Invoking civil rights may actually hurt public support for social causes, new study finds

Framing a cause as a “civil rights” issue may actually decrease public support—even among people who deeply value civil rights. That’s the key finding of a new study published in the American Sociological Review, which challenges long-held beliefs about how best to win public backing for social change. Researchers found that Americans generally feel very positively about the idea of civil rights, in the abstract. However, in describing contemporary issues—like workplace discrimination, food insecurity or ...

New 3D-printing method makes two materials from one resin

One-pot recipes make preparing meals quick and easy. And one-pot 3D-printing could do the same for additive manufacturing. Now, researchers publishing in ACS Central Science have demonstrated a new resin that simultaneously creates solid objects and dissolvable structural supports, depending on what type of light the resin is exposed to. The approach could increase the applications for 3D-printed objects, including tissue engineering scaffolds, joints and hinges. “Vat photopolymerization is known for its fast and high-resolution printing, but one of the most nerve-wracking parts after printing is manually removing supports for intricate interlocking and overhang ...

How to create aqueous 100 nm-sized materials with polycavities

While molecues with a single cavity have been extensively studied in solution, the solution state functions of polycavity materials remain elusive owing to their synthetic inaccessibility. Porous aromatic polymers (PAPs) are synthesized in a single step and offer polymeric cavity frameworks with high stability, which are applicable to gas and molecule adsorption/separation only in the solid state. Due to their strong aggregation-derived insoubility, unsubstituted PAPs cannot be used in any solvent until now. To move the functions of PAPs from the solid to the solution ...

Rice researchers lay groundwork for designer hybrid 2D materials

HOUSTON – (May 28, 2025) – Some of the most promising materials for future technologies come in layers just one atom thick ⎯ graphene, e.g., a sheet of carbon atoms arranged in a hexagonal lattice, prized for its exceptional strength and conductivity. While hundreds of such materials exist, truly merging them into something new has remained a challenge. Most efforts simply stack these atom-thin sheets like a deck of cards, but the layers typically lack significant interaction between them. An international team of researchers led by Rice University ...

‘Hopelessly attached’: Scientists discover new 2D material that sticks the landing

HOUSTON – (May 23, 2025) – More than ten years ago, researchers at Rice University led by materials scientist Boris Yakobson predicted that boron atoms would cling too tightly to copper to form borophene, a flexible, metallic two-dimensional material with potential across electronics, energy and catalysis. Now, new research shows that prediction holds up, but not in the way anyone expected. Unlike systems such as graphene on copper, where atoms may diffuse into the substrate without forming a distinct alloy, the ...
