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.

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Doing Quantitative Grounded Theory: A theory of trapped travel consumption

open access: yesGrounded Theory Review: An International Journal, 2008
All is data. Grounded theorists employ this sentence in their quest to create original theoretical frameworks. Yet researchers typically interpret the word gdatah to mean qualitative data or, more specifically, interview data collected from respondents.

From the Editor's Desk

open access: yesGrounded Theory Review: An International Journal, 2020
The Grounded Theory Review focuses solely on classic grounded theories and methodological papers. Novice or lay readers may be unaware of the subtle elements that indicate a good classic theory.

Understanding Decoherence of the Boron Vacancy Center in Hexagonal Boron Nitride

open access: yesAdvanced Functional Materials, EarlyView.
State‐of‐the‐art computations unravel the intricate decoherence dynamics of the boron vacancy center in hexagonal boron nitride across magnetic fields from 0 to 3 T. Five distinct regimes emerge, dominated by nuclear spin interactions, revealing optimal coherence times of 1–20 µs in the 180–350 mT range for isotopically pure samples.

Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

The Future of Grounded Theory

open access: yesGrounded Theory Review: An International Journal, 2010
I would like to speak about what I consider the future of grounded theory. I will discuss in whose hands the future of grounded theory appears to be and what accounts for its spread, its use and misuse, and where the majority of grounded theory studies ...

Using In Situ TEM to Understand the Surfaces of Electrocatalysts at Reaction Conditions: Single‐Atoms to Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
This review summarizes recent advances in closed‐cell in situ TEM strategies for accurate determination of the activity and stability of single‐atom catalyst systems during operation. Operando conditions causing dynamic changes of SAC systems are highlighted and we explain why ensemble average‐based optical techniques may benefit from the technological

Theoretical Writing

open access: yesGrounded Theory Review: An International Journal, 2009
Theoretical sorting has brought the analyst to the point of pent-up pressure to write: to see the months of work actualized in a “piece.” But this is only a personal pressure.

Developing a Classic Grounded Theory Research Study Protocol

open access: yesGrounded Theory Review: An International Journal, 2023
The research study protocol is a roadmap for conducting research systematically, efficiently, and ethically. While protocols have standard components, a classic grounded theory protocol differs in its methods, including processes and procedures, because of the uniqueness of the methodology.
