomenon.

For over a century, cinema has been an influential medium through which stories are told, and culture is expressed. Stories come to life through filmmaking and exploring various themes, experiences and perspectives. Film’s visual and narrative elements can shape public opinion, subvert social conventions, provoke thinking and significantly impact the culture and social discourse. This study examines the representation of transgender individuals in Malayalam cinema, analysing the evolving narrative landscape and its societal impact. Regardless of a rich cinematic history dating back to the 1930s, Malayalam films have only recently begun to include transgender themes with depth and sensitivity. The study scrutinises early depictions that often resorted to stereotypes and comedic mockery, contrasting them with contemporary portrayals that uphold understanding and acceptance. By dissecting specific films, this work reveals the changing tides in cultural perception and points out the importance of responsible storytelling in media. This study calls for a continued push towards authentic and respectful representation, emphasising the transformative potential of cinema in shaping public attitudes towards the transgender community. This study used historical, content, and discourse analysis as methodology and representation theory as the theoretical framework to examine the portrayal of transgender in Malayalam cinema.

Authors:   Human Sciences Research Center, International Institute of Information Technology Hyderabad, Naidu Swamy , Alam Aniket
Published: January 2025

Celebrated for its stunning landscapes, Himachal Pradesh has become a renowned tourist destination, experiencing a surge in visitors. Since the 1980s, the state has witnessed significant economic growth, supported by a boom in the tourism industry. This research aims to correlate tourism with economic growth and analyse the unique tourism-driven development of Himachal Pradesh. We used urban built-up areas in key tourist hotspots as a proxy, and employed Geographic Information Systems (GIS) and visual interpretation techniques to examine urban growth around Solang Valley, Bhagsunag Temple, Chail, Kufri, and Khajjiar from 1990 to 2020. Historical Landsat satellite imagery was utilised to quantify urban built-up changes. The findings revealed a significant increase in built-up areas within all tourist buffer zones, with Bhagsunag Temple showing the most dramatic growth (~1000%). Non-tourist locations with similar demographics showed an average increase of 55%, compared to 427% in tourist buffers. This study demonstrates that built-up areas have expanded more rapidly in tourist areas, highlighting the substantial impact of tourism on urban growth. These findings suggest the need for further exploration into tourism, policy studies, and economics in Himachal Pradesh.

Authors:   Research Scholar, Techno India University, West Bengal & Faculty, PG Dept of English, Bhatter College, Dantan, Das Pragati , Bandyopadhyay Mita ,   Assistant Professor, Techno India University, West Bengal
Published: January 2025

Visual art plays a crucial role in the music industry; it is not merely a marketing tool but also a fundamental part of the narrative and emotional impact of music. This is especially true for Leonard Cohen, who practiced visual art himself and had an acute sense of the visual elements of his album covers. This article examines the interrelationship between the visual elements of Cohen’s album covers and the music within. By analyzing five representative albums spanning nearly 50 years—Songs of Leonard Cohen (1967), New Skin for the Old Ceremony (1974), I’m Your Man (1988), Ten New Songs (2001), and You Want It Darker (2016)—this study demonstrates how Cohen meticulously crafted the album covers as intellectual extensions of his poetic vision. Through archival research and visual and textual analysis, this paper explores both the general cultural and technological contexts that influenced the visual aesthetics of the albums, and the personal intellectual contexts responsible for variations in design. Thus, the study presents a comprehensive analysis of the visual aesthetics of Cohen’s albums that began amidst the cultural upheaval of the 1960s and concluded in the second decade of the present century, a period during which the production, distribution, and consumption of music underwent a complete transformation.

Authors: Wang He , Terreni Marco , Sollogoub Matthieu , Zhang Yongmin
Published: January 2025

The understanding of glycans, the third life chain, is widely desired. Naturally,
the glycoconjugates are found in heterogeneous forms due to the enzyme competition
in the same process. As a result, the synthesis of homogeneous glycans has become one
of the trending research topics. In this review, orthogonal protection strategies were summarized
to overcome the difficulties, such as the numerous hydroxyl groups of oligosaccharides
and stereoselectivities during glycosylations. A variety of synthetic glycomics,
including glycoproteins, glycolipids, and newly discovered glycoRNAs, were also
presented. Their applications were categorized by different diseases, which elucidated
the great potential of glycans as drug candidates in the next generation.
Selective Catalytic Synthesis of Hydrocarbons Based on C60 Fullerene and Adamantane in the Presence of Pd(Pph3)2Cl2 and their Sonochemical Isomerization
Authors: Akhmetov Arslan Rifkhatovich , Kinzyabaeva Zemfira Sabitovna
Published: January 2025

