De te narratur fabula: la metalidad militar del neoliberalismo y las posibilidades imaginales del Golpe leídas desde México
Authors: Aragón Moreno Dante Ariel
Published: November 2023

En el presente artículo se piensa la relación entre el golpe, los problemas de la re-presentación y la militarización neoliberal a través de varias imágenes, entre las que la del tanque de guerra será primordial para reflexionar acerca del origen violento del nuevo régimen económico y vital que se desplegó con el golpe. Lo anterior se enmarca desde el imaginario político de México en los años setenta, particularmente a través del régimen del presidente Luis Echeverría y su singular relación con el elemento militar. La multiplicidad de miradas mexicanas sobre el golpe chileno está mediada por las imágenes. En esa miríada de elementos, existe un resto incontable, anónimo y excesivo: lo plebeyo.
Chile, año cero. La imagen-esperanza en el cine de la Unidad Popular
Authors: Taccetta Natalia
Published: November 2023

Desde una perspectiva teórica cercana al giro afectivo, estas páginas se proponen reflexionar sobre la construcción de la esperanza en parte del cine de la Unidad Popular chilena durante los primeros meses del gobierno de Salvador Allende. No se revisan en profundidad filmes sobre los que se ha dicho todo, sino que se rastrea en algunos lo que se da en llamar la imagen-esperanza. Para ello, se eligen tres filmes cuya única nota común es corresponderse de modos diversos con una suerte de «año cero»: El primer año de Patricio Guzmán (1972), Voto + fusil de Helvio Soto (1971), y Palomita blanca de Raúl Ruiz, terminada en 1973 antes del golpe de Estado, y reeditada y estrenada en 1992. En los tres, es posible tematizar una esperanza que parece plantear más interrogantes que opciones tranquilizadoras aun cuando, como decía Guzmán en el diario de filmación de El primer año, «Chile era una fiesta».
A Case of Camphor Toxicity in a Toddler: All on Skin is Not Safe
Authors: Ramya R , Harish N , Sundari S
Published: November 2023

Paediatric population is very vulnerable to toxicities resulting from exposure to many traditional medicines, which are often used in our culture as treatments for various ailments. People are unaware of the untoward complications arising from the toxicity of these native medicines, especially camphor. Adding to the problem, parents often believe that native medicines, particularly when applied topically, are safe for children. Here, the author reported a previously healthy 2-year-old child who had multiple episodes of seizures after the mother applied topical camphor oil for five days to relieve the child’s symptoms of nasal congestion. While there is no clear data on the concentration and duration of topical camphor exposure that causes toxicity in children, the case report highlighted the possibility that younger children may develop toxicity in a relatively short period of exposure. In this modern era of evidence-based medicine, it is important to raise awareness among the public, especially parents, that not everything applied to the skin is safe for children, as their anatomy differs from that of adults.

Published: November 2023

Coronavirus Disease-2019 (COVID-19) can be classified as a respiratory disease that ranges from pneumonia to critically ill cases. Extracorporeal Membrane Oxygenation (ECMO) is a therapeutic procedure that can treat severe cases of respiratory failure. Hereby, the authors present, a 28-year-old case of Acute Respiratory Distress Syndrome (ARDS) young patient with COVID-19 on ECMO therapy, presenting with complaints of weakness, decreased mobility and function, and depression. The patient has received physical therapy interventions during the hospitalisation period. Respiratory, mobility, activity level, and psychological assessments were done before and after treatment using blood gases, the Intensive Care Unit (ICU) Mobility Scale, the University of Michigan scale, and the Hamilton Anxiety and Depression Rating Scale, respectively. There was an improvement in respiratory function, mobility (scores increased from 0 to 1), activity level (scores increased from 0 to 3), and psychological well-being (depression scores decreased from 18 to 15, and anxiety scores decreased from 20 to 14) after physical therapy. The treatment resulted in better recovery and prevented the worsening of the COVID-19 disease scenario.

