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

Advanced 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,

Achieving High ON State Current through Ferroelectric Polarization‐Dependent Interfacial Resistance Switching in Undoped Orthorhombic HfO2 Films

Advanced Functional Materials, EarlyView.
Ferroelectric tunnel junction devices based on epitaxial undoped ferroelectric HfO2 films demonstrate stable switching endurance of over 106 switching cycles, low write voltages of ±3 V, 16 measured resistance states, and neuromorphic capability.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites

Advanced Functional Materials, EarlyView.
We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene

Advanced Functional Materials, EarlyView.
Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

Introduction to the species’ accounts

1998
The morphometrical information is presented per species or per species complex. The sequence of chapters follows Voous’ (1973) species order. The spelling of the American names of species follows Hayman et al. (1986). Each chapter starts with describing the breeding distribution and the present-day knowledge on morphometrical variation and systematics.

Introduction to the Species Problem

2016
Species concepts, or more generally, the species problem, are among the most debated issues in biology. Answers to the questions of what a species is, in what ways species really exist (if in fact they do) and how species can not only be defined but also recognized and delimited, belong at least as much, and some of them rather more, to the realm of ...

Species Introductions to Hawaii

1986
What determines whether species have the potential to invade new environments? And how should we evaluate community properties to determine whether a biological system is vulnerable to invasion? These questions are fundamental to a basic understanding of the structure of ecological communities.

Introduction to Species of Structures

1997
Introduction This chapter contains the basic concepts of the combinatorial theory of species of structures. It is an indispensable starting point for the developments and applications presented in the subsequent chapters. We begin with some general considerations on the notion of structure, everywhere present in mathematics and theoretical computer ...