A series of asymmetrical spirohomo- and methanofullerenes were synthesized for the first time in
reactions of selective cycloaddition of adamantane diazo compounds to C60 fullerene in the presence of the catalyst
Pd(PPh3)2Cl2. Adamantane diazoalkanes were obtained in situ in the oxidation reactions of adamantane
hydrazones with manganese oxide MnO2. It has been established that the presence of adamantyl on the methylene
bridge (in the case of symmetry of the spirocyclic fragment), methyl and ethyl substituents, or no substituents
(in the case of asymmetry of the spirocyclic fragment) leads to the formation of exclusively [5,6]-open
isomers (homofullerenes); when the hydrocarbon radical (butyl and nonyl radical) is extended on the methylene
bridge of the asymmetric spirocyclic fragment, only [6,6]-closed isomers (methanofullerenes) are
formed. All homofullerenes obtained in this work do not isomerize into the corresponding methanofullerenes
under thermal conditions (180°C, 100 hours). Homofullerenes containing an adamantyl radical (in the case of
symmetry of the spirocyclic fragment) or not containing substituents (in the case of asymmetry of the spirocyclic
fragment) on the methylene bridge do not isomerize into the corresponding methanofullerenes under the
influence of ultrasound (room temperature, 5 hours). For the first time, sonochemical isomerization of spirohomofullerenes
containing electron-donating methyl and ethyl groups on the methylene bridge into methanofullerenes
was carried out under mild conditions (1.5 hours, toluene, room temperature, air). Atmospheric
oxygen does not affect the isomerization reaction. The presence of CCl4, which forms CCl3
● radicals during
sonolysis, suppresses isomerization reactions, which indicates the participation of radical particles in the rearrangement
process. A probable mechanism for the structural rearrangement of homofullerenes into methanofullerenes
under the action of ultrasound is proposed.
Atrial Fibrillation-Related Bradycardia and/or Bradycardia-Related Atrial Fibrillation: When and How to Intervene
Authors: Manolis Antonis A. , Manolis Theodora A. , Manolis Antonis S.
Published: January 2025

Introduction/Objective:

Atrial fibrillation (AF) could present with slow ventricularresponse;
bradycardia could facilitate the emergence of AF. The conviction that one “does not succumb”
from bradycardia as an escape rhythm will emerge unless one sustains a fatal injury following
syncope is in stark difference with ventricular tachyarrhythmia (VA), which may promptly cause
cardiac arrest. However, this is not always the case, as a life-threatening situation may emerge during
the bradycardic episode, i.e., the development of bradycardia-induced VAs, which could be fatal if
there is no prompt intervention.

Methods:

An extensive review of the literature was undertaken with key words including but not
limited to AF, bradycardia, bradyarrhythmia, AF and bradycardia, slow ventricular response, sinus
node dysfunction, sick sinus syndrome, tachycardia-bradycardia syndrome.

Results:

AF is the commonest cardia arrhythmia worldwide and may be part of sick sinus syndrome,
commonly presenting as bradycardia-tachycardia syndrome. Importantly, bradycardia-related cardiomyopathy
and heart failure, as well as an adverse influence on brain function, may all be eluding
consequences of this type of syndrome. Bradycardia could be the inciting mechanism for the occurrence
of AF, and when the bradycardia is eliminated, AF may not recur. The bradycardia-related
long-short-long sequence triggering VAs can be averted by pacing at rates ~80-110 bpm either via
temporary or permanent pacing as needed.

Conclusion:

Balancing the benefits and risks of bradycardia together with other risks of antiarrhythmic
drug and/or pacing management of AF versus those of catheter ablation is indeed a vexing
problem; all these issues are herein discussed, tabulated, and pictorially illustrated.

