On the Ubiquitous Nature of the Agglomeration Economies and their Diverse Determinants: Some Notes. [PDF]

open access: yes
This highly preliminary work attempts to study the multiple drivers of agglomeration phenomena in contemporary economies. First, we propose a tentative taxonomy of agglomeration drivers in which the conditions of knowledge accumulation play a paramount ...

Ultra‐White Elastomeric Coatings for Daytime Radiative Cooling

open access: yesAdvanced Materials Technologies, EarlyView.
Passive daytime radiative cooling meets elasticity in a new class of ultra‐white silicone coatings. Combining high solar reflectance with strong sky‐window emission, they hold surfaces below ambient temperature under full sunlight while remaining flexible and stretchable. This combination of cooling performance and mechanical flexibility enables energy‐

Programmable Variable‐Stiffness Multilayer Elastomer Composites With High‐Aspect‐Ratio Low‐Melting‐Point Alloy Inclusions

open access: yesAdvanced Materials Technologies, EarlyView.
High‐aspect‐ratio low‐melting‐point alloy inclusions are embedded within multilayer silicone laminates to create thermally programmable stiffness. Sequential activation of alloy‐rich layers produces four distinct mechanical states and reconfigures tendon‐driven actuator trajectories under the same load.

Agglomeration Economies and Local Comovement of Stock Returns [PDF]

open access: yes
Existing studies in finance have documented the comovement of stock returns of companies headquartered in the same location. The interpretation is that local investors have a “local bias” due to an information advantage on local companies.

In Situ Formation of Ni‐P‐O‐C Interfaces in DLP‐Printed Carbon Microlattices for Efficient Alkaline Hydrogen Evolution

open access: yesAdvanced Materials Technologies, EarlyView.
Graphical abstract illustrating the fabrication of Ni–P–O–C porous carbon microlattice electrodes by DLP printing of Ni/P precursor‐containing resin followed by high‐temperature carbonization. The resulting conductive microlattice acts directly as the HER cathode in alkaline electrolyte, where in situ formed Ni–P–O–C interfaces provide active sites for

Rise And Fall Of Cities, Measuring Spatial Clustering And Economies Of Urban Agglomeration In West Java [PDF]

open access: yes
With others neighboring Provinces in the western part of Java, the West Java Province shares the southeast Asian most densely urban area (Bodebek as part of Jabodetabek and Greater Bandung). This research tries to identify the spatial clustering of urban

Copper Electroplated TPMS Polymer Lattices for Lightweight Absorption Dominant Electromagnetic Interference Shielding

open access: yesAdvanced Materials Technologies, EarlyView.
Copper electroplating transforms lightweight 3D‐printed TPMS polymer lattices into effective electromagnetic shields. Topology, relative density, and conductive seed layer continuity govern copper penetration, electrical resistance, and attenuation. SEA consistently exceeds SER, while 35% RD Diamond lattice gives the best performance, reaching 48.72 dB
