Summary: Novel walnut shell biochar-nano zero-valent iron nanocomposites (WSBC-nZVI) were synthesized and showed higher removal efficiency for carbamazepine (CBZ) compared to walnut shell biochar and nano zero-valent iron when combined with persulfate (PS). The WSBC-nZVI membrane demonstrated excellent removal efficiency in a dead-end system. The study also investigated the effects of various operating conditions on the degradation efficiency and proposed the possible degradation mechanisms and toxicity of CBZ intermediates.

Summary: This study demonstrates the enhancement of peroxide activation efficiency and organic contaminant degradation by mechanically silicified microscale zero-valent iron (mZVI). The silicification process improves the generation of reactive intermediates, resulting in a significant increase in sulfamethazine removal rate. Continuous generation of ferrous ions in the Si-mZVI(bm)/PDS system after silicification contributes to the excellent performance of peroxide activation.

Summary: A novel composite (nZVI/HNTs) was prepared by incorporating nano zero-valent iron (nZVI) on halloysite nanotubes (HNTs) for degrading tetracycline hydrochloride (TCH) with the presence of persulfate (PS). The nZVI/HNTs + PS system exhibited satisfactory degradation efficiency (84.21%) for TCH, and stable nZVI/HNTs could be reused. The quenching tests and EPR analysis showed that SO4- was the dominant quencher instead of OH in this system. Three possible pathways of TCH degradation were identified through LC-MS determination. Additionally, the biological toxicity prediction analysis indicated that the nZVI/HNTs + PS system is an environmentally friendly treatment method for TCH pollution.

Summary: In this study, soybean biochar-supported sulfide-modified nanoscale zero-valent iron (BC@S-nZVI) was synthesized and used to activate persulfate (PS) for the degradation of 2-chlorophenol (2-CP) in aqueous solutions. The optimal mass ratios of PS to 2-CP and BC@S-nZVI to PS were determined to achieve the highest degradation efficiency of 2-CP. The degradation rate of 2-CP was influenced by pH, temperature, and the presence of certain anions, with acidic conditions and a pH of 3, as well as the addition of NO3- and CO32-, enhancing the degradation process. Both free radical and material functions were found to play important roles in the degradation, and BC@S-nZVI exhibited better stability compared to nZVI and S-nZVI.

Summary: An amino-functionalized MIL-68(Al) metal-organic framework was synthesized and its adsorption performance and reusability for arsenate were studied. The results showed that the adsorption of arsenate on the material was influenced by solution pH, adsorbent dose, arsenate concentration, and reaction time. Under optimal conditions, the predicted and experimental arsenate removal efficiencies were 99.45% and 99.87%, respectively. The study demonstrated that the amino-functionalized MIL-68(Al) can be an effective material for the treatment of arsenate-contaminated water, with high surface area and reusability.

Summary: This study aimed to evaluate the pattern of gestational weight gain in the slum areas of Hamadan in Iran. The results showed that most pregnant women did not achieve adequate weight gain in the first and second trimesters. Therefore, designing appropriate interventions to achieve optimal weight gain seems to be necessary in slums.

Summary: This study investigated the factors affecting the use of androgenic-anabolic steroids (AAS) among Iranian bodybuilders. The results showed that factors such as age, time of starting bodybuilding, attitude, physical self-concept, behavioral intention, coach and friend use AAS, alcohol consumption, and supplement use were associated with AAS use among non-competitive and competitive bodybuilders. The study indicates that a combination of intrapersonal, interpersonal, and behavioral factors influences the use of AAS among Iranian bodybuilders.

Summary: Muscle fatigue can lead to musculoskeletal disorders in the long term, but can be managed by understanding the causes. Heavy manual tasks result in increased grip fatigue and strength in the right hand, while light and moderate tasks require balance in both hands, leading to more fatigue in the left hand. Subject height, weight, age, and exposure to vibration have a significant impact on grip force. Future studies should be conducted on larger populations to determine the accurate effects of risk factors on muscle fatigue.
