rearranging them to form the other one. Hilbert’s third problem asked whether such a proof could be devised for tetrahedra. But his real interest was in the metamathematical question of whether the use of calculus was necessary. This was the first of his problems to be solved. In 1902, Max Dehn showed that calculus was needed. Two of Hilbert’s problems have, famously, had metamathematical solutions. His first problem was to prove or disprove Cantor’s continuum hypothesis, which is the statement… 

Orientational dynamics and energy landscape features of thermotropic liquid crystals: An analogy with supercooled liquids

Recent optical kerr effect (OKE) studies have revealed that orientational relaxation of rodlike nematogens near the isotropic-nematic (I-N) phase boundary and also in the nematic phase exhibit

Rational Design of Atomic Site Catalysts for Electrocatalytic Nitrogen Reduction Reaction: One Step Closer to Optimum Activity and Selectivity

The electrocatalytic nitrogen reduction reaction (NRR) has been one of the most intriguing catalytic reactions in recent years, providing an energy-saving and environmentally friendly alternative to

Rigid anchoring of highly crystallized and uniformly dispersed Pd nanocrystals on carbon fibers for ambient electrocatalytic reduction of nitrogen to ammonia.

Density functional theory (DFT) calculations reveal that the rationality of the distal associative mechanism on PdNCs@CNFs and Pd nanocrystals on the surface of Pd NCs@ CNFs is more favorable for nitrogen (N2) molecule adsorption and polarization.

Single transition metal atom embedded into a MoS2 nanosheet as a promising catalyst for electrochemical ammonia synthesis.

The single Mo atom embedded into the MoS2 nanosheet was found to be the most active catalyst for NRR with an onset potential of -0.53 V, in which the hydrogenation of the adsorbed N2* to N2H* is the potential-determining step.

Development of Organic Farming in Europe at the Crossroads: Looking for the Way Forward Through System Archetypes Lenses

Over the last several decades, policymakers and stakeholders in the European Union (EU) have put considerable effort into increasing the adoption of organic farming, with the overall objective of its

Agroforestry and organic agriculture

Current conventional agriculture is considered unsustainable and inadequate to address great societal challenges such as climate change, environmental pollution, food security, dependence on fossil

Efficient delay reduction by the virtual path schemes in internet networks

Through studies, it has been found out that organic agriculture does more than just producing safe food sources, it also assist in the alleviation of the global economy's status with regards employment and other issues as such.

Organic agriculture in the twenty-first century

Although organic agriculture has an untapped role to play when it comes to the establishment of sustainable farming systems, no single approach will safely feed the planet and a blend of organic and other innovative farming systems is needed.

Potential-Driven Restructuring of Cu Single Atoms to Nanoparticles for Boosting the Electrochemical Reduction of Nitrate to Ammonia.

Restructuring is ubiquitous in thermocatalysis and of pivotal importance to identify the real active site, yet it is less explored in electrocatalysis. Herein, by using operando X-ray absorption

Food security and biodiversity: can we have both? An agroecological analysis

We present an extensive literature review exploring the relationships between food insecurity and rapid biodiversity loss, and the competing methods proposed to address each of these serious
