Published: September 2022

Herein it is reported the implementation and start up of a Wastewater Treatment Plant (WWTP) installed in a cellulose recovery company from multilayer packings. Initially, it was verified the treatability of the water sample by an aerobic-anaerobic biological procedure. Based on the obtained results of the initial stage, it was proposed the design, construction, start up and evaluation of the WWTP. It was achieved the total recovery of the treated water (zero discharge) and an economic benefit for the company since the available amount of water was almost enough for the requirements of the company and only a small fraction was purchased to external contractors. These principles fit well with the concept of circular economy and sustainability. The proposed WWTP configuration included the following components: sieving, activated sludges, a secondary sedimentation and a third treatment with sand filters, activated carbon and disinfection of the water. It was attained the following results: 82% of removal of oils and fats, 85% of removal of settleable solids, 70% of removal of suspended solids and 75% of removal of DBO5. Nevertheless, it was necessary the monthly utilization of an inoculum in the biological reactor to avoid the presence of pathogens in the recovered cellulose. The correct operation of the tertiary process is necessary to avoid the presence of pathogens in the recovered cellulose, likewise, zero discharge is obtained by reusing the total treated water, saving approximately 90% of the cost of water per month.

Background: The Clinical Mentorship Programme (CMP) is an organized form of PHM programme, which was deployed as a pioneer public health intervention and modelled to support existing interventions and other ongoing strategies to catalyze better outcomes in the HIV Control Programme in Rivers State, Nigeria. CMP as a form of PHM is untested mainly in Nigeria. It is a structured intervention to complement the effort at bridging the gap of huge unmet needs in HIV service delivery in a low-resource setting, marked by a difficult terrain and security challenges. The rationale was to catalyze quality improvement in targeted indicators using locally tested initiatives, build the capacity of local teams, promote a culture of problem-solving attitude at the site level and strengthen team effort between the Institute of Human Virology, Nigeria, Government Agencies and beneficiary community.
Methodology: The CMP was implemented in the State HIV control Programme from about July 2019. The SCMs were chosen as medical doctors and trained to have the requisite knowledge to build staff and improve the quality of the HIV control programme.
Results: Two years after the introduction of the CMP, the capacity of teams was successfully established in a team command structure, which led to improvement in key performance programme indicators.
Conclusion: The CMP accelerated and supported the successful reduction in unmet treatment needs in the Rivers State HIV Control Programme within two years of its implementation. It is further recommended to be adapted in other public health programmes as a form of Public Health Mentorship to optimize service delivery in areas challenged by the high unmet need.

Published: September 2022

Aim: This study investigated the occurrence of antibiotic and heavy metal co - resistance in bacteria indigenous to mechanic workshops.
Study Design: The study is an experimental study.
Place: Samples were collected at mechanic workshop.
Methodology: Soil samples were collected from three mechanic workshops and tested for the presence of heavy metals. Hydrocarbon-utilizing bacteria was also isolated from the soils using Bushnell Haas medium supplemented with 1% engine oil or petrol. Isolates obtained were subjected to antibiotic resistance test and those that showed extensive drug resistance to the tested antibiotics were further tested for heavy metal resistance. Selected isolates were then identified using 16S rRNA gene sequence.
Results: The soil samples contained excessive amounts of Lead, Iron, Copper and Zinc, while the concentrations of Nickel, Cobalt, Cadmium and Chromium were within WHO permissible limit. A total of 10 hydrocarbon-degrading isolates were obtained from the soil samples, seven of which were gram negative and three were gram positive. Three of the isolates showed extensive drug resistance to 14 of the tested antibiotics. Three isolates were then subjected to heavy metal resistance test and all of them showed resistance to the tested heavy metals. They were identified and given ascension numbers as Stenotrophomonas maltophilia MW392903, Achromobacter xylosoxidans MW392904 and Pseudomonas aeruginosa MW392905.
Conclusion: It was observed that heavy metal resistance and antibiotic resistance can be selected for simultaneously as organisms adapt ways to cope with man’s activities in the environment, and while traits like hydrocarbon utilization and heavy metal resistance make the organisms promising in bioremediation, the inadvertent possession of antibiotic resistance by these environmental isolates poses a challenge to the health sector.