Published: November 2023

Introduction: With modern advances, Ultrasonography (USG)- guided regional block techniques have improved nerve blockade with lesser drug usage and maximum safety for patient care. The widely appreciated outpatient surgical care has compelled us to apply the fastest and safest anaesthesia technique. For lower limb surgeries, USG-guided Sciatic Femoral Nerve Block (SFNB) is an emerging alternative to Spinal Anaesthesia (SA). Aim: To compare the safety and efficacy of both techniques in terms of haemodynamic stability, quality of block, and postoperative analgesia. Materials and Methods: A randomised double-blind study conducted at GCS Medical College, Hospital, and Research Centre, Ahmedabad, Gujarat, India, on 80 patients aged 18 to 70 years of either sex, with American Society of Anaesthesiology (ASA) Grade 1 to 3, undergoing below-knee surgeries was divided into two groups. Group A received USA with 1.5 mL hyperbaric inj. ropivacaine 0.75%, and Group B received USGguided SFB with inj. ropivacaine 0.5% 30 mL (15 mL for sciatic nerve and 15 mL for femoral nerve block). Preparation Time (PT), Surgical Anaesthesia Time (SAT), haemodynamic changes, quality of block, Longevity of Anaesthesia (LoA), time of first rescue analgesia, time of spontaneous urination, readiness to discharge, and patient satisfaction were recorded. The statistical analysis was carried out using Statistical Package for Social Sciences version 23.0 (SPSS Inc., Chicago II, USA). The p-value was derived by unpaired t-test and Chi-square test. Results: PT and SAT were higher in Group B (12.10±2.02 mins and 15.74±1.58 mins) than in Group A (6.15±1.12 mins and 8.23±1.45 mins). LoA time and time to first rescue analgesic were higher in Group B (284.10±54.44 mins and 265.71±33.69 mins) than in Group A (138.75±23.30 mins and 132.40±17.41 mins). Time to first spontaneous urination and readiness to discharge were shorter in Group B (136.42±18.40 mins and 158.39±10.78 mins) than in Group A (162.20±26.54 mins and 181.53±18.18 mins). Haemodynamic stability was excellent in both groups with no significant fluctuation. Motor blockade of Bromage 3 grade was achieved in 40 and 38 patients in Group A and B, respectively. The development of VAS score >3 was faster in Group A than in Group B (35 versus 2) at the end of three hours. No adverse events were observed in any patient. Conclusion: USG-guided SFB offers a safe and efficient alternative to Unilateral SA (USA) with satisfactory blockage, stable haemodynamics, and better postoperative analgesia for below-knee surgeries.
Effect of Fragrance on Electroencephalographic Waves and Blood Pressure during Problemsolving Activity among Healthy College Students: A Cross-sectional Study
Authors: Jain Rahul S , Rekha D , Das Subhasis
Published: November 2023

Introduction: The influence of fragrance, such as perfumes and room fresheners, on the psycho-physiological activities of humans has been known for a long time. However, very few studies have been conducted to investigate its effects when a person is under stress. Aim: To determine the effect of fragrance on electroencephalographic waves and blood pressure during a problem-solving activity. Materials and Methods: This cross-sectional study was conducted among 55 college students aged 18-22 years in the electrophysiology laboratory of the Department of Physiology at Pondicherry Institute of Medical Sciences, Puducherry, India from May 2019 to June 2019. After obtaining a history and conducting an olfactory examination, participants were asked to be in the electrophysiology laboratory to record Electroencephalogram (EEG) and blood pressure before and after exposure to fragrance for five minutes. Data were statistically analysed using Fischer’s-exact test and paired t-test. Results: The study included 55 college students (38 males, 17 females) with a mean age of 19.46±1.004 years. EEG changes were compared at rest, including alpha waves (n=55), beta waves (n=55) during the problem-solving activity, and theta waves (n=55) during exposure to lavender fragrance. EEG changes were analysed using Fischer’s-exact test, and the results were statistically significant (p-value<0.001). The mean±Standard Deviation (SD) of Systolic Blood Pressure (SBP) during fragrance exposure (110±11.82 mmHg) vs solving the puzzle (123.44±15.97 mmHg) was significantly lower (p-value=0.048*). The mean±SD of Diastolic Blood Pressure (DBP) during fragrance exposure (74.44±11.27 mmHg) vs solving the puzzle (74.40±12.92 mmHg) was slightly higher, but not statistically significant (p-value=0.516). Conclusion: The present study demonstrated that the use of fragrance can have a relaxing effect on the mind and body, as it increases theta wave activity in the brain and significantly reduces SBP.

