Multifunctional ionic liquid boosts the efficiency of hole transport layer‐free carbon‐based perovskite solar cells beyond 20%

FlexMat, EarlyView.
HTL‐free carbon‐based PSCs are promising in stability but limited by efficiency. Systematic screening identifies DMAFo as an optimized ionic‐liquid additive: the DMA+ regulates lattice distortion and relieves residual stress, while Fo‒ passivates halide vacancies, and ameliorates band‐alignment.

Syntheses and medicinal chemistry of spiro heterocyclic steroids

Beilstein Journal of Organic Chemistry
There is compelling evidence that incorporating a heterocyclic moiety into a steroid can alter its pharmacological and pharmacokinetic properties, driving intense interest in the synthesis of such hybrids among research groups. In this review, we present

UK Forecasts of Annual GDP: Their Accuracy and the Information Categories Underlying Their Revisions

Journal of Forecasting, EarlyView.
ABSTRACT Policy makers are concerned with the accuracy of GDP forecasts and want to understand the reasons for the revision of forecasts. We study these issues by examining forecasts of annual UK GDP growth by a panel of agents, published monthly by HM Treasury. We focus on two main issues: the developing accuracy of the group‐mean forecast as horizons

Patterns of Cervical Metastases and Implications for Neck Management in Minor Salivary Gland Cancer Treatment

Head &Neck, EarlyView.
ABSTRACT Objectives Minor salivary gland cancer (MiSGC) is a rare and heterogeneous disease, with different degrees of tumor aggressiveness. The scarce data in the literature show that the presence of lymph node metastases (LNMs) negatively impacts the prognosis.

Arsonic Acid Functional Polymers Enable Stabilization of Iron Oxide Nanoparticles in Aqueous Solution

Macromolecular Rapid Communications, EarlyView.
Arsonic acid containing diblock copolymers are developed to incorporate arsonic acid moieties for surface anchoring to IONPs, along with water soluble PEG blocks to impart colloidal stability in aqueous environments. The resulting polymer‐coated IONPs are evaluated for stability in physiological media and cytocompatibility.

Modulating Charge Carrier Dynamics Through Tailored Hole Transport Layers in Perovskite Photovoltaics

Nano Select, EarlyView.
This study investigates alternative hole transport materials (HTMs) for n‐i‐p perovskite solar cells, comparing Spiro‐OMeTAD, PTAA, P3HT, and H101. PTAA‐based devices achieve the highest efficiency (21.01%) by suppressing non‐radiative recombination at the perovskite/HTM interface, despite slower charge transfer.