Authors: Ali Souandaou Athoumani , Özcan Gül , Bulan Nihal Ömür
Published: January 2025

Background:

Saffron (Crocus sativus), also known as Red Gold has shown anticancer
activity, but the molecular mechanisms underlying its potential therapeutic effects are not fully understood.

Objective:

This study investigates the anticancer effects of safranal on cervical cancer, one of the
most common cancer types in women worldwide, and elucidates the molecular mechanism underlying
these effects through bioinformatics analysis RNA-sequencing.

Method:

The molecular mechanisms and key genes underlying the antiproliferative effect of safranal
(400μM) on cervical cancer cells were determined with RNA sequencing bioinformatics analysis.

Results:

The total number of expressed genes in HeLa and C- 4 I was determined to be 1101 and
1190, respectively after 24 hours of incubation of safranal. KDA showed the key driver genes
EIF2AK2, USP18, PARP14, GBP1, SAMD9L, SP110, DDX60, IFI44L and MX2 of the HeLa
group, while in the C- 4 I group, key driver genes are DNAJC3, DNAJB9, DNAJB8, SRPX2,
PRSS8, MRC2, IER2, RPS19BP1, CRELD2 and SDF2L1. KEGG and GO analysis revealed that
safranal induced cell arrest in the G1 phase, cell death apoptosis, and necroptosis in cervical cancer
cells. These antiproliferative effects were shown based on regulated signaling pathways:
MAPK, TGF-beta, p-53, TNF and FoxO signaling pathways.

Conclusion:

Based on the results obtained by RNA sequencing, it can be concluded that safranal
has a potential antiproliferative effect and could be used in the clinic as an anticancer agent.

Authors: Mollick Mirazuddin , Rahaman Syed Mustafizur , Ashique Sumel , Bhowmick Mithun , Bhowmick Pratibha , Pal Radheshyam , Kumar Prashant
Published: January 2025

Superparamagnetic iron oxide nanoparticles have gained considerable attention in drug
delivery due to their superparamagnetic characteristics. SPIONs have a greater surface-to-volume
ratio, size, superficial chemistry, and superparamagnetic characteristics, which allow them to be
covered by external magnetic fields. These properties make SPIONs promising nanoparticles for
drug delivery systems. A great advantage of the superparamagnetic characteristics is magnetic
properties. SPIONs are magnetic and thoroughly demagnetized when the field of the electromagnet
is pulled out. These characteristics permit their targeted delivery to a particular tissue or cell
following a magnetic field. Furthermore, SPIONs can be fabricated with particular ligands, such
as peptides or antibodies, to increase their efficiency in desired cells or tissues. This permits delivery,
particularly to the desired cell type, increases therapeutic activity, and reduces off-target effects.
Moreover, SPIONs exhibit imaging characteristics. However, this review highlights the capabilities
of SPIONs for targeted drug delivery to reduce tumor cell toxicity.
Serum Cortisol and Cardiovascular Disease Risk-A Potential Biomarker
Authors: Oo Wei Jet , Lim Chooi Ling , Goh Mun Hon , Koh Rhun Yian
Published: January 2025

Cardiovascular Disease [CVD], the leading cause of death globally, poses a
significant burden on the healthcare sector. Its association with stress and Cushing’s Syndrome
has driven cortisol, the ‘stress hormone,’ to be a potential candidate in determining CVD risk.
Cortisol synthesis and release through the hypothalamic-pituitary-adrenal [HPA] axis are
regulated by several hormones and receptors involved in the pathological cascade towards CVD.
Evidence suggests that metabolic syndrome plays a major role in cortisol-mediated CVD risk.
On the other hand, non-metabolic features are also implicated when the association between
cortisol and CVD risk remains significant upon normalisation of metabolic parameters.
Correspondingly, the treatment for hypercortisolism is often found effective in lowering CVD
risk. Despite available evidence, several factors continue to hinder the clinical use of cortisol as
a risk biomarker for CVD. This review provides an insight into the role of serum cortisol in
CVD progression and risk, with emphasis on the mechanistic features and parameters.
Identification, Isolation, Structure Characterization, and Chromatographic Separation of a New Highly Analogous Impurity of the Ubrogepant
Authors: Ummiti Kumarswamy , Vanga Nagavardhana Reddy
Published: January 2025

Background:

Ubrogepant is a regulated peptide receptor antagonist associated with the
calcitonin gene, granted approval in the United States for the specific treatment of migraine
headaches.

