In‐Situ Solution Complexation for n‐Type Surface‐Energetics Reconstruction in 2.0 eV Ultra‐Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
A reactive in situ solution complexation strategy reconstructs the surface of 2.0 eV ultra‐wide‐bandgap perovskites via proton transfer. This chemical modulation eliminates metallic defects and induces a degenerate‐like n‐type surface, establishing an Ohmic tunneling contact.

An Invariant Cost Model for the Lambda Calculus

open access: yes, 2005
We define a new cost model for the call-by-value lambda-calculus satisfying the invariance thesis. That is, under the proposed cost model, Turing machines and the call-by-value lambda-calculus can simulate each other within a polynomial time overhead ...

A Theory of Explicit Substitutions with Safe and Full Composition

open access: yes, 2009
Many different systems with explicit substitutions have been proposed to implement a large class of higher-order languages. Motivations and challenges that guided the development of such calculi in functional frameworks are surveyed in the first part of ...

The Role of Ultra‐Thin Buffer Layers for Achieving Ultra‐Low Dark Currents in Single‐Component Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
Here, SubNc single‐component organic photodiodes (SC‐OPDs) are investigated, which achieve highly competitive performance metrics, including high EQE, ultra‐low JD, and high specific detectivity (D*). This study emphasizes the critical role of an organic buffer layer in studying the interface energetics and effects to achieve state‐of‐the‐art ...

C, Lambda Calculus and Compiler Verification - a study in Haskell of purely-functional techniques for a formal specification of imperative programming languages and an epistemically-sound verification of their compilers

open access: yes, 2011
Formal verification of a compiler is a long-standing problem in computer science and, although recent years have seen substantial achievements in the area, most of the proposed solutions do not scale very well with the complexity of modern software development environments.

Multiplex Modular Nanorobotic Systems with Catalytic Activity under Magnetic Navigation

open access: yesAdvanced Functional Materials, EarlyView.
We present modular nanorobots composed of a magnetic propulsion module and different extension modules carrying functional activities, assembled via DNA base pairing. The system integrates propulsion, optical tracking, enzymatic catalysis, and cell docking in a programmable manner.

On generic context lemmas for lambda calculi with sharing [PDF]

open access: yes, 2007
This paper proves several generic variants of context lemmas and thus contributes to improving the tools to develop observational semantics that is based on a reduction semantics for a language.

Probabilistic Operational Semantics for the Lambda Calculus

open access: yes, 2011
Probabilistic operational semantics for a nondeterministic extension of pure lambda calculus is studied. In this semantics, a term evaluates to a (finite or infinite) distribution of values.

Intrinsic Photoactive Star ZnPc–Poly(glutamate) Nanoplatforms for Multimodal Glioblastoma Therapy and Brain‐Targeted Delivery

open access: yesAdvanced Functional Materials, EarlyView.
An intrinsic photoactive star‐shaped zinc phtalocyanine‐poly(L‐glutamic acid) (ZnPc‐PGA) nanoplatform for multimodal glioblastoma (GBM) therapy and brain‐targeted elivery. A ZnPc‐PGA‐based multifunctional theranostic nanocarrier platform enables image‐guided, multimodal GBM therapy. ZnPc‐PGA nanocarriers support the integration of fluorescence imaging,