Authors: . Neha , Das Aseema , Gogoi Amilee , Chaliha Bhargav
Published: November 2023

Introduction: Hypertensive disorders of pregnancy are one of the most common obstetric pathologies, affecting approximately 8-10% of all pregnancies worldwide, including entities like preeclampsia and eclampsia. Preeclampsia increases the risk of maternal morbidity and mortality, foetal mortality, and preterm birth. Early identification of preeclampsia and eclampsia helps in the effective management and favourable outcome of pregnancy. Aim: To determine the relationship between platelet parameters, namely Platelet Count (PC) and Platelet Distribution Width (PDW), with preeclampsia and eclampsia. Materials and Methods: A hospital-based analytical crosssectional study was conducted in the Department of Pathology in collaboration with the Department of Obstetrics and Gynaecology, including 100 pregnant women attending the antenatal clinic in Jorhat Medical College and Hospital, Jorhat, Assam, India, for a duration of one year (from June 2021 to July 2022). Pregnant women meeting the inclusion criteria were selected and divided into two broad groups: a comparison group comprising normotensive pregnant women (n=50) and a study group (n=50), which further included subgroups of preeclamptic women (n=35) and eclamptic women (n=15). A 5 mL venous blood sample was drawn and collected in an Ethylenediaminetetracetic acid (EDTA) vial from both groups and analysed using a six-part fully automated haematology cell counter (SYSMEX XN-550) for PC and PDW. Changes in PC and PDW were compared between the two groups using a student t-test with GraphPad software. A p-value of <0.05 was considered statistically significant. Results: The mean PC in preeclampsia was 185.714±69.56×103 / μL, while in eclampsia, it was 147.53±56.927×103 /μL. The mean value of PDW in preeclampsia was 18.4314±4.184 fL, while in eclampsia, it was 14.86±3.854 fL. A decrease in PC was found to be statistically significant in eclampsia (p-value <0.001). PDW was statistically significantly different among normotensive, preeclamptic, and eclamptic participants (p-value <0.001). The increase in PDW was higher in eclamptic patients compared to preeclamptic patients. Conclusion: Hence, the estimation of PC and PDW can be used as a screening test for the early identification of preeclampsia and eclampsia. Platelet parameters may act as an indicator of preeclampsia and eclampsia. The prognosis of preeclampsia and eclampsia in pregnant women can also be assessed, making them effective prognostic markers as PDW correlates with disease severity. Moreover, these indices are cost-effective and easily available.

Published: November 2023

This work examined the decadal trends and variability of rainfall data over Nigeria from 1979 to 2021 (42 years). Observational monthly rainfall data was obtained from the Nigerian Meteorological Agency (NiMET). The data underwent statistical analysis to illustrate its spread and variability using metrics such as mean, standard deviation, and coefficient of variation, linear regression was applied to reveal the trends or changes over time, the coefficient of correlation was employed to assess the statistical relationships of rainfall across the distinct climate regions of Guinea, Savanna, and Sahel, respectively.  There were varying levels of annual and seasonal rainfall across the regions, with Port Harcourt receiving the highest annual and seasonal rainfall in the Guinea region. Sokoto and Maiduguri exhibit the highest annual rainfall in the Sahel region. The decadal analysis highlights the fluctuations in rainfall anomalies, as some decades showed surplus rainfall while others displayed negative deviations, indicating the changing nature of regional rainfall patterns.
Comparison of Microscopy, Culture and Molecular Methods for Diagnosing Gonorrhea
Authors: Lachyan Abhishek , Muralidhar Sumathi , Verma Priyanka , Rajan Santhosh , Sharma Devanshi , Joshi Naveen , Khunger Niti
Published: November 2023

Gonorrhea, a sexually transmitted infection caused by Neisseria gonorrhoeae, continues to be a significant global public health concern. The timely and accurate diagnosis of this infectious disease is crucial for its effective management. Traditional methods, especially culture, were historically considered the gold standard for diagnosing gonorrhea. However, the introduction of nucleic acid amplification tests (NAATs), such as Real-Time PCR, has revolutionized diagnostic approaches. Currently, the Center for Disease Control and Prevention (CDC) recommends NAAT as the primary diagnostic method, with culture reserved for specific cases, particularly for testing antimicrobial susceptibility in instances of suspected treatment failure. The International Union against Sexually Transmitted Infections (IUSTI) provides guidelines for the use of NAAT or culture, depending on clinical scenarios. This study conducted a retrospective comparative analysis of various diagnostic methods at the Apex Regional STD Centre in New Delhi, India, spanning from January 1, 2022, to December 31, 2022. Culture, Real-Time PCR, and smear examination were compared for the diagnosis of gonorrhea. A total of 33 samples were included in the analysis, with the following percentages: culture (92.02%), PCR (100%), and smear examination (100%). An intriguing finding was that 7.98% of samples were culture-negative but PCR-positive, highlighting a significant disparity between the two methods. This observation underscores the limitations of relying solely on culture for gonorrhea diagnosis and the potential consequences, including treatment delays, disease transmission, and the development of antibiotic-resistant strains. In summary, this study underscores the critical need for accurate and reliable diagnostic methods for gonorrhea. It emphasizes the evolving diagnostic landscape, with NAATs emerging as essential tools. The findings from multiple studies stress the complementary roles of different diagnostic methods and the necessity of adapting to evolving diagnostic techniques. This research highlights the importance of collaborative approaches to enhance accuracy and address the evolving challenges of gonorrhea diagnosis. Ultimately, the significance of laboratory testing extends beyond individual patient care to broader public health goals and the prevention of sexually transmitted infections.

