Authors: Nath Debjani , Khanam Nasima , Ghosh Ashutosh 
Published: March 2021

Aims: Cerebral ischemia is a condition that occurs when the blood vessels in the brain are occluded. Subsequent pathophysiological changes include critical structural and functional damage to the blood-brain barrier. Since remedies for restoring the blood-brain barrier are lacking, alternative methods are important. This study aims to discuss the potential role of phytochemicals in ameliorating blood-brain barrier inflammation and hyperpermeability.
Methodology: This literature review is based on information available in open source databases for the scientific community.
Results: Phytochemicals offer a large resource for neuroprotective cure. Different categories of phytochemical compounds have provided safer and accessible means of medication. A number of phytochemicals have demonstrated antioxidant and anti-inflammatory properties. The respective mechanisms of action have also been discovered for many. Phytochemicals generally inhibit the classic inflammatory signalling molecules, in addition to other pathways. Phytochemicals also strengthen the tight junctional complexes in the blood-brain barrier. Thus phytochemicals substantially improve the affected blood-brain barrier after cerebral ischemia.
Conclusion: Phytochemicals possess useful properties directed towards the healing of the blood-brain barrier in cerebral ischemia and further research may elevate phytochemicals as approved therapeutics.

Published: March 2021

Background: Folic acid deficiency is one of the most common vitamin deficiencies among women of childbearing-age. Folic acid is a water-soluble B-complex vitamin. Although the deficiency is easily corrected by administration of folic acid, but still the prevalence of folic acid deficiency is high. It can lead to neural tube defects (NTDs) in fetus, which are a major cause of severe disability and mortality among infant population, occurring in over one quarter of a million new-borns per year, worldwide. NTDs occur in the very early phase of pregnancy when the mother herself does not know that she is pregnant. This study has assessed awareness of women of childbearing age on folic acid i.e., timing of folic acid supplementation, different sources, symptoms of its deficiency, toxicity and its effect on fetus. Study was conducted in Ha’il region and its suburbs, Kingdom of Saudi Arabia in the period between October 2020 and February 2021.
Methodology: An analytical cross-sectional community-based study was carried out among 842 women aged between18 and 45 years using a close-ended questionnaire.
Results: In total, Folic Acid was taken by just 23.87% of participants. Only 33% knew that Folic Acid deficiency causes neural tube defects in fetus. Further it was revealed that postgraduates had a significantly better knowledge on Folic Acid 0.000) than others. Similarly, those who belonged to household where total monthly income was 5000 Saudi Riyals or more had better awareness on Folic Acid than participants who belonged to low socioeconomic status ( 0.05).
Conclusion: It’s concluded that in Ha’il and its suburb area, women of childbearing age do not possess adequate knowledge on Folic Acid. Neural tube defects in fetus due to folic acid deficiency were not known by a large majority of respondents. However, awareness has a strong association with educational level and socioeconomic status. Hence it is recommended that female literacy and female employment should be promoted, encouraged and supported in Kingdom in order to improve our health indicators.

Published: March 2021

AbstractElectrochemical nitrogen reduction reaction (eNRR) is recognized as a promising approach for ammonia synthesis, which is, however, impeded by the inert nitrogen and the unavoidable competing hydrogen evolution reaction (HER). Here, a Mo‐PTA@CNT electrocatalyst in which Mo species are anchored on the fourfold hollow sites of phosphotungstic acid (PTA) and closely embedded in multi‐walled carbon nanotubes (CNT) for immobilization is designed and synthesized. Interestingly, the catalyst presents a high ammonia yield rate of 51 ± 1 µg h−1 mgcat.−1 and an excellent Faradaic efficiency of 83 ± 1% at −0.1 V versus RHE under ambient conditions. The concentrations of NH4+ are also quantitatively calculated by 1H NMR spectra and ion chromatography. Isotopic labeling identifies that the N atom of the formed NH3 originates from N2. The controlled experiments confirm a strong interaction between Mo‐PTA and N2 with an adsorption energy of 50.46 kJ mol−1 and activation energy of 21.36 kJ mol−1. More importantly, due to CNT's gas storage and hydrophobicity properties, there is a fourfold increase in N2 content. The concentration of H2O is reduced by more than half at the interface of the electrode. Thus, the activity of eNRR can be significantly improved with ultrahigh electron selectivity.

Published: March 2021

AbstractCell encapsulation within hydrogel droplets is transforming what is feasible in multiple fields of biomedical science such as tissue engineering and regenerative medicine, in vitro modeling, and cell‐based therapies. Recent advances have allowed researchers to miniaturize material encapsulation complexes down to single‐cell scales, where each complex, termed a single‐cell microgel, contains only one cell surrounded by a hydrogel matrix while remaining <100 μm in size. With this achievement, studies requiring single‐cell resolution are now possible, similar to those done using liquid droplet encapsulation. Of particular note, applications involving long‐term in vitro cultures, modular bioinks, high‐throughput screenings, and formation of 3D cellular microenvironments can be tuned independently to suit the needs of individual cells and experimental goals. In this progress report, an overview of established materials and techniques used to fabricate single‐cell microgels, as well as insight into potential alternatives is provided. This focused review is concluded by discussing applications that have already benefited from single‐cell microgel technologies, as well as prospective applications on the cusp of achieving important new capabilities.

