One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that

Closing the Loop in Agrivoltaics: A Radiative Cooling Coating for Synergistic Self‐Cleaning and Water Harvesting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A nanostructured photonic‐thermal coating enables radiative‐cooling‐induced condensation and water harvesting, establishing a self‐sustaining agrivoltaics microclimate loop that transforms PV panels into active climate regulators. The integration of photovoltaic (PV) panels into agricultural landscapes (i.e., agrivoltaics) offers a promising path for ...

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Synergistic effects of silica fume, nanomaterials and inorganic salts on the hydration and compressive strength of low-density oil well cement slurry

open access: yesCement
During offshore cementing at shallow depth, the low-temperature environment at the bottom of the sea and the low-density requirement of the cement slurry significantly hinder the strength development of oil well cement systems.

Betaine‐, xylitol‐, and extra virgin olive oil–based toothpaste modulates inflammation and oral nitric oxide pathway: Clinical trial in gingivitis

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Gingivitis is a prevalent and reversible inflammatory condition driven by microbial dysbiosis. Beyond plaque control, interest has grown in oral hygiene formulations capable of modulating inflammation while preserving key microbial functions. Extra virgin olive oil (EVOO), together with xylitol and betaine, has demonstrated clinical

Liquid Crystal Elastomers Filaments for Adaptive Textiles and Soft Robotics: A Processing‐Centric Review

open access: yesMacromolecular Rapid Communications, EarlyView.
Liquid crystal elastomer (LCE) filaments are fabricated through extrusion with in‐process UV curing, enabling controlled flow alignment and network locking of mesogens. The resulting structure responds to thermal or optical stimuli, inducing molecular reorientation and macroscopic contraction.
