Proteogenomics is a recently developed omics application, adding enhancing the sensitivity of proteomics, and thus making possible the detection of proteome markers in very tiny amounts of samples. Even if the filed developed only in the last 10 year...

The main phenolic compounds in the Hippophae rhamnoides fruit with potential therapeutic activities are quercetin-3-O-rhamnoside, quercetin-3-O-galactoside, myricetin, rutin, luteolin, kaempferol, vitexin, gallic acid, chlorogenic acid, caffeic acid,...

This paper presents a method for monitoring food freshness and quality through the early detection of biogenic amines, which are indicators of food spoilage/degradation. The urge to monitor food quality has led to a growing interest in the detection...

This study investigated the combined alkaline and enzymatic hydrolysis of eggshell membranes for obtaining ingredients for food and cosmetic applications. 1.25 N NaOH and Alcalase 2.4 L protease were used for eggshell membrane hydrolysis. The charact...

The diagnosis, thermography, aerial photogrammetry, and conservation treatment with nanomaterials (CHAp) for some samples from Sacidava Fortress, Romania, are analyzed and the results are discussed accordingly in this paper.

One severe public health problem globally is air pollution, as exposure to air pollutants threatens the health of people everywhere in the world. Agriculture generates waste, the improper disposal of such waste producing adverse environmental effects...

Agriculture and agriculture-related industries generate many different forms of by-products and waste, whose integration into the circular economy still requires experimental studies and research. This research aimed to obtain innovative coatings con...

This study’s objective was to assess pullulan, in the form of pullulan acetate, as a matrix for senotherapeutics delivery. Polymeric nanoparticles loaded with various senotherapeutics (metformin, quercitin, kaempferol, curcumin, and luteolin) w...

Annually, considerable amounts of polluted water are produced due to industrialization based on processing in various industries. The purpose of this study refers to a process of obtaining a photocatalytic system with a structure of metal oxides in t...

The present work focused on the synthesis and characterization of scaffold type biomaterials based on calcium silicate doped with magnesium ions for bone regeneration with potential applications in tissue engineering. Starting from the idea that calc...

In recent years, there have been growing concerns about finding alternatives to fossil fuels, and biomass could be one of them. To ensure the production of biogas as one of the alternative sources, the development of anaerobic digestion technologies...

Biosurfactants are amphiphilic molecules produced by various microorganisms, with potential applications in different industries or processes. The present study aimed to investigate the potential of food (whey) and industrial (corn extract) by-produc...

The valorization potential of lignin-rich residual red liquor, derived from wood processing for cellulose manufacturing, was investigated through two distinct experimental pathways: a slow pyrolysis and a catalytic pyrolysis process. The biochar qual...

Fertilizers with nitrogen (N), phosphate (P), and potassium (K) were formulated using a custom-made rotary pan granulator. The granules were characterized by analysis of their composition, specific surface and porosity (Brunauer–Emmett–Te...

This work proposes a process for a bio-based hydrogel suitable for 3D-printing formulation. The components of the hydrogel are sodium alginate, tetrasodium pyrophosphate, and calcium sulfate. Changes in the rheology of hydrogels based on alginate cro...

Sulfite liquor is the by-product of wood chips treatment. An alternative method for recovering the carbonaceous components from sulfite liquor was investigated. A 3% CS suspension surprisingly incorporated almost all the carbon–sulfite phase in...

This work investigates the effect of a sequential extraction process, a combination of ultrasound-assisted extraction and microwave-assisted extraction, on the antioxidant activities of pectin extracted from grape pomace. Our results demonstrated the...

Inductively coupled plasma optical emission spectrometry (ICP-OES) analytical method was optimized to determine the micronutrient concentrations from the fertilizers used as inputs in organic farming. The calibration curves showed good linearity for...

The current work presents a sustainable, environmentally friendly method for lignin extraction by applying deep eutectic solvents (DES), which are biodegradable. The Solid-DES extraction (SDESE) method of recovering lignin from reeds is presented. DE...

Sodium lignosulfonate produced in the wood-pulping sulfite process is a valuable side-product of the pulp and paper industry. Its value can be greatly increased via processing to reduce its water content, and increase its purity with respect to other...
