Targeting online sales through last‐mile delivery platform integration

open access: yesJournal of Operations Management, Volume 71, Issue 2, Page 195-219, March 2025.
Abstract We analyze channel integration between a last‐mile delivery platform and a general merchandise retailer in two distinct stages: (1) platform delivery access (PDA), where the retailer continues to offer standard delivery through its own website but directs customers to the platform's website for new same‐day delivery; and (2) integrated ...

Microemulsion‐Based Drilling Fluids Incorporating Seashell Residue Powder: A Sustainable Approach to Fluid Loss Control

open access: yesJournal of Surfactants and Detergents, EarlyView.
Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.

Bed‐level tools for monitoring erosion and accretion patterns: Flume validation and field testing

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Monitoring short‐term changes in surface sediment elevation is fundamental to understanding erosion, transport, and deposition dynamics in shallow coastal environments. However, commonly used field approaches, such as horizontal markers, sediment erosion tables, subsurface sediment plates, or erosion pins, are not always cross‐validated under ...

Open letter: The need for a site‐based biodiversity standard measuring and certifying impacts from nature‐based projects

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Despite growing investment in restoration, weak accountability and poor biodiversity monitoring mean many projects fail to achieve ecological recovery. The Global Biodiversity Standard (TGBS) offers a practical way to ensure that restoration finance delivers measurable gains for nature.
