Adsorption of Congo red dye onto activated carbon from periwinkle shell was carried out to see if the activated carbon from Periwinkle shell will provide a good alternative for the commercial activated carbon in the adsorption of Congo red dye from polluted water. Periwinkle shells carbonized at 400 o C and activated with 0.1M HCl at 800 o C in a furnace was used as adsorbent to remove Congo red dye from aqueous solution. The effect of the variables: contact time, temperature and initial Congo red concentration were studied through single-factor classical method. The contact time range, 30 -180min, temperature range, 30 -55 o C and concentration range, 25 -150mg/L were used to study the adsorption efficiency, kinetic and thermodynamic studies of the process . The results show that equilibrium is established after 120 minutes and that the percentage adsorption is highest at initial concentration of 25mg/L. Again, the adsorption kinetic followed pseudo-second order reaction, having rate constant, (K 2 ) = 0.3661 g/mg.min, correlation coefficient, (R 2 ) = 0.9999 and adsorption capacity, (A de ) = 2.3585 mg/g. The thermodynamic parameters obtained are: free energy (∆ ) enthalpy (∆H) = 11.52KJ/mol and entropy, (∆S) = 60.04J/mol.K. The surface area of the adsorbent was obtained as 123.42m 2 /g. These results show that activated carbon from periwinkle shell is a viable low-cost adsorbent for the removal of Congo red dye from aqueous solution.

This paper aims to provide a bibliometric analysis of publication trends on the themes of biomass and bioenergy worldwide. A wide range of studies have been performed in the field of the usage of biomass for energy production, in order to contribute to the green transition from fossil fuels to renewable energies. Over the past 20 years (from 2000 to 2019), approximately 10,000 articles have been published in the "Agricultural and Biological Sciences" field on this theme, covering all stages of production-from the harvesting of crops to the particular type of energy produced. Articles were obtained from the SCOPUS database and examined with a text mining tool in order to analyze publication trends over the last two decades. Publications per year in the bioenergy theme have grown from 91 in 2000 to 773 in 2019. In particular the analyses showed how environmental aspects have increased their importance (from 7.3% to 11.8%), along with studies related to crop conditions (from 10.4% to 18.6%). Regarding the use of energy produced, growing trends were recognized for the impact of biofuels (mentions moved from 0.14 times per article in 2000 to 0.38 in 2019) and biogases (from 0.14 to 0.42 mentions). Environmental objectives have guided the interest of researchers, encouraging studies on biomass sources and the optimal use of the energy produced. This analysis aims to describe the research evolution, providing an analysis that can be helpful to predict future scenarios and participation among stakeholders in the sector.

This research work evaluates the impact of stormwater infiltration on the removal of organics, solids, nitrogen and phosphorus in a LECA-based horizontal subsurface flow constructed wetland. Stormwater runoff for the period between January 2008 and June 2010 (30 months) was estimated for the drainage basin of the Vila Fernando wastewater treatment plant (constructed wetland system) and it was observed proportionality between the increase in surface runoff and the infiltration flow rate that reached the plant. The average stormwater infiltration rate that reached the plant was 67.4 m(3) d(-1) (77% of the influent flow rate into the plant). The 30 month monitoring campaign set up at one of the reed beds showed that stormwater infiltration led to a high variation of the hydraulic loading rate (HLR) throughout the bed, which affected its performance in the removal of organic matter, suspended solids and nitrogen. For a HLR below 20 cm d-1 the removal efficiencies for BOD5, COD and TSS doubled. The removal of nitrogen was too low and was associated with the weak development of nitrifying biofilm and the poor growth of reeds. However, it was observed a good relationship between the applied and removed loads for most of the parameters, which seems to indicate that the organic, solid, nitrogen and phosphorus loading rates influenced the respective removal rates. The use of a bed material with high specific surface area, such as LECA, can only improve the treatment capacity of horizontal subsurface flow systems if the organic and solid loading rates, as well as the HLR, can be effectively controlled.

