This study presents a life-cycle analysis of greenhouse gas (GHG) emissions biodiesel (fatty acid methyl ester) and renewable diesel (RD, or hydroprocessed easters fatty acids) production from oilseed crops, distillers corn oil, used cooking tallow. Updated data for biofuel waste fat rendering were collected through industry surveys. Life-cycle GHG reductions producing RD soybean, canola, carinata oils range 40% to 69% after considering land-use change estimations, compared with petroleum...
A relative humidity (RH) sensor based on tilted fiber Bragg grating (TFBG) is proposed by utilizing polyvinyl alcohol (PVA) as the sensitive cladding film. RH increasing in PVA coating will result reduction of refractive index. Due to TFBG's sensitivity ambient index, spectral properties PVA-coated TFBG are modified under exposure different levels ranging from 20% 98% RH. The transmission power has linear behaviors for two ranges (20%-74% and 74%-98% RH), each range reaches high 2.52 14.947...

ABSTRACT Aims This study investigated the current status of nutrition literacy and related influencing factors in stroke patients, with a view to providing reference for development targeted interventions. Design Cross‐sectional study. Methods A convenience sampling method was used select 342 patients from June November 2024 as population, cross‐sectional survey conducted using General Information Questionnaire, Nutrition Literacy Scale, Herth Hope Chronic Disease Self‐Efficacy Scale Social...
Dynamic light scattering, scanning electron microscopy, and turbidity measurements have been applied in the investigation of nanoaggregate formation poly(ethylene oxide)-b-polymethacrylate (PEO-b-PMA) which PMA block is electrically neutralized with alkaline earth metal ions. They self-assemble to form micelle-like nanoaggregates comprised a “core” polyions surrounded by PEO “corona”. The properties both amphiphilic copolymer micelles polyelectrolyte complexes. significance these new types...
Abstract A series of well‐defined amphiphilic graft copolymers bearing hydrophobic poly( tert ‐butyl acrylate) backbone and hydrophilic poly[poly(ethylene glycol) methyl ether methacrylate)] (PPEGMEMA) side chains were synthesized by sequential reversible addition fragmentation chain transfer (RAFT) polymerization single‐electron‐transfer living radical (SET‐LRP) without any polymeric functional group transformation. new Br‐containing acrylate monomer,...

The effects induced by SO<sub>2</sub> on Pt/Al<sub>2</sub>O<sub>3</sub> catalysts were studied as a function of exposure time, and NO oxidation activity was investigated for different treated catalysts. mechanism poisoned regenerated is expected.
Abstract A series of well‐defined amphiphilic triblock copolymers, poly(ethylene glycol)‐ b ‐poly( tert ‐butyl acrylate)‐ ‐poly(2‐hydroxyethyl methacrylate) (PEG‐ ‐P t BA‐ ‐PHEMA), were synthesized via successive atom transfer radical polymerization (ATRP). ATRP BA was first initiated by PEG‐Br macroinitiator using CuBr/ N,N,N ′, N ″, ′″‐pentamethyldiethylenetriamine as catalytic system to give PEG‐ diblock copolymer. This copolymer then used initiate HEMA, which afforded the target...
A novel double-layered antibacterial coating was fabricated on pure titanium (Ti) via a simple three-step electrodeposition process. Scanning electronic microscopy (SEM) images show that the constructed with inner layer of TiO2 nanotubes doped silver nanoparticles (TNTs/Ag) and outer chitosan-gelatin mixture zinc oxide (CS-Gel-Ag-ZnO). In comparison, we also investigated composition, structure properties Ti coated TNTs, TNTs/Ag or + CS-Gel-Ag-ZnO, respectively. The TNTs about 100 nm wide 240...
A hollow-core photonic crystal fiber Fabry-Perot interferometric (HC-PCF-FPI) strain sensing system is proposed and demonstrated. The has an excellent multiplexing capability owing to the wide free-spectral range of HC-PCF-FPI structure. Moreover, with a simple fast Fourier transform demodulation method, could be potentially applied in structural health monitoring.
Abstract This study presents a life‐cycle analysis (LCA) of the greenhouse gas (GHG) emissions biodiesel (BD) and renewable diesel (RD) produced from soybean varieties with altered oil profiles meal composition. The evaluated include those high oleic content (78% being vs. current 25%), lipid (25% 19%) or protein (45% 35%). results suggest that high‐oleic could reduce GHG RD by 1 g CO 2 e/MJ reducing hydrogen consumption in hydro‐treating stage production. With default allocation method...
