Plant-Based Structures as an Opportunity to Engineer Optical Functions in Next-Generation Light Management

Autor: Joice Jaqueline, Kaschuk, Yazan, Al Haj, Orlando J, Rojas, Kati, Miettunen, Tiffany, Abitbol, Jaana, Vapaavuori

Publikováno v: Advanced materials (Deerfield Beach, Fla.). 34(6)

This review addresses the reconstruction of structural plant components (cellulose, lignin, and hemicelluloses) into materials displaying advanced optical properties. The strategies to isolate the main building blocks are discussed, and the effects o

Nitrogen-doped graphene encapsulated cobalt iron sulfide as an advanced electrode for high-performance asymmetric supercapacitors

Autor: Joong Hee Lee, Jayaraman Balamurugan, Nam Hoon Kim, Yazan Al Haj

Publikováno v: Journal of Materials Chemistry A. 7:3941-3952

To develop supercapacitors (SCs) with high energy and power densities, a new type of electrode material with unique properties is strongly required. Metal sulfides (MSs) have been recently studied as promising electrode materials for high-performance

Ni-Cd carbon nanofibers as an effective catalyst for urea fuel cell

Autor: Mohannad Alajami, Hussain Alawadhi, Nasser A.M. Barakat, Yazan Al Haj, Mohammad Ali Abdelkareem

Publikováno v: Journal of Environmental Chemical Engineering. 6:332-337

One of the main challenges facing the development of urea fuel cells is the low catalytic activity of the anode. Ni decorated carbon nano-fiber is a promising anode catalyst in urea fuel cells. In this study, we have investigated the effect of Cd dop

Enhanced onset potential NiMn-decorated activated carbon as effective and applicable anode in urea fuel cells

Autor: Yazan Al Haj, Mohannad Alajami, Saeed Al-Meer, Nasser A.M. Barakat, M. Obaid

Publikováno v: Catalysis Communications. 97:32-36

Basically, to be used as an anode in the air-cathode fuel cells, the onset potential of the introduced material should be lower than the ORR potential. Unfortunately, especially in the field of urea fuel cells, most of the reported electrocatalysts d
