Potassium‐Doped Borophane Nanosheets: A Multifunctional Platform for Reversible Hydrogen Storage and Metal‐Free Hydrogen Transfer

open access: yesSmall, EarlyView.
Borophane in dual roles: as a reductant in the conversion of levulinic acid to γ‐valerolactone and as a reversible hydrogen reservoir through partial rehydrogenation. ABSTRACT 2D borophene has long been proposed as a promising hydrogen storage material, but experimental demonstrations remain limited to boron hydride sheets derived from MgB2.

LaNi5 hydride cryogenic refrigerator test results [PDF]

open access: yes, 1983
A complete LaNi5 hydrogen absorption cryogenic refrigerator system was developed. The system uses low temperature waste heat of approximately 100 C as a power source, and has no moving parts other than self operating valves.

Biomass Polymer‐Stabilized Hygroscopic Salts in Cellulose Foams for Durable Atmospheric Water Harvesting

open access: yesSmall Methods, EarlyView.
We fabricate a LiCl+CMC@cellulose composite foam via a scalable impregnation process, enabling excellent AWH water capture‐release cycling stability. The CMC acts as a “molecular glue,” effectively mitigating salt aggregation and leakage. The composite foam delivers a high water uptake of 16.04 ± 0.82 g g−1 with >80% retention over 10 cycles, while a ...

Cyclic Loading and Fabric Evolution in Sand: A Constitutive Investigation [PDF]

open access: yes, 2015
An anisotropic plasticity model is proposed to describe the effect of fabric and fabric evolution on the cyclic behaviour of sand within the framework of anisotropic critical state theory.

Innovation in the Spaces In‐Between: Creating the Nexus Between Human and Non‐Human Actors in Systemic Innovations

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT By combining theories of system thinking with a post‐humanist approach, we established a nexus between human and non‐human systems in the examination of systemic innovation. By doing so, we shed light on the interdependencies that exist between human and non‐human systems and contribute theoretically as well as methodologically to theories on ...

Modeling the Thermal Properties of Hydrogen‐Based Direct Reduced Iron Using Computational Thermodynamics and Machine Learning

open access: yessteel research international, EarlyView.
Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.

Preliminary Study on Unit Commitment for Renewable Energy Integration Considering Operation Cost and Life Cycle Assessment

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Most countries, including Japan, are focused on achieving net‐zero greenhouse gas (GHG) emissions by 2050, which requires quick action. Despite the increasing level of renewable power generation in power grids, fossil fuel power plants still have a significant role in producing GHG emissions, causing serious environmental issues.

Semen Cryopreservation in Testicular Cancer: Before or After Orchidectomy?

open access: yesAndrology, EarlyView.
ABSTRACT Background Fertility preservation in patients with testicular cancer remains a clinical priority, yet the optimal timing for sperm cryopreservation—before or after orchidectomy—remains a matter of debate. Objectives The aim of this study was to determine the optimal timing for semen cryopreservation and the best‐quality sample for ART.

Microfluidic Intracytoplasmic Sperm Injection (MICSI): A Novel Platform for Sperm Isolation, Selection, and Injection Into Oocytes

open access: yesAndrology, EarlyView.
ABSTRACT Background Infertility is a pressing global health concern, affecting one in six couples worldwide. The failure rate for assisted reproductive technologies (ART) cycles remains at approximately 78%, with limited improvements often attributed to a lack of technological innovation.
