In this work, novel carriers- nanoemulsomes (NE) of ganciclovir (GCV) and a fluorescent marker sodium fluorescein (SF) were developed and evaluated for posterior ocular delivery topical route. GCV loaded emulsomes (GCV NE) were optimized by a factorial design and various characterization parameters were performed on the optimized batch. The optimized batch had particle size of 131.04 ± 1.87 nm, % entrapment efficiency of 36.42 ± 3.09% and its TEM image showed discrete spherical structures below 200 nm. Ocular irritation potential of excipients and formulation were evaluated by cell line based tests on SIRC cell line, results confirmed the safety of excipients for ocular use. Precorneal retention and pharmacokinetic studies of GCV NE were performed in rabbit eyes which showed significant retention of GCV NE in the cul-de-sac. The ocular distribution study of SF-loaded nanoemulsomes (SF NE) were performed in mice eyes by confocal microscopy, images showed fluorescence in the various internal layers of retina, suggesting efficacy of emulsomes in delivering agents to the back of eye topical administration.

The sustainable synthesis of bio-based monomers from renewable biomass intermediates is a central goal in green chemistry and biorefinery innovation. This study introduces a synergistic catalytic-enzymatic strategy for the efficient and eco-friendly oxidation of 5-hydroxymethylfurfural (5-HMF) into 2,5-furandicarboxylic acid (FDCA), a key monomer for next-generation biodegradable plastics. The catalytic phase employed non-noble metal catalysts, MnO and Co-Mn supported on activated carbon (Co-Mn/AC), under mild batch reaction conditions at 90 °C.

We present UniFORM, a non-parametric, Python-based pipeline for normalizing multiplex tissue imaging (MTI) data at both the feature and pixel levels. UniFORM employs an automated rigid landmark registration method tailored to the distributional characteristics of MTI, with UniFORM operating without prior distributional assumptions and handling both unimodal and bimodal patterns. By aligning the biologically invariant negative populations, UniFORM removes technical variation while preserving tissue-specific expression patterns in positive populations.

Exopolysaccharides are biopolymers with wide-ranging industrial applications. To substitute fossil-based by bio-based, biodegradable polymers, exopolysaccharide production needs to become much more efficient. Pullulan, produced by , is popular for its unique properties like film-formation, adhesiveness, biodegradability, etc.

(GR) is primarily produced in Laiyang and Chifeng. It is a functional food with therapeutic and health-promoting effects due to its antioxidant and anti-inflammatory properties. However, the current standards only stipulate authentication criteria, without establishing a comprehensive evaluation framework to systematically enhance the quality control of GR.

A novel silica-based sorbent, silica-carbazole-formazan (Si-Carb-Formazan), was synthesized through in situ functionalization with a newly prepared carbazole formazan derivative to remove Cu-(II) ions from aqueous solutions efficiently. The sorbent was characterized using techniques such as FTIR, SEM, TGA, and XPS, which revealed a porous structure with a high surface area and excellent thermal stability. Batch adsorption experiments analyzed the influence of various factors on the sorbent's performance, demonstrating its high efficiency.
