The Need for Fundamental Photovoltaics Research to Ensure Energy Security

Progress in Photovoltaics: Research and Applications, EarlyView.
The center of this graphic focuses on the core of this paper—that fundamental research is central to the continued development of the photovoltaic (PV) industry. To the left, we have depictions of what is being studied—PV materials, PV cell structures, and PV module structures.

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

Journal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Government Policies toward Information and Communication [PDF]

The development of what one might call 'modern' systems of information and communication began with the Gutenberg printing press in the 15th century, and progressed through the prepaid postal system, electric telegraph and telephone in the 19th century ...

Understanding Interactions Between Sustainable Development Goals Within and Between Policy Programmes: The Case of Kenya's Dairy Sector

Sustainable Development, EarlyView.
ABSTRACT Achieving Agenda 2030 depends on addressing interactions between the sustainable development goals (SDGs). In this paper, we conceptualize SDG interactions as synergies or trade‐offs, incoming or outgoing, and internal or external, and analyze how SDG 2 (Zero Hunger) interacts with other SDGs within and across policy programmes that support ...

Facing Obsolescence: Component Repair and Collaboration in the Independent ICT Commercial Repair Sector

Sustainable Development, EarlyView.
ABSTRACT Repairs are becoming more difficult to perform due to multiple factors, including obsolescence, complexity of designs, technological change and lack of information and spare parts. This underlines a conflict between repair and technological designs driven by accumulation logics that require increasing growth rates.

Shaping expectations, losing flexibility: A study of CEO promises as strategic communication tools

Strategic Management Journal, EarlyView.
Abstract Research Summary CEO promises are powerful but understudied communication tools. We develop a dual‐mechanism framework theorizing that while CEO promises elevate stakeholder expectations, they simultaneously constrain strategic flexibility. We argue that CEO promise‐making is shaped by two competing pressures: making more promises when the ...
