Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

From Tradition to Innovation: The Evolution and Future Prospects of Phosphorus Removal Technologies in Wastewater Treatment [PDF]

open access: yesE3S Web of Conferences
Phosphorus removal from wastewater is a critical environmental issue due to its role in eutrophication and negative impacts on aquatic ecosystems. This paper systematically reviews the evolution and prospects of phosphorus removal technologies, from ...

Phosphate removal in agro-industry: pilot- and full-scale operational considerations of struvite crystallization [PDF]

open access: yes, 2009
Pilot-scale struvite crystallisation tests using anaerobic effluent from potato processing industries were performed at three different plants. Two plants (P1 & P2) showed high phosphate removal efficiencies, 89 + 3% and 75 + 8%, resulting in final ...

Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

open access: yesAdvanced Engineering Materials, EarlyView.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Stability and performance of two GSBR operated in alternating anoxic/aerobic or anaerobic/aerobic conditions for nutrient removal [PDF]

open access: yes, 2012
Two granular sludge sequencing batch reactors (GSBR) with alternating anoxic/aerobic (R1) and anaerobic/aerobic (R2) conditions were operated with a 4-carbon-source synthetic influent. The physical properties of the granular sludge were very good (SVI≈20

Incorporation of Selenium into Sol–Gel‐Derived Bioactive Glass: Influence on Glass Structure, Bioactivity, and its Selective Cytotoxicity

open access: yesAdvanced Engineering Materials, EarlyView.
Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

Research on lateral flow treatment technology to enhance phosphorus removal of AAO process

open access: yesE3S Web of Conferences, 2018
Removing efficiently and recycling of phosphorus in the wastewater, was not only an effective means to prevent and cure the eutrophication of water, but also an important way to realize the recovery of phosphorus resources. In the traditional AAO process,

Phosphorus removal using nanofiltration membranes

open access: yesWater Science and Technology, 2011
A high concentration of phosphorus in wastewater may lead to excessive algae growth and de-oxygenation of the water. In this work, nanofiltration (NF) of phosphorus-rich solutions is studied in order to investigate its potential in removing and recycling phosphorus. Wastewater samples from a pulp and paper plant were first analyzed.

Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

open access: yesAdvanced Engineering Materials, EarlyView.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.

Removal of phosphorus from wastewater by magnetic lanthanum- modified magnesium iron hydroxide/biochar

open access: yesGongye shui chuli
Biochar(BC) has been widely studied for phosphorus removal from wastewater due to its rich pore structure and surface functional groups, but its poor adsorption capacity and lack of selectivity still need to be improved.