Objective:

An impurity found in the alkali hydrolysis of drug dosage forms has a structure very similar
to that of ubrogepant. This research aims to characterize this analogous impurity utilizing NMR
and LC-MS spectroscopy tools. Moreover, it is critical to develop an extremely sensitive and
superior resolution analytical procedure for identifying and determining the amount of analogous
impurity in pharmaceutical products.

Method:

The ubrogepant impurity was identified using an optimized chromatographic method that
relies on reversed-phase HPLC with UV detection. This technique utilized a charged surface hybrid
(CSH) technology column operating in gradient elution mode. A mixture of A-channel (0.1%
trifluoroacetic acid) and B-channel (acetonitrile and water, 80:20% v/v) constituted the eluent. The
analogous impurity was isolated through fraction collection, purified using flash chromatography,
and characterized using NMR (1D and 2D) and LC-MS.

Results:

The analogous impurity was successfully separated from the ubrogepant peak with a resolution
above 2.0. The concentration of the impurity was approximately 10% compared to the ubrogepant
peak after alkaline stressing at room temperature for 30 minutes. NMR (1D 13C NMR and
1H, 2D HMBC, HSQC, NOESY, and COSY) and LC-MS analysis characterized the ubrogepant
impurity, revealing it to be an epimer of ubrogepant. The developed approach was highly sensitive,
allowing for the quantification of the ubrogepant impurity even at a concentration of 0.2 μg/mL.

Conclusion:

The approach demonstrated a remarkable degree of precision, linearity, specificity, and
accuracy. This new impurity deserves special attention because of its striking similarity to the active
ingredient, ubrogepant.

Data-driven modeling approaches for pressure drop prediction in a multi-phase flow system
Authors: Alyazidi Nezar M. , F. Bawazir Aiman , AL-Dogai Ala S.
Published: January 2025

Accurate prediction of pressure drops in multi-phase flow systems is essential for optimizing processes in industries such as oil and gas, where operational efficiency and safety depend on reliable modeling. Traditional models often need help with the complexities of multi-phase flow dynamics, resulting in high relative errors, particularly under varying flow regimes. In this study, we simulate a comprehensive multiphase flow experimental data collected from the lab. This study presents innovative methods for accurately modeling pressure drops in multi-phase flow systems. It also studies the complicated dynamics of multi-phase flows, which are flows with more than one phase at the same time. It does this by using two different data-driven models, nonlinear ARX and Hammerstein-Wiener, instead of neural networks (NNs), so that the models don’t get too good at fitting environments with lots of changes and little data. Our research applies system identification approaches to the intricacies of this domain, providing new insights into choosing the best appropriate modeling strategy for multi phase flow systems, taking into account their distinct properties. The experimental results show that the nonlinear Hammerstein-Wiener and ARX models were much better than other methods, with fitting accuracy rates of 81.12% for the Hammerstein-Wiener model and 86.52% for the ARX model. This study helps the creation of more advanced control algorithms by providing a reliable way to guess when the pressure drops and showing how to choose a model that fits the properties of the multi-phase flow. These findings contribute to enhanced pressure management and optimization strategies, setting a foundation for future studies on real-time flow control and broader industrial applications.
Understanding the regenerating capacity on photodegradation of methylene blue of titania supported mesoporous silica with the aid of gelatin-P123 as bitemplate
Authors: Ulfa Maria , Hasanah Ika Uswatun , Bahruji Hasliza
Published: January 2025

Mesoporous silica (MS) was successfully synthesized via the sol-gel method using gelatin-P123 as a bi-template under hydrothermal reaction conditions at 100 ºC for 24 h, followed by calcination at 550 ºC for 5 h. The amount of TiO? in MS was adjusted to 1, 5, and 10% (w/w) and characterized using XRD, FTIR, SEM-EDX, N? adsorption-desorption, and UV-Vis. The crystallinity of the samples increased with higher TiO? content, as confirmed by XRD data. SEM analysis revealed that the morphology of MS and TiO?/MS was cylindrical, with a particle size distribution of 0.4–0.6 µm. The surface area of MS was 500.8 m²/g, which decreased to a range of 369.6–454.8 m²/g after TiO? modification, while the pore diameter increased from 28.22 to 34.61 Å. The adsorption efficiency for methylene blue photodegradation reached a maximum value of 95%, demonstrating excellent catalytic performance. Thermal regeneration proved to be a promising strategy to recover the photocatalytic efficiency of TiO?/MS for more than five cycles. Furthermore, thermal regeneration and the reuse of catalysts in wastewater treatment systems provide cost-effective solutions for pollutant removal.

