Advanced Materials, EarlyView.In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

A Unified Model of Investment Under Uncertainty [PDF]
This paper extends the theory of investment under uncertainty to incorporate fixed costs of investment, a wedge between the purchase price and sale price of capital, and potential irreversibility of investment. In this extended framework, investment is a

Advanced Materials, EarlyView.A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

Post-Manichean Economics: Foreign Investment, State Capacity and Economic Development in Transition Economies [PDF]
This paper evaluates the role of foreign direct investment (FDI) in the transition from socialism to capitalism. Fixed-effects panel regressions indicate that FDI and domestic investment have an equal effect on growth in the first year of investment, but

Adaptive Twisting Metamaterials
Advanced Materials, EarlyView.This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Energy‐Efficient, Sustainable Cascade Glucose Electrooxidation into Glucaric Acid
Advanced Materials, EarlyView.This study presents a tandem system that efficiently converts glucose into glucaric acid while generating renewable electricity. By decoupling the oxidation process into two cascaded steps, the system achieves an overall 90% Faradaic efficiency and 80% conversion efficiency at ∼0.6 VRHE, significantly reducing energy consumption compared to traditional

Perspective on Aqueous Batteries: Historical Milestones and Modern Revival
Advanced Materials, EarlyView.This review retraces the development of aqueous batteries from classical Zn‐MnO2 chemistry to modern Zn and Ni systems, correlating voltage, capacity, and electrolyte formulation with practical performance. By mapping historical success and failure onto current and future research directions, it identifies guiding principles that steer the design of ...
