Enhanced Recovery of Valuable Materials from Spent Lithium‐Ion Secondary Batteries Using Organic Acids as Leaching and Precipitating Agents

open access: yesChemistrySelect, Volume 9, Issue 36, September 25, 2024.
Cathode active materials were separated from the Al foil at 400°C, and oxalates of Mn, Co, and Ni were obtained at a ratio of 1.5:1.0:2.5 by precipitation with oxalic acid after metal leaching with lactic acid. Abstract In this study, the cathode active material was first separated from the aluminum foil through a heat treatment at 500 °C.

Ventilation Induced in an Isolated Subsurface Structure by Natural Forces: Method Development and Application

open access: yesInfrastructures, 2019
It is believed that isolated subsurface structures of an infrastructure do not ventilate through opening(s) in manhole covers. The literature has almost no information on this topic.

Wandering spleen: A common presentation of an uncommon anomaly [PDF]

open access: yes, 2009
Background: With the advent of real time ultrasonography of the abdomen, the spleen is no longer an inaccessible organ. Wandering spleen is a rare entity with only less than 500 cases reported so far.

Tuning the selectivity of CO2 conversion to CO on partially reduced Cu2O/ZnO heterogeneous interface

open access: yesInterdisciplinary Materials, Volume 3, Issue 3, Page 380-388, May 2024.
Cu2O/ZnO heterostructure with partially reduced matal/oxide heterostructure in zinc plate (CZZ) is synthesized, and the effectiveness of CZZ as a CO2RR catalyst is verified, resulting in an improved catalyst performance with a CO selectivity of up to 70.9% at −0.95 V versus reversible hydrogen electrode, while maintaining a stability of 24 h.

GIGANTEA accelerates wheat heading time through gene interactions converging on FLOWERING LOCUS T1

open access: yesThe Plant Journal, Volume 118, Issue 2, Page 519-533, April 2024.
SUMMARY Precise regulation of flowering time is critical for cereal crops to synchronize reproductive development with optimum environmental conditions, thereby maximizing grain yield. The plant‐specific gene GIGANTEA (GI) plays an important role in the control of flowering time, with additional functions on the circadian clock and plant stress ...