The production of vegetable-based fuels has intensified in recent years due to the decreasing availability of fossil fuels and their environmental impacts. This study explores the synthesis, characterization, and application of nickel-molybdenum (NiMo) bimetal-dispersed silica catalysts for converting used palm cooking oil into liquid biofuels. The catalysts were synthesized using the wet impregnation method, incorporating Ni and Mo metals at concentrations of 1, 2, and 3% by weight of silica derived from rice husk ash. Impregnation of the silica with Ni and Mo metals increased its acidity, with the NiMo/SiO? 2 catalyst exhibiting the highest acidity value of 4.34 mmol/g. This catalyst also demonstrated the largest specific surface area and total pore volume, measured at 205.51 m²/g and 0.88 cm³/g, respectively. Hydrocracking of used palm cooking oil into liquid biofuels was performed at an optimum temperature of 450 °C with catalyst-to-feed weight ratios of 1:100, 2:100, and 3:100 for 1 h by hydrogen gas supply of 20 mL/min. Catalyst activity tests revealed the highest mass percentage of liquid product, 23.3%, at a ratio of 1:100 (w/w), with a biofuel yield of 20.34%, comprising 14.20% gasoline and 6.14% diesel. By utilizing biomass waste as both a catalyst and feedstock, this study presents a sustainable approach to reducing the carbon footprint and promoting environmental balance.

Sidoarjo mud is a natural material resulted from an unusual natural phenomenon and is rich in silica contents. So far, no studies have been reported about mesoporous silica from Sidoarjo Mud, which is a supported catalyst for one-step conversion to biodiesel. This study aims to explore synthesis, characterization, and applications to demonstrate the heightened activity and selectivity in the esterification- transesterification of waste palm oil into biodiesel, utilizing a one-step method aligned with the principles of green chemistry using two bifunctional catalysts (Ni/MS - NH2/MS and Ni-NH2/MS). The bifunctional catalysts were prepared by means of hydrothermal, wet impregnation, and grafting methods. The highest biodiesel yield (78.77%) was achieved under the condition of 65 °C, 3 h, methanol to oil ratio 21 : 1, and 3wt% of Ni/MS - NH2/MS as the catalyst. The catalyst was able to yield a conversion level as good as ~72% in the 3rd cycle after regeneration. The research demonstrates the industrial relevance of the catalyst, offering a sustainable solution for biodiesel production and waste management.

This study details the nickel-substituted cobalt ferrite nanoparticle employing natural fine sediment (NiCFO-fs) annealing temperature dependency of crystalline and magnetic characteristics. The NiCFO-fs nanoparticles were prepared by the coprecipitation method with varying annealing temperatures (200-500°C with increment of 100°C for five hours). As a comparison, Ni-CFO was also synthesized using pure analytical chemicals (NiCFO-pa). The XRD results showed that the whole Ni-CFO nanoparticles established an inverse spinel face center cubic (fcc) order according to space group Fd-3m for both NiCFO-fs and NiCFO-pa. There was no additional peak, indicating that Ni2+ cations successfully substituted in cobalt ferrite nanoparticles. In case of NiCFO-fs nanoparticle samples, a crystallite size (D) decreased with the increasing annealing temperature (Ta), namely 45.72 nm, 37.35 nm, 25.95 nm, and 20.51 nm. In contrast to NiCFO-pa, the D increased with the increase of the Ta, i.e., 19.67 nm, 20.74 nm, 21.99 nm, and 23.33 nm. Meanwhile, FTIR results showed the presence of metal-oxygen bonds at 551-586 cm-1 and 384-391 cm-1 at tetrahedral (k1) and the octahedral (k2) sites for both NiCFO-fs and NiCFO-pa nanoparticles samples. The VSM result showed that a narrow hysteresis curve was observed for the NiCFO-fs sample compared to NiCFO-pa. The NiCFO-fs nanoparticles owing the smallest coercive field (HC) of 79.5 Oe were attained for the Ta of 300°C. In case of NiCFO-fs samples, magnetization saturation (MS) decreased with the increase of the Ta in contrast to NiCFO-pa samples. Here, the redistribution of two and three plus ions in the sub-lattice k1 and k2 locations should be encouraged by the Jahn-Teller phenomenon through strain-induced magnetism. The findings of the antibacterial test indicated that the potential of NiCFO based on natural materials (fine sediment) was higher than that of NiCFO based on pure analytical chemicals. This result was also supported by the emergence of ZOI magnitudes for all NiCFO-fs materials compared to NiCFO-pa that was only at Ta = 300°C.

