Corporate social responsibility and employee motivation: intrinsic and extrinsic pathways in Vietnamese SMEs

Purpose This study aims to conceptualize corporate social responsibility (CSR) as a potentially need-supportive organizational context. This study examines how CSR-related autonomy, competence and relatedness are associated with employees’ intrinsic and extrinsic motivation and h...

CFD investigation of enhanced heat transfer using periodically spherical-expanded tube

Passive heat transfer enhancement can improve heat exchanger performance without additional energy consumption. This study numerically investigates the heat transfer, flow characteristics, and thermal-hydraulic performance of a periodically spherical-expanded tube under turbulent...

Metal Active‐Site Engineering in High‐Entropy Catalysts for Catalytic Applications

High-entropy catalysts (HECs), including high-entropy alloys and high-entropy oxides, have emerged as a transformative class of catalytic materials owing to their exceptional compositional flexibility and entropy-stabilized structures. Unlike conventional catalysts, HECs possess...

Insertion into Donor–Acceptor Cyclopropanes with Carbon–Sulfur Moieties Derived from Sulfoxonium Ylides and Elemental Sulfur

Abstract The (3 + 2) cycloaddition of donor–acceptor cyclopropanes (DACs) with carbon–sulfur 2π components has become an emerging method to rapidly assemble tetrahydrothiophenes. Starting materials donating the carbon–sulfur unit are often isolated from thionation of carbonyls or...

Data-Driven Identification of GelMA Hydrogel Formulations with Bioink-Relevant Properties Using Design of Experiments (DoE) and Machine Learning (ML)

Abstract Gelatin methacryloyl (GelMA) hydrogels are promising bioink candidates for extrusion-based 3D bioprinting, but their synthesis and formulation conditions must be optimized to achieve suitable gelation, printability, and mechanical stability. In our study, a design-of-exp...

Evaluating operational efficiency and hydrogen sulfide mitigation in fluidized bed co-gasification of sewage sludge

This study investigated the operational efficiency and in situ H 2 S mitigation of municipal sludge (MS) co-gasification with drinking water treatment sludge (DWTS) in a lab-scale fluidized-bed reactor. Gasification experiments were performed at 700–900 °C, ER 0.2–0.4, and 10–20...

Social housing as a pathway to sustainable development in Vietnam: an SDG-based analytical framework

Purpose Social housing (SH) plays an essential role in addressing housing needs in rapidly urbanizing countries. In Vietnam, policy discussions primarily emphasize affordability and housing supply targets. However, limited attention is given to the broader developmental functions...

Higher-order phase-field isogeometric analysis for homogenization of porous media: A multi-patch comparative framework

Computational homogenization of porous media is often hindered by the complexity of mesh generation. While isogeometric analysis (IGA) mitigates geometric errors, multi-patch parameterization for internal voids remains cumbersome. This paper introduces a single-patch, higher-orde...

Linking eco-design and digital competence for better social performance with moderation of integrated construction supply chain

Purpose This study aims to investigate the impacts of eco-design (EDS) and integrated supply chain (ISC) on social performance (SPF), the mediating role of EDS in the linkage of digital competence (DC) and SPF and the moderating role of ISC in the EDS-SPF relationship in construc...

Carbon‑paper‑supported Fe‑doped WO3 catalysts engineered as a high‑performance bifunctional electrode for alkaline water splitting

Tungsten trioxide (WO 3 ) is an earth‑abundant and chemically robust semiconductor predominantly explored as a photoanode. A key limitation in earlier WO 3 studies is the reliance on fluorine‑doped tin oxide (FTO) substrates, whose flat 2D geometry, moderate conductivity, and sus...

Comparative study of the rotating bending fatigue performance of wire arc additively manufactured hollow shafts with and without TIG pre-joining

This study investigates the effect of Tungsten Inert Gas (TIG) pre-joining on the rotating bending fatigue performance of hollow shafts fabricated by Wire Arc Additive Manufacturing (WAAM) from ER70S-6 wire deposited onto stacked CCT34 low-carbon steel substrate rings. A four-fac...

pH-responsive dual-layered chitosan/Tween 80 nanoemulsions for gastrointestinal targeted delivery of curcumin

Abstract Curcumin's application is severely hindered by its hydrophobicity, poor solubility and rapid degradation. This study developed a pH-responsive, dual-layered curcumin-chitosan nanoemulsion (nCCURs) system using the phase inversion temperature method coupled with probe ult...

Comparative periodate/peroxydisulfate‐induced catalytic degradation of C ongo red by CuS / AC catalyst and its composite membrane with polysulfone

Abstract The rational design of high‐performance, self‐cleaning catalytic membranes is critical for overcoming severe fouling and mass‐transfer limitations in wastewater treatment. This study reports the successful synthesis of a CuS/activated carbon (CuS/AC) composite and its in...

A multi-objective constraint programming–satisfiability model for non-unit repetitive construction scheduling

Non-unit repetitive construction projects, in which activity groups are repeatedly executed over work-group-specific units rather than over a common set of identical production units, are difficult to schedule because activity sequences, crew movements, and execution logic vary a...

Size and shape of fuzzy spheres from matrix/membrane correspondence

Abstract We study the size and shape statistics of ground state fuzzy spheres when projected onto the transverse plane, utilizing the regularized SU(N = 2) matrix model in D = (1 + 3)-dimensional spacetime. We show that they appear as ellipses, from matrix/membrane correspondence...

Evidence of hydrodynamic control of phytoplankton seasonality in a tropical urban estuary

Tropical urban estuaries receive year-round nutrient loads, yet their strongest phytoplankton blooms often occur in the dry season. The proximate control on this seasonality remains unresolved in wastewater-impacted tropical systems. Here we apply a transient one-dimensional Carb...

Supporting sustainable building development through BIM-enabled life cycle assessment: evidence from Vietnam

Purpose This study aims to develop and validate a building information modeling (BIM)-enabled life cycle assessment (LCA) framework for quantifying and reducing the environmental impacts of buildings during the design stage. The research addresses the limited implementation of BI...

Behavioral mechanisms of traffic congestion in motorized-dominated cities: Insights from street-level observations in Ho Chi Minh City

Urban traffic congestion in motorcycle-dependent cities such as Ho Chi Minh City (HCMC) is often examined through infrastructure capacity, traffic volume, or intersection performance. However, these approaches can overlook the behavioral and spatial dynamics embedded in everyday...