A sustainable management of environment and agriculture is crucial to protect soil, water, and air during intensified agriculture practices as well as huge industrial and transportation activities. A promising tool to address these challenges could be the application of biochar, a carbonaceous product of biomass pyrolysis. The efficiency of biochar could be improved through physical, chemical and microbial procedures. Engineered biochar could then be applied for various applications ranging from sustainable agriculture to pollution remediation and catalytic reactions. Biochar engineering allows achieving bio-char properties which are optimum for specific applications and/or under specific conditions. This would lead to harnessing the favorable features of biochar and to enhance its efficiency while simultaneously minimizing the existing tradeoffs. This review covers the production and applications of engineered biochar by summarizing great deals of research and knowledge on the field. Unlike previous reviews, herein biochar physical and chemical properties and the factors affecting them (i.e., biomass nature and pyrolysis conditions) have been discussed in detail. Moreover, the contributions of each physical and chemical activation/modification method to improving biochar characteristics with respect to environmental applications have been specifically scrutinized. By providing the state-of-the-art knowledge about engineered biochar production, properties, and applications, this review aims to help research in this field for identification of the culprits that must be addressed in future experiments.

The heat penetration factor fh is required when calculating the pasteurization time or the sterilization time of packaged foods. This  spreadsheet simplifies the tedious calculations of the specific surface of a food container, required to find its heat penetration factor fh. 
It deals with the effects of the food packaging on the heat penetration factor fh: the material of the packaging (metal or glass); the shape of the packaging (cylindrical; brick; oval; cube; ball), and the packaging dimensions (length, height, width, etc), expressed as specific surface S (for a liquid food), or adapted squared specific surface S*^2 (for a solid food).
After outlining the theorical equations of heat penetration factor fh, 3 extensive worked examples explain how to use this spreadsheet to estimate the S, the S*^2, and the fh of both a packaged liquid food and a packaged solid food.
The spreadsheet will be of use in the Academia and Researchgate document “How to Estimate the Heat Penetration Factor fh of Packaged Foods”.

REAKSI PENDESAKAN I. TUJUAN • Memahami arti deret Volta • Memahami reaksi pendesakan / reaksi pertukaran tunggal • Melakukan percobaan reaksi pendesakan II. DASAR TEORI Setiap logam cenderung melepaskan electron atau mengalami oksidasi atau berarti memiliki sifat reduktor. Ada logam yang mudah melepas electron (reduktor kuat) seperti logam alkali dan ada yang sukar melepas electron seperti logam mulia. Kuat lemahnya reduktor suatu logam berkaitan dengan pengertian potensial reduksi (E). potensial reduksi didefinisikan sebagai potensial listrik yang timbul jika suatu ion logam mengalami reduksi, potensial reduksi semakin besar. Berdasarkan harga potensial reduksi (E°) logam-logam dapat disusun dalam deret volta : Li-K-Ba-Ca-Na-Mg-Mn-Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb-(H)-Sb-Bi-Cu-Hg-Ag-Pt-Au Urutan potensial reduksi unsur unsur dalam deret volta semakin ke kiri semakin kecil sehingga sifat pereduksi (reduktor) semakin kuat, semakin mudah dioksidasi atau semakin sukar direduksi. Logam-logam tertentu dapat mendesak logam lain dari senyawa-senyawanya. Reaksi pendesakan disebut karena logam bebas di sebelah kiri deret volta mampu mendesak atau mereduksi logam di sebelah kanannya. Salah satu contoh reaksi pendesakan adalah kawat tembaga (Cu) yang dicelupkan dalam larutan perak nitrat (AgNO 3). Cu terletak desebelah kiri Ag, sehingga ion perak dalah larutan perak nitrat dapat didesak oleh atom Cu dan akan mengendap menjadi logam perak yang akan melapisi kawat tembaga. Pada awal reaksi larutan perak nitrat tidak berwarna, selang beberapa menit larutan mulai timbul warna biru muda karena terbentuknya ion Cu 2+. Setelah reaksi berlangsung lama, ion Cu 2+ semakin banyak, sehingga warnanya semakin biru. Disaamping itu, pada permukaan kawat tembaga terbentuk endapan putih keabuan yang merupakan ion logam perak (Ag). Reaksi pendesakan logam perak tembaga tidak lain termasuk reaksi redoks. Reaksi reduksi berlangsung pada Ag dengan penurunan bilangan oksidasi dari +1 ke 0 dan reaksi oksidasi berlangsung pada Cu dengan kenaikan bilangan oksidasi dari 0 ke + 2. Persamaan reaksi redoks yang menyatakan reaksi pendesakan ini adalah sebagai berikut : Cu (s) + 2AgNO 3 (aq) → Cu(NO3)2 (aq) + 2Ag(s)↓ Lempeng tembaga larutan perak nitrat larutan perak nitrat Endapan warna Berwarna merah tidak berwarna warna biru putih keabuan Pemanfaatan dari reaksi pendesakan antara lain untuk melakukan proses galuanisasi dengan cara melapisi logam besi dengan seng tipis atau timah yang terletak di sebelah kiri deret volta. Hal ini bermanfaat untuk mencegah korosi.

