X‐ray data reconstruction from incomplete data sampling

open access: yesJournal of Applied Crystallography, Volume 58, Issue 6, Page 2090-2104, December 2025.
A reconstruction procedure for patterns with incomplete information is reported. It is based on a modified Papoulis–Gerchberg algorithm. The modifications were introduced to guide the reconstruction procedure. The reconstruction algorithm could prove useful in specific experimental geometry setups.For specific setups, a diffraction pattern can contain ...

The Influence of Biodegradability and Inoculum‐to‐Substrate Ratio on the Anaerobic Digestion Performance and Microbial Diversity

open access: yesGCB Bioenergy, Volume 17, Issue 12, December 2025.
ABSTRACT Continuous‐flow anaerobic digestion (AD) of wheat straw (WS) is often limited by volatile fatty acid (VFA) accumulation at low inoculum‐to‐substrate ratios (ISRs). Here, biochar (8.0 g/L) recovered methane production in overloaded systems (ISR 0.5, HRT 12 days), increasing yields by 658.45 mL/g‐VS.

Structure investigation of nano-FeO(OH) modified clinoptilolite tuff for antimony removal [PDF]

open access: yes, 2017
Biomimetic sol-gel synthesis was used to prepare new FeO(OH) zeolite (clinoptilolite tuff) adsorbent effective for antimony removal. The product was compared with other on the market accessible natural or commercial adsorption materials like granulated ...

Zeolite deposits of possible economic significance on the northern Alaska Peninsula [PDF]

open access: yes, 1982
Clinoptilolite, mordenite, haulandite and laumontite have been identified in possible economic concentrations on the Alaska Peninsula. Most important are 1) a haulandite bearing water-laid tuff on Agate Island, 2) a thick sequence of terrestrial ...

Drosophila suzukii control using Kaolin, lime and rock dusts. [PDF]

open access: yes, 2018
The Spotted wing drosophila, Drosophila suzukii, is an invasive pest in Europe and North America, infesting various soft-skinned fruits. Because D. suzukii attacks ripening fruits shortly before harvest, only insecticides with short pre-harvest intervals

Caratterizzazione tecnologica di una Pb-clinoptilolite [PDF]

open access: yes, 2011
A Sardinian clinoptilolite rich-rock was submitted to a mineral separation process aimed to increase zeolite content. The material enriched in zeolite was subjected to exchange processes in Na- and Pb- solutions, to conduct the clinoptilolite in Pb ...