This study aims to synthesize and evaluate the inhibitory activity of thymol derivatives targeting ?-glucosidase using in vitro and in silico studies. Ten thymol derivatives (2-11) including five new thymol-fused chalcones (7-11) were successfully synthesized. Among them, four compounds (4, 8, 9, 11) showed the best inhibitory activity with IC50 values of 18.45, 13.75, 8.86, and 10.67µM compared with acarbose (IC50 = 832.82 µM), respectively. The kinetic study of three new thymol-fused chalcones (8, 9, 11) exhibited a competitive inhibition. Molecular docking demonstrated the predicted interactions between ligand (8, 9, 11) and ?-glucosidase, which are responsible for inhibiting the enzyme's catalytic abilities. Furthermore, molecular dynamics simulation of the enzyme-ligand 9 complex indicated that this complex was stable in aqueous condition. This research contributes significantly to the understanding of thymol-fused chalcones that may have therapeutic potential and their possible application in the treatment of type 2 diabetes mellitus (T2DM) for further study.

Zeolitic imidazolate framework (ZIF) is renowned for its high adsorption capacity and frequently adsorbs organic pollutants. However, its high band gap energy has limited its photocatalytic activity, thus necessitating a modification for enhance performance enhancement. This study focuses on developing a ZIF-7 composite material that integrates adsorption and photocatalysis to remove volatile organic compounds (VOCs), particularly hexanal. Modifications were made by incorporating ZnO, TiO2, and ZnO/TiO2 via a solvothermal method using dimethylformamide (DMF). ATR-FTIR analysis was employed to monitor any changes in peak intensity related to the C=O vibrations of hexanal around 1700 cm-1. The results showed that all samples effectively adsorbed hexanal, reducing peak intensity after UV irradiation, and confirming successful photocatalysis. Notably, TiO2@ZIF-7 exhibited the highest photocatalytic performance with 88.06% degradation efficiency. This study confirms that the ATR-FTIR method can be used to monitor the success of adsorption and photocatalysis and shows the potential for developing composite materials to remove VOCs such as hexanal.

Today, the utilization of endophytic diazotrophic bacteria (EDB) purposely to minimize the application of urea fertilizer (UF), and enhance soil fertility, crop quality and corn yield in sustainable agricultural practices is an inevitable trend. The experiment was arranged outside the AGU green house of Agriculture Research Center, An Giang university, Vietnam, which consisted of two factors: (i) two EDB species [Bacillus sp.  NTLG2-20 (Bacillus A) and Bacillus arybhattai strain CM44 (Bacillus B)] and (ii) three UF ratios (0.0, 100 and 200 kg N ha-1) and four replications. Research data presented that the fresh cob yield of Bacillus A was found 4.0% higher than that of Bacillus B and 12.7% than that of non EDB inoculation. Furthermore, the inoculation of Bacillus B had 9.02% higher fresh cob yield compared to non-inoculation. The 50% reduction of UF application combined EDB addition obtained the fresh cob with no significant difference, compared to 100% recommended urea application. The interaction between the effectiveness of EDB inoculation and UF reduction was clearly different in favor of corn grown on sandy loam soils with low nutrient contents. Both Bacillus A and Bacillus B had the abilities of high yield and good nitrogen fixation with the potential to simultaneously improve soil fertility and corn yield. The results of this study demonstrated that two strains of Bacillus A and Bacillus B have the potential to promote the growth and increase the yield of peanuts, and it should be suggested for future biological fertilizer production.
