Adsorption mechanisms of pigments and free fatty acids in the discoloration of shea butter and palm oil by an acid-activated Cameroonian smectite

Scientific African, 2020
Discoloration mechanism of shea butter and palm oil was studied by the adsorption of pigments and free fatty acids onto a Cameroonian clay. Adsorbent characterization was performed using ICP-AES, FTIR, SEM, N2 gas adsorption and CEC.

Fluorenone and Fluorenemalononitrile‐Tethered Conjugated Microporous Polymers for Efficient CO2 Uptake and Rhodamine B Removal

Macromolecular Rapid Communications, EarlyView.
TPET‐F2CN CMP exhibited higher CO2 uptake (2.88 mmol g−1 at 273 K) and superior Rhd B adsorption, with an equilibrium capacity of 98.12 mg g−1 and a maximum monolayer capacity of 155.6 mg g−1. ABSTRACT Herein, two conjugated microporous polymers (CMPs), TPET‐FO and TPET‐F2CN, are functionalized with carbonyl and nitrile groups.

A latent class analysis of depressive symptoms in youth from the Texas Youth Depression and Suicide Research Network (TX‐YDSRN): Clinical and socio‐ecological correlates

Journal of Child Psychology and Psychiatry, EarlyView.
Background Adolescent depression is heterogeneous, yet many studies rely on aggregate symptom scores that may obscure meaningful differences in symptom presentation. Latent class analysis (LCA) offers a person‐centered approach for identifying symptom subgroups, but few studies have examined depressive symptom classes longitudinally with attention to ...

Reducing overtreatment in gynecologic oncology: the case for less in endometrial and ovarian cancer

Frontiers in Oncology, 2016
A growing awareness of the harms of overtreatment in cancer care has reached physicians, patients, health policy makers and medical researchers. Overtreatment exposes patients to the risk of adverse events from procedures or medications that were not ...

Distant recurrence in a patient with polyp-confined stage IA serous endometrial carcinoma treated with adjuvant chemotherapy: A case report and review of literature

Gynecologic Oncology Reports, 2020
Uterine serous carcinoma is a rare, high-risk histological subtype of endometrial cancer, and use of adjuvant treatment in early stage IA disease is inconsistent, especially when the tumor is confined entirely within an endometrial polyp.

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Sustainable and Efficient Removal of Organic Dyes From Water Using a Graphene Oxide‐Conjugated PEGylated Polystyrene Resin

Journal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.
A graphene oxide‐functionalized PEGylated polystyrene (PS‐PEG@GO) resin is developed as a recoverable, reusable adsorbent for cationic dye removal from water. Combining efficient multi‐dye adsorption with simple filtration‐based recovery and stable reuse, it retains over 90% removal for CV and MB and 89.19% and 85.15% for R6G and RB after 20 cycles ...
