Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

open access: yesAdvanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

Effects of organic matter input on soil microbial properties and crop yields in conventional and organic cropping systems [PDF]

open access: yes, 2008
Unlike conventional cropping systems, which are characterised by targeted short-term fertility management, organic farming systems depend on long-term increase in soil fertility and promotion of soil biodiversity.

The Influence of Annealing on the Sb Layer in the Synthesis of [001]‐Oriented Sb2Se3 Film for Photoelectrochemical Hydrogen Gas Generation

open access: yesAdvanced Functional Materials, EarlyView.
[001]‐oriented Sb2Se3 film with improved crystallinity and adjusted composition is achieved via a new thermal treatment approach consisting of preliminary annealing of the Sb layer before its selenization. The findings of this work demonstrate enhanced charge carriers' transportation, a stable performance, and an improvement of H2 generation from ...

الاكتئاب لدى النساء Editor of ArabiXiv assistant Professor associate Professor Professor associate Professor Professor

open access: yes
يعد الاكتئاب، بمختلف أنواعه، من أكثر الاضطرابات النفسية انتشاراً وشدة، ومن أعراضه افتقاد المكتئبين لمعنى الحياة وتعكر مزاجهم والشعور باليأس والتعاسة والمعاناة والأرق وفقدان الأمل بالحياة من كل شيء، وقد ينتهي الاكتئاب بالانتحار في كثير من الحالات (15% وفقاً لبعض الدراسات والإحصائيات).

Combinatorial Identities from the Spectral Theory of Quantum Graphs

open access: yes, 2000
We present a few combinatorial identities which were encountered in our work on the spectral theory of quantum graphs. They establish a new connection between the theory of random matrix ensembles and combinatorics.Comment: 16 pages, RevTeX, 1 ...

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

open access: yesAdvanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

السلوك الصحي والاتجاهات نحو الصحة assistant Professor associate Professor Professor associate Professor Professor

open access: yes
هدفت هذه الدراسة إلى تحليل السلوك الصحي والاتجاهات الصحية للطّلاب من منظور عبر ثقافي بهدف إيجاد فروق عبر ثقافية بين عينةِ سوريةِ وألمانيةِ. استخدم في الدراسة استبيان السلوك الصحي ، (Steptoe, 1991) الذي يقيس مظاهر معينة من السلوك الصحي والاتجاهات نحوه. اشتملت عينة الدراسة على 300 مفحوص كان بينهم 201 أنثى (67%) و 99 ذكر (33%).

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.