Published: March 2021

AbstractRecently, organic hybrid halide perovskites have been found to show thermochromism with good optical performance, which can be applied in smart windows to reduce building energy consumption. However, these perovskites have shortcomings regarding their thermochromic performance, namely long transition time, high transition temperature, and large transition hysteresis width. In this study, a hydrated MAPbI3−xClx thermochromic perovskite smart window (H‐MAPbI3−xClx TPSW) is proposed, which undergoes a reversible transition between a transparent state and a dark reddish‐brown tinted state with a high solar modulation ability of 23.7%. Most importantly, the H‐MAPbI3−xClx TPSW possesses a tunable low transition temperature of 29.4 to 51.4 °C, a controllable and narrow transition hysteresis width (7.7–13.2 °C) and a short transition time (1–4 min). Additionally, a mathematical model is developed to predict the transition temperature of the H‐MAPbI3−xClx TPSW. A field test is also conducted, demonstrating that the H‐MAPbI3−xClx TPSW fitted to a model house can reduce the indoor air temperature by 3.5 °C compared to using a quartz glass window. Overall, the H‐MAPbI3−xClx TPSW can yield excellent optical properties, while simultaneously providing remarkable transition properties, making it potentially useful for a wide range of applications in energy‐efficient buildings.

Published: March 2021

AbstractThe layered V2O5 cathode exhibits appealing features of multiple electron redox processes and versatile cation‐storage capacities. However, the huge volume respiration induces structural collapse and limits its commercial‐scale deployment. Herein, a scalable water‐bath strategy is developed to tailor the (001) spacing of the bulk V2O5 from the original 4.37 Å to its triple value (14.2 Å). The intercalated polyaniline (PANI) molecules act as pillars in the V2O5 interlayer, thus affording the abundant storage sites and enhanced cation diffusivities of Li+, Na+, or hydrated Zn2+. Upon various cations (de‐)intercalation, transmission‐mode operando X‐ray diffraction is employed to document the zero‐strain behavior of the PANI‐intercalated V2O5. This scalable intercalation‐polymerization strategy, coupled with the compatibility study of the ionic radius and the c‐lattice for the layered structure, enables the rational engineering of the intercalation‐type cathodes toward facile reaction kinetics.

AbstractAqueous solutions of some amphiphilic block copolymers undergo a sol–gel transition upon heating and are thus called thermogels. In the thermogel family, some systems also exhibit a gel–sol (suspension) transition at higher temperatures following the sol–gel transition, which is usually ignored in biomedical applications. Herein, for the first time, a case is reported employing both the sol–gel transition and the gel–sol (suspension) transition, which is found in the development of a transdermal hydrogel formulation containing 5‐aminolevulinic acid for photodynamic therapy (PDT) of skin disease. Two poly(d,l‐lactide‐co‐glycolide)‐b‐poly(ethylene glycol)‐b‐poly(d,l‐lactide‐co‐glycolide) triblock copolymers of different block lengths are synthesized. The transition temperatures of the formulation can be easily adjusted to meet the condition of sol–gel transition temperature (Tgel) < room temperature (Tair) < gel–sol (suspension) temperature (Tsol (suspension)) < body temperature (Tbody) via changing the blending ratio. Therefore, after applying to skin, formulation of spontaneous asymmetry with a hydrogel outside and a sol (suspension) inside can avoid free flowing and achieve rapid release to ensure an efficient PDT. This study demonstrates such a concept via characterizations of the “block blend” biomaterials and drug release profiles, and also via cell experiments, in vitro permeation, and in vivo transdermal delivery studies.

AbstractThe study of purely organic room‐temperature phosphorescence (RTP) has drawn increasing attention because of its considerable theoretical research and practical application value. Currently, organic RTP materials with both high efficiency (ΦP > 20%) and a long lifetime (τP > 10 s) in air are still scarce due to the lack of related design guidance. Here, a new strategy to increase the phosphorescence performance of organic materials by integrating the RTP host and RTP guest in one doping system to form a triplet exciplex, is reported. With these materials, the high‐contrast labeling of tumors in living mice and encrypted patterns in thermal printing are both successfully realized by taking advantage of both the long afterglow time (up to 25 min in aqueous media) and high phosphorescence efficiency (43%).

Published: March 2021

AbstractThe presence of molecular monolayers on semiconductor surfaces can improve the stability of semiconductor interfaces by inhibiting the growth of native oxides and defects which affect the materials’ electronic properties. The development of catalytically active passivated interfaces on semiconductor materials presents a useful material design for value‐added product conversion. Herein, an iron‐based catalyst covalently attached to silicon (Si) is reported for the investigation of activity and electrochemical decomposition pathways of diiron hydrogenase enzyme mimics. The employed catalyst, Fe2(CO)6(µ‐S‐C6H4‐p‐OH)2 ([FeFe]), mimics the active sites of these enzymes. Surface modification using this catalyst passivates the interface, hindering the formation of native SiO2 for more than 300 h. [FeFe] modification improves the overpotential required to produce 10 mA cm–2 by 100 mV, with a hydrogen evolution rate of 2.31 × 10–5 mol h–1 cm–2 (−0.78 V versus RHE). However, structural rearrangement transpires within 1 h of electrolysis, where Fe‐S bond dissociates at the catalytic center, resulting in an aromatic linkage modified Si interface. While semiconductor−catalyst interfaces have often been reported in the literature, their decomposition pathways have received limited discussion. Herein, this Si−[FeFe] interface is used as a tool for understanding the activity and decomposition mechanisms of the attached molecular catalyst.