Advances in microbial enzyme technology offer a significant opportunity for developing low-energy bioconversion solutions for industrial wastes as inexpensive feedstocks for useful products. In this short communication,
two agro-food industrial wastes, chicken feather powder (CFP) and okara, were converted into peptides by a Bacillus licheniformis mutant using solid-state fermentation (SSF). The optimum SSF conditions for okara to CFP ratio, inoculum size, and time were 0.7 (7:10), 15%, and 90 h, respectively, which produced 185.99 mg/g peptides, with 910.12 U/g keratinase activity and 85.03% antioxidant scavenging activity. Compared to okara, CFP with mutant strain showed 11.28% higher keratinase activity and produced higher amounts of peptides (5.51%).

Two bed media were tested (gravel and Filtralite) in shallow horizontal subsurface flow (HSSF) constructed wetlands in order to evaluate the removal of ammonia and nitrate for different types of wastewater (acetate-based and domestic wastewater) and different COD/N ratios. The use of Filtralite allowed both higher mass removal rates (1.1 g NH 4 -N m À2 d À1 and 3 g NO 3 -N m À2 d À1 ) and removal efficiencies (>62% for ammonia, 90-100% for nitrate), in less than 2 weeks, when compared to the ones observed with gravel. The COD/N ratio seems to have no significant influence on nitrate removal and the removal of both ammonia and nitrate seems to have involved not only the conventional pathways of nitrification-denitrification. The nitrogen loading rate of both ammonia (0.8-2.4 g NH 4 -N m À2 d À1 ) and nitrate (0.6-3.2 g NO 3 -N m À2 d À1 ) seem to have influenced the respective removal rates.

The presence of 4-nitrophenol (4-NP) in the wastewater industry causes toxicity and inhibition of the anaerobic degrading bacteria. The anaerobes in the multistage anaerobic reactor were loaded by 30.0 mg/gVS Graphene nanoparticles (MAR-G n) as an electron acceptor to detoxify wastewater industry. The half maximal inhibitory concentration (IC 50) was reduced from 455 ± 22.5 to 135 ± 12.7 μg Gallic acid equivalent/mL at 4-NP loading rate of 47.9 g/m 3 d. Furthermore, 4-NP was decreased by a value of 83.7 ± 4.9% in MAR-G n compared to 65.6 ± 4.8% in control MAR. The 4-aminophenol (4-AP) recovery was accounted for 44.8% in the MAR-G n at an average oxidation-reduction potential (ORP) of − 167.3 ± 21.2 mV. The remaining portions of 4-NP and 4-AP in the MAR-G n effluent were efficiently removed by baffled high rate algal pond (BHRAP), resulting in overall removal efficiency of 91.6 ± 6.3 and 92.3 ± 4.6%, respectively. The Methanosaeta (52.9%) and Methanosphaerula (10.9%) were dominant species in MAR-G n for reduction of 4-NP into 4-AP. Moreover, Chlorophyta cells (Chlorella vulgaris, Scenedesmus obliquus, Scenedesmus quadricauda and Ulothrix subtilissima were abundant in the BHRAP for complete degradation of 4-NP and 4-AP.

The mixing rule models MHV1, MHV2 and WS were used to predict ternary VLE and VLLE at sub-and supercritical conditions of the systems water+methanol+carbon dioxide and water+ethanol+carbon dioxide. We used a cubic equation of state (SRK, PR) coupled with the G E-EOS mixing rules. For water+ethanol+carbon dioxide, it was possible to calculate and to locate the three-phase boundaries of VLLE. This three-phase region is very sensitive to the pressure.

