Integrated Biorefineries for Food Waste and Food-Processing Side Streams Through Feedstock-Oriented Design and Sustainable Process Integration

Food waste represents a renewable carbon resource with considerable potential for the production of bioenergy, platform chemicals, biomaterials, and other high-value products within integrated biorefinery systems. However, the heterogeneous composition of food waste, together wit...

Mechanical and Thermomechanical Performance Evaluation of CFRP Sandwich Structures with Additively Manufactured Composite Cores

This study experimentally evaluates how various 3D-printed gyroid core materials influence the mechanical and thermo-mechanical performance of lightweight carbon-fiber-reinforced polymer (CFRP) sandwich structures. Three gyroid core configurations were considered: short-carbon-fi...

Unpromoted copper supported mesoporous silica nanocatalysts for the selective hydrogenation of biomass-derived levulinic acid to γ-valerolactone

Levulinic acid (LA), derived from lignocellulosic biomass, is an important platform molecule for the production of renewable fuels and value-added chemicals. Its catalytic hydrogenation to γ-valerolactone (GVL), a bio-based compound with applications as a fuel additive, solvent,...

Targeting Sirtuins in Neurodegenerative and Psychiatric Disorders: From Molecular Mechanisms to Pharmacological Modulation

Neurological and psychiatric disorders share several biological mechanisms, including mitochondrial dysfunction, oxidative stress, neuroinflammation, impaired protein homeostasis, and changes in synaptic plasticity. Sirtuins (SIRT) are nicotinamide adenine dinucleotide (NAD+)-dep...

Diagnostic and Management Challenges in Mixed-Source MDR Sepsis in a Kidney Transplant Recipient with an Infected Sacral Pressure Ulcer Treated with VAC Therapy: A Case Report

Background: Kidney transplant recipients are particularly vulnerable to severe infections because of chronic immunosuppression, impaired wound healing, repeated healthcare exposure, and the potential nephrotoxicity of antimicrobial therapy. We report a complex case of multidrug-r...

The Impact of Supreme Audit Institutions’ Independence on SDG 2 Performance: A Cross-National Empirical Analysis

Food insecurity persists globally despite growing public investment—a pattern that points to the potential role of governance and accountability mechanisms in shaping how resources are managed and allocated. While supreme audit institutions (SAIs) are widely recognized for their...

Frictionless Electromagnetic Braking for Electric and Autonomous Vehicles: Contactless Operating Principles, Brake-by-Wire Integration, and Research Challenges: A Critical Review

Eddy-current braking is increasingly considered a promising complementary technology to conventional hydraulic braking systems in next-generation automotive platforms, particularly in electric and autonomous vehicles. Unlike traditional friction-based systems, eddy-current brakin...

Evidence-Aware Multicriteria Assessment for Industrial Lighting Audits: Separating Performance from Evidence Coverage

Industrial lighting audits may combine heterogeneous measurements into performance scores without demonstrating whether the underlying evidence is sufficiently complete, representative, and traceable. This study proposes an evidence-aware multicriteria assessment framework that s...

A Bibliometric Study of the Emerging Trends in Blockchain Research

The field of blockchain technology is continuously expanding and attracting more research interest. Blockchain promises decentralization, transparency, traceability, and resistance to censorship, all of which have prompted a heightened adoption in a wide range of sectors. We anal...

Overcoming the Biomechanical Limitations of Titanium–Zirconia Dental Implants: Rationale for a Novel Ti-PEEK-Zr Tri-Layered Concept

Background: The clinical success of modern dental implants requires a balance between mechanical endurance and aesthetic integration. While titanium alloy (Ti-6Al-4V) provides a reliable load-bearing core, yttria-stabilized tetragonal zirconia (Y-TZP) is frequently preferred for...

Design–Build–Test in a First-Year Civil Engineering Laboratory: A Thin-Cardboard Truss Bridge Case Study

Abstract This case study describes the implementation of a resource-light design–build–test laboratory project embedded in a first-year civil engineering course, where many students begin with limited competence in statics and mechanics. Student teams designed and fabricated a th...

Integrated Safety and Security Risk Analysis of Lane Keeping Assistance Using TARA

Lane Keeping Assistance (LKA) systems play a critical role in enhancing vehicular safety and driving comfort by maintaining lane alignment and mitigating risks associated with driver distraction or drowsiness. These systems rely on sensor data to execute corrective steering or br...

Reactive Blue 21 Dye Degradation and Surface Modification of Cu and Ag/Cu Thin Films Prepared by Pulsed Laser Deposition