Published: November 2023

Shewhart X chart is widely used in statistical process control for monitoring variable data and has shown good performance in detecting large mean shift but less sensitive in detecting moderate to small process shift. X chart with variable sample size and sampling interval (VSSI X chart) is proposed to enhance the ability of detecting moderate to small process shift. The performance of VSSI X chart is compared with those of Shewhart X chart, VSS X chart (Variable Sample Size X chart) and VSI X chart (Variable Sampling Interval X chart). Performance of these control charts is presented in the form of ATS (Average Time to Signal) which is obtained from computer simulation and markov chain approach. The VSSI X chart shows better performance in detecting moderate mean shift. The simulation is then continued for VSSI X chart and VSS X chart with minimum sample size n 1=1 and n 1=2.

Abstract in Bahasa Indonesia :

Peta kendali X Shewhart telah umum digunakan dalam pengendalian proses statistis untuk data variabel dan terbukti berfungsi dengan baik untuk mendeteksi pergeseran rerata yang besar, namun kurang cepat dalam mendeteksi pergeseran rerata yang sedang hingga kecil. Untuk mengatasi kelemahan ini, diusulkan penggunaan peta kendali X dengan ukuran sampel dan interval pengambilan sampel yang bervariasi (peta kendali VSSI). Kinerja peta kendali X VSSI dibandingkan dengan kinerja peta kendali Shewhart, peta kendali X VSS (peta kendali X dengan ukuran sampel yang bervariasi), dan peta kendali X VSI (peta kendali X dengan interval waktu pengambilan sampel yang bervariasi). Kinerja peta kendali dinyatakan dalam nilai ATS (Average Time to Signal) yang didapatkan dari hasil simulasi program komputer maupun perhitungan Rantai Markov. Peta kendali X VSSI terbukti mempunyai kinerja yang lebih baik dalam mendeteksi pergeseran rerata yang sedang. Selain itu juga disimulasikan penggunaan peta kendali X VSSI dan peta kendali X VSS dengan ukuran sampel minimum n1=1 dan n1=2.

This paper discusses a jobs scheduling on a single machine to minimize variance of job completion time. The objective is especially important in situations where it is desirable to provide customers or jobs with approximately the same treatment. In this case, data are collected from P.T. 'XYZ'. The focus of discussion is LB/KB Departement (Leather Board/Carton Board) with carton board's production line, which produces carton board. Carton board's size is 150 x 110 cm and its thickness from 0,6 mm to 2,5 mm.

In this paper a comparison analysis, the deviation of the objective value given by a heuristic (Vh) method from the objective value given by P.T. 'XYZ' (Vp), is made. The percentage of deviation Vh from Vp is 50,36 %, which shows that the performance of heuristic is better, that is variance of job completion time by heuristic method smaller than by P.T. 'XYZ'. Besides the above discussion, the weakness dan superiority of heuristic are analyzed too.

KOMPARASI SISTEM MANUFAKTUR PUSH DAN PULL MELALUI PENDEKATAN SIMULASI
Authors: Wibisono Eric
Published: November 2023

Manufacturing systems that are often classified as push and pull often invite question: "How far do the differences between those two systems exist?" Many researches have been carried out but succinct answer to the above question is always difficult to reach. The difficulty roots from the variety of definition of the push and pull systems itself and also from the variety of complexity of a manufacturing system.

