“…The continued action of the enzymes and cells eventually resulted in erosion marks. In a recent study by Faiza et al (2021), the surface of composites showed similar cracks and erosion after treatment with the plant-derived proteases papain and bromelain. At the same time, the AFM results showed that the surface of PP particles incubated with bacteria showed obvious depression (Figure S2b), which were not obserced in the control group (Figure S2a), consistent with the SEM results.…”

Polypropylene (PP) is one of the most widely used plastics around the world. However, PP is recalcitrant to degradation under natural conditions, and its accumulation is increasingly threatening the environment. The stain LICME-ZWZR-10 was isolated from a landfill using PP as its sole carbon source. It was found to share 99.50% genetic similarity with Psychrobacillus sp. AK 1817. Upon incubation with Psychrobacillus sp. LICME-ZWZR-10, PP particles developed a rough surface with depressions and cracks, which were discerned through scanning electron microscopy (SEM). At a moderate temperature of 20 °C, this strain successfully degraded PP particles with an average diameter of 850 μm, leading to a 9±0.40% reduction in particle weight over a span of 30 days. Fourier transform infrared spectroscopy (FTIR) released the emergence of carbonyl and ether-based functional groups on PP. Furthermore, genomic analysis unveiled the presence of a laccase-encoding gene in Psychrobacillus sp. LICME-ZWZR-10, suggesting its potential involvement in the biodegradation of PP.

“…Bromelain is a plant protease obtained from the pineapple stem, broadly used in the food industry and able to catalyze the hydrolysis of proteins into amino acids 73 . Its capacity to promote collagen hydrolysis has been verified experimentally 74 , 75 . Similarly, papain is obtained from papaya and is a cysteine protease known for its specificity, commonly used in atraumatic dental procedures as a chemo-mechanical method to remove caries-affected substrate 73 .…”

Strategies aiming to improve the longevity of resin–dentin adhesive interface developed so far have only been able to retard the problem. Different approaches are thus needed. The objective of this review was to determine whether the use of collagen-depletion strategies after acid-etching procedures may improve the bond strength of resin-based materials to dentin. A systematic review was planned following 2021 PRISMA statement guidelines, with a search strategy performed in five electronic databases: PubMed/Medline, Scopus, EMBASE, SciELO and IADR Abstract Archive (last search: 17/01/2022). Inclusion criteria encompassed studies which evaluated a collagen-depletion strategy in acid-etched human dentin and tensile/shear bond strength tests. Risk of bias assessment was carried out by two reviewers, working independently on an adapted five-domain risk of bias (RoB) checklist for laboratory studies. Results were synthesized qualitatively, as a meta-analysis was not possible due to limited number of studies and their RoB. A total of eight studies were eligible for inclusion in the systematic review after inclusion/exclusion criteria application. Out of these, two evaluated the effect of using NaOCl followed by an antioxidant, and the remaining six evaluated different enzymatic treatments (bromelain, chondroitinase ABC, papain, and trypsin). None of the studies reported a decrease of bond strength when a collagen-depletion strategy was used, in comparison to traditional hybrid layers (control). All enzymatic treatment studies which respected the inclusion criteria improved the bond strength to dentin. Some specific collagen-depletion strategies seem to play a favorable role in improving immediate bond strengths to dentin. Further research with sound methodology is required to consolidate these findings, since limitations in RoB and a low number of studies were found. The assessment of further proteolytic agents and long-term outcomes is also required.

“…Polymers have a wide range of applications for its excellent electrical, mechanical, thermal and optical properties. 99,100,101,102,103,104 CPs are able to utilize the entire material into the charging process while the only surfaces are involved in the charging process in case of other ordinary electrode materials. During the redox reaction in CPs, electrons from the electrolyte transport into and out of the polymeric chains.…”

Energy systems are progressive and revolutionary for their alternative resources, technical developments, demands, effectiveness and environmental effects. The recently published research's goal is to assess and evaluate the systems that are already in operation and those that will be in the future. Energy can be stored as electrical energy such as supercapacitors (SCs) and superconducting magnetic energy storage (SMES) etc., mechanical energy such as pumped hydro energy storage (PHES), compressed air energy storage (CAES) and flywheel energy storage (FES) etc., chemical energy, electrochemical energy such as batteries and fuel cells etc., and thermal energy. Performance of these energy storage systems (ESSs) have been evaluated in terms of energy density, power density, power ratings, capacitance, discharge-time, energy-efficiency, life-time and cycling-times, and costs. Supercapacitors provide highest power density (>10,0000 W/l), while hydrogen fuel cells provide highest energy density (500-3000Wh/l) among other EESs. Batteries also provide high energy density(200-500Wh/l). The energy efficiency is found highest in SMES system (95-98%), and lowest in TES system (30-50%). Moreover, batteries and supercapacitors have the cycle efficiency above 90%. PHES and CAES seem to be the most cost-effective energy storage systems reviewed in this analysis in terms of $/kWh. In addition, power-based capital cost of supercapacitors is lower (100-300$/kW) compared to energy-based capital cost of supercapacitors (300-2000$/kWh). In comparison with power-based capital costs, the energy-based capital cost of batteries is lower, which is 150-400$/kWh for Lead-acid battery, and <300$/kWh for Li-ion battery. This essay may help researchers in choosing the advanced energy storage technologies for relevant purposes.
