Corrosion Performance of Steel and Zinc‐Based Materials in Diverse Unsaturated Soils: Insights From a 2‐Year Field Exposure

open access: yesMaterials and Corrosion, EarlyView.
The present study generated the corrosion performance of C‐steel, zinc, and galvanized steel in different global unsaturated soil environments for 2 years. Acceptable matching was observed between corrosion rates and identified corrosion products. To properly predict soil corrosion, the results showed that DIN 50929 should include a drainage‐capability

Gamma Irradiation‐Based Free Radical Grafting of N‐Hydroxyethyl Acrylamide onto Poly[(R)‐3‐hydroxybutyrate]

open access: yesMacromolecular Rapid Communications, EarlyView.
This work demonstrates successful gamma‐radiation‐induced grafting of N‐hydroxyethyl acrylamide onto poly[(R)‐3‐hydroxybutyrate], producing substantial changes in material properties. Grafting generated a biphasic, less crystalline structure with enhanced thermal stability, elongation (65%), toughness (378% increase), and exceptional water uptake (610 ...

Association between phase angle and all-cause mortality in adults aged 18–49 years: NHANES 1999–2004

open access: yesScientific Reports
Phase angle (PhA) is an indicator of nutritional status. The association between PhA and all-cause mortality has been confirmed in older adults, but no relevant studies have been conducted in adults aged 18–49 years.

Outpatient preoperative parenteral nutrition in malnourished surgical patients: A feasibility study (the OPPORTUNITY study)

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Preoperative parenteral nutrition (PN) improves outcomes in malnourished surgical patients. Traditionally, this requires hospital admission, increasing length of stay and costs—challenges worsened by limited hospital bed availability. Outpatient PN may offer a feasible alternative.

Validity and agreement of bioelectrical impedance equations against dual energy X‐ray absorptiometry for muscle mass assessment in patients on hemodialysis: A cross‐sectional study

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background Low muscle mass is common in patients on hemodialysis (HD), and bioelectrical impedance analysis (BIA) predictive equations have been proposed as an alternative for estimating muscle mass. This study aimed to analyze the validity and agreement of different BIA‐based prediction equations against dual energy X‐ray absorptiometry (DXA)