This paper attempts to study the differences in performance between push and pull systems in a relatively simple model that consists of 4 serial processors with buffers located between these processors. Variations being modelled is on the setting of the system's load (high and low) and the buffer size with performance being measured include machine utilization, number of outputs and mean flow time of jobs. The approach used is simulation using ProModel software as the tool. From the experiments it can be derived that buffer size turns out to be a very critical factor in system performance. Moreover, it is also proved that when the buffer size is large, push and pull systems do not differ significantly.

Abstract in Bahasa Indonesia :

Sistem manufaktur yang umumnya dikategorikan menjadi sistem push dan pull sering mengundang pertanyaan: "Seberapa jauh perbedaan dari kedua sistem tersebut ada?" Banyak penelitian telah dilakukan namun jawaban yang lugas atas pertanyaan tersebut sulit diperoleh. Kesulitan ini umumnya berakar dari beragamnya definisi sistem push dan pull itu sendiri serta variasi dari kompleksitas suatu sistem manufaktur.

Makalah ini mencoba melihat perbedaan antara kinerja sistem push dan pull dalam suatu model sederhana yang terdiri dari 4 prosesor serial dengan buffer yang diletakkan di antara masing-masing prosesor tersebut. Variasi yang dilakukan adalah pada setting beban kerja sistem (padat dan ringan) dan ukuran buffer dengan kinerja yang diukur adalah utilisasi mesin, jumlah output dan rata-rata waktu tinggal job. Pendekatan yang dipakai adalah simulasi dengan alat bantu software ProModel. Dari eksperimen yang dilakukan didapatkan hasil bahwa ukuran buffer sangat berpengaruh terhadap kinerja sistem. Secara khusus juga dibuktikan bahwa pada ukuran buffer besar, ternyata antara sistem push dan pull tidak memiliki perbedaan yang signifikan.

Ammonia (NH3) in its aqueous solution form is used in various day‐to‐day applications such as laboratory reagents, fertilizers, and household cleaning due to its solubility in water. Hence, it is extremely important to have a large‐scale sensing system to avoid unintended health hazards. In this article, a printed washable TiO2nanoparticle (NP) layer‐based sensing solution to detect evaporated ammonia from its aqueous solution has been demonstrated in this regard. The response has a range of 1 to 25% w/v and is found to be considerably linear in the low concentration level of the ammonia solution. The sensitivity is found to be 0.47/% in the linear region. The sensor illustrates considerably easy fabrication, reusability, and gas adsorption on the sensing layer. Printed electrodes are employed on a flexible polyethylene terephthalate substrate with a washable sensing layer. It is observed that the longevity of the electrodes is considerably high. A maximum 7.5% variation in the response is observed for the reused sensor after washing. Further, it is found that the electrodes are stable enough to be used up to 4 months in ambient conditions. The sensor can be useful to monitor the leakage of NH3solution in industrial complexes and also in households.

Realizing efficient electrocatalysts is a stepping stone toward achieving high‐performance alkaline water/seawater electrolysis, but remains a crucial challenge. Herein, heterogeneous Mo2N/Ni3Mo3N electrocatalysts on nickel foam (denoted MN‐NMN/NF) that is stable and active for the hydrogen evolution reaction (HER) in both alkaline water/seawater are demonstrated. The optimized MN‐NMN09/NF achieves an ultralow HER overpotential of 11 mV@10 mA cm−2 in 1.0 m KOH electrolyte, which is not only superior to the benchmark Pt/C catalysts but also the best reported ever among NiMo‐based electrocatalysts in an alkaline environment. Successively, the optimized MN‐NMN09/NF electrocatalyst can drive HER current densities of 10 and 500 mA cm−2 using low overpotentials of 9.37 and 123 mV in 1.0 m KOH seawater electrolyte, which remains durable after 120 h long‐term electrolysis at a constant current density of 500 mA cm−2. In situ Raman analysis reveals that the enhanced performance is attributed to the accelerated H2O adsorption and OH dissociation processes on the MN‐NMN surfaces. Theoretical analysis further confirms that rapid H2O adsorption‐dissociation kinetics and H adsorption‐conversion kinetics on the Ni3Mo3N/NiOOH and Ni3Mo3N/MoOx surfaces result in boosted HER capability. This work depicts a significant potential for designing stable and efficient hydrogen production electrocatalysts for both alkaline water and seawater electrolysis.