Published: September 2022

AbstractCompared with green and red perovskite light‐emitting diodes (PeLEDs), the development of blue PeLEDs has been lagging due to high defect density and inferior carrier transport. Herein, a novel defect‐passivation strategy is proposed to fabricate efficient sky‐blue PeLEDs by using isocyanate molecules. This strategy not only significantly reduces the nonradiative recombination loss caused by defects but also improves the injection and transport capacities of carriers by reducing the confinement effect. Benefiting from the passivation engineering and the reduction of confinement effect, the prepared sky‐blue PeLEDs present a significantly improved external quantum efficiency of 12.5% at 489 nm, which is 1.5 times higher than that of the control device. Meanwhile, the universality of isocyanate‐based passivators to improve the performance of PeLEDs is also demonstrated. The finding of this study provides a new reference for the selection of novel passivation agents to construct highly efficient blue PeLEDs.

AbstractA novel route to synthesize large area ZnO/Zn(OH)2 origami thin films at air/liquid interface is reported. ZnO materials derived from this route show the largest blue‐shifted band‐to‐band emission at 3.85 eV (3.37 eV in bulk ZnO) so far, resulting from the quantum confinement in the ultrathin ZnO/Zn(OH)2 nanosheets. Interband defect levels (IDLs) related broadband photoluminescence is observed from UV to red region by excitation wavelength dependent photoluminescence measurements. The ZnO origami structures show photocatalytic methylene blue degradation (MB‐degradation) activity even under sub‐bandgap visible light illumination from 405 nm to green region at 505 nm, measured by low power monochromatic light emitting diode light sources. From the consistent light absorption, luminescence, and MB‐degradation activity, it can be concluded that the broadband visible light MB‐degradation activity is attributed to photogenerated carriers via IDLs. The 2D ZnO‐nanosheets in the origami structure better solve the dilemma of the IDLs in bulk materials, i.e., they are beneficial for light absorption in visible range but detrimental for enhanced recombination loss of carriers, and they can be quickly extracted to the surface without substantial recombination. This finding makes the ZnO origami a promising candidate for efficient photocatalyst that harvesting the sunlight and for indoor applications.

Published: September 2022

AbstractPerovskite solar cells (PSCs) have received intensive attention and demonstrated power conversion efficiency (PCE) as high as 25.8%. Concerning Pb toxicity and the instability of organic elements, all inorganic lead‐free perovskites (ILPs) have been extensively studied to achieve comparable or greater photovoltaic performance. To develop ILPs as an alternative for solar cell (SC) applications, first‐principles calculations of ABBr3 perovskites (A = Cs, Rb, K, and Na, and B = Sn, and Ge) is performed. Structural, electronic, and optical properties are systematically studied to probe the potential for photovoltaic applications. These ILPs exhibit a direct bandgap in the range of 1.10–1.97 eV, which is highly beneficial for absorbing solar energy. Furthermore, these ILPs demonstrated significant optical absorption (over 105 cm−1) in the UV–Vis spectrum. These results will help design high‐performance lead‐free PSCs.

Published: September 2022

AbstractCancer photo‐immunotherapy (CPIT) as an ideal strategy can rapidly release hostile signals by appropriate dosage of focal laser irradiation to unmask primary tumor immunogenicity and can activate adaptive immunity to control distant metastases. However, many factors, including disordered immunometabolism, poor penetration of photothermal agents and immuno‐regulators, inadequate laser penetration into the deep tumor region, restrict the therapeutic outcomes of CPIT. Here, a second near‐infrared window (NIR‐II) photo‐immunometabolic cancer therapy (PICT) by a programmed raspberry‐structured nanoadjuvant (PRNMT) is presented that can potentiates efficient immunogenic cell death (ICD) in deep tumor tissue and alleviates immunometabolic disorder. The PRNMT is architected through self‐assembly of indoleamine 2,3‐dioxygenase 1 (IDO‐1) inhibitor modified small‐sized CuS nanoparticles (CuS5) and tumor microenvironment (TME) responsive cationized polymeric matrix. The TME can trigger the splitting and surface cationization of PRNMT into small cationized CuS5 that feature high transcytosis potential and TME immunometabolic regulation. Upon NIR‐II irradiation, CuS5 induce homogeneous ICD and release immunometabolic regulator in deep tumor tissues, which ameliorates IDO‐1 mediated immunometabolic disorder and further suppresses regulatory T cells infiltration. PRNMT mediated PICT effectively delays the primary murine mammary carcinoma 4T1 tumor growth and inhibits the lethal pulmonary metastasis in combination with programmed cell death protein 1 (PD1) blockade.
