Environmentally Friendly Pervious Concrete for Treating Deicer-Laden Stormwater: Phase I [PDF]

open access: yes, 2015
A graphene oxide-modified pervious concrete was developed by using low-reactivity, high-calcium fly ash as sole binder and chemical activators and other admixtures.

Mechanical properties and thermal behaviour of two-stage concrete containing palm oil fuel ash [PDF]

open access: yes, 2017
Two-stage concrete (TSC) is a special type of concrete which is made by placing coarse aggregate in a formwork and injecting a grout either by pump or under the gravity force to fill the voids. Over the decades, the application of supplementary cementing

Quasi‐Static Compression Response and Energy Absorption of CNTF/EP Origami Thin‐Walled Tubes

open access: yesAdvanced Materials Interfaces, EarlyView.
This research innovatively uses CNTF/EP composite material to fabricate origami thin‐walled tubes, investigating their quasi‐static compression deformation modes and performance. It examines the effects of introducing secondary creases on deformation modes and the energy absorption metrics of the thin‐walled tubes.

Prognostic factors in conversion surgery following nab‐paclitaxel with gemcitabine and subsequent chemoradiotherapy for unresectable locally advanced pancreatic cancer: Results of a dual‐center study

open access: yesAnnals of Gastroenterological Surgery, Volume 7, Issue 1, Page 157-166, January 2023., 2023
For radical surgery after induction gemcitabine along with nab‐paclitaxel and subsequent chemoradiotherapy for unresectable locally advanced pancreatic ductal adenocarcinoma, CA19‐9 normalization and maintenance of good nutritional status during treatment until surgery were important for prolonged prognosis.

The use of artificial neural networks in adiabatic curves modeling [PDF]

open access: yes, 2008
Adiabatic hydration curves are the most suitable data for temperature calculations in concrete hardening structures. However, it is very difficult to predict the adiabatic hydration curve of an arbitrary concrete mixture.

A Bilayer Micro/Nanostructured Water‐Based Paint With Effective Thermal Insulating and Reflective Properties

open access: yesAdvanced Materials Interfaces, EarlyView.
The design, optimization and characterization of a new bilayer painting system is presented. The underlying layer is engineered to provide exceptional thermal insulation through the synergistic effect of hollow perlite microspheres and micrometer‐sized cellulose particles. The external painting layer is designed to induce the formation of a homogeneous