This paper presents an example of the importance of evapotranspiration in constructed wetlands, with vertical subsurface flow, comparing different methods of treatment efficiency calculations and discussing the influence of evapotranspiration on removal rates. The application of reed, marked by high transpiration ability, is a cheap and effective method of landfill leachate disposal. A 2-year study examined the effectiveness of leachate treatment in constructed wetlands with reed. Two kinds of vertical subsurface flow systems: first with sand, and second with combined two layers of sewage sludge and sand has been tested. 1, 3, and 5 mm d −1 hydraulic loading rates of landfill leachate have been applied. Daily evapotranspiration was in the range from 0.98 to 2.99 mm d −1 in the first year of research and from 2.56 to 4.61 mm d −1 in the second year. The influence of evapotranspiration rate on chemical oxygen demand (COD) removal rate was examined. Two methods of removal efficiency calculation have been used: first based on inlet and outlet COD concentrations, second on mass balance determination. Research showed that the removal efficiency calculated as a comparison between initial and final concentration is significantly lower, than expected from mass balance, especially, when higher hydraulic loading rates were applied.

Distillation is the most common separation technique and is energy intensive. Distillation can consume more than 50% of a process plant’s operating energy cost.  A way to improve an existing plant’s operating cost or to reduce a new distillation system’s operating cost is to improve the efficiency and operations by correct equipment selection, process optimization and control. 

This course will guide the participates to develop key concepts and techniques to operate and troubleshoot a distillation system. These key concepts can be utilized to make design and operating decisions.  Training and development are an investment in future success - give yourself and your employees the keys to success.

Product recoveries, purities and energy utilization can be improved in most distillation systems.  This cannot be achieved without first an understanding of distillation principles and design. These principles need to be understood in advance of designing, operating, and troubleshooting a distillation column for the operator, designer, or problem solving to be effective.

The spread of COVID-19 has been exacerbated by the emergence of variants of concern (VoC). Many VoC contain mutations in the spike protein (S-protein) and are implicated in infection and response to therapeutics. Bivalent neutralizing antibodies (nAbs) targeting the S-protein receptor-binding domain (RBD) are promising therapeutics for COVID-19, but they are limited by low potency and vulnerability to RBD mutations in VoC. To address these issues, we used naive phage-displayed peptide libraries to isolate and optimize 16-residue peptides that bind to the RBD or the Nterminal domain (NTD) of the S-protein. We fused these peptides to the N-terminus of a moderate-affinity nAb to generate tetravalent peptide−IgG fusions, and we showed that both classes of peptides were able to improve affinities for the S-protein trimer by >100-fold (apparent K D < 1 pM). Critically, cell-based infection assays with a panel of six SARS-CoV-2 variants demonstrated that an RBDbinding peptide was able to enhance the neutralization potency of a high-affinity nAb >100-fold. Moreover, this peptide−IgG was able to neutralize variants that were resistant to the same nAb in the bivalent IgG format, including the dominant B.1.1.529 (Omicron) variant that is resistant to most clinically approved therapeutic nAbs. To show that this approach is general, we fused the same peptide to a clinically approved nAb drug and showed that it enabled the neutralization of a resistant variant. Taken together, these results establish minimal peptide fusions as a modular means to greatly enhance affinities, potencies, and breadth of coverage of nAbs as therapeutics for SARS-CoV-2.

The Kinetics of the Biosorption of Methylene Blue onto LagenariaSphaerica as adsorbent was studied and the plant was characterized to check it suitability to be used as adsorbent for the treatment of aqueous waste water. The LagenariaSphaerica used was sliced into small sizes, sun dried for 14 days and later oven dried at 105°C for 2 hours to archive bone dryness, it was ground and sieved to various particle sizes and Batch adsorption process was employed. For the study. The effect of process parameters such as Effect of contact time, adsorbent dose, initial concentration of methylene Blue and particle size were investigated. The highest dye uptake stood at 90.1% after 24 hours using an initial dye concentration of 100 ppm and adsorbent dosage of 0.3 g. The experimental data obtained was fitted into adsorption isotherms such as Langmuir and freundlich isotherm model. It was described using linear regression method. Pseudo-first order, pseudo- second order and intra-particle diffusion kinetic models was used to analyze the Experiment. The data best fitted in intra-particle diffusion model and Freundlich isotherm. Considering the result obtained, it can confidently be said that Lagenariasphaerica can be used as an adsorbent for the removal of dye from aqueous solution.