Published: November 2023

Development of low‐cost electrocatalysts for water splitting is crucial to economical hydrogen production. Here, a highly efficient electrocatalyst composed of MoNi4‐embedded amorphous MoO2 nanosheets grown on less‐tortuosity hierarchically porous carbonized wood (MoNi4/MoO2@CW) is reported. The generation of abundant MoNi4/MoO2 heterointerfaces and defects‐rich MoO2 significantly promote the adsorption and activation of reactant molecules on the MoNi4/MoO2@CW. The obtained MoNi4/MoO2@CW catalyst exhibits ultralow overpotentials of 22 and 205 mV for hydrogen evolution reaction and oxygen evolution reaction at a current density of 10 mA cm−2, respectively. The catalyst can be used for dual‐function electrodes and assembling two‐electrode electrolyzer illustrates 10 mA cm−2 at 1.47 V and superior durability over 24 h for overall water electrolysis. Moreover, it also possesses a high mass activity of 142 Ag−1 MoNi4 at 200 mV, surpassing the Pt/C catalyst (132 Ag−1). The outstanding performance of the MoNi4/MoO2@CW is attributed to the decrease in energy barrier for water dissociation, optimal adsorption/desorption of H/O‐intermediates, and fast mass transport through the porous structure, as confirmed by experimental results and density functional theory‐based calculations. The MoNi4/MoO2@CW electrocatalyst has excellent potential for practical water splitting.

Printing metallic nanoscale features remains challenging, but particularly important for making electronic devices. In existing techniques, complex operation, and material parameters significantly limit printing resolution, materials development, and real‐time control. Alternatively, aerosols and ions are synergized to print nanoscale metals, but the ions turn out to be instable, thereby making the printing lose the ability in controlling feature sizes. Herein electrically biased parallel planes are utilized to configure electric fields for programmable and parallel printing of aerosol nanoparticles into high‐purity (>98.5 wt.%) nanoscale features in arrays over large areas (≈mm2). By applying different potentials to three horizontal parallel planes, with the middle plane containing periodic circular perforations, the fields are configured into repeating “funnels” with sizes controllable at both ends. Charged nanoparticles are then subjected to a gas flow orthogonal to the field assembling them to 3D nanoarchitectures. The “funnels” size is predictable and used to control the feature sizes. The printed nanopillars are modulated from 67 to 743 nm in diameters with aspect ratios up to 25 and show excellent mechanical and electrical properties. The programmable and parallel nanoprinting of metallic nanoscale features offers an enabling technology for accelerating the development of next‐generation high‐frequency ultra‐large scale integrated electronic devices.

Highly sensitive electronic skin (e‐skin) sensors with considerable operating range offer great possibilities for health care, human–‐machine interfaces, and intelligent robotics. Although subtle microstructures have been used in recent years to improve the sensitivity and sensing range of e‐skin sensors, the trade‐off between these features remains a big challenge to overcome. Here, an asymmetric interlocked gradient elastic modulus (AIGM) structure is designed for the first time to provide sufficient deformation space to the traditional interlocked structure while ensuring high sensitivity, and the gradient elastic modulus further extends the sensing range of the AIGM structure‐based sensors, which exhibit a maximum sensitivity of as high as 9.89 kPa−1 with an ultrawide working range that extends to above 530 kPa at the same time. As a demo, this sensor is integrated into an intelligent adjustable mouse platform for physiological signal monitoring, pressure feedback, and modulus adjustment, providing a viable alternative for hand disease prevention.

2D nanomaterials are proposed as promising photothermal materials for interfacial photothermal water evaporation. However, low evaporation efficiency, the use of hazardous hydrofluoric solution, and poor stability severely limit their practical applications. Here, a mixed solvent exfoliation surface deposition (MSESD) strategy for the preparation of NiPS3 nanosheets and NiPS3/polyvinyl alcohol (PVA) converter is successfully developed. The converter is obtained by drop‐casting the NiPS3/PVA nanosheets onto a sponge. The PVA is mainly deposited on the edge of NiPS3 nanosheets, which not only improves the stability of NiPS3 nanosheets, but also adheres to the sponge to prepare a 3D photothermal converter, which shows an evaporation rate of 1.48 kg m−2 h−1 and the average photothermal conversion efficiency (PTCE) of 93.5% under a light intensity of 1 kW m−2. The photothermal conversion mechanism reveals that the energy of absorbed photons in NiPS3 nanosheets can be effectively converted into heat through non‐radiative photon transitions as well as multiple optical interactions. To the best of the knowledge, this is the first report on the application of 2D metal‐phosphorus‐chalcogen (MPChx) for solar desalination, which provides new insights and guidance for the development of high‐performance 2D photothermal materials.
