Light Up a Nanocluster

open access: yesAggregate, Volume 7, Issue 1, January 2026.
Atomically precise metal nanoclusters are ultrasmall aggregates of metal atoms with finely tunable structures. They exhibit broad PL across visible to NIR wavelengths by tuning size, structure, and composition. The review addresses fundamental emission mechanisms and structure–property correlations, evaluating enhancement strategies (ligand ...

Lithium Nitrate Effects for Lithium‐Based Chemical Batteries: A Review

open access: yesCarbon Energy, Volume 8, Issue 1, January 2026.
Lithium nitrate (LiNO3) has been widely used to address uneven Li plating/stripping and stabilize the Li/electrolyte interface, and to date, many strategies on how to use nitrates have been explored. This review focuses attention on the effects of LiNO3 in lithium‐based batteries, aiming to provide scientific guidance for the optimization of electrode ...

Shock‐Triggered Asymmetric Response Stochastic Volatility

open access: yesJournal of Forecasting, Volume 45, Issue 1, Page 217-240, January 2026.
ABSTRACT We propose a novel asymmetric stochastic volatility model (STAR‐SV) in which the leverage parameter adjusts to the magnitude of past shocks. This flexible specification captures both the leverage effects and their propagation more effectively than standard asymmetric volatility models.

Researchers' Views on Preprints and Open Access Publishing: Results From a Free‐Answer Survey of Japanese Molecular Biologists

open access: yesLearned Publishing, Volume 39, Issue 1, January 2026.
ABSTRACT A survey conducted in 2022 amongst members of the Molecular Biology Society of Japan (n = 633) about preprints and open access journals included qualitative data from free‐response answers (n = 161). Analysis of the free‐form responses suggests that researchers believe that peer review of papers is the foundation for ensuring the credibility ...
