Integrating agro‐residue valorization and clean hydrogen production: coconut fiber‐based catalysts for NaBH4 hydrolysis

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...

A fine grained heuristic to capture web navigation patterns [PDF]

, 2000
In previous work we have proposed a statistical model to capture the user behaviour when browsing the web. The user navigation information obtained from web logs is modelled as a hypertext probabilistic grammar (HPG) which is within the class of regular

Positive Doping Test Linked to Crumb Rubber From Artificial Football Pitch: Case Report

Drug Testing and Analysis, EarlyView.
1,3‐DMBA was detected in urine samples of eight athletes following a doping control, resulting in one AAF and levels below WADA's MRL in seven teammates. Investigation revealed contamination from rubber infill used on the indoor artificial turf, with analysis confirming 1,3‐DMBA in the turf's crumb rubber originating from recycled tires.

Excitability in semiconductor microring lasers: Experimental and theoretical pulse characterization

, 2010
We characterize the operation of semiconductor microring lasers in an excitable regime. Our experiments reveal a statistical distribution of the characteristics of noise-triggered optical pulses that is not observed in other excitable systems.

Genetically Engineered Nanobody–Recombinant Antibody Colloidal Gold Strip for Ultrasensitive Atrazine Detection in Fruits and Vegetables

Food Safety and Health, EarlyView.
A sensitive colloidal gold immunochromatographic assay for atrazine was successfully established using genetically engineered nanobody‐recombinant antibody, which overcame the shortcomings of traditional antigen‐antibody. ABSTRACT Colloidal gold immunochromatography (CG‐ICA) is distinguished by its cost‐effectiveness and rapid detection capabilities ...
