Innovative super-hydrophilic/superoleophobic eco-friendly sponge composite is fabricated by integrating chemically-modified cellulose with lignin derived from bio-waste wheat-straw. Such combination is implemented by modifying cellulose with thiadiazole-amide and integrating it with lignin using microwave/ultrasonic-powered in-liquid plasma. Physicochemical characteristics of sponge-composite (WL-TDAC) are studied using FTIR, N-physisorption, DLS, SEM, chemical-computational analysis, and surface wettability.

Samarium-doped ZnO nanorods (Sm-doped ZnO) are stabilized onto the laminar structure of cuttlefish bone (CB) matrix and adorned by either Ag NPs or cobalt phthalocyanine (CoPc) species. Physicochemical characteristics of such nanocomposites are scrutinised.

Physicochemical properties of ZnAl-LDH-VO are characterized in detail. Decavanadate anions are intimately interacted with ZnAl-LDH nanosheets, generating highly ordered architecture of well-dimensioned stacking blocks of brucite-like nanolayers (∼8 nm).

As deferasirox (DFX) is an approved Fe chelator drug, its inability to cross blood brain barrier (BBB) remains a definite obstacle against its use as Fe chelator in the brain. Lately, attention to nanoparticles usage in researches has been widely grown since their role in improving drug therapeutic effects and scavenging free radicals make them good candidates as chelating and antioxidant agents.

The operating interaction profile and the photoactive behavior of this nanocomposite were assessed via XRD, FTIR, Raman, TEM, FE-SEM, DLS, DRS and PL techniques. Locality of Sm-doped ZnO and its attaching modes to the cuttlefish bone lamella were highly dominated by embedding Ag NPs that encouraged Zn Lewis acid sites to electrostatically interact with aragonite carbonates in the channeled porous CB system.

Physicochemical features of such nanocomposites were analyzed by XRD, FT-IR, Raman spectroscopy, UV-vis spectrophotometer, N2-BET, DLS, zeta-potential measurements, SEM, and HR-TEM. Limited interactions were observed in GAL@Ce-HAp with prevailed existence of dispersed negatively charged rod-like particles conjugated with ceria nanodots.

This study aims to manipulate an antischistosomal nanocomposite based on exfoliated clay immobilized heteropolyoxotungstate. The nanocomposite's physicochemical characteristics were examined using XRD, Raman spectroscopy, FTIR, DLS, SEM, HR-TEM and AFM. Nano-sized spheroidal negatively charged Keggin-type heteropolyoxotungstate particles were developed along and between the exfoliated clay layers.
